Himalayan region is climate sensitive, even a tiny fluctuation in climate can markedly affect numerous species and their habitats. Moreover, the Himalayan region is inhabited by some of the most threatened and endangered biodiversity on Earth, including habitat specialists and endemic species, which may accelerate the extinction of some species. Hence, species affected by climate change should be monitored and identified as faunal indicators of climate change in (Chitwan Annapurna Landscape) CHAL. For that, we compared studies conducted by the National Trust for Nature Conservation (NTNC) and World Wildlife Fund for Nature (WWF Hariyo Ban Program). First, we identified the common and overlapping species. Second, we identified the critical species for climate monitoring based on habitat range, elevation, role as habitat specialist/generalist, and impact obs...

The vegetation change study is more vital as vegetation is the part of every ecosystems and functioning of the park. There had been limited study regarding vegetation changes and impact of climatic and environmental factor on greenery in Nepal. To fill this gap, our study applied satellite based NDVI, precipitation and soil moisture data to inspect changes in vegetation and their relation with climatic variables in Sagarmatha National Park (SNP). Our study revealed that the greenery contributors, forests, shrubs, grasslands and agricultural lands had increased during period of 2000-2018. These changes was due to reverse effect of both precipitation and soil moisture. In light of these findings, we assured that the greenery of the park was well preserved during these 18 years. Our research provided ecological and social implication for the SNP region as plan and polices regarding wellbeing of both vegetation and local dwellers could be formulated based on vegetation condition of park.

This study analyses the temporal and spatial changes of Normalized Difference Vegetation Index (NDVI) in the Langtang National Park (LNP), Nepal, during 2000 - 2018, using the MODIS 16-day NDVI product, and the ERA-5 precipitation and temperature reanalyzes. Regression models were applied to estimate temporal trends in NDVI, and Pearson correlations between NDVI and climatic variables (i.e., temperature and precipitation) were employed to assess vegetation responses to climate change. Average annual NDVI increased significantly (0.002yr-1, p = 0.001), and the average growing season (AGS: April-October) NDVI also increased significantly (overall, 0.0023yr-1) including in spring (April-May, 0.003yr-1) and autumn (September-October, 0.002yr-1). During summer (June-August), NDVI increased by 0.002yr-1 (p > 0.05). ...
