The establishment of national parks in Brazil has been made based on a history of conflicts with local populations living within the limits or buffer zones of protected areas. These conflicts begin with disputes over territorial ownership. They affect local livelihoods, access to and use of space and natural resources, and create power asymmetries. In response to these conflicts, the Federal Conservation Agency has put forward norms that guarantee inclusive arenas for local people to take part in negotiations with park managers. In this study, environmental conflicts caused by the implementation of parks overlapping local population territories are analyzed aiming to understand their role as mechanisms promoting institutional changes. We collected data from two communities that overlap the Serra da Bocaina National Park through interviews, workshops, and direct observations. For each community, we characterized conflicts involving the community and Park officers. We identified consequences to the community’s livelihoods and analyzed their influence on institutional change. The results suggest that one community responded to conservation conflicts through actions towards negotiation and collaboration with the national park. The other community promoted changes in agricultural production methods and sought new markets as a strategy for staying in the territory. Conflicts are effective as a mechanism for institutional changes, as local actors articulate with autonomous organizations at different levels. We highlight the importance of a continuous documentation on conflicts and their consequences to rural livelihoods in both communities and conflict management actions taken by the Park in the long term., Highlights Conflicts are mechanisms that can promote institutional change.Disputed parks and communities territories can stimulate arenas for negotiation.Conflict outcomes in no-take protected areas can strengthen community empowerment.Multiple scale networks and community empowerment facilitate institutional changes.Documentation of environmental conflicts contributes to an adaptive management process.

Understanding the extent of human–primate conflict in areas where habitat overlap reaches at maximum level between local farmers and primates is crucial to developing conservation and management strategies. One of the threats of southern geladas (Theropithecus gelada obscurus) is conflict with the local farmers due to cereal crop raiding. This study was carried out to compare the intensity of human–gelada conflicts and the attitude of local farmers toward the conservation of geladas among local communities neighboring Borena Sayint National Park (BSNP) and an unprotected site far from the BSNP. Data from 356 randomly selected respondents were collected using questionnaire interview method. Overall, 92.13% of the respondents considered southern geladas as cereal crop pests. Those major complaints against geladas did not differ significantly between the two study sites: crop raiding (p = 0.435) and competition with livestock for pasture (p = 0.990). Overall, 61.78% of the respondents surrounding the Park had positive attitude while 60.00% from the unprotected villages had negative attitude toward geladas, and the difference was significant (p

Agricultural emissions are the primary source of ammonia (NH3) deposition in Rocky Mountain National Park (RMNP), a Class I area, that is granted special air quality protections under the Clean Air Act. Between 2014 and 2016, the pilot phase of the Colorado agricultural nitrogen early warning system (CANEWS) was developed for agricultural producers to voluntarily and temporarily minimize emissions of NH3 during periods of upslope winds. The CANEWS was created using trajectory analyses driven by outputs from an ensemble of numerical weather forecasts together with the climatological expertize of human forecasters. Here, we discuss the methods for the CANEWS and offer preliminary analyses of 33 months of the CANEWS based on atmospheric deposition data from two sites in RMNP as well as responses from agricultural producers after warnings were issued. Results showed that the CANEWS accurately predicted 6 of 9 high N deposition weeks at a lower-elevation observation site, but only 4 of 11 high N deposition weeks at a higher-elevation site. Sixty agricultural producers from 39 of Colorado’s agricultural operations volunteered for the CANEWS, and a two-way line of communication between agricultural producers and scientists was formed. For each warning issued, an average of 23 producers responded to a postwarning survey. Over 75% of responding CANEWS participants altered their practices after an alert. While the current effort was insufficient to reduce atmospheric deposition, we were encouraged by the collaborative spirit between agricultural, scientific, and resource management communities. Solving a broad and complex social-ecological problem requires both a technological approach, such as the CANEWS, and collaboration and trust from all participants, including agricultural producers, land managers, university researchers, and environmental agencies.

Unfenced plains bison are rare and only occur in a small number of locations throughout Canada and the United States. We examined management guidelines for maintenance of genetic health and population persistence for a small and isolated population of plains bison that occupy the interface between a protected national park and private agricultural lands. To address genetic health concerns, we measured genetic diversity relative to other populations and assessed the potential effects of genetic augmentation. We then used individual-based population viability analyses (PVA) to determine the minimum abundance likely to prevent genetic diversity declines. We assessed this minimum relative to a proposed maximum social carrying capacity related to bison use of human agricultural lands. We also used the PVA to assess the probability of population persistence given the limiting factors of predation, hunting, and disease. Our results indicate that genetic augmentation will likely be required to achieve genetic diversity similar to that of other plains bison populations. We also found that a minimum population of 420 bison yields low probability of additional genetic loss while staying within society-based maxima. Population estimates based on aerial surveys indicated that the population has been below this minimum since 2007. Our PVA simulations indicate that current hunting practices will result in undesirable levels of population extinction risk and further declines in genetic variability. Our study demonstrates that PVA can be used to evaluate potential management scenarios as they relate to long-term genetic conservation and population persistence for rare species.

