Abstract

Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree communities? (2) Which ecological and anthropogenic factors predict these patterns? And (3) what is the extinction risk of locally dominant and rare tree species? Location Global. Time period 1990–2017. Major taxa studied Trees. Methods We used 1.2 million forest plots and quantified local tree dominance as the relative plot basal area of the single most dominant species and local rarity as the percentage of species that contribute together to the least 10% of plot basal area. We mapped global community dominance and rarity using machine learning models and evaluated the ecological and anthropogenic predictors with linear models. Extinction risk, for example threatened status, of geographically widespread dominant and rare species was evaluated. Results Community dominance and rarity show contrasting latitudinal trends, with boreal forests having high levels of dominance and tropical forests having high levels of rarity. Increasing annual precipitation reduces community dominance, probably because precipitation is related to an increase in tree density and richness. Additionally, stand age is positively related to community dominance, due to stem diameter increase of the most dominant species. Surprisingly, we find that locally dominant and rare species, which are geographically widespread in our data, have an equally high rate of elevated extinction due to declining populations through large-scale land degradation. Main conclusions By linking patterns and predictors of community dominance and rarity to extinction risk, our results suggest tha

Abstract

The emergence of alternative stable states in forest systems has significant implications for the functioning and structure of the terrestrial biosphere, yet empirical evidence remains scarce. Here, we combine global forest biodiversity observations and simulations to test for alternative stable states in the presence of evergreen and deciduous forest types. We reveal a bimodal distribution of forest leaf types across temperate regions of the Northern Hemisphere that cannot be explained by the environment alone, suggesting signatures of alternative forest states. Moreover, we empirically demonstrate the existence of positive feedbacks in tree growth, recruitment and mortality, with trees having 4–43% higher growth rates, 14–17% higher survival rates and 4–7 times higher recruitment rates when they are surrounded by trees of their own leaf type. Simulations show that the observed positive feedbacks are necessary and sufficient to generate alternative forest states, which also lead to dependency on history (hysteresis) during ecosystem transition from evergreen to deciduous forests and vice versa. We identify hotspots of bistable forest types in evergreen-deciduous ecotones, which are likely driven by soil-related positive feedbacks. These findings are integral to predicting the distribution of forest biomes, and aid to our understanding of biodiversity, carbon turnover, and terrestrial climate feedbacks.

Abstract

Understanding what controls global leaf type variation in trees is crucial for comprehending their role in terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our understanding of the factors influencing forest leaf types remains incomplete, leaving us uncertain about the global proportions of needle-leaved, broadleaved, evergreen and deciduous trees. To address these gaps, we conducted a global, ground-sourced assessment of forest leaf-type variation by integrating forest inventory data with comprehensive leaf form (broadleaf vs needle-leaf) and habit (evergreen vs deciduous) records. We found that global variation in leaf habit is primarily driven by isothermality and soil characteristics, while leaf form is predominantly driven by temperature. Given these relationships, we estimate that 38% of global tree individuals are needle-leaved evergreen, 29% are broadleaved evergreen, 27% are broadleaved deciduous and 5% are needle-leaved deciduous. The aboveground biomass distribution among these tree types is approximately 21% (126.4 Gt), 54% (335.7 Gt), 22% (136.2 Gt) and 3% (18.7 Gt), respectively. We further project that, depending on future emissions pathways, 17-34% of forested areas will experience climate conditions by the end of the century that currently support a different forest type, highlighting the intensification of climatic stress on existing forests. By quantifying the distribution of tree leaf types and their corresponding biomass, and identifying regions where climate change will exert greatest pressure on current leaf types, our results can help improve predictions of future terrestrial ecosystem functioning and carbon cycling.

Abstract

Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land use and climate have considerably reduced the scale of this system1. Remote-sensing estimates to quantify carbon losses from global forests2–5 are characterized by considerable uncertainty and we lack a comprehensive ground-sourced evaluation to benchmark these estimates. Here we combine several ground-sourced6 and satellite-derived approaches2,7,8 to evaluate the scale of the global forest carbon potential outside agricultural and urban lands. Despite regional variation, the predictions demonstrated remarkable consistency at a global scale, with only a 12% difference between the ground-sourced and satellite-derived estimates. At present, global forest carbon storage is markedly under the natural potential, with a total deficit of 226 Gt (model range = 151–363 Gt) in areas with low human footprint. Most (61%, 139 Gt C) of this potential is in areas with existing forests, in which ecosystem protection can allow forests to recover to maturity. The remaining 39% (87 Gt C) of potential lies in regions in which forests have been removed or fragmented. Although forests cannot be a substitute for emissions reductions, our results support the idea2,3,9 that the conservation, restoration and sustainable management of diverse forests offer valuable contributions to meeting global climate and biodiversity targets.

