Service Description: This feature class represents the historic (1980) scenario for bull trout, derived from the Climate Shield fish distribution models. These models provide stream-specific probabilistic predictions about the occurrence of juvenile bull trout and cutthroat trout in association with three different scenarios for climate change and brook trout invasions. These datasets indicate all potential cold-water habitats 500 cold-water streams. The stream centerlines were based on the National Hydrography Dataset (NHD) but were modified for purposes of modeling and cross-walking to other datasets.

Layers: Description: Map service on the www depicting Climate Shield data. Climate Shield builds off of NorWeST modeled scenarios. Climate Shield data allows analysis of temperature impacts on cutthroat trout and bull trout. This data is well suited for land management priorities and stream restoration activities. 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 greater than 10% are resistant to brook trout invasions, probabilities in those habitats do not change relative to brook trout prevalence.
