| 説明 | Brush Creek, located in southwest Oregon is a tributary that feeds the Umpqua River. The Brush Creek watershed contains important habitat for coho salmon, winter steelhead, cutthroat trout, and Pacific lamprey. Historic practices of stream cleaning (removing all the logs from the stream) unfortunately left Brush Creek with poor habitat for fish and other organisms. The “bedrock dominated” habitat had very little gravel for fish to spawn in and very few deep pools that provided cover for adult and juvenile fish. This is an example of this “simplified” habitat.The Brush Creek watershed restoration project began in 2012 and has placed over 1,000 logs and 4,000 boulders in over 11 miles of stream, drastically improving the fish habitat in the watershed. By placing logs and boulders in to the channel, the logs are able to slow the stream down, thus allowing spawning gravel to drop out during the winter months. The logs and boulders also provide cover during high winter flows for adult and juvenile salmon and trout. The project is a result of a partnership between the Bureau of Land Management, State of Oregon Department of Fish and Wildlife, the Partnership for the Umpqua Rivers, and Lone Rock Timber Company. Future plans include riparian noxious weed removal and planting of native species and effectiveness monitoring of the instream restoration work in the form of photopoints, spawning surveys, and snorkel surveys to count juvenile fish. This restoration work will act as a "band-aid" fix to provide fish habitat until the trees in the Riparian Reserves can grow and fall into the stream providing the source of instream wood and fish habitat into the future. During the 2015 field season the Roseburg District plans additional work in Brush Creek as a part of the watershed restoration project. |