Accurate characterization of Carbon (C) consequences of forest disturbances and management is critical for informed climate mitigation and adaptation strategies. While research into generalized properties of the forest C cycle informs policy and provides abstract guidance to managers, most management occurs at local scales and relies upon monitoring systems that can consistently provide C cycle assessments that explicitly apply to a defined time and place. We used an inventory-based forest monitoring and simulation tool to quantify C storage effects of actual fires, timber harvests, and forest regeneration conditions in the Greater Yellowstone Ecosystem (GYE). Results show that (1) the 1988 fires had a larger impact on GYE's C storage than harvesting during 1985-2011; (2) continuation of relatively high harvest rates of the region's National Forest land, which declined after 1990, would have shifted the disturbance agent primary importance on those lands from fire to harvest; and (3) accounting for local heterogeneity of post-disturbance regeneration patterns translates into large regional effects on total C storage. Large fires in 1988 released about 8.3 ± 0.3 Mg/ha of C across Yellowstone National Park (YNP, including both disturbed and undisturbed area), compared with total C storage reductions due to harvest of about 2.3 ± 0.3 Mg/ha and 2.6 ± 0.2 Mg/ha in adjacent Caribou-Targhee and Gallatin National Forests, respectively, from 1985-2011. If the high harvest rates observed in 1985-1989 had been maintained through 2011 in GYE National Forests, the C storage effect of harvesting would have quintupled to 10.5 ± 1.0 Mg/ha, exceeding the immediate losses associated with YNP's historic fire but not the longer-term net loss of carbon (16.9 ± 0.8 Mg/ha). Following stand-replacing disturbance such as the 1988 fires, the actual regeneration rate was slower than the default regional average rate assumed by empirically calibrated forest growth models. If regeneration following the 1988 fire had reached regionally average rates, either through different natural circumstances or through more active management, YNP would have had approximately 4.1 Mg/ha more forest carbon by year 2020. This study highlights the relative effects of fire disturbances and management activities on regional C storage, and demonstrates a forest carbon monitoring system that can be both applied consistently across the US and tailored to questions of specific local management interest.

The UNESCO Man and the Biosphere program has operated for 45 years as an international program that started in the 1970s to conserve biotic communities and provide areas for research, education, and training. The program later evolved in the 1990s to address social and environmental issues in a sustainable manner across a landscape. This program was one of the first efforts that recognized the importance of working beyond park and protected area boundaries and the need to sustain livelihoods as much as the resources. In the MAB program's infancy, the United States (U.S.) was a major advocate and leader with more than 45 biosphere reserves, most of them established in or around 1976. Yet, many political, economic, and other external factors influenced the U.S. MAB involvement in subsequent years. Consequently, the U.S. has remained largely inactive in the international MAB network for the past fifteen years until a recent push to revive the program under the leadership of the State Department and the National Park Service. Through in-depth research on two longterm U.S. biosphere reserves, this paper provides a description of the key events impacting the U.S. MAB program over the past several decades and discusses the influential role of politics, a public image, and the perceptions of international designations. Through the lessons presented in this paper, recommendations are provided to support the revival of the MAB program in the U.S.

Community wildlife management programs in African protected areas aim to deliver livelihood and social benefits to local communities in order to bolster support for their conservation objectives. Most of these benefits are delivered at the community level. However, many local people are also seeking more individual or household-level livelihood benefits from community wildlife management programs because it is at this level that many of the costs of protected area conservation are borne. Because community wildlife management delivers few benefits at this level, support for their conservation objectives amongst local people often declines. The study investigated the implications of this for reducing poaching in Serengeti National Park, Tanzania. Three community wildlife management initiatives undertaken by Park management were compared with regard to their capacity to deliver the individual and household-level benefits sought by local people: community conservation services, wildlife management areas and community conservation banks. Interviews were carried out with poachers and local people from four villages in the Western Serengeti including members of village conservation banks, as well as a number of key informants. The results suggest that community conservation banks could, as a complementary strategy to existing community wildlife management programs, potentially provide a more effective means of reducing poaching in African protected areas than community wildlife management programs alone.

Illegal activities and use of park resources are the main challenges facing mountain gorilla (Gorilla beringei beringei) conservation and the protection of their habitats in the East Africa’s Greater Virunga Transboundary Landscape (GVTL). Indigenous residents around GVTL are considered the primary illegal users of park resources. Despite this, there is limited understanding of the current and past perceptions of indigenous residents living in communities adjacent to two GVTL parks; Volcanoes National Park in Rwanda and Mgahinga Gorilla National Park in Uganda. Equally, there is also limited understanding regarding the actual incidences of illegal activities inside both parks. This paper addresses these gaps. Perception data were collected from indigenous residents living adjacent to both parks. Further, Ranger-based Monitoring (RbM) data from both parks were analyzed to determine actual numbers and types of illegal activities over the 9-year period. Interestingly, findings indicated that residents perceived the prevalence of illegal activities to be decreasing across GVTL. To the contrary, RbM findings indicated that the number of actual illegal activities was increasing significantly, particularly in Volcanoes National Park. The discrepancy found between the two perspectives provides for a discussion of the social biases potentially present in these data, and their implications for management. Results also illuminated the subsistence-related nature of most illegal behaviors and suggest that to reduce illegal activities and local dependency on park resources, park management must work with communities and support them in tapping into alternative livelihoods and finding ways to address community household subsistence needs.

