Abstract

Few studies have focused specifically on use of Alaskan wetlands by waterfowl. However, substantial information on the values of wetlands is available from studies on individual species or that were conducted for other purposes. Most investigators have found it most effective to classify habitat use on the basis of observed distribution patterns of waterfowl in relation to local physiographic features and vegetation types. Major variations in habitat among regions result from differences in precipitation, summer temperature, length of frost free period, and presence of permafrost. Large areas of intertidal habitat, usually associated with river deltas, are of key importance wherever they occur. Lakes subject to extensive periods of draw-down or that fluctuate with river systems are more productive than those with more stable water levels.
