Portions of Parker Ranch contain or border valuable natural treasures, such as the Kohala Watershed, with examples of some of the most spectacular ecosystems in Hawai‘i. Located in the Kehena region of the Ranch, the eastern portion of the Kohala Watershed wraps around the back of Pololū Valley and abuts Honokāne Valley, which supports substantial cover of native trees and a broad diversity of native plants.
Another significant environmental area is Waipunalei, on the eastern end of the Ranch. It borders the Hilo Forest Reserve and the US Forest Service Experimental Forest in Laupahoehoe, home to important native plants and wildlife.
In addition, remnants of the Waimea Field system can also be seen on the Ranch. The upper edges reach onto Parker Ranch along Kohala Mountain Road and up to the 2800’ elevation level.
Parker Ranch loves and cherishes these areas and they are what they are today because of our management practices.