Abstract

The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain LDG, but rigorous tests of the drivers of LDGs have been limited by a lack of high-quality global species richness data. Here we produce a high-resolution (0.025° × 0.025°) map of local tree species richness using a global forest inventory database with individual tree information and local biophysical characteristics from ~1.3 million sample plots. We then quantify drivers of local tree species richness patterns across latitudes. Generally, annual mean temperature was a dominant predictor of tree species richness, which is most consistent with the metabolic theory of biodiversity (MTB). However, MTB underestimated LDG in the tropics, where high species richness was also moderated by topographic, soil and anthropogenic factors operating at local scales. Given that local landscape variables operate synergistically with bioclimatic factors in shaping the global LDG pattern, we suggest that MTB be extended to account for co-limitation by subordinate drivers. © 2022, The Author(s), under exclusive licence to Springer Nature Limited.

Abstract

One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges and taxonomic difficulties connected to the species concept definition, the global numbers of species, including those of important and well-studied life forms such as trees, still remain largely unknown. Here, based on global ground-sourced data, we estimate the total tree species richness at global, continental, and biome levels. Our results indicate that there are ∼73,000 tree species globally, among which ∼9,000 tree species are yet to be discovered. Roughly 40% of undiscovered tree species are in South America. Moreover, almost one-third of all tree species to be discovered may be rare, with very low populations and limited spatial distribution (likely in remote tropical lowlands and mountains). These findings highlight the vulnerability of global forest biodiversity to anthropogenic changes in land use and climate, which disproportionately threaten rare species and thus, global tree richness.

Abstract

In this Letter, the middle initial of author G. J. Nabuurs was omitted, and he should have been associated with an additional affiliation: ‘Forest Ecology and Forest Management Group, Wageningen University and Research, Wageningen, The Netherlands’ (now added as affiliation 182). In addition, the following two statements have been added to the Supplementary Acknowledgements. (1): ‘We would particularly like to thank The French NFI for the work of the many field teams and engineers, who have made extraordinary efforts to make forest inventory data publicly available.’ (1): ‘Sergio de Miguel benefited from a Serra- Húnter Fellowship provided by the Generalitat of Catalonia.’ Finally, the second sentence of the Methods section should have cited the French NFI, which provided a national forestry database used in our analysis, to read as follows: ‘The GFBi database consists of individual-based data that we compiled from all the regional and national GFBi forest-inventory datasets, including the French NFI (IGN—French National Forest Inventory, raw data, annual campaigns 2005 and following, https://inventaire-forestier.ign.fr/spip.php?rubrique159, site accessed on 01 January 2015)’. All of these errors have been corrected online.

Abstract

The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools 1,2 , sequester carbon 3,4 and withstand the effects of climate change 5,6 . Characterizing the global distribution of these symbioses and identifying the factors that control this distribution are thus integral to understanding the present and future functioning of forest ecosystems. Here we generate a spatially explicit global map of the symbiotic status of forests, using a database of over 1.1 million forest inventory plots that collectively contain over 28,000 tree species. Our analyses indicate that climate variables—in particular, climatically controlled variation in the rate of decomposition—are the primary drivers of the global distribution of major symbioses. We estimate that ectomycorrhizal trees, which represent only 2% of all plant species 7 , constitute approximately 60% of tree stems on Earth. Ectomycorrhizal symbiosis dominates forests in which seasonally cold and dry climates inhibit decomposition, and is the predominant form of symbiosis at high latitudes and elevation. By contrast, arbuscular mycorrhizal trees dominate in aseasonal, warm tropical forests, and occur with ectomycorrhizal trees in temperate biomes in which seasonally warm-and-wet climates enhance decomposition. Continental transitions between forests dominated by ectomycorrhizal or arbuscular mycorrhizal trees occur relatively abruptly along climate-driven decomposition gradients; these transitions are probably caused by positive feedback effects between plants and microorganisms. Symbiotic nitrogen fixers—which are insensitive to climatic controls on decomposition (compared with mycorrhizal fungi)—are most abundant in arid biomes with alkaline soils and high maximum temperatures. The climatically driven global symbiosis gradient that we document provides a spatially explicit quantitative understanding of microbial sym, 33Smithsonian’s National Zoo and Conservation Biology Institute, Washington, DC, USA. 34Institute of Tropical Forest Conservation, Mbarara University of Sciences and Technology, Mbarara, Uganda. 35Isotope Bioscience Laboratory - ISOFYS, Ghent University, Ghent, Belgium. 36Integrated Center for Research, Development and Innovation in Advanced Materials, Nanotechnologies, and Distributed Systems for Fabrication and Control (MANSiD), Stefan cel Mare University of Suceava, Suceava, Romania. 37Department of Forest Sciences, Luiz de Queiroz College of Agriculture, University of São Paulo, Piracicaba, Brazil. 38Bavarian State Institute of Forestry, Freising, Germany. 39Manchester Metropolitan University, Manchester, UK. 40Institute of Biology, Geobotany and Botanical Garden, Martin Luther University Halle-Wittenberg, Halle-Wittenberg, Germany. 41German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, Leipzig, Germany. 42Department of Agriculture, Food, Environment and Forest (DAGRI), University of Firenze, Florence, Italy. 43Biological Institute, Tomsk State University, Tomsk, Russia. 44Department of Spatial Regulation, GIS and Forest Policy, Institute of Forestry, Belgrade, Serbia. 45Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT, USA. 46Tropical Forests and People Research Centre, University of the Sunshine Coast, Maroochydore, Queensland, Australia. 47Faculty of Natural Resources Management, Lakehead University, Thunder Bay, Ontario, Canada. 48Key Laboratory for Humid Subtropical Eco-Geographical Processes of the Ministry of Education, Fujian Normal University, Fuzhou, China. 49Institute of Integrative Biology, ETH Zürich, Zurich, Switzerland. 50IFER - Institute of Forest Ecosystem Research, Jilove u Prahy, Czech Republic. 51Global Change Research Institute CAS, Brno, Czech Republic. 52Nicholas School of the Environment, Duke University, Durham, NC, USA. 53Department of Biology, University of Missouri-St Loui

