<br />I <br />Substrate composition. Substrate composition was visually estimated at all <br />verticals both wet and dry. Substrate was denoted for the following categories: <br />P1, <br /> Grass/terrestrial vegetation <br /> Aquatic vegetation <br /> Silt <br />' Sand <br /> Small gravel (0.25 - 1.0 inch) <br />' Large Gravel (>1.0 - 3.0 inch) <br /> Cobble (>3.0 - 10.0 inch) <br /> Boulder (>I 0.0 inch) <br /> Bedrock <br /> <br /> The substrate was categorized by dominant and subdominant size class. This <br /> provided the information required for the salmonid habitat suitability criteria. <br /> This method of substrate categorization can be adapted to most of the usual <br /> substrate codes in the existing habitat suitability criteria for salmonid species. <br /> C <br />C <br />i <br />ll <br /> over. <br />over was v <br />sua <br />y estimated by percentage at each vertical. We used the <br /> following cover types: <br /> Velocity Refuge - any instream object that provides a velocity refuge for <br />h <br />i <br />f <br /> t <br />e spec <br />es o <br />interest. This could include objects such as boulders, root <br /> wads, large woody debris or other such objects. <br /> Visual Isolation - any object that provides visual isolation for the species <br /> of interest such as overhanging vegetation, undercut banks, or other such <br /> items. <br /> <br />Draft 2001 Task Summary Report Page 7 <br />Miller Ecological Consultants, Inc.
