The He‘eia National Estuarine Research Reserve encompasses 1,385 acres on windward O‘ahu with multiple unique aquatic ecosystems where federal, state, and community-based partners contribute to the restoration and study of watershed and estuary characteristics and Indigenous aquaculture. The Reserve includes He‘eia Stream, coral reefs, sand flats, an ancient Hawaiian fishpond, as well as traditional agricultural and heritage lands. It is home to the endangered Hawaiian stilt, moorhen, coot, and duck. The University of Hawai‘i at Mānoa’s Hawai‘i Institute of Marine Biology is the lead partner with an administrative center located on Moku O Lo‘e (Coconut Island) within the Reserve.