Throughout the developing world, mobile phones are spreading rapidly into rural areas where subsistence livelihoods, biodiversity conservation, and human-wildlife conflict (HWC) are each common. Despite this trend, little is known about the relationship between mobile phones and HWC in conservation landscapes. This paper examines this relationship within ethnically Maasai communities in northern Tanzania on the border of Tarangire National Park. Mixed qualitative and quantitative methods of data collection and analysis are used to (1) describe how Maasai agro-pastoralists use phones to manage human-wildlife interactions; and (2) assess the relationship between phone use and measures of HWC, controlling for other factors. The findings indicate that households use phones to reduce the number and severity of HWC events and that the relationship between phones and HWC varies according to the type of HWC.

Public agencies face significant political obstacles when they try to change long-standing policies. This paper examines efforts by the U.S. National Park Service to change long-term policies in Yellowstone and Yosemite national parks. We argue that, to be successful, the agency and pro-change allies must expand the sphere of conflict to engage the support of the broader American public through positive framing, supportive science, compelling economic arguments, consistent goals, and the commitment of other institutional actors. We show that the agency is capable of creating these conditions, as in the reintroduction of wolves to Yellowstone, but we argue that this is not always the outcome, as in reducing automobile congestion in Yosemite Valley.

This research empirically merges together two related theories: the elaboration likelihood model and the theory of planned behavior. A structural equation modeling approach is used to evaluate the relationship between the two theories and their collective impacts on behavioral intentions. The results suggest elaboration predicts the components of the theory of planned behavior (attitudes, subjective norms, and perceived behavior control), which in turn all predicted behavior intentions. Furthermore, results showed that the components of the theory of planned behavior partially meditated the relationship between elaboration and behavioral intentions, indicating that elaboration works mostly through the components of the theory of planned behavior to impact behavioral intentions. This study represents an improved understanding of the influence of communication techniques on visitor behaviors in sustainable tourism settings. Additionally, the discussion exemplifies how these techniques can be used to improve communications and evaluate communication strategies.

Recent advances in fire management led landscape managers to adopt an integrated fire fighting strategy in which fire suppression is supported by prevention actions and by knowledge of local fire history and ecology. In this framework, an accurate evaluation of fire ignition risk and its environmental drivers constitutes a basic step toward the optimization of fire management measures. In this paper, we propose a multivariate method for identifying and spatially portraying fire ignition risk across a complex and heterogeneous landscape such as the National Park of Cilento, Vallo di Diano, and Alburni (southern Italy). The proposed approach consists first in calculating the fire selectivity of several landscape features that are usually related to fire ignition, such as land cover or topography. Next, the fire selectivity values of single landscape features are combined with multivariate segmentation tools. The resulting fire risk map may constitute a valuable tool for optimizing fire prevention strategies and for efficiently allocating fire fighting resources.

Extensive outbreaks of tree-killing insects are increasing across forests in Europe and North America due to climate change and other factors. Yet, little recent research examines visitor response to visual changes in conifer forest recreation settings resulting from forest insect infestations, how visitors weigh trade-offs between physical and social forest environment factors, or how visitor preferences might differ by nationality. This study explored forest visitor preferences with a discrete choice experiment that photographically simulated conifer forest stands with varying levels of bark beetle outbreaks, forest and visitor management practices, and visitor use levels and compositions. On-site surveys were conducted with visitors to State Forest State Park in Colorado (n = 200), Lake Bemidji State Park in Minnesota (n = 228), and Harz National Park in Germany (n = 208). Results revealed that the condition of the immediate forest surrounding was the most important variable influencing visitors' landscape preferences. Visitors preferred healthy mature forest stands and disliked forests with substantial dead wood. The number of visitors was the most important social factor influencing visitor landscape preferences. Differences in the influence of physical and social factors on visual preferences existed between study sites. Findings suggest that both visual forest conditions and visitor use management are important concerns in addressing landscape preferences for beetle-impacted forest recreation areas.

