[en] Climatological data and the drift fence results from FY-1982 concerning vertebrate census studies are summarized. To facilitate seasonal comparisons, portions of these data are presented with data from past years. Representative important species will be discussed. We summarized our peripheral stream studies, major portions of which were designed and completed during FY-1982. Our findings with respect to potentially threatened or endangered species are presented. Ecological and life history data on some of the more thoroughly studied amphibians are summarized in order to demonstrate the significance of long-term ecological studies to satisfactory environmental assessment. Finally, based on our baseline faunal surveys and concomitant long-term ecological studies, we attempt to predict the biotic consequences of the construction and operation of the proposed DWPF
