Koa loopers

Koa looper moth

Koa looper moth defoliation is now clearly visible from the saddle road, apparently moving further south, although there is no indication that the effects are moving upslope to higher elevation koa stands at present. Thus far only the very lowest elevations at HFNWR’s Maulua Unit have been impacted by the defoliation event.

What's Happening at the Refuge

  • Cancelled - Spring Open House

    Iiwi in ClarmontiaApril 16, 2016

    With regret, we have decided to cancel our planned Spring Open House at Hakalau Forest National Wildlife Refuge (HFNWR), originally scheduled for April 16, 2016​. As new information about Rapid Ohia Death (ROD) is coming out all the time and ​more is learned about the extent of its occurrence and the probable means of spreading of this serious disease, we want to take every precaution to minimize the risk of unwittingly spreading the fungus while conducting an otherwise very beneficial and educational event for the public​. ​ ROD has not been confirmed on the Refuge at this point​, but recent observations in the area and discussions with our research partners at U.S. Department of Agriculture and University of Hawai'i have heightened the level of concern for Hakalau Forest.​ Additional sampling efforts have been undertaken as a precaution. ​ At this time, there is no plan to reschedule the Spring Open House.

  • Lend a Helping Hand

    Reforestation efforts began in 1987 and have continued into the Present. Most of the reforestation can be attributed to assistance by local, national, and international volunteer groups. They have contributed thousands of hours to reforestation and to help in the recovery of Hawai`i's native forest habitats.
