Abstract According to variations in the level, the waters of Great Salt Lake, Utah, contain 14-27% salt, principally NaCl, and harbor Aphanothece utahensis, Microcystis packardii, Oscillatoria tenuis natans, O. ten. tergestina, Tetraspora lubrica lacunosa and Chlamydomonas sp. The first 2 are instrumental in accumulating CaCO3 and the formation of tufaceous and oolite deposits. The strand is invaded by the following succession: Salicornia rubra, S. utahensis, Allenrolfea occidentalis, Suaeda erecta, S. moquinii, Distichlis spicata, et al. The maximum amount of salt tolerated is 4-6% (%dry wt. of samples) in very wet places and 1-3% in drier places. Strand swamps, springs, deltas and salt marshes are reduced in salt content and are inhabited by Chlorophyceae, Scirpus americanus, S. paludosus, S. olneyi, et al. The flora of the playas is much like that of the strand at the line of invasion but is less salty and drier. Alkaline plains and dunes present a low shrubby vegetation. The soil is 0.6-0.8% salt. The edaphic climax association is Sarcobatus vermiculatus-Atriplex confertifolia; other associations are Atriplex and Kochia. Prominent communities are Kochia-Eurotia, K.-Suaeda, Sarcobatus-Grayia and Chrysothamnus. Graminaceae and Cruci-ferae form the vernal aspect. Hot mineral springs are 5% salt, 61[degree] C, and are rich in Myxophyceae. || ABSTRACT AUTHORS: S. Flowers
