Sites of major flyway importance for the 10 large-bodied waterbirds in the Yangtze River Floodplain. The map shows proposed sampling points for the future juvenile ratio field survey (green), all of which were located on key lakes (a Poyang Lake, N = 108; b East Dongting Lake, N = 13; c Longgan Lake, N = 6; d Shengjin Lake, N = 15; e Caizi Lake, N = 6; f Chen Lake, N = 7). N in each case is the number of planned points. Remaining points (shown in white) that were surveyed in 2016–2019 are not proposed to be sampled in the future unless circumstances change
