When Exotic Fish are Away, Hawaiian Waterbirds Will Stay

Human development, agriculture, and rising seas are encroaching upon coastal wetland ecosystems and causing visible and profound changes. Another threat, less obvious to the casual observer, lurks beneath the water’s surface: non-native fish. Researchers with the U.S. Forest Service Pacific Southwest Research Station’s Institute of Pacific Islands Forestry are studying the threats posed by exotic fish species and working with partners to battle the gilled invaders.

Hawaiian stilt by stream

Nearly a decade ago Rich MacKenzie, Forest Service aquatic ecologist and NREM Affiliate Graduate Faculty,  realized that, due to a lack of data, no one really knew the scope of the problem. Between 2007 and 2010, he and Dr. Greg Bruland (former NREM faculty, and current Affiliate Graduate Faculty), collaborated on a project that took stock of 40 wetlands across Hawaii’s five main islands to evaluate water quality and the overall condition of these wetlands, including their aquatic wildlife makeup.
