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

  • Closed - Public Access Area

    Maulua Public Access SignJune 27, 2016

    With regret, we have decided to close our public access area, the Upper Maulua Unit, to self-guided activities. As new information about Rapid ʻŌhiʻa 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 activity​. ​ 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. ​More information about Rapid ʻŌhiʻa Death can be found at:
  • 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.
