Human activity affects plant and animal populations across local to global scales, and the management of recreation areas often aims to reduce such impacts. Specifically, by understanding patterns of human activity and its influence on animal populations, parks and recreation areas can be managed to provide spatial and temporal refuge to wildlife most sensitive to this type of human disturbance. However, additional research is necessary to understand how human activity influences wildlife populations, habitat use, and activity patterns for a diversity of wildlife species. We studied the potential impacts of human activity (as measured by nonmotorized recreationists) on populations and activity patterns of 12 mammal species, including herbivores and carnivores, from 63 motion‐activated cameras that sampled game trails and human trails with varying degrees of human activity along the Front Range of Colorado. Human activity was greatest during the day and minimal or absent during the night. All wildlife species in our study used human trails, although the extent to which human recreation altered the occupancy, relative habitat use, and activity patterns of wildlife varied across species, where some animals appeared to be more influenced by human activity than others. Some species (e.g., fox squirrel, red fox, and striped skunk) did not demonstrate a response to human activity. Other species (e.g., black bear, coyote, and mule deer) altered their activity patterns on recreation trails to be more active at night. Across all wildlife, the degree to which animals altered activity patterns on human trails was related to their natural activity patterns and how active they were during the day when human activity was greatest; species that exhibited greater overlap in natural activity patterns with humans demonstrated the greatest shifts in their activity, often exhibiting increased nocturnal activity. Further, some species (e.g., Abert’s squirrel, bobcat, and mountain lion) exhibited reduced occupancy and/or habitat use in response to human recreation. Managing spatial and temporal refuges for wildlife would likely reduce the impacts of human recreation on animals that use habitat in proximity to trail networks.

The temperate grasslands of North America remain one of the most modified and threatened ecosystems on the planet. In the United States, the conservation of grassland-dependent wildlife continues to be challenged by the widespread conversion of privately owned grasslands to cropland. Recent analyses indicate that land exiting the Conservation Reserve Program (CRP), the country's largest private lands conservation program, is a primary source of grassland conversion. In this mixed-methods study, we employed focus groups and mail surveys to understand the decisions made by landowners in the southern Great Plains as their CRP contracts near expiration and up to 7 years following expiration. We explored both the post-contract intentions of landowners with fields currently enrolled in CRP and the self-reported, post-contract decisions of landowners whose CRP contracts expired between 2011 and 2017. Interest in re-enrolling in CRP upon contract expiration was high among landowners with current fields; however, over half of landowners with former CRP fields reported being unable to re-enroll when they tried. We found higher rates of grassland persistence than have been previously reported, but also detected temporal patterns that suggest that cropland reversion is increasingly likely as the time since contract expiration increases. This study highlights the need for increased attention to the barriers that preclude transition into other conservation programs following CRP and more detailed understanding of what drives landowner decision-making about re-enrollment and post-CRP land use. These insights will be critical for increasing the effectiveness of programs for enduring grassland conservation on private lands.

Many conservation conflicts are scientifically complex yet are rooted in value conflicts, which result in an impasse. Additional biological information alone is insufficient to resolve this type of conflict. Conceptual models that articulate the material aspects of a system are increasingly used to identify areas where parties disagree. Yet, modeling processes typically follow the conveners’ rules for discussing and assessing the topic, which can exacerbate conflict. Researchers have identified a need for processes that require participants to reflect on the limits of their own philosophical assumptions and acknowledge other perspectives. Cultural models are a promising tool for this purpose because they include nonmaterial beliefs, morals, and values that guide people's understanding of how to interact with an issue, sometimes subconsciously. We explored how cultural models used with conceptual models can improve understanding of value conflicts and used outdoor cat management as a case study. We conducted interviews and focus group discussions with wildlife conservation and cat welfare professionals involved in outdoor cat policy discussions in Hawaii and Washington, D.C. From these conversations, we developed a conceptual model of the outdoor cat management system and cultural models that led stakeholders to weigh elements of the conceptual model differently. Although wildlife conservation professionals generally spoke about outdoor cats as invasive species, cat welfare professionals spoke about them as homeless pets. These conflicting conceptualizations of what an outdoor cat is may help explain the root of many long‐standing disagreements. Examining how and when stakeholders invoke different cultural models allowed us to identify management actions that work with, rather than challenge, those models. Dialogue that embraces conflicting cultural models can be difficult and uncomfortable, but has great potential to overcome conservation impasse and achieve lasting conservation results., Article impact statement: Understanding unstated yet conflicting cultural models of cats as invasive species versus homeless pets can transform conservation conflicts.

