Title: Coho Intrinsic Potential
Feature Count: 0
Feature Type: Line
Abstract: Information on estimating the quality and extent of historical habitat is needed for ongoing efforts to conserve and eventually recover protected populations of Pacific salmonids. Because georeferenced spatial data on habitat and fish distribution at the regional scale are lacking, we requested that NOAA implement a GIS approach in modeling the intrinsic potential (IP) of stream reaches to support juvenile coho salmon. The IP model uses geomorphic and hydrological attributes to estimate the latent potential of stream reaches to provide favorable habitat characteristics for spawning and rearing. Indices for the model are derived from a DEM and precipitation data. Thus, the model predicts patterns of relative productive potential expected in the absence of human disturbances, as related through the input data. The stream lines used as the basis for the IP geometry are based on King County's watercourse dataset, which has omission and spatial accuracy issues.
Purpose: This data set provides an estimate to the spatial distribution of potential habitat for coho salmon in King County.

_AboveTotalNaturalBarrier_Tracks whether the selected segment is above a total natural barrier.
YesSelected segment is above a total natural barrier
NoSelected segment is not above a total natural barrier
_AllUSSegmentsZero_AllUSSegmentsZero tracks if all segments upstream of the selected segment have an intrinsic potential score of 0. This field is used to limit the segments that are included in the overall upstream habitat quantity distance, value and score fields.
