Forests harbor some 80 % of Earth's terrestrial biodiversity and play a crucial role in sequestering and storing carbon that is linked to their ecological integrity and biological diversity functions. Forest degradation—the loss of forest-ecosystem integrity measured by changes to native-species composition, functional processes, and keystone structures—is a major source of emissions and significant cause of biodiversity decline. Addressing this loss is critically important for fulfilling the Paris Climate Agreement and the Kunming-Montreal Global Biodiversity Framework. Additionally, the United Nations (2021a) Strategic Plan for Forests 2017–2030 calls for a halt to both deforestation and degradation by 2030. However, many countries, particularly in the Global North, fail to fully acknowledge forest degradation as a problem within their own borders, and countries are not presently on track to meet the 2030 deadline. Building from established literature, we propose a principle, criteria, indicator and verifier (PCIV) approach that would enable monitoring of degradation at various scales, ranging from the loss of large, old trees to intact landscapes relative to reference conditions derived from primary, mature, historic, and semi-natural conditions. Degradation drivers include multiple forms of commercial logging and road building that alters native species composition, structure, and functionality. Case studies from three major forested biomes (temperate, boreal, and tropical) illustrate the geographic extent and types of degradation. We highlight an urgent call for countries to better detect and assess the cumulative damages of forest-degradation and to end it as promised.

The combined effects of anthropogenic pressures and climate change are primary causes of land degradation. In the Sahel region, livestock grazing and deforestation threatens ecosystems and the livelihoods of rural communities dependent upon them. Urgent restoration efforts are needed, often structured in large-scale top-down initiatives, while local and adaptable bottom-up approaches are less studied, preventing their dissemination. This study focuses on the potential of assisted natural regeneration through small-scale grazing exclusions to restore degraded drylands of Burkina Faso. We assessed grazing exclusions of 3 ha selected along a temporal gradient in which we conducted detailed tree inventories and compared them with adjacent control plots. We found that grazing exclusions had a higher tree richness (+ 121 %), and density (+ 360 %), a different species composition, and these differences increased with time. They had a higher proportion of young trees, thus a greater regeneration potential. A comparison between two biogeographic regions yielded similar results, suggesting that they are also efficient in more arid landscapes. Our study demonstrates the great potential of small-scale grazing exclusions managed by individual farming households as an adaptative measure to combat land degradation. Due to the voluntary basis of this measure and the ability to adjust their management to maximize benefits while retaining ownership, they are well-accepted by rural communities, who can capitalize by the ecosystems services they provide. They may represent a model system of sustainable use of natural resources which can be upscaled to boost dryland restoration efforts to meet the ambitious targets of our decade.

Insect decline has been documented in an increasing number of studies, but attribution to potential drivers remains challenging. Climate change poses threats to insect biodiversity, and there is still little data on how climate change is already affecting insect communities. We present a resampling study on long-term trends in leafhopper and planthopper communities of dry grassland reserves in Germany, comparing samples from three sampling decades: 1960s, 2000s and 2010s. Diversity and abundance data were related to weather data and to information on conservation management. Insect communities changed significantly with respect to decade, season and seasonal precipitation but not with respect to mean seasonal temperature. Conservation management had limited effect. Specifically, wetter conditions resulted in significantly higher abundance and richness of insect communities. We infer that apparent decline of water availability in dry grasslands - among other drivers on landscape-level - plays a significant role in shaping communities of phytophagous insects in Central European cultural landscapes. Conservation management has to be adjusted to this development.

Land reclamation has significantly reduced tidal flats globally, leading to a sharp decline in shorebird populations and highlighting the urgent need for habitat restoration. Following reclamation, tidal flats are predominantly submerged during high tides, forcing shorebirds to seek roosts. To evaluate the effectiveness of various restoration and management methods on high-tide roosts, we studied shorebird utilization in Southern Jiangsu, China, a crucial staging site along the East Asian-Australasian Flyway. We conducted bird surveys during the autumn migration at six high-tide roosts: aquaculture pond using environmentally-friendly farming (EFF) (Site 1), restored and reserved roost (Site 2), unused reclaimed land (Site 3), unrestored flat (Site 4), restored flat (Site 5), and reclaimed farmland (Site 6). We used Bayesian generalized additive mixed effect models (GAMM) to analyze the effects of tide height and proportion of bare ground on shorebird density at the roost sites, and Permutational Multivariate Analysis of Variance (PERMANOVA) and nonmetric multidimensional scaling (NMDS) to compare community composition between roosts. Results showed that Sites 2 and 3 emerged as the most preferred roosting habitats. The model showed that shorebird density peaks when the proportion of bare ground is at 39 % in a roost. Our results showed that different management practices support different shorebird assemblages and highly variable abundance, with the relative proportion of bare ground, water and vegetation as critical factors in the extent to which shorebirds utilize high-tide roots. Continuous management is essential for the long-term success of restoration efforts, contributing to the understanding of sustainable practices in habitat restoration.

