Data product for "Anticipated climate warming effects on Bull Trout habitats and populations across the Interior Columbia River Basin"

This archive contains the data necessary to complete the general processing steps as outlined in the associated publication, Rieman et al. (2007). These steps include: 1) summarize site level observations of bull trout to identify lower elevation limits of natal habitats across the Columbia Basin; 2) summarize mean annual air temperatures for weather stations across the same area; 3) regress each set of observations against longitude and latitude (and elevation in the case of temperature) and compared the coefficients in the two regression models to consider whether climate could explain bull trout distributions; 4) use GIS to map the area and size distributions of thermally suitable habitat patches based on predicted distribution limits; and 5) use the GIS to explore changes in distributions, area, and number of suitable habitat patches of bull trout by elevating lower distribution limits, consistent with three levels of warming that could be realized as a result of future air temperature increases. The analysis was constrained to the potential range of bull trout in the basin following Rieman et al. (1997). Suitable patches were considered to be the area of a watershed above the predicted lower distribution limit of small (To determine if climate influences bull trout populations, explore the implications of climate warming for this species, and estimate bull trout habitat response to a range of warming climate scenarios.Original metadata date was 04/09/2009.