Transportation infrastructure in national parks has historically been designed for the automobile. With more vehicles in the parks, visitors found themselves in circumstances more reminiscent of a city than a park. Traffic jams, overcrowding, illegal parking, horn honking, and idling vehicles became common, creating stress and contributing to air and noise pollution, the very things visitors were hoping to get away from. Park managers began searching for alternatives, including shuttle systems. Many national parks have implemented optional shuttle systems, but relatively few have completely closed roads to vehicles, transporting visitors on mandatory shuttles. Zion National Park instituted a mandatory shuttle system in May 2000 to relieve crowding and congestion in the main canyon and to protect natural resources. Taking a longitudinal approach, attributes of the shuttle (e.g., crowding, accessibility, freedom, efficiency, preference, and success) were assessed with experiential park factors (e.g., scenic beauty, naturalness, solitude, tranquility, air quality, and soundscape) in 2000, 2003, and 2010 by surveying shuttle-riding park visitors. While visitors initially reported a few reservations about the shuttle system, by 2003, the majority rated the system successful. Ratings of all shuttle-related variables, except crowding, improved over the decade. Improvements were greatest for freedom, accessibility, and efficiency. Multiple regression found overall shuttle success to be mediated by preference, freedom, accessibility, efficiency, and comfort. Experiential variables assessing park conditions followed a similar pattern, with improved ratings as the decade progressed. Results provide important insights into the visitor experience with mandatory alternative shuttle systems in national parks.

Understanding perceptions of global environmental issues, such as climate change, can help inform resource management, policy development, and communication with constituents. Although a considerable amount of research documents citizens' perceptions of climate change, few have investigated how interactions with climate-impacted parks and protected areas influence these perceptions, and consequently elements of environmental management. Using a mixed methods Instrument Development Approach, the researchers examined the stability of park visitors' (N = 429) climate change perceptions during a daylong interaction with climate-sensitive and influenced resources at Kenai Fjords National Park in Alaska. Results indicate that global-level beliefs about climate change remained relatively stable during a park experience, but perceptions about climate change at the park-level (e.g., impacts) appeared more malleable. Findings also revealed the type of park experience (terrestrial vs. marine) can influence the degree of change in visitors' perceptions. Implications for communication, outreach, and park management are discussed.

Yellowstone National Park visitor data were obtained from a survey collected for the National Park Service by the Park Studies Unit at the University of Idaho. Travel cost models have been conducted for national parks in the United States; however, this study builds on these studies and investigates how benefits vary by types of visitors who participate in different activities while at the park. Visitor clusters were developed based on activities in which a visitor participated while at the park. The clusters were analyzed and then incorporated into a travel cost model to determine the economic value (consumer surplus) that the different visitor groups received from visiting the park. The model was estimated using a zero-truncated negative binomial regression corrected for endogenous stratification. The travel cost price variable was estimated using both 1/3 and 1/4 the wage rate to test for sensitivity to opportunity cost specification. The average benefit across all visitor cluster groups was estimated at between $235 and $276 per person per trip. However, per trip benefits varied substantially across clusters; from $90 to $103 for the "value picnickers," to $185-$263 for the "backcountry enthusiasts," $189-$278 for the "do it all adventurists," $204-$303 for the "windshield tourists," and $323-$714 for the "creature comfort" cluster group.

There is a close relationship between ports and reef areas, mainly because reefs provide protection to vessels against extreme weather events like storms and hurricanes. This historical relationship has generated severe impacts on reef ecosystems. In order to identify the main impacts from the construction of port facilities in shallow coral reef areas, we analyzed and described the effects of land reclamation and coastal structure construction associated to port growth throughout a century in the Sistema Arrecifal Veracruzano National Park, Mexico. We used aerial photographs and maps of the nineteenth and early twentieth century to assess the impacts caused by port expansion activities on shallow coral reefs. Three types of impacts were identified: (a) direct reef area loss caused by landfills and perpendicular coastal structures construction leading to the loss of nearly 50 % of the fringing reef near to the port; (b) fragmentation in short- and medium-term scale, which affects two fringing reefs, and (c) long-term modification of coastal dynamics leading to sedimentation and loss of a complete reef area. On the eve of a new expansion of Veracruz Port, we used the New Port Project Plan, long-shore net drift geomorphic indicators and the port impact typology from the 100-year period assessment to evaluate a possible future scenario. The scenario describes how the new expansion project will repeat the three types of impacts affecting a whole reef area, which is currently part of the National Park.

Trail settings in national parks are essential management tools for improving both ecological conservation efforts and the quality of visitor experiences. This study proposes a plan for the appropriate maintenance of trails in Chubusangaku National Park, Japan, based on the recreation opportunity spectrum (ROS) approach. First, we distributed 452 questionnaires to determine park visitors' preferences for setting a trail (response rate = 68 %). Respondents' preferences were then evaluated according to the following seven parameters: access, remoteness, naturalness, facilities and site management, social encounters, visitor impact, and visitor management. Using nonmetric multidimensional scaling and cluster analysis, the visitors were classified into seven groups. Last, we classified the actual trails according to the visitor questionnaire criteria to examine the discrepancy between visitors' preferences and actual trail settings. The actual trail classification indicated that while most developed trails were located in accessible places, primitive trails were located in remote areas. However, interestingly, two visitor groups seemed to prefer a well-conserved natural environment and, simultaneously, easily accessible trails. This finding does not correspond to a premise of the ROS approach, which supposes that primitive trails should be located in remote areas without ready access. Based on this study's results, we propose that creating trails, which afford visitors the opportunity to experience a well-conserved natural environment in accessible areas is a useful means to provide visitors with diverse recreation opportunities. The process of data collection and analysis in this study can be one approach to produce ROS maps for providing visitors with recreational opportunities of greater diversity and higher quality., Article, ENVIRONMENTAL MANAGEMENT. 51(6):1126-1136 (2013)

