Relative Conservation “Value” based upon Natural History Collections
Normalized Abundance (= # of Localities)

       Relative Endemism/Range-Size

Time Elapsed Since Most Recent Collection
In summary, the primary data documenting biodiversity constitute essential information with which to evaluate relative conservation status among species.  One could calculate a relative conservation “value” based solely upon specimen data that incorporated normalized abundance, i.e., the # of total localities, a measure of relative endemism or range-size rarity, and the time elapsed since the most recent collection.
