Great Basin Naturalist Memoirs


Seven aquatic and semiaquatic communities surrounding Utah Lake and its bays are described. Similarities and differences in the community types are discussed. Prevalent species in each type are given. The flora contained 483 species, 150 of which were prevalent enough to be included in the quantitative data analysis. Distichlis stricta was the most important and widespread species. Total cover varied in the communities from 10 to 77 percent. Asexual reproduction was shown to increase in importance as moisture in the soil increased. Introduced exotic species were shown to invade most successfully those habitats that show the greatest variability in moisture and/or those that have the greatest internal variation.
