The Vegetation and Environment of the Crater District of Haleakala National Park

Abstract

A vegetation map of the Crater District of Haleakala National Park was produced at a scale of I : 24,000, which can be used as an overlay of the U.S. Geological Survey I : 24,000 topographic quadrangle maps. Fifty-three structural-floristic communities, which were grouped into four structural vegetation types, were mapped. Areas were calculated for each community using an electronic planimeter. Topographic vegetation profiles were constructed that show changes in vegetation types in relation to climatic gradients. Correlations were observed between certain substrates and community types. Phytosociological analysis of releve data by the synthesis table technique and the dendrograph technique resulted in ecologically meaningful groupings of the sample stands.
