| Abstract/Description or Keywords | The size distribution (texture) of the sediments that make up the bed of a stream channel are an important component of fish habitat. Efficient and accurate characterization of bed material in the steep, forested watersheds typical of British Columbia’s coastal mountains requires a clear understanding of the nature and causes of textural variations. The accompanying poster describes the background, methods, and results of a study of bed material texture in two creeks on the Queen Charlotte Islands. On the basis of this study, sampling guidelines for habitat assessment and monitoring purposes are presented. The key recommendations, and some additional discussion of sampling techniques, are presented on this handout. Recommendation 1: There is no simple relation between the full size distribution of subsurface material and the sizes visible on the surface. The former is largely responsible for redd-gravel permeability; the latter may limit the ability of some species to construct redds. Both populations should be sampled independently. |
