Riparian Climate-Corridor (RCC) Index:WGA/LCC Riparian Mapping Project mapped riparian condition and climate adaptation potential.
Data is shown as the RCC Index for the top 2 quintiles (60th percentile) averaged within each 6th field HUC.These layers were produced as part of the WGA/LCC Riparian Mapping Project, which identified riparian location, condition, and climate adaptation potential, for the Pacific Northwest, USA. These layers identify potential riparian areas (i.e., near-stream valley bottoms; Theobald et al. 2013) that span large temperature gradients, have high canopy cover, low solar insolation, and low levels of human modification – characteristics expected to facilitate climate-induced species range shifts and provide micro-climatic refugia from warming. Detailed description of the project rationale, methods, and resulting layers may be found in the citations.
The index is averaged over the HUC6 watersheds and colored blue to represent the 60th percentile of the RCC Index.