Ecological impacts associated with nature-based recreation and tourism can compromise park and protected area goals if left unrestricted. Protected area agencies are increasingly incorporating indicator-based management frameworks into their management plans to address visitor impacts. Development of indicators requires empirical evaluation of indicator measures and examining their ecological and social relevance. This study addresses the development of the informal trail indicator in Yosemite National Park by spatially characterizing visitor use in open landscapes and integrating use patterns with informal trail condition data to examine their spatial association. Informal trail and visitor use data were collected concurrently during July and August of 2011 in three, high-use meadows of Yosemite Valley. Visitor use was clustered at statistically significant levels in all three study meadows. Spatial data integration found no statistically significant differences between use patterns and trail condition class. However, statistically significant differences were found between the distance visitors were observed from informal trails and visitor activity type with active activities occurring closer to trail corridors. Gender was also found to be significant with male visitors observed further from trail corridors. Results highlight the utility of integrated spatial analysis in supporting indicator-based monitoring and informing management of open landscapes. Additional variables for future analysis and methodological improvements are discussed.

The popularity of ecotourism in the marine protected areas of Mexico has increased over the last 10 years; in particular there is a large development of a SCUBA diving industry in the Mexican Pacific including Isabel Island. Given the risks associated with human activity in the marine environments around this island, we propose two ecotourism management strategies: (1) the creation and use of underwater trails, and (2) the estimation of the specific tourism carrying capacity (TCC) for each trail. Six underwater trails were selected in sites that presented elements of biological, geological, and scenic interest, using information obtained during field observations. The methodology used to estimate the TCC was based upon the physical and biological conditions of each site, the infrastructure and equipment available, and the characteristics of the service providers and the administrators of the park. Correction factors of the TCC included elements of the quality of the visit and the threat and vulnerability of the marine environment of each trail (e.g., divers' expertise, size and distance between groups of divers, accessibility, wind, coral coverage). The TCC values ranged between 1,252 and 1,642 dives/year/trail, with a total of 8,597 dives/year for all six trails. Although these numbers are higher than the actual number of recreational visitors to the island (~1,000 dives per year), there is a need for adequate preventive management if the diving sites are to maintain their esthetic appeal and biological characteristics. Such management might be initially directed toward using only the sites and the TCC proposed here.

We investigated how visitor-use affects water quality in wilderness in Yosemite National Park. During the summers of 2012-2014, we collected and analyzed surface-water samples for water-quality indicators, including fecal indicator bacteria Escherichia coli, nutrients (nitrogen, phosphorus, carbon), suspended sediment concentration, pharmaceuticals, and hormones. Samples were collected upstream and downstream from different types of visitor use at weekly to biweekly intervals and during summer storms. We conducted a park-wide synoptic sampling campaign during summer 2014, and sampled upstream and downstream from meadows to evaluate the mitigating effect of meadows on water quality. At pack stock stream crossings, Escherichia coli concentrations were greater downstream from crossings than upstream (median downstream increase in Escherichia coli of three colony forming units 100 mL-1), with the greatest increases occurring during storms (median downstream increase in Escherichia coli of 32 CFU 100 mL-1). At backpacker use sites, hormones, and pharmaceuticals (e.g., insect repellent) were detected at downstream sites, and Escherichia coli concentrations were greater at downstream sites (median downstream increase in Escherichia coli of 1 CFU 100 mL-1). Differences in water quality downstream vs. upstream from meadows grazed by pack stock were not detectable for most water-quality indicators, however, Escherichia coli concentrations decreased downstream, suggesting entrapment and die-off of fecal indicator bacteria in meadows. Our results indicate that under current-use levels pack stock trail use and backpacker use are associated with detectable, but relatively minor, effects on water quality, which are most pronounced during storms.

