Species Conservation Program: Species Evaluation Index — Ferns and Fern Allies

Species Conservation Project logo

 

Species occurrence on National Forest System units as portrayed by these tables is based on limited information available to evaluators at the time of preparation of species evaluations. Because these evaluations were intended to be sketches and not exhaustive, and because distribution information for many species is inadequate, the accuracy of these location tables cannot be ensured. Therefore, users must assume the responsibility of verifying that this information is accurate for individual forests.
