Aquatic species and habitats
Continuing human activities threaten the highly prized aquatic resources of the interior Columbia basin. Precipitous declines in native species, particularly Pacific salmon, and a large influx of introduced species have radically altered the composition and distribution of native fishes. Fortunately, areas of relatively high aquatic integrity remain, much of it on federally administered lands. These areas can provide a starting point for protecting and restoring aquatic resources throughout the basin if decisive action is taken.
