Under Scenario A, we used existing GAP Status 1 protected areas (highest protection levels) as habitat nodes. A size threshold (1,000 ha) was applied in order to reduce and normalize the number of nodes being evaluated among all three scenarios. For this region, these include many areas of the Adirondack State Park, Baxter State Park, and national parks in both Canada and the U.S. (N = 95). Under this scenario, we assume that we are evaluating connectivity for those species having their most significant population sources in the most protected areas. Under Scenario B, we used the regional Last of the Wild (Sanderson et al., 2002) representing areas of lowest human-caused landscape transformation (i.e., Human Footprint scores less than 10) as habitat nodes. No size threshold was set for this dataset as the regional Last of the Wild dataset included the fewest number of patches (N = 120). Under this scenario, we assume that we are evaluating connectivity for those species most sensitive to human-caused landscape transformation. Under Scenario C, we used potential source population patches for Marten (Martes Americana) (Carroll, 2003). Under this scenario, we assume that we are evaluating connectivity for a potential focal species which may or may not have populations in these areas which are comprised of specific habitat requirements. A size threshold (1,000 ha) was again applied to the input patches of this scenario in order to normalize the number of patches found within this scenario with those of the others (N = 105). We used the Human Footprint values as a cost surface for those species most sensitive to human-caused landscape transformation (Woolmer et al., 2008). Because the Human Footprint dataset is scaled from 0 (most wild, least influenced by human activity) to 100 (least wild, most impacted by human activity), we reclassified these values into the scale range accepted by the tool (0-1). Human Footprint values of 100 became 0 for the permeability value associated with the cost surface, and Human Footprint values of 0 became 1 (most permeable). We assigned no aggregation factor (i.e., value of "1") so that the original resolution (90 m) would be maintained. We accepted the default links Qn value (10) because we did not want to be either overly restrictive or liberal in our selection of potential linkages. The links Qn value represents the lowest percentile allocation values from which linkages are derived. Allocation zones were then grown from the source patches across the cost surface until they met, forming allocation boundaries. Based on patch-to-patch distance, cost-distance values for selected cells served as the midpoints for the first set of initial linkages. Within each allocation zone, cells exhibiting values less than the user-defined links Qn value were removed, which results in the final, proposed corridor.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Purpose:</I></DT> <PRE ID="original">This analysis is a first-pass at evaluating ecological connectivity for the Northern Appalachian/Acadian ecoregion. It was conducted as part of Ryan M. Perkl's doctoral research and not specifically for 2C1Forest, but using 2C1Forest data as available on this atlas. Our intention is not that this is a prescription or landscape design, but a plausible scenario based on our assumptions for large swaths of the ecoregion that might serve a connectivity function.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Supplemental_Information:</I></DT> <PRE ID="original">Please refer to Baldwin, R.F., R.M.