Free-ranging domestic cats (Felis catus) incur and impose risks on ecosystems and represent a complex issue of critical importance to biodiversity conservation and cat and human health globally. Prior social science research on this topic is limited and has emphasized feral cats even though owned cats often comprise a large proportion of the outdoor cat population, particularly in urban areas. To address this gap, we examined public risk perceptions and attitudes toward outdoor pet cats across varying levels of urbanization, including along the wildland-urban interface, in Colorado (U.S.A.), through a mail survey of 1397 residents. Residents did not view all types of risks uniformly. They viewed risks of cat predation on wildlife and carnivore predation on cats as more likely than disease-related risks. Additionally, risk perceptions were related to attitudes, prior experiences with cats and cat-wildlife interactions, and cat-owner behavior. Our findings suggest that changes in risk perceptions may result in behavior change. Therefore, knowledge of cat-related risk perceptions and attitudes could be used to develop communication programs aimed at promoting risk-aversive behaviors among cat owners and cat-management strategies that are acceptable to the public and that directly advance the conservation of native species.

Carrying behavior is exhibited for myriad purposes by a variety of animals, including mammalian carnivores, but it has been poorly studied. We used wildlife camera data to document and describe carrying behavior in a suite of native and domestic mammalian carnivores in Colorado, USA. Our objectives were to estimate the carrying rate for each carnivore species, assess the relationship between carrying rate and carnivore body mass, compare items carried to known diets and with proximity to urbanization, and explore seasonal variation in carrying rate. We documented carrying behavior in red foxes (Vulpes vulpes), coyotes (Canis latrans), bobcats (Lynx rufus), gray foxes (Urocyon cinereoargenteus), pumas (Puma concolor), and domestic cats (Felis catus). These carnivores carried objects at relatively low rates (range 0.44%–3.40%), although smaller-bodied carnivores carried items at greater rates than larger-bodied species. Prey items recorded by remote cameras were consistent with vertebrates known to be consumed by each species, and anthropogenic and synanthropic items were more common near the wildland-urban interface. For red fox, the species with the largest sample of carrying events, the rate of carrying varied by season, with increased rates during spring and summer months. Systematic exploration of carrying behavior has the potential to lend insight into carnivore diet in space and time and into shifts in dietary patterns along the wildland-urban interface. We demonstrate the power of camera trap data to examine these relationships and encourage further research of carrying behavior.

Author(s): Gramza, Ashley; Teel, Tara L.; Crooks, Kevin R. | Abstract: Recently, there has been growing interest in the study of the biology of free-ranging cats and their effects on wildlife, generating new estimates of cat densities and predation rates. Although such biological data are important to consider when formulating management strategies, they have done little to stifle conflict between stakeholder groups or reduce the number of cats on the landscape and their ecological impacts. In many cases, this research has actually rekindled debate, often pitting wildlife biologists against animal welfare organizations and the general public. While some social science research regarding human perceptions of free-ranging cats exists, these studies are often initiated after conflict has occurred or after a controversial management strategy has been implemented. Furthermore, few studies have focused on the perceptions of owned free-ranging cats, although these cats may comprise a large proportion of cats on the landscape. The most effective, humane, and socially-acceptable management strategies will involve front-end integration of both social and biological science information as well as inclusion of diverse stakeholders. Our ongoing research provides a framework that wildlife managers, pest managers, animal protection organizations, and local government entities can use to develop socially-relevant and biologically-effective management programs for owned free-ranging domestic cats. This framework involves social science research methods grounded in social psychological theories to help predict human thought and behavior, as well as biological methods to assess cat impacts. Lastly, using our own research as a model, our framework compiles guiding principles that help managers develop effective communication programs aimed at promoting conservation-relevant behaviors.
