RESUMO

Background: Biodiversity conservation is becoming challenging day by day. For this, it is essential to understand the distribution, habitat, and impact of anthropogenic activities on animals at risk. We assessed the suitable habitats and anthropogenic impacts on Asiatic black bears, common leopards, musk deer, and snow leopards in and outside the protected areas of Gandaki Province, Nepal. Methods: We collected the presence locations of Asiatic black bears, common leopards, musk deer, and snow leopards based on scats and other signs. We employed the Maximum Entropy (MaxEnt) tool to identify suitable habitats of our studied species and their anthropogenic impacts on them. Results: The total suitable habitat of the common leopard was found to be 6,052 km2, followed by the Asiatic black bear (5,819 km2), snow leopard (4,447 km2), and musk deer (1,690 km2) in Gandaki Province. Most of the areas of suitable habitat for common leopards and Asiatic black bears were outside the protected areas, and for musk deer and snow leopards were inside the protected areas. Elevation was the most important variable determining habitat suitability of Asiatic black bear, common leopard, and musk deer, whereas the distance to water was the most important variable determining habitat suitability of snow leopard. Asiatic black bears, common leopards, and musk deer face significant anthropogenic impacts, but snow leopards face some anthropogenic impacts. Conclusion: Managing these animals' habitats inside and outside protected areas is essential. Hence, biodiversity conservation and livelihood opportunities should be balanced in the Himalayas on a win-win basis.

RESUMO

Vultures are ecologically important primarily because of their scavenging role in cleaning carcasses of the environment. Because of anthropogenic impacts, the Egyptian vulture (Neophron percnopterus) has suffered catastrophic declines in parts of its range and, thus, information about its global distribution and factors influencing its occurrence within this range are essential for its conservation. To this end, we estimated the global distribution of Egyptian vulture and variables related to this distribution. We used occurrence points (n = 4740) from online data sources and literature, environmental variables related to these sites and Maximum Entropy software to model the distribution of this species and its relationship to environmental variables during the entire year, breeding and overwintering. Out of ~ 49 million km2 study area, the Egyptian vulture had a predicted range of 6,599,508 km2 distributed across three continents: Africa, Asia and Europe. The densest distribution was in Southern Europe, India and Northern Africa and a sparser distribution was around Mid and Western Africa, the Middle East and Afghanistan. Climate was related to the vulture's most probable range: in particular medium temperature seasonality and low precipitation during the coldest yearly quarter were important variables regardless of the season of observations examined. Conservation of identified habitats and mitigation of anthropogenic impacts to conserve these vultures are recommended for immediate and long-term conservation of the Egyptian vulture globally.

RESUMO

Almost all countries have imposed large-scale mobility restrictions (or lockdown) to stop the spreading of the novel coronavirus (COVID-19). The mobility restriction has disrupted all types of business; causing a devastating impact on countries' economies; and pushing millions of people into extreme poverty. Scientists have been assessing the impact of COVID-19 lockdown on various fronts but there is limited scholarship in the forestry sector. We navigated the impact of COVID-19 lockdown on the forestry sector by taking Gandaki Province (21,974 km2) of Nepal as a case. Employing semi-structured interviews (n = 62) with all ten stakeholder groups, literature review and media analysis, our study revealed that the COVID-19 lockdown suspended all types of forestry and ecotourism businesses; obstructed research and monitoring activities; halted capacity development and extension services; impacted forest development work; and increased incidences of illegal logging and poaching and trafficking of wildlife. Because of the complete shutdown of businesses, the forestry sector of Gandaki province lost 9.6 million USD and 3.2 million man-days of employment during the lockdown period. The economic cost of the lockdown was 1.73 million USD for NTFPs traders, 1.26 million USD for ecotourism entrepreneurs, 0.55 million USD for the community forest user groups and 0.24 million USD for the smallholder or private forest owner. We suggested four post-COVID recovery pathways, including sustainable forest management, nature-based tourism, improvement of forest products value chain and community-based natural resource management to bounce back from the loss. As the current pandemic is most likely to derail the Sustainable Development Pathways of several countries, including Nepal and necessitates the need for an immediate response, the finding and recommendation of our study may inform decision-makers to reimage post-pandemic recovery and leverage sustainable development.

RESUMO

On a global scale, about 15.5% of forests are administered through community-based forestry programs that offer the opportunity for enhanced carbon sequestration while maintaining the supply of more traditional goods and services such as cooking fuels, animal fodder and bedding. A challenge in community forest (CF) management is to realize their carbon value without compromising their role in the provision of these traditional goods and services. In this study of CF dominated by Pinus roxburghii in the Phalebas region of Nepal, the impacts of stand composition and geographic aspect on aboveground forest carbon is investigated as a means to optimize CF management for both traditional values and for emerging carbon market values. The aboveground carbon of mixed and monospecific stands of Pinus roxburghii was estimated using a combination of destructive sampling and species-specific allometric equations. On average, monospecific stands contained 106.2 Mg C ha-1 in aboveground tree biomass, significantly more than mixed stands at 73.1 Mg C ha-1 (p = 0.022). Similarly, stands growing on northern aspects (northeast 124.8 Mg C ha-1, northwest 100.9 Mg C ha-1) stored significantly more carbon (p = 0.002) than southern aspects (southeast 75.3 Mg C ha-1, southwest 57.6 Mg C ha-1), reflecting the more favorable growing conditions of northern aspects. These results suggest monospecific stands planted on northern aspects may be best suited for management to achieve carbon benefits, whilst mixed-species stands on southern aspects may be better suited for biodiversity conservation and supporting livelihoods. To maintain and increase carbon value, community forestry may need to implement nutrient return practices to limit the impact of sustained nutrient removals on stand productivity.
