Predictable risk to native plants in biological control of weeds in Hawaii View info about Adobe Acrobat PDF format
This analysis examines the use of non-target native plants in Hawaii resulting from biological control projects on target weeds with close relatives compared with projects on target weeds that lack close relatives. Target weeds with close relatives are riskier targets for biological control than are weeds without close relatives in Hawaii. The two projects conducted against weeds with close relatives resulted in non-target use of native species; four of the five insect species established in these projects now use native plant species as hosts.

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.
