This paper describes the decadent condition of the 10,500 acres of the Honaunau Forest, situated on the west side of the Island of Hawaii. This forest lies at elevations of 2,300 feet (average rainfall 105 inches per year--temperature 70° F.) to 4,800 feet (average rainfall 48 inches per year--temperature 64° F.). Soils are volcanic, for the most part shallow. During the past seven years, 850 acres have been cleared and planted at an average cost of $38.72 per acre. The bulk of the area has been planted to Hawaiian ash (Fraxinus uhdei) and Toon, Australian redcedar (Toona ciliata var. australis). Various eucalyptus species, Nepal alder, loblolly and slash pine, Queensland-maple, etc., have been planted in small blocks. The summary of growth shows ash at three years to be one to 29 feet, high; Toon (Australian redcedar) up to 42 feet high. The cutting cycle is judged to be 30 to 40 years with volumes of 30,000 to 50,000 bd. ft. per acre. Predicted returns, over the 7 percent capitalization, should be about $900 per acre net. Problems such as type of stand, clearing by machine or chemicals, thinning call for long research. More pressing problems concern tree selection for better growth, a cure for ash lodging and brooming, detailed soil analysis, mycorrhizal effects, disease and insect control.
