Service Description: Main Attributes:1. NorWeST: The river basin corresponding to the area where NorWeST stream temperature scenarios were previously developed.2. PATCH_ID: Unique identifier for one cold-water habitat within a NorWeST unit. 3. MeanTempC: MeanTempC was used in the cutthroat trout model and was the mean August temperature across all 1-km sections constituting a cold-water habitat. 4. Slope%: Stream slope was represented as the average value across all reaches within a cold-water habitat.5. StreamKM: Habitat size was represented as the channel length of each cold-water habitat. The upstream extent of a habitat was delimited at 15% and VIC model flow predictions of summer flows > 0.0057 m3/s.6. CT__0%BKT ? CT_100%: These five fields are probabilities of juvenile cutthroat trout occurrence within a cold-water habitat based on the prevalence of brook trout at 0%, 25%, 50%, 75%, or 100% of the sites within a habitat. The probabilities were predicted using the Climate Shield native trout models developed from known species occurrence in >500 cold-water streams. This information can be used to assess how vulnerable a native trout population would be to a brook trout invasion or whether a native trout population would persist in the absence of brook trout. Note that because native trout populations in habitats with slopes >10% are resistant to brook trout invasions, probabilities in those habitats do not change relative to brook trout prevalence.
