mortality of waterfowl on a hypersaline wetland as a result of salt encrustation.approximately 300 geese, primarily lesser canada geese (branta canadensis parvipes) were found unable to fly or dead on a small hypersaline lake (conductivity 77,000-90,000 mumhos/cm) in western saskatchewan in september 1985. the birds were heavily encrusted with sodium sulfate crystals. dead birds that were necropsied had aspirated lake water and had evidence of acute muscle degeneration. the live geese (155) were captured and moved to nearby freshwater wetlands where most apparently survived. ...19873820414
