The snow leopard suitable habitat analysis and climate refugia
identification in Qinghai province, China
Abstract
Global climate change poses major challenges for current biodiversity
conservation efforts. Assessing species’ vulnerability to climate change
is a prerequisite for developing effective strategies to reduce emerging
climate-related threats. We used the maximum entropy algorithm (MaxEnt
model) to assess potential changes in snow leopard (Panthera uncia)
suitable habitat in Qinghai Province, China under a mild climate change
scenario. Our results showed that the area of snow leopard suitable
habitat in Qinghai Province was 302,821 km2 under current conditions and
228,997 km2 under 2050’s climatic scenario, and that its mean elevation
would shift upward 90 m. At present, nature reserves protect 38.78% of
the currently suitable habitat and will protect 42.56% of future
suitable habitat. Current areas climate refugia amounted to 212,341 km2,
mainly distributed in Sanjiangyuan, Qilian mountains and surrounding
areas. Our results provide valuable information for formulating
strategies to meet future conservation challenges brought on by climate
stress. We suggest that conservation efforts in Qinghai Province should
focus on protecting areas of climate refugia and on maintaining or
building corridors when planning for future species management.
