Intensive reclamation and revegetation research is being conducted on surface mined lands in North Dakota. Soil samples were collected monthly during the 1975-1977 growing seasons from 5 test plots. Results will be reported for the N. Beulah 2 test plot. The soils were analyzed for the presence of algal species, chlorophyll ..cap alpha.., major cations, anions, and trace elements. Nine species of Chlorophyta, 13 of Cyanophyta, 3 of Bacillariophyta and 1 of Xanthophyta were identified from soil enrichment cultures. A trend analysis showed that time had a positive correlation (p < .01) with the number of species and chlorophyll ..cap alpha.. content. Three cosmopolitan species, Chlorosarcinopsis pseudominor, Chlorococcum humicola and Nitzschia palea were found at all sites and dates. Analysis of 1977 soils showed that 9 new species appeared. Evidence of algal succession indicated that a favorable change in the soil chemistry had occurred. Successful revegetation of surface mined lands is dependent on many factors; the soil environment, including microorganisms, is the most important. The presence of algae may be used as an indicator of improving soil conditions for revegetation.