Abstract

Forord: Denne rapport giver en kort beskrivelse af Areal Informations Systemet (AIS), som er et databasesystem med natur- og miljødata, som kan stedfæstes geografisk. Projektet er gennemført i perioden 1996-2000 som et samarbejdsprojekt mellem Danmarks Miljøundersøgelser (DMU), Danmarks og Grønlands Geologiske Undersøgelse (GEUS), Forskningscentret for Skov & Landskab (FSL), Skov- og Naturstyrelsen (SNS), Miljøstyrelsen (MST), Energistyrelsen (ENS), Kort & Matrikelstyrelsen (KMS), Landsplanafdelingen (LPA), Ministeriet for Fødevarer, Landbrug og Fiskeri, amterne, Københavns Kommune samt Farvandsvæsenet. Projektets formål er at sammenstille data til anvendelse i et geografisk informationssystem (GIS), som indeholder en national arealkortlægning set ud fra en natur- og miljømæssig synsvinkel. Areal Informations Systemets opbygning og indhold af data er kort beskrevet i nærværende rapport. I forbindelse med projektet er der udarbejdet en række metoder, som ligeledes er beskrevet i rapporten. Det er hensigten, at Areal Informations Systemet skal blive et centralt værktøj i såvel det administrative arbejde som overvågning og forskning i Miljø- og Energiministeriet, men også for andre institutioner og enkeltpersoner med interesse for natur- og miljøforhold i Danmark. Yderligere oplysninger om Areal Informations Systemet, herunder adgangsforhold, kan fås på DMU's hjemmeside med følgende adresse: http://ais.dmu.dk/ Projektet er finansieret af Miljø- og Energiministeriet, mens en række institutioner har bidraget med data i betydeligt omfang. Projektet består af følgende delprojekter: Delprojekt 1. Sammenstilling af det nationale Arealanvendelseskort Delprojekt 2. Hydrologisk information Delprojekt 3. Klassifikation af skove og udvalgte terrestriske naturtyper Delprojekt 4. Klassifikation af bebyggede områder Delprojekt 5. Kortlægning af jordarter på landjorden Delprojekt 6. Sedimenttyper for indre danske farvande Delprojekt 7. Marin dybdemodel Delprojekt 8. Kortlægning af administrative områder Delprojekt 9. Kortlægning af adgang til offentlige registre og digitale kort. Delprojekt 10. Etablering af satellitbilledarkiv Indledning: Areal Informations Systemet er det første forsøg på at integrere geografiske data inden for natur- og miljøområdet i Danmark, hvilket vil give helt nye muligheder for anvendelsen af GIS data indenfor Miljø- og Energiministeriets resort. Miljø- og Energiministeriets arbejde med administration, overvågning og forskning vedrørende natur- og miljøforholdene i Danmark medfører et behov for en sammenhængende og ensartet kortlægning. Geografiske informationssystemer (GIS) sammenstiller information, som er knyttet geografisk til landskabet, hvilket gør Areal Informations Systemet særdeles velegnet til at samle og præsentere informationer om natur- og miljøtilstanden. Areal Informations Systemets temaer indeholder information om naturen for specifikke arealtyper og informationerne kan direkte anvendes til statistikker over naturtyper, arealanvendelse etc. Også i forbindelse med nye administrative initiativer, samt opfølgning på gældende handlingsplaner, vil Areal Informations Systemet være særdeles anvendeligt. Den landsdækkende overvågning af vandmiljøet NOVA 2003, som gennemføres i tæt samarbejde mellem Miljø- og Energiministeriet og amterne, anvender en række oplande, samt målestationer i vandløb, søer og havet. En væsentlig del af disse informationer findes nu i Areal Informations Systemet, hvilket vil bidrage til at forbedre den nationale overvågning. Systemet kan endvidere udbygges med nye informationer efterhånden som nuværende overvågningsprogrammer ændres eller nye