Figure 64-We1 sedge meadow tundraof Eriophorum angusiifolium and Carexaquafrlrs in arctic Alaska.Closely related types-Wet sedge meadow tundra is similar to subarctic lowlandsedge wet meadow (lll.A.3.g.), which occupies similar sites within the tree line.Although some species commonly dominate both, many species dominating thesubarctic sites are not present in the Arctic. Also, Eriophorum angusfifolium is lesscommonly dominant on the subarctic sites than it is in the Arctic. This unit is alsosimilar to wet sedge-grass and wet sedge-herb meadow tundras (which are esentiallyvariants of wet sedge meadow tundra) but lack conspicuous grass or broad-leavedherb elements. Fresh sedge marsh also is similar but does not include any tundra(arctic) communities, is permanently flooded with relatively deep water, and isdominated by genera other than Carex.PhotoQraphs--Batten 1977, figure 13 (aerial view); Bergman and others 1977,plates I, Il, and 111; Churchill 1955, figure 9; Drew and Shanks 1965, figure 14;Hettinger and Janz 1978, plate 10E; Johnson and others 1966, figures 8, 9, 15,and 16; Komarkova and Webber 1978, figure 66; Racine 1978a, figures 12 and 13;Racine and Anderson 1979, figure 24; Webber 1978, figure 7; figure 64, thispublication.Primary references-Drew and Shanks 1965, Racine and Anderson 1979, Webberand Walker 1975.Communities-Eriophorm angustifoliurn (Craighead and others 1988, Holowaychukand Smeck 1979, Murray 1974, Racine 1976, Racine and Anderson 1979, Viereck1963, White and others 1975).