Reintroductions are increasingly occurring in landscapes differing from historical conditions. These novel landscapes often feature unknown connectivity, creating uncertainty around long-term recovery of reintroduced populations. We studied a recovery network of American martens (Waabizheshiwag [Ojibwe], Martes americana) in the Great Lakes region where serial reintroductions have resulted in eight populations with uncertain viabilities. Recent observations suggest dispersal is occurring, although functional connectivity within the network is unknown. To quantify network-wide connectivity and identify corridors, we analyzed >1100 genotyped individuals collected from 2000 to 2023. We hypothesized populations within the recovery network are connected via dispersers, especially from populations in Michigan and Minnesota, and that landscape resistance governs the degree of connectivity. We identified two spatial genetic structures in the network: a cline of relatedness originating in the Upper Peninsula of Michigan and extending into Wisconsin, and a genetically distinct population in Minnesota that were related to the rest of the network's subpopulations via historical translocations. A resistance landscape, parameterized by a resource selection function, revealed connectivity is governed by forest complexity across the Great Lakes recovery network. Notably, anthropogenic fragmentation as well as natural ecoregions elevated resistance and reduced connectivity. These ecoregions feature unique conservation concerns and sometimes conflicting management objectives—further complicating regional species recovery. Key corridors were protected with notable Tribal jurisdiction (Bad River Band of Lake Superior Ojibwe). However, we also identified important gaps in corridor protection within Minnesota. Collectively, these areas represent important opportunities for tribal engagement and land management to facilitate natural dispersal within a recovery network.

Mechanistic approaches have advantages over correlative models for predicting climate change impacts on species currently residing in suboptimal habitat, where anthropogenic induced range contraction reduces the performance of correlative models and results limit contribution to conservation. Here, we combined physiological, behavioral, morphological, ecological and environmental data to simulate the climate change effects on the distribution and reproduction potential (RP) of one of the world's rarest primates, the Hainan gibbon (Nomascus hainanus). Our simulations showed that the only remnant population of this species is currently located outside its stable suitable area with 3 months of cold stress in Hainan Tropical Rainforest National Park, China. The RP of the current home ranges will increase, while the stable suitable area of the Hainan gibbon may increase first and then decline as climate warms due to reduction in cold stress followed by an increase in heat stress. The sharp population decline in 1983–1984 was associated with a period of predicted elevated cold stress, although their causal relationship is unclear. Our novel approach explores climate impacts on the populations' persistence rather than just individual survival, and we recommend the areas with RP > maximum RP × 30 % and without heat stress could be characterized as conservation hotspots. This study showed the feasibility of using biophysical modeling to generate useful information for endangered species, when empirical data are lacking and correlative models may be insufficient.

Understanding occurrence patterns and the quantitative size of populations is essential to protect sea turtles. Here, we analyzed stranding and bycatch data to investigate the habitat use patterns of loggerhead (Caretta caretta) and green turtles (Chelonia mydas) in the seas around the Korean Peninsula, located at the northern range limit of the species in the northwestern Pacific. Depending on data from 116 loggerhead and 106 green turtles collected between 2017 and 2023, their regional and seasonal use patterns were analyzed using sea surface temperature, sea surface salinity, chlorophyll-a, and particulate organic carbon. Additionally, the climate simulation model (CNRM-ESM2–1) was used to assess the changes in the habitat suitability of Korean water under increasing sea temperature scenarios. Both sea turtle species seasonally used the East Sea and Jeju Sea as their main feeding grounds in Korean waters during summer and fall. This could be attributed to an oceanic front, which provides an abundant food source, formed in the East Sea when in contact with the North Korea Cold Current and the East Korea Warm Current. However, sea turtle occurrence decreased from early winter, when the sea temperature dropped below 15 °C, and only a few green turtles were found in the Jeju Sea during winter and early spring. The climate simulation model revealed that sea turtles will likely use Korean waters more frequently in the 2050s and 2100 s following continuously increasing sea temperatures. Our findings suggest that immediate management actions are necessary to conserve sea turtles and prevent additional damage to them in Korean water.

Natural wetlands perform essential ecological functions, but their area has dramatically decreased. Partly to counteract this loss, artificial wetlands have been created. While studies comparing animal communities between artificial and natural wetlands abound, research on their comparative ecological functions is scarce. In particular, vertebrate scavengers in aquatic ecosystems have been little studied despite their critical role in nutrient cycling. This study compared vertebrate scavenger assemblages and their consumption patterns in natural and artificial wetlands in Doñana, Spain, to evaluate the effects of wetland management (natural vs. artificial hydrology) across different seasons. We placed 120 carcasses (carp and chicken) in natural and artificial wetlands. We recorded 22 vertebrate scavenger species efficiently consuming 100 % of carrion in an average of less than two days, highlighting their role in nutrient recycling. Carrion of aquatic-origin was consumed faster and by a greater variety of species than that of terrestrial-origin, facilitating the transport of essential nutrients from water to land. Artificial wetlands exhibited higher efficiency in carrion removal (twice as fast as natural wetlands). However, they hosted less diverse assemblages, dominated by opportunistic and non-native species. This suggests that artificial wetlands are not replacing natural wetlands in terms of biodiversity, despite sustaining water levels and functions. Importantly, ‘kidnapping’ water for irrigation reduces the ability of natural wetlands to maintain ecological functions provided by scavengers. Urgent regulation of water abstraction from aquifers, especially for crop irrigation, is necessary to maintain minimum groundwater levels, preserving the functionality and ecological processes of this critical wetland complex.
