Species-Soil Relationships on Sulfate Dominated Soils of South Dakota

Species-soil relationships were studied at Stink and Bitter lakes in South Dakota. The effect of high salt concentrations on species distributions was established. The sulfate dominated soils appear to have a vegetation similar to that of chloride dominated soils of Nebraska, with an index of similarity equalling 90.0%. The succulents invading the salt pan appear to represent a cyclical invasion stage which disappears during periods of drouth, and which is not necessarily a primary stage of succession.
