  1. Other biodiversity: Restore habitat along watercourses

    A before-and-after site comparison in 1991–2008 in six sites along the Putah Creek, California, USA, found different fish communities before and after a change in river flow. Fish: Different communities were found 6 km and 21 km from a dam, after the change, but no differences were found 0, 16, 25, and 30 km from the dam. Methods: Habitat was restored through a change in hydrology. Three-day pulses, between 15 February and 31 March, followed by a month of higher flows, were used to initiate spawning. Five-day pulses (in November or December) were used to promote salmon Oncorhynchus tshawytscha migration. Six sites at different distances from a dam (0, 6, 16, 21, 25, or 30 km) were sampled annually in September and October for eight years before and nine years after the change in the flow (1991–2008). Fish were captured through electroshocking.
