This paper uses Vietnam – where overexploitation of wildlife resources is a major threat to biodiversity conservation – as a case study to examine how government officials perceive the impacts of COVID-19 on wildlife farming, as well as the opportunities and challenges presented for sustainable wildlife management. Findings show Vietnamese government officials perceive COVID-19 to have had mixed impacts on wildlife conservation policies and practice. While the pandemic strengthened the legal framework on wildlife conservation, implementation and outcomes have been poor, as existing policies are unclear, contradictory, and poorly enforced. Our paper also shows policymakers in Vietnam are not in favor of banning wildlife trade. As our paper documents the immediate impacts of the pandemic on wildlife farming, more research is necessary to analyse longer-term impacts.

Tropical and subtropical Asia’s valued tree species under threat
Tree diversity in Asia’s tropical and subtropical forests is central to nature-based solutions. Species vulnerability to multiple threats, which affect provision of ecosystem services, is poorly understood. We conducted a region-wide, spatially explicit assessment of the vulnerability of 63 socioeconomically important tree species to overexploitation, fire, overgrazing, habitat conversion, and climate change. Trees were selected for assessment from national priority lists, and selections were validated by an expert network representing 20 countries. We used Maxent suitability modeling to predict species distribution ranges, freely accessible spatial data sets to map threat exposures, and functional traits to estimate threat sensitivities. Species-specific vulnerability maps were created as the product of exposure maps and sensitivity estimates. Based on vulnerability to current threats and climate change, we identified priority areas for conservation and restoration. Overall, 74% of the most important areas for conservation of these trees fell outside protected areas, and all species were severely threatened across an average of 47% of their native ranges. The most imminent threats were overexploitation and habitat conversion; populations were severely threatened by these factors in an average of 24% and 16% of their ranges, respectively. Our model predicted limited overall climate change impacts, although some study species were likely to lose over 15% of their habitat by 2050 due to climate change. We pinpointed specific natural areas in Borneo rain forests as hotspots for in situ conservation of forest genetic resources, more than 82% of which fell outside designated protected areas. We also identified degraded areas in Western Ghats, Indochina dry forests, and Sumatran rain forests as hotspots for restoration, where planting or assisted natural regeneration will help conserve these species, and croplands in southern India and Thailand as potentially important agroforestry options. Our results highlight the need for regionally coordinated action for effective conservation and restoration.
Combining camera trap surveys and IUCN range maps to improve knowledge of species distributions
Reliable maps of species distributions are fundamental for biodiversity research and conservation. The International Union for Conservation of Nature (IUCN) range maps are widely recognized as authoritative representations of species’ geographic limits, yet they might not always align with actual occurrence data. In recent area of habitat (AOH) maps, areas that are not habitat have been removed from IUCN ranges to reduce commission errors, but their concordance with actual species occurrence also remains untested. We tested concordance between occurrences recorded in camera trap surveys and predicted occurrences from the IUCN and AOH maps for 510 medium- to large-bodied mammalian species in 80 camera trap sampling areas. Across all areas, cameras detected only 39% of species expected to occur based on IUCN ranges and AOH maps; 85% of the IUCN only mismatches occurred within 200 km of range edges. Only 4% of species occurrences were detected by cameras outside IUCN ranges. The probability of mismatches between cameras and the IUCN range was significantly higher for smaller-bodied mammals and habitat specialists in the Neotropics and Indomalaya and in areas with shorter canopy forests. Our findings suggest that range and AOH maps rarely underrepresent areas where species occur, but they may more often overrepresent ranges by including areas where a species may be absent, particularly at range edges. We suggest that combining range maps with data from ground-based biodiversity sensors, such as camera traps, provides a richer knowledge base for conservation mapping and planning.
Willingness to Pay for Conservation of the Asian Elephant in Nakai Nam Theun National Protected Area in Laos
The Asian elephant (Elephas maximus) is an ecologically important species in the forest ecosystem of Laos. The species is endangered and on the edge of extinction owing to illegal hunting, destruction of elephant habitat, and forest degradation. Payment for conservation could be one of the potential mechanisms to enhance Asian Elephant conservation efforts. This paper aims to estimate local residents’ Willingness to Pay (WTP) for conservation of the Asian elephant in Nakai-Nam Theun National Park (NNT NP) in Laos, which is a recognised “Key Biodiversity Area” within the Indo-Burma biodiversity hotspot. The data were collected using a self-administered questionnaire survey, with a total of 490 respondents living adjacent to the NNT NP, covering seven villages in two districts in Khammouane Province, Laos. The study employed the Contingent Valuation Method (CVM) to identify the factors affecting WTP. The results showed that respondents were willing to pay a significant amount of money in the form of increasing activities for conservation and protection of NNT NP. Mean WTP for the conservation of the Asian elephant was $8 per household per year. Approximately 62% (303 local people) of the respondents were willing to pay for the conservation of the Asian elephant. The research findings will be helpful for planners and decision makers to formulate better future strategies for conservation of Asian elephants in Laos and in similar developing countries in the Southeast Asia region.
