Abstract

The aim of this project is to document the effects of Jackson Lake Dams on flows and stability of the Snake River, and the subsequent impact of these changes on floodplain vegetation and related resources. Vegetation maps were constructed from 1945 and 1989 aerial photography and field surveys. Using these data, the AA. determined how vegetation is directly related to the number of years since each portion of the floodplain was last occupied by the channel. The vegetation has changed from a flood-pulse dominated mosaic to a more terrestrial-like pattern of succession. Changes in the Snake River and its floodplain have direct implications on habitat, safety of rafting and canoeing, and biodiversity at the community and species levels
