Lehua Island Ecosystem Restoration Project


  1. Update 6-18-18 : The LIERP deploys rat detecting dogs to Lehua Island to try and find few remaining rats. Read full story here.

  2. Update 3-27-18 : Ongoing monitoring efforts on Lehua Island since September have turned up less than ten sightings of rats on cameras and other monitoring devices installed on the island. This is an indication of very low numbers of rats on Lehua. Targeted efforts to  eliminate these rats (traps, bait boxes, etc.) have been deployed and more will be deployed soon. Birds are continuing to do well with no signs of rat attacks on eggs, chicks, or adults on nests. Plants that were previously consumed by rats are persisting. Many of the plants continue to be flush with green leaves. Further monitoring will occur on a regular basis to determine the status of Lehua Island.

    This is just one of hundreds of healthy wedge-tailed shearwater chicks that had continued to to grow on Lehua Island free from attack by rats as of November 2017.

    Post-application monitoring of Lehua Island will continue for several months to determine the success of the rat eradication effort and environmental response. Check back to this website to receive regular updates on observations and results.

Lehua Island is a 284-acre island located three-fourths of a mile off the northern shore of Niihau (a privately owned 46,080-acre island). Lehua is a state-designated seabird sanctuary managed by the Hawaii Department of Land and Natural Resources (DLNR) and federally owned by the U.S. Coast Guard (USCG). Lehua is one of Hawaii’s most important seabird colonies because of its size and height above sea level.  It also offers a unique opportunity for restoring an island ecosystem.

DLNR Division of Forestry and Wildlife (DOFAW), in conjunction with federal sponsor United States Fish and Wildlife Service (USFWS), technical partner Island Conservation (IC), and the cooperating members of the Lehua Island Restoration Steering Committee (LIRSC) are working together toward the eradication of rats from Lehua Island so further restoration efforts can move forward in the future.