FTA Highlight No.3 – Conservation of Tree Biodiversity and Sustainable Forest Management
Forests and trees are critical for the survival of life on earth. They conserve a tremendous biodiversity and fulfill essential ecosystem services such as climate regulation, cycling of nutrients and water. They contribute to food and nutrition security, are a major source of raw materials and offer countless livelihood opportunities. However, forests and trees are increasingly threatened by anthropogenic pressures such as overexploitation and land conversion, which are intensified by climate change. At the same time countless tree species and their forest genetic resources (FGR) with exceptional potential uses for supporting the global transition to low carbon food systems and the UN decade on Ecological Restoration are badly conserved and remain critically underutilized. For the last 10 years, the FTA program has set in place research activities that focused on understanding pressures on and threats to populations of socio-economically important tree species; formulating effective, efficient and equitable safeguards for tree genetic resources that are adapted to the local context and species characteristics; and promoting conservation and characterization of germplasm of high-value tree species from forests to farms. FTA has also conducted a range of ecosystem- and landscape-level research projects that explored how silvicultural and monitoring practices can support sustainable timber production while ensuring delivery of multiple ecosystem services, including biodiversity conservation, carbon storage, livelihood support and nutrition security from forest foods. Much of the program’s later work focused on multiple-use forest management. This review of the program’s most salient experiences — derived from a decade of collaborative research — presents a portfolio of the most promising solutions and the significant contributions that FTA has provided to global conservation and sustainable use of tree biodiversity. These achievements also contribute to the international policy arena, particularly to the strategic objectives of various conventions (the Convention on Biological Diversity, United Nations Framework Convention on Climate Change, United Nations Convention to Combat Desertification), and to the efforts led by the Food and Agriculture Organization (FAO) to develop a global conservation strategy for forest genetic resources.
Engaging with the future: framings of adaptation to climate change in conservation
The term ‘adaptation’ is commonplace in conservation research and practice, but often without a reflection on the assumptions, expectations, or frames of reference used to define goals and actions. Communities of practice (e.g. conservation researchers, protected areas managers) have different interpretations of climate change impacts on biodiversity and different ways of defining, operationalizing and implementing adaptation. Their cognitive and motivational expectations for the future are associated with different paths to reach such desired futures. To understand how adaptation is framed in conservation, we undertook a systematic review with a thematic synthesis of the definitions of the term as used in the academic conservation literature. From a sample of 150 articles, only 36 provided a definition of adaptation. We critically appraised the explicit definitions to identify emergent themes that represent particular adaptation approaches. Themes were then grouped, and each group was assigned to a scholarly tradition, onto-epistemological approach and theoretical perspective. Based on theoretical perspectives on social change, we propose a framework (including individual cognitive basis, social interactions, and openness to alternatives) to analyse how change is framed in the definitions and how the framings influence adaptation options. The grouped themes represent passive, active, or indirect adaptation approaches. We used these themes to generate a conceptual model to guide conservation researchers and practitioners engaged in climate adaptation research, policy and management to aid reflection and understanding of the options available to design adaptation agendas and allow negotiation of diverse interests, views and expectations about the future.
Achieving Global Biodiversity Goals by 2050 Requires Urgent and Integrated Actions
Human impacts on the Earth’s biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urgently and in an integrated manner.
Bridging the research-implementation gap in IUCN Red List assessments
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is central in biodiversity conservation, but insufficient resources hamper its long-term growth, updating, and consistency. Models or automated calculations can alleviate those challenges by providing standardised estimates required for assessments, or prioritising species for (re-)assessments. However, while numerous scientific papers have proposed such methods, few have been integrated into assessment practice, highlighting a critical research–implementation gap. We believe this gap can be bridged by fostering communication and collaboration between academic researchers and Red List practitioners, and by developing and maintaining user-friendly platforms to automate application of the methods. We propose that developing methods better encompassing Red List criteria, systems, and drivers is the next priority to support the Red List. © 2021 Elsevier Ltd
The number of tree species on Earth
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.
Assessment of Potential Ecotourism Site in Xaisomboun, Central Laos
Appropriate ecotourism planning is crucial for sustainable ecotourism development in developing countries including Laos. The primary objective of this research was to identify the potential sites for ecotourism in order to assist in planning and decision making to ensure the sustainable natural forest resource management. GIS data analysis was undertaken to assess the potential sites for ecotourism. We used seven factors describing biophysical characteristics; forest cover, water, elevation, slope, proximity to village, road accessibility and historical attractive sites. It was found that there is around 1200 ha of the entire area of Xaisomboun province which is the most suitable for inland recreational activities, about 1980 ha for beautiful ecological sceneries, roughly 1143 ha for historical tourism activity sites, and finally 1031 ha of a total area that most suitable for multipurpose ecotourism activities. These most suitable areas are located mostly in the protected areas, dense forests and high value of natural resources. These are also major attractions for historical and country revolutions. There is a need to incorporate appropriate infrastructures and local engagement and services. The result is useful for ecotourism development and great benefit in terms of sustainable social-economic development, conservation of biodiversity and other ecosystem services.
