The rules establish a desired future condition for riparian vegetation. These various widths represent approximately 70 to 95 percent of the potential source area for large woody debris recruitment, respectively. The prescriptions described in the rules have been designed to meet the desired future conditions on average across the landscape. However, the prescriptions are based upon some assumptions about stand condition and growth and may not ideally address all site conditions. Monitoring is in place to evaluate the adequacy of the prescriptions and the assumptions upon which they were developed.
Forest roads represent a high risk for increased sediment delivery to streams.
However, many roads built prior to current practices retain higher risks for sediment delivery than would be the case if the roads had been constructed under the current standards of design. Emphasis of this effort will be given to roads within core area watersheds. Measures related to core area protection are described briefly below. OFIC members will voluntarily change the ratio of 50 percent conifer and 50 percent hardwood, to 75 percent conifer and 25 percent hardwood when requested on a site-specific basis.
