From ridge to reef—linking erosion and changing watersheds to impacts on the coral reef ecosystems of Hawai‘i and the Pacific Ocean
Coral reef ecosystems are threatened by unprecedented watershed changes in the United States and worldwide. These ecosystems sustain fishing and tourism industries essential to the economic survival of many communities. Sediment, nutrients, and pollutants from watersheds are increasingly transported to coastal waters, where these contaminants...Stock, Jonathan D.; Cochran, Susan A.; Field, Michael E.; Jacobi, James D.; Tribble, Gordon
Wild sheep and deer in Hawai'i: a threat to fragile ecosystems
The unique native flora of the Hawaiian Islands, which evolved in the absence of ungulates (grazing animals), is highly vulnerable to damage by trampling and browsing. Wild ungulates introduced into Hawai'i in the past 150 years, including mouflon, axis deer, and mule deer, have severely harmed the native flora. Control measures used against feral...Hess, Steven C.
Hawaiian Duck's Future Threatened by Feral Mallards
Nearly 70 percent of Hawaii's native bird species are found nowhere else on Earth, and many of these species are declining or in danger of extinction. Although the Hawaiian Islands were once home to a remarkable diversity of waterfowl, only three species remain-the Hawaiian Goose (Nene), Laysan Duck, and Hawaiian Duck (Koloa maoli)-all Federally...Uyehara, Kimberly J.; Engilis, Andrew; Reynolds, Michelle
Palila Restoration: Lessons from Long-term Research
BACKGROUND The palila (Loxioides bailleui) is a member of the Hawaiian honeycreeper family of birds (Drepanidinae), which is renowned for the profusion of species - many with bizarre bills and specialized feeding habits - that radiated from a single ancestral type. Most of the 57 or so honeycreeper species are extinct, and the palila is...
Restoration of Native Hawaiian Dryland Forest at Auwahi, Maui
BACKGROUND The powerful volcanoes that formed the high islands of the Hawaiian archipelago block northeasterly tradewinds, creating wet, windward rain forests and much drier, leeward forests. Dryland forests in Hawai'i receive only about 20 inches of rain a year. However, the trees in these forests intercept fog and increase ground moisture...Medieros, Arthur C.; vonAllmen, Erica
Hawaii Forest Bird Interagency Database Project: Collecting, Understanding, and Sharing Population Data on Hawaiian Forest Birds
The forest birds of the Hawaiian Islands are distinguished by the diversity of endemic forms derived from a small number of ancestral colonists. However, the avifauna has been decimated by human activities both before and after Western contact. At least 71 species or subspecies disappeared before the arrival of Capt. James Cook in 1778, and...Pratt, Thane K.; Woodworth, Bethany L.; Camp, Richard J.; Gorresen, P. Marcos

Feral Cats: Too Long a Threat to Hawaiian Wildlife
BACKGROUND Domestic cats (Felis catus) were first brought to Hawai`i aboard sailing ships of European explorers and colonists. The job of these predators was to control mice and rats on the ships during the long voyages. As in other places, cats were taken in and adopted by the families of Hawai`i and soon became household pets known as popoki...Hess, Steven C.; Banko, Paul C.
Feral Pigs, Introduced Mosquitoes, and the Decline of Hawai'i's Native Birds
The introduction of mosquitoes, avian pox, and avian malaria to the Hawaiian Islands has had a profound effect on the geographical distribution and population number of highly susceptible Hawaiian honeycreepers, and likely contributed to the extinction of several species. While the mosquito vector (disease-carrier) is most closely associated with...LaPointe, Dennis A.
Biocomplexity of introduced avian diseases in Hawai`i: threats to biodiversity of native forest ecosystemsWoodworth, Bethany L.; Atkinson, Carter T.; Samuel, Michael D.; LaPointe, Dennis A.; Banko, Paul C.; Ahumada, Jorge A.
Translocation of Endangered Laysan Ducks to Midway Atoll National Wildlife Refuge (2004-5)
BACKGROUND Island ecosystems throughout the Pacific have undergone catastrophic species loss, largely due to the effects of alien or non-native species. Rats, in particular, pose significant threats to native species. In Hawai`i, the appearance of rats (which are not native to Hawai`i) in the subfossil record coincides with the disappearance of...Reynolds, Michelle
Ecology and diagnosis of introduced avian malaria in Hawaiian forest birds
Avian malaria is a disease caused by species of protozoan parasites (Plasmodium) that infect birds. Related species commonly infect reptiles, birds and mammals in tropical and temperate regions of the world. Transmitted by mosquitoes, the parasites spend part of their lives in the red blood cells of birds (Figure 1). Avian malaria is common in...Atkinson, Carter T.
