P. De Beereleels 1966 Journal 12 August Meade River Coal Mtn, 157°25' W, 37°29' N, Alaska Where the active dunes are invaded by the polygonal habitats, a sparsely sandy- loose polygon (very like the Salix reticulata polygons) develops, and a few plants seem to grow better in their bare area where else - In essence the vegetation pattern seems to resolve on degree of drainage; degree of micro-topographic relief, and the persistence of snow+ Ice. Bird utilization does not seem to figure recognition of these, and stubbids utilize only a few. The dry habitats are used by feeding Semipalmated Sandpipers, bred for nesting, by Plovers and Terns, which appear to do much feeding in marshes and in low-polygon habitats. Deebelin and Semipals nest almost entirely in the Eriophorum-Carex (low polygons), and the latter fringes here primarily as well. Pectorals, Semipalmated, and Phalaropes nest in the pond-wash area and do most of their feeding there as well; make a seen in the order listed from shallow to deep water situations; in addition, Semipals used the pond margin (river margin) extensively; and in August the
