Jackson et al_Multiple habitat use by declining migratory birds necessitates joined-up conservation

Field data comprising shorebird counts and biophysical survey variables, used in generalised linear mixed-effects models described in the manuscript. Survey month: 1 = July or August, 2 = September, 3 = October; Tide Height: tide height in cm at the highest or lowest tide point during the survey; Intertidal flats cover: 1 = seawater was against the seawall during the count, 0 = seawater did not reach the seawall during the count; Water cover: % cover of water over the surface area of the whole pond; Distance: distance to seawall measured in kilometres using Google Earth; Vegetation cover: estimated non-water surface area covered by vegetation, measured as <10%, 10-30%, 30-50%, 50-70% or >70%; Bund: number of unvegetated bunds (i.e. the bank surrounding the pond, sometimes called berms) for each pond, 1= at least one unvegetated bund, 0 = no unvegetated bunds; Structures: number of structures (telephone/electricity poles/wires, buildings and trees) within 10m of the perimeter of the pond; Size: pond size measured in hectares using Google Earth; Total Count: count of total shorebird abundance (all individuals of all species).
