Title
Stream Substrate composition after fire in some Bitterroot Watersheds
Abstract
Random sampling of particle composition of instream substrate can help quantify the effects of fire on watersheds. Using the Wolman pebble count, hydrologists of the Bitterroot National Forest monitored five East Fork Bitterroot River sites over eight years and documented substrate particle composition. In each site a minimum of 100 samples were taken, intermediate axes were measured and particle sizes were determined. Percentiles were calculated in the Forest Service database in order to determine statistical accuracy of the data. Observations indicated little change in composition in the sampled watersheds during the study period.