Climate change effects are noticeably evident above the timberline where glacier and permafrost processes and mass movements drive the surface evolution. In particular, the cryosphere shrinkage is deeply changing the features and characteristics of several glacierized mountain areas of the world, and these modifications can also affect the landscape perception of tourists and mountaineers. On the one hand glacier retreat is increasing the interest of tourists and visitors in areas witnessing clear climate change impacts; on the other hand cryosphere shrinkage can impact the touristic appeal of mountain territories which, diminishing their ice and snow coverage, are also losing part of their aesthetic value. Then, to promote glacierized areas in a changing climate and to prepare exhaustive and actual proposals for sustainable tourism, it is important to deepen our knowledge about landscape perception of tourists and mountaineers and their awareness of the ongoing environmental modifications. Here we present the results from a pilot study we performed in summer 2009 on a representative glacierized area of the Alps, the Forni Valley (Stelvio National Park, Lombardy, Italy), a valley shaped by Forni, the largest Italian valley glacier. During the 2009 summer season we asked tourists visiting the Forni Valley to complete a questionnaire. This study was aimed at both describing the features and characteristics of tourists and mountaineers visiting this Alpine zone in summer and evaluating their landscape perception and their ability to recognize climate change impacts and evidence. Our results suggest that the dissemination strategies in a natural protected area have to take into account not only the main landscape features but also the sites where the information will be given. In particular considering the peculiarities of the huts located in the area, such as their different accessibility and the fact that they are included or not in a mountaineering network like that of the Italian Alpine Club. Both these factors can influence the kind of visitors to the area, thus requiring different dissemination strategies. Moreover, differences in the viewpoints from where visitors could watch and understand landscape also have to be considered. Next, in a protected area where climate change effects are evident, the dissemination strategies should be developed in close cooperation with scientists who are analyzing the area and with the support of periodic interviews which could be very useful to evaluate the effectiveness of the applied dissemination methods. Last but not least, the questionnaire should be standardized and distributed in several protected areas, thus permitting useful comparisons and the identification of common solutions for sharing in a friendly way scientific knowledge about climate change and its effects on the environment and the landscape.

Research on recreational place attachment suggests that place identity, or the emotional/symbolic ties people have to places, and place dependence, which describes a functional attachment to a specific place, influence the perception of social and environmental site conditions. Recent research, however, has found that place attachment is not always a predictor of such perceptions. This study investigated the influence of place attachment and experience use history on the perception of depreciative visitor behavior, recreation impacts and crowding in an urban national park. In 2006, 605 on-site visitors to the heavily-used Viennese part of the Danube Floodplains National Park were asked about past experience, place attachment, perceptions of depreciative visitor behavior, crowding, changes in visitor numbers during the past ten years, and recreation impacts on wildlife. Confirmatory factor analysis confirmed the two dimensions of place attachment. Linear regression analyses found that place identity and place dependence were related to some perceived depreciative visitor behaviors and visitor number changes but not to crowding, while experience use history additionally related to perceived crowding. Visitors with higher place attachment and past experience were more sensitive to social and environmental site conditions. Management implications of the findings are discussed.

Recent appearance of cattail (Typha domingensis) within a southern Everglades slough-Upper Taylor Slough (Everglades National Park)-suggests ecosystem eutrophication. We analyze water quality, nutrient enrichment, and water management operations as potential drivers of eutrophication in Upper Taylor Slough. Further, we attempt to determine why surface water phosphorus, a parameter used commonly to monitor ecosystem health in the Everglades, did not serve as an early warning for eutrophication, which has broader implication for other restoration efforts. We found that surface water total phosphorus concentrations generally were below a 0.01 mg L(-1) threshold determined to cause imbalances in flora and fauna, suggesting no ecosystem eutrophication. However, assessment of nutrient loads and loading rates suggest Upper Taylor Slough has experienced eutrophication and that continued total phosphorus loading through a point-source discharge was a major driver. These nutrient loads, combined with increases in hydroperiods, led to the expansion of cattail in Upper Taylor Slough. We recommend other metrics, such as nutrient loads, periphyton and arthropod community shifts, and sediment core analyses, for assessing ecosystem health. Monitoring surface water alone is not enough to indicate ecosystem stress.

Nitrogen (N) is a major control on primary productivity and hence on the productivity and diversity of secondary producers and consumers. As such, ecosystem structure and function cannot be understood without a comprehensive understanding of N cycling and dynamics. This overview describes the factors that govern N distribution and dynamics and the consequences that variable N dynamics have for structure, function and thresholds of potential concern (TPCs) for management of a semiarid southern African savanna. We focus on the Kruger National Park (KNP), a relatively intact savanna, noted for its wide array of animal and plant species and a prized tourist destination. KNP's large size ensures integrity of most ecosystem processes and much can be learned about drivers of ecosystem structure and function using this park as a baseline. Our overview shows that large scale variability in substrates exists, but do not necessarily have predictable consequences for N cycling. The impact of major drivers such as fire is complex; at a landscape scale little differences in stocks and cycling were found, though at a smaller scale changes in woody cover can lead to concomitant changes in total N. Contrasting impacts of browsers and grazers on N turnover has been recorded. Due to the complexity of this ecosystem, we conclude that it will be complicated to draw up TPCs for most transformations and pools involved with the N cycle. However, we highlight in which cases the development of TPCs will be possible.

