TN Plan Database Concept
Capture & Organize Information about 8 Elements Detailed Comprehensive Spatially Explicit
Define relationships between elements
Use models to allow evaluation and prioritization
Observations of Conservation Target Species
Sources:• TDEC Natural Heritage• TVA Heritage• TWRA Non-Game Inventory Program• TWRA Aquatic Database (TADS)• Scientific Collection Permits• Various Others – BISON, etc.

Prioritization and Weighting of GCN Species Observations
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
Linking GCN Species Observations to Habitats
• 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

Evaluating Terrestrial Habitat Restoration Priorities
• 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
