    Current future potential distribution of sarus crane (Grus antigone) in Nepal using ensemble modelling
    (Department of Zoology, 2023) Acharya, Rashrni
    Climate change have a significant impacts on the geographic distribution and composition of species across time and space, but little is known about how they affect wetland birds. Therefore, this study was conducted to address the impacts of climate change on the distribution of Sarus Crane across Nepal. Species occurrence and nest location data were collected from the field through direct observation. The current and future potential distribution of the species was identified using ensemble modelling. The model predicted approximately 4.52% (6,659 km xii 2 ) of total Nepal area under current distribution. The suitable area was predicted mostly in western Nepal. Maximum range expansion was found up to 17.33% (12, 2513 km 2 ) for the distribution under SSP5-8.5 scenarios for 2090. The range expansion for the distribution of species is expected to occur almost entire lowland and some Siwalik regions of Nepal by the end of century. Also, the presence of nesting site relies heavily on the waterbody and agricultural marshland. The findings of this research suggests that agricultural and wetland areas should be managed properly for the conservation of Sarus Crane in Nepal.