The Jamaica Bay portion of Gateway National Recreation Area, located next to highly urbanized New York City, faces many challenges to preserve and protect its natural, cultural, and recreational resources. To aid in the management of the park resources, detailed estuarine shoreline analyses of Jamaica Bay were undertaken using imagery taken in 1951, 1974, and 2006. A 15-class land use/land cover (LULC) classification scheme was created after doing an initial examination of the types of LULC in the 2006 orthoimagery and then applied in the analyses of the previous years. By quantifying how and where the shoreline has changed over the past 60 years, park managers can better assess the impact of management practices by comparing LULC of the shoreline within the park boundary to the LULC of the shoreline outside the park boundary before and after the park was created in 1972. Despite the heavy development of New York City and the trend for shoreline modification, the overall shoreline of Jamaica Bay has maintained large percentages of undeveloped vegetation and sandy beaches. Much of the LULC change has occurred in the creeks as a result of dredging and shape modification for residential and commercial uses. Park management has been effective in limiting the alteration of undeveloped shoreline although there have been significant changes in the relative percentages of sand and vegetated beaches between 1974 and 2006.

Understanding interactions between large ships and large whales is important to estimate risks posed to whales by ships. The coastal waters of Alaska are a summer feeding area for humpback whales (Megaptera novaeangliae) as well as a prominent destination for large cruise ships. Lethal collisions between cruise ships and humpback whales have occurred throughout Alaska, including in Glacier Bay National Park (GBNP). Although the National Park Service (NPS) establishes quotas and operating requirements for cruise ships within GBNP in part to minimize ship–whale collisions, no study has quantified ship–whale interactions in the park or in state waters where ship traffic is unregulated. In 2008 and 2009, an observer was placed on ships during 49 different cruises that included entry into GBNP to record distance and bearing of whales that surfaced within 1 km of the ship’s bow. A relative coordinate system was developed in ArcGIS to model the frequency of whale surface events using kernel density. A total of 514 whale surface events were recorded. Although ship–whale interactions were common within GBNP, whales frequently surfaced in front of the bow in waters immediately adjacent to the park (west Icy Strait) where cruise ship traffic is not regulated by the NPS. When ships transited at speeds >13 knots, whales frequently surfaced closer to the ship’s midline and ship’s bow in contrast to speeds slower than 13 knots. Our findings confirm that ship speed is an effective mitigation measure for protecting whales and should be applied to other areas where ship–whale interactions are common.

Exploitation of certain resources within a protected area on a sustainable basis could contribute to higher living standards of rural people, particularly those in poor countries, and decrease conflicts between these populations and park authorities. This article presents data from a case study of Kopaonik National Park (NP), Serbia, which is a park with natural resources, most notably bilberries, which have always been relied on by local people. Vaccinium myrtillus traditionally has been collected for decades in Kopaonik NP and used by local people. However, little is known about the socioeconomic and ecological relations that affect the collection and use of this species. The aim of the present study was to understand how local people collect bilberries in Kopaonik NP and what their attitudes toward the park are. Household questionnaire data were used to examine how local people collect bilberries and how to improve the relations between local people and NP authorities. The survey questionnaire included 52 households from 7 local communities, and we applied a purposive sampling strategy. In addition, expert interviews were conducted, and from these data we obtained a broader understanding of the relation between local people and NP authorities. The results indicate that in Kopaonik NP, there is a conflict between pickers and NP authorities. Sustainable management should be directed toward the protection of bilberries. Education of local people is a key element in the sustainable collection and protection of natural resources.

Hunting is a threat to wildlife within the Hkakaborazi National Park in north Myanmar. We used questionnaire surveys to obtain data on variables such as commonly targeted species, prices of traded wildlife, reasons for hunting and the relative importance of livelihood sources. We examine (a) the significance of hunting and trade for livelihoods and explore (b) the impacts of hunting on targeted species. Ninety per cent of trade records (n = 803) was constituted by seven species commonly targeted by hunters (serow, red goral, muntjac, bear, Assamese macaque, black musk deer and takin). Commercially valuable species previously targeted by hunters (tiger, otter, pangolin) appear to be completely absent from current harvest records and potentially in decline. Although farming is the predominant occupation, hunting (driven by trade) represents a significantly higher source of income than other livelihood activities. Management recommendations include increased investment in enforcement, education and outreach, small livestock development, improved crop productivity, demarcation of no-take areas for wildlife and biological monitoring of targeted species.

This article examines one MPA--the Gulf of Mannar National Park and Biosphere Reserve--located in southern India, and four types of social conflict that have surrounded its establishment. Taking the strength of wellbeing aspirations as point of departure, we focus on two themes: the implications of MPA embeddedness in wider societal systems, and the consequences of natural and social variety for governance. We conclude first of all that conflict resolution depends on MPA authorities' willingness to engage with the interferences that emerge from outside the MPA area. Secondly, we point out the varying wellbeing aspirations of the population and the need to develop governance partnerships. The latter are argued to contribute to more balanced decision making, as well as to a greater appreciation among the target population of the 'fairness' of MPA policy.

