Appendix Q
Addendum 1
As a default, the ANALYZE tab will pre-select threat categories based on ecoregion. Information about bioenergy scenarios can be found in two research papers published in 2016 and written by scientists with the USGS and N.C. Cooperative Fish and Wildlife Research Unit at N.C. State University.
• Threat categories for Sea Level Rise apply to the Coastal Plain ecoregion only.
• Threat categories for Energy Development Triassic Basin apply to the Piedmont and Sandhills ecoregions; the Wind Energy threat applies to all ecoregions.
Each threat has been assigned a default lower limit of threat severity. Each default limit is based on a 0 to 1.0 scale. Clickin g on “ detail s” next to the threat name opens a graph and scale depicting default thresholds. In the Figure 8 example, the default limit for loss
Figure 8. Data Thresholds
of Open habitat has been set to a threshold level of 0.8. A default threat severity of 0.80 is calculated as 10.31% Open Habitat loss in the AOI. • Interpretation: when the model predicts loss of Open Habitat is 10.31% or greater, this threat is reported as occurring in the AOI. When the predicted loss is less than the threshold limit, the threat is not reported as occurring in the AOI. The threshold limits can be adjusted by the user. Setting a lower limit allows the user to review whether a lower threat severity will have a more (or less) severe impact to the type of habitat targeted in the analysis.
Each threat has a PREVIEW button that displays results of changing the severity limit. After an analysis is configured, the user can view the resulting threat count map and/or a comprehensive report detailing threat occurrence and severity.
