Mamane Sophora Chrysophylla Feral ungulates Palila Mauna Kea Forest Reserve Kaohe Game Management Area

Summary:

This document describes how feral sheep and other ungulates adversely affected the mamane (Sophora chrysophylla) forest. It also describes how the continued decimation of the mamane overstory, (through the death of old trees and its failure to regenerate itself), became a significant threat to the Palila (Psittirostra bailleui), an endangered and endemic Hawaiian bird that is restricted to the mamane forest of Mauna Kea, on the island of Hawaii. As a result, this study was done in an effort to determine how the changes in tree canopy cover that occurred within the Mauna Kea Forest Reserve, the Kaohe Game Management Area, and the adjacent Parker Ranch affected the Palila habitat from 1954 - 1975 and if/how the mamane forest will regenerate itself should feral sheep be removed.
