Introduction and History
1860’s - 1960:Various goat, sheep, and cattle grazing in Pu‘u Wa‘awa‘a, cattle grazing in Pu‘u Anahulu
1960: 40 year cattle grazing lease signed to Dillingham Ranch, Inc. for 105,000 acres
1972: Lease signed over to F. Newell Bohnett
1984: 84,000 acres in Pu‘u Anahulu and part of Pu‘u Wa‘awa‘a revoked due to illegal koa harvesting,
3,806 acres of this set aside to be made into a Forest Bird Sanctuary.
2000: Bohnett lease ends

“Even as grazing causes gradual declines in forest cover, however, it protects forests from rapid loss to destructive fires by reducing the ability of grass fuels to carry fire.
Grazing in drier areas reduces the risk of fire not only by controlling the accumulation of fuels, but also by controlling the spread of more flammable grass species.” (i.e. fountain
grass)

THREAT: Fire
Mitigation: Cattle/Ungulate Grazing
Cattle Grazing: DOFAW issues 3 annual grazing permits in PWW for fuel control. In the circled area there are currently ~1,000 head of cattle. We are exploring the possibility of moving
cattle into Puu Anahulu and implementing proper stocking rates in PWW Makai. Completed a $5 million water improvement CIP project which will help us increase the stocking rate below
the highway.

Current Strategies: Ungulate Removal
17
Fence ~8,000 acres of native forest (~50% of remaining native habitat). 80% of the known endangered plants are located in these fences. Remove all ungulates from within the fences.
Mitigation for endangered plants taken outside of fences through outplanting and habitat restoration.
