Columbia Basin Historical Ecology Project Data
Basin wide assessments of historical habitat potential in the Columbia basin.
The Columbia Basin Historical Ecology Project consists of basin-wide assessments of historical habitat potential and current habitat condition to guide recovery efforts for endangered salmon. Associated datasets and model outputs include attributed stream networks, main stem and side channel habitat predictions, reference channel type predictions, and pre-settlement riparian vegetation predictions.
Our datasets are based on the U.S. National Hydrography Dataset (NHD) and the Canadian Watershed Atlas. We have model results and stream attributes built upon the 1:100K and the newer 1:24k NHD versions. Because of the network processing required to run our models we were not able to retain NHD reach identifiers but our layers can be associated with other datasets using spatial joins.
