Reducing human pressure on farmland could rescue China’s declining wintering geese

摘要

Study area and GPS locations of two goose species at their stopover and wintering sites. The study area is the range of a 50 km-buffer around day GPS locations of each goose species. Human pressure refers to the standardized human footprint with a range of 0–50. NCP: Northeast China Plain (the stopover region); YRF: Yangtze River Floodplain (the wintering region); TBG: tundra bean geese (Anser serrirostris); GWFG: greater white-fronted geese (A. albifrons). Red dots indicate TBG GPS records (dark red) and generated absences (light red) and blue dots indicate GWFG GPS records (dark blue) and generated absences (light blue)
