2 Relational Databases (MS Access)  Data Management  Modeling  Input/Output GIS(ArcGIS)  Spatial Relationships  Mapping Results  Visualizatioin/Interaction GIS(ArcGIS)  Spatial Relationships  Mapping Results  Visualizatioin/Interaction  Capture & Organize Information about 8 Elements  Detailed  Comprehensive  Spatially Explicit  Define relationships between elements  Use models to allow evaluation and prioritization

4 Sources: TDEC Natural Heritage TVA Heritage TWRA Non-Game Inventory Program TWRA Aquatic Database (TADS) Scientific Collection Permits Various Others – BISON, etc.

5 Species Conservation Priority Score: Weight by Rarity/Legal Status G Rank (40 pts) S Rank (40 pts) Federal Status (10 pts) TN State Status (10 pts) Exponential (G1 = 40, G2 = 20, G3 = 10, etc) Viability/Confidence Scores for Observations Last Observation Date (old records, less points) Heritage EO Ranks Where Available

6 Terrestrial Occurrences Linked to 700-acre hexagon clusters called rosettes Aquatic Occurrences Linked to NHDPlus Flowlines & Associated Catchments Subterranean Observations Linked to Cave Systems Cave system entrances linked to 100-acre hexagons

16 Assume mapped semi-natural habitat restored to dominant matrix forest type within subregion Use restored habitat preference scores (P) for existing GCN occurrences in/around semi-natural habitat Net Restoration Priority = Restored Score – Current Semi-natural Score  If had antecedent or other potential restoration habitat map, could use to dictate restoration scenario
