From: Reducing human pressure on farmland could rescue China’s declining wintering geese
Human pressure on farmland and wetland/grass in the study area. 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); SA: study area (see Fig. 1). Asterisks indicate a significant difference in human pressure; error bars are 95% confidence intervals around the mean