Informal trails created or perpetuated by visitors is a management challenge in many protected natural areas such as Yosemite National Park. This is a significant issue as informal trail networks penetrate and proliferate into protected landscapes and habitats, threatening ecological integrity, aesthetics, and visitor experiences. In order to develop effective strategies for addressing this problem under an adaptive management framework, indicators must be developed and monitoring protocol must be established to gather timely and relevant data about the condition, extent, and distribution of these undesired trail segments. This article illustrates a process of developing and evaluating informal trail indicators for meadows in Yosemite Valley. Indicator measures developed in past research were reviewed to identify their appropriateness for the current application. Information gaps in existing indicator measures were addressed by creating two new indices to quantify the degree of informal trailing based on its land fragmentation effects. The selected indicator measures were applied to monitoring data collected between 2006 and 2008. The selected measures and indices were evaluated for their ability to characterize informal trail impacts at site and landscape scales. Results demonstrate the utility of indicator measures in capturing different characteristics of the informal trail problem, though several metrics are strongly related to each other. The two fragmentation indices were able to depict fragmentation without being too sensitive to changes in one constituent parameter. This study points to the need for a multiparameter approach to informal trail monitoring and integration with other monitoring data. Implications for monitoring programs and research are discussed.

Like many governmental actors in recent decades, the U.S. National Park Service (NPS) has operated increasingly through partnerships with other state and federal agencies, non-governmental organizations (NGOs), community groups, and private sector corporations. Perhaps the most salient example of this trend toward partnerships is the rapid growth and development of national heritage areas (NHAs). Since the first NHA received congressional designation in 1984, NHAs have become an increasingly popular strategy for protecting and managing landscapes. To date, congressional designation has been granted to 49 NHAs, making them one of the fastest growing initiatives involving the NPS. Despite this growth, no prior research has examined the efficacy or effectiveness of the NHA model. This article introduces the NHA concept, while reviewing the literature on evaluation research and its application to protected area management. We then offer an NHA program theory model for evaluating NHAs. The model was developed using a theory-based, process evaluation approach, along with 90 qualitative interviews conducted at three study sites: Blackstone River Valley National Heritage Corridor, MA-RI (BLAC); Delaware and Lehigh National Heritage Corridor, PA (DELE); and Cane River National Heritage Area, LA (CANE). We conclude by discussing the key challenges and implications associated with developing a long-term research agenda for evaluating NHAs.

National parks have long endured controversy concerning their fundamental purpose. Is their purpose to conserve natural resources and scenery? Provide for the use and enjoyment of people? Or balance conservation with use and enjoyment? Most people involved in the controversy have taken a view that supports one of the three purposes above. In this article, I contend that the fundamental mandate for parks is conservation of natural resources and scenery but that the mandate is "weak" both as a matter of law as well as because of other factors that weaken it.

A contingent valuation study was conducted with adult Kenyan citizens and foreign tourists to estimate the value of recreational benefits arising from coral reefs at Mombasa Marine National Park and Reserve (MMNPR), and to assess the implications for local reef management. Citizen and foreign visitors to MMNPR were willing to pay an extra $2.2 (median = $1.6) and $8 (median = $6.7) per visit respectively, in addition to current park entrance fees, to support reef quality improvements. By aggregating visitors' willingness to pay bids over the number of visitors to MMNPR in 2006-2007 the value of benefits was estimated at $346,733, which was more than twice the total annual operational expenditure of $152,383 for MMNPR. The findings indicate that annual revenues from citizen and foreign visitors may be increased by 60% to $261,932 through the implementation of proposed higher park fees of $3.10 for citizens and $15 for foreign visitors. However, any fee increase would serve to intensify concerns among citizens that only relatively affluent Kenyans can afford to visit MMNPR. Park managers need to demonstrate that the extra revenue would be used to fund the proposed conservation activities. This valuation study demonstrates that visitors are prepared to pay higher user fees for access to the marine protected area revealing considerable untapped resource to finance reef quality improvements.

The administration of Jiuzhaigou National Park in Sichuan Province, China, is in the process of considering a range of upgrades to their sanitation and wastewater treatment systems. Their case history involves an ongoing series of engineering design flaws and management failures. The administration of the Park identified sustainability, environmental protection, and education goals for their sanitation and wastewater treatment system. To meet the goal of sustainability, environmental and economic concerns of the Park's administration had to be balanced with socio-cultural needs. An advanced reconnaissance method was developed that identified reasons for previous failures, conducted stakeholder analysis and interviews, determined evaluation criteria, and introduced innovative alternatives with records of successful global implementations. This evaluation also helped the Park to better define their goals. To prevent future failures, the administration of the Park must commit to a balanced and thorough evaluation process for selection of a final alternative and institute effective long-term management and monitoring of systems. In addition, to meet goals and achieve energy efficient, cost-effective use of resources, the Park must shift their thinking from one of waste disposal to resource recovery. The method and criteria developed for this case study provides a framework to aid in the successful implementation of sanitation projects in both underdeveloped and developed areas of the world, incorporating socio-cultural values and resource recovery for a complex group of stakeholders.
