Phenology, reproductive potential, seed dispersal and predation, and seedling establishment of three invasive plant species in a Hawaiian rain forest
After rain forest of Haleakala National Park was fenced in the late 1980s, native vegetation responded vigorously yet three problematic plant invaders (Clidemia hirta, Hedychium gardnerianum, and Psidium cattleianum) continued to spread unabated and became of great concern to Park managers. This contribution provides a quantitative assessment of crucial life history junctures (quantitative phenology, reproductive potential, seed dispersal, seed predation, seedling establishment) to assist Haleakala NP and other managers of Hawaiian rain forests. It also provides detailed information for potentially identifying key characteristics in prevention, rapid response, and prioritization of incoming invasive species. (This document is the 2004 Ph.D. dissertation of Dr. Arthur C. Medeiros for the Department of Zoology at the University of Hawaii.)
