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

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

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
