[Concept] Total floristic diversity [Criterion] 
The sum of all species observed in the inspector's sample—both woody and herbaceous species. Other than the criterion for woody species (above), no minimum for total floristic diversity. Herbaceous species noted in sampling—often as ground cover—but not critical in attaining certification.
