Haleakala National Park resources basic inventory: mosses

Abstract

As the result of three summers' field work in the Crater District of Haleakala National Park, island of Maui, sponsored by the National Park Service through the Cooperative National Park Resources Studies Unit at the University of Hawaii, 128 moss species and varieties were collected and identified. The Park is now known to be the only Hawaiian locality for at least 25 taxa, and the only Maui locality for an additional 38. A large number of rare species were also collected. The general ecology of the Crater District and the mosses associated with the seven proposed vegetation types are discussed. Also discussed are the phytogeography as well as the degree of endemism of Haleakala's mosses.
