This is part of a connectivity modeling and mapping project for the Sacramento Valley that maps connectivity for several focal species, structural connectivity, and their combination.
This layer and its three related layers, below, are the answer to the common request by stakeholders and decision-makers: a single, best estimate, connectivity map for the biodiversity of a region. This "Top Values" layer is here primarily for easy visualization, but has linkage spur map artifacts for about 2% of the study area, and hence is termed Beta. If funds are provided, then the proposed improvements can be implemented. Currently, if a single layer is needed, it is best to use the full coverage of "Structural and Focal Species Connectivity Combination" dataset, for quantitative and decision-making purposes, not this one.
The focal species analyzed are Taxidea taxus (American badger), Lynx rufus (bobcat), Odocoileus hemionus (mule deer), and Cervus elaphus (tule elk). Structural connectivity, also known as naturalness connectivity, was mapped in four ways: using the lens of a small or large animal, and for each, one that prefers tree canopy cover versus one that is ambivalent about tree canopy cover. All eight analyses considered climate change in mapping their linkages, they also included pinchpoint, linkage priority, and core priority analyses. The core area priority analysis was weighted high for this particular application, but may be too high for your decision at hand and should be considered accordingly.
