Title: A spacing trial in Australian Toon ... an interim report

Station ID: RN-PSW-220

Description: Australian toon (Toona australis) was planted at four spacing intervals-6, 8, 10, and 12 feet-in a trial on the island of Hawaii. Measurement of 8-year-old trees showed that spacing interval did not affect diameter or height growth or survival; but basal area per acre decreased as spacing increased. A goal of 400 acceptable and desirable pole-sized trees per acre can be reached by using good planting technique and an initial spacing of slightly less than 9 by 9 feet, and by weeding the first year.

Keywords: Toona australis, species trials, planting density, Hawaii
