Assessment of the Significance of Predators on the Endangered Waterbird Population at the Kanaha Pond Wildlife Sanctuary, Kahului, Maui
(Dr. Renate Gassmann-Duvall; October 1994)

Assessment of the Significance of Predators on the Endangered Waterbird Population at the Kanaha Pond Wildlife Sanctuary, Kahului, Maui addresses the effectiveness of mechanical live-catch trapping on reducing populations of six species of mammalian predators at the Kanaha Pond Wildlife Sanctuary (KPWS) on the Island of Maui, Hawaii. The report was prepared by Dr. Renate Gassmann-Duvall, Ph.D., D.V.M., of The Conservation Council for Hawaii for the U.S. Fish and Wildlife Service under Cooperative Agreement No. 14-48-0001-93614.

The Kanaha Pond Wildlife Sanctuary (KPWS) is an exemplary location to address both mammalian predator management and Hawaiian waterbird management issues. It is an officially protected sanctuary which contains at least three endangered Hawaiian waterbird species and an abundance of alien mammalian predators. The study was conducted from 1 March to 15 May, 1994, a period which coincides with the approximate peak of nest-building, egglaying, and incubation by resident Hawaiian stilts and coots. Results of this study were utilized in the development of a long-term trapping strategy for KPWS by the author.
