Hawai'i - Laupahoehoe Experimental Forest

For this latest research project, the Southwest Watershed Science Team went truly southwest - to the Laupāhoehoe Experimental Forest (EF) on the Isle of Hawai'i. The 12,343-acre Laupāhoehoe EF in North Hilo was formally established on state land when a federal register notice (72 F.R. 13740) was published, on March 23, 2007, in which the Secretary of Agriculture designated the units of the Hawai'i Experimental Tropical Forest. Research in the EF will focus on tropical forestry, hydrology, conservation biology, invasive species control, native forest restoration and ecology, and sustainable commercial timber practices, along with education, training, outreach and preservation of cultural values. Because of the long standing watershed related research the Rocky Mountain Research Station and its predecessors have conducted in the southwestern U.S., the Institute for Pacific Islands Forestry, which is part of the Pacific Southwestern Research Station, asked the RMRS AWAE Southwest Watershed Science team for assistance in the initial phase of this long term research project.

900 m of the 2 km reach of the Kaawalii Stream within the EF were surveyed during the last week of September, 2007. Cross-sections were installed at randomly pre-selected locations on successive 100 m segments of the stream. The cross-sections were permanently monumented, photo-documented, located with GPS coordinates, channel-typed using the Rosgen method, and measured for substrate composition using the pebble-count method. The Kaawalii Stream in the Hawaiian Wet Forest vegetation zone of the LEF is one of five streams on LEF and is the number one priority for future research efforts. No channel surveys have been done to date because of the recent nature of the EF establishment.
