Coastal wetlands the world over are known for harboring an impressive array of plants and animals. In the Pacific Islands, wetlands not only provide habitat for many unique species, including some threatened and endangered waterbirds, but also support communities of people who rely on these special places for food and other essentials.
Human development, agriculture, and rising seas are encroaching upon these 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.
