6.5.1.3 Threat Risk Assessment DST
A risk assessment is the process by which users identify threats, and analyze and evaluate risk associated with threats. The N.C. Wildlife Habitat Threat Risk Assessment (TRA) tool is a spatially explicit DST that uses modeling to predict future probability that specific threats will occur relative to terrestrial and aquatic habitats — specifically climate change and urbanization. This DST includes other types of threats that are not projected in time but whose occurrence on the landscape can create impacts or exacerbate other types of impacts. The DST identifies threats, enumerates them (threat count), estimates occurrence and provides a qualitative measure of severity within a user-defined area of interest (AOI).
6.5.1.4 Use and Results
The DSTs allow users to explore individual threat/risk components in a spatial environment as well as combine and weigh components in user-defined configurations to highlight specific threats and develop specific scenarios of future trends. The Tool supports statewide habitat acquisition and management decisions by projecting future probability of occurrence of specific threats relative to terrestrial and aquatic habitats — specifically climate change and urbanization. Results from DST analyses are presented on a digital map using a 12-digit Hydrologic Unit Code (HUC) classification system for sub-watershed drainage areas. Information about the HUC classification system is available from the USGS website https://water.usgs.gov/GIS/huc.html. A user guide for the tool is provided in Appendix Q.
