Description: The GIS (Geographic Information System) analysis used during the production of this plan, which influenced the assessment, used the 29 input layers. These layers are associated with each key issue, threat, value or collaborative opportunity, which are also tied to each of the three USFS-SPF national themes and Cohesive Strategy Tenets within the Strategies section of this document. GIS was used to overlay and analyze each of the weighted layers to produce a cumulative key issues and threats concentration map. The concentration levels were classified into five relative categories. The areas shown in purple represent the highest priority areas and represent geographic areas where data layers created the most overlap. All urban and community areas were classified outside of the analysis as high because of the need to manage urban forests and wildfire hazards within and around these areas to protect human life and enhance local economies as a priority. Riparian and wetland areas were also classified as high outside of the analysis because of their importance in serving basic needs for human and wildlife populations and their vital support of economic activities in the state.