igangsættes. Areal Informations Systemet forventes således at blive et centralt redskab i den fremtidige naturovervågning. Areal Informations Systemet forventes også at blive anvendt i den fremtidige miljøforskning. De geografiske data vil gøre det muligt bl.a. at opstille modeller og beregne scenarier, som i langt større omfang end hidtil indbygger det geografiske element i analyser af natur- og miljøforhold. Data vil også kunne anvendes til analyse af miljøforhold i byer. Hvis Areal Informations Systemet på længere sigt bliver tilgængeligt på Internettet, vil data være særdeles velegnede til information af borgerne. Baggrund: Geografiske data indsamles i Danmark af mange forskellige offentlige og private institutioner, som bl.a. omfatter Kort & Matrikelstyrelsen, Miljø- og Energiministeriet, Ministeriet for Fødevarer, Landbrug og Fiskeri, amter, kommuner, samt gas- og telefonselskaber. Frem til 1995 havde kun enkelte institutioner i Miljø- og Energiministeriet erfaring med indsamling af digitale geografiske data. Disse data blev i høj grad anvendt til specifikke formål, hvilket gjorde det vanskeligt at opnå et samlet billede af natur- og miljørelaterede forhold på landsplan. Den manglende koordinering medførte endvidere, at de benyttede datastrukturer var forskellige, og i nogle tilfælde ikke digitale, hvilket besværliggjorde integrationen af data indsamlet af de forskellige institutioner. Manglen på et fælles kortgrundlag og datastruktur var tillige en af barriererne for samarbejde på tværs af ministeriets institutions- og faggrænser. Endvidere var der et udtalt behov for ajourføringer af tidligere kortlægninger af arealanvendelse og naturtyper, da tidligere kortlægninger fra 1970'erne og 1980'erne havde en utilfredsstillende detaljeringsgrad. Behovet for et samlet landsdækkende datasæt vedrørende natur- og miljøforhold var udtalt, hvorfor udviklingen af Areal Informations Systemet blev igangsat af Miljø- og Energiministeriet i 1996. Projektet er gennemført i tæt samarbejde med de andre institutioner, som indsamler data vedrørende natur- og miljøforholdene i Danmark. Formål: Formålet med Areal Informations Systemet er i henhold til projektbeskrivelsen: # Etablering af et landsdækkende kort over arealanvendelsen med udgangspunkt i data fra 1996 eller så tæt på dette tidspunkt som muligt. Data fra topografiske kort 1:25.000 og TOP10DK 1:10.000 indgår. # Etablering af et landsdækkende satellitbilledarkiv baseret på billeder fra Landsat 5 satellitten. # Tilvejebringelse af supplerende datasæt omfattende hydrologisk information (vandløb, søer, oplande, målestationer), vegetation (skove og udvalgte naturtyper), byområder (arealanvendelse), administrative områder (planlægning, beskyttelse), geologi (overfladegeologi og marin geologi), samt marin dybdemodel. # Etablering af dataadgang for Miljø- og Energiministeriets institutioner til AIS-data. # Afprøvning af systemet i forhold til konkrete projekter. # Formidling af produkterne til brugerkredsen.

Abstract

Two commercial laser dendrometers were tested under controlled and field conditions, and contrasted with alternative instruments. Testing focused on height measurement, but also considered distance and remote diameter measurements. Both laser instruments gave very precise estimates, but showed some bias. Users of these and other 'high-tech' instruments are reminded that precision is not synonymous with accuracy. Users should not become complacent about the submillimetre readout, but should calibrate instruments to examine if users' accuracy requirements are satisfied. Instruments may need to be re-calibrated each measurement season and after any mishandling.
