When Exotic Fish are Away, Hawaiian Waterbirds Will Stay

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.

Preserving an Ancient Hawaiian Treasure

It’s National Preservation Month, and people all over the country are participating in events to enrich and preserve the treasures within their communities that make them special.

Staff from the U.S. Forest Service’s Pacific Southwest Research Station recently helped to restore an ancient Hawaiian fishpond in Kīholo, Hawaii, that has a rich history and tradition of providing a sustainable food source for the surrounding communities on the Big Island. Working in collaboration with The Nature Conservancy and Hui Aloha Kīholo, Station staff from the Institute of Pacific Islands Forestry cleared and hauled debris from the fishpond perimeter in order to reduce the accumulation of sediments caused by overhanging non-native plants, which improved foraging habitat for native fish and turtles. The group also replanted culturally and ecologically appropriate native species, restored habitat for rare invertebrate species, removed invasive weeds, and participated in native plant care within an area surrounding a nearby anchialine pool, which will be used as a nursery for future restoration activities.
