Hakalau Forest National Wildlife Refuge
- Summary:
- Since removing feral pigs, (Sus scrofa), can have substantial benefits of the native Hawaiian avifauna, there were six objectives of this study as follows: 1) to summarize necropsy data on the age and sex composition and reproduction rates of the feral pig, 2) to reconstruct population dynamics in a management unit based on the ages of the removed pigs, 3) to summarize survey of feral pig activity, 4) to relate the standing population within a management unit to activity surveys in a predictive model of feral pig density, 5) to apply the predictive model to estimate densities of feral pigs in other management units, and 6) to evaluate the efficacy of several control methods. This was done in an effort to reduce the breeding habitats of malaria-carrying mosquitoes in an effort to increase the recovery of native vegetation. The area used in this study was within the 750 - 2000 m elevation of the Hakalau National Wildlife Refuge, a tropical montane rainforest that is located on the windward slope of the Mauna Kea volcano on the island of Hawaii.
