Growth of young saligna eucalyptus in Hawaii: 6 years after thinning

Abstract

The effect of thinning on growth rate and quality of a 6-year-old Eucalyptus saligna Sm. stand on Maui, Hawaii, was studied by testing three levels of thinning from below: 100, 85, and 70 sq ft per acre (23, 19.5, and 16 sq m/ha). The stand had an average basal area of 102 sq ft per acre (23 sq m/ha). Initial spacing was about 10 by 10 feet. During the next 6 years, no significant differences in growth response were found among the three treatments. Basal area increased to an average of 144 sq ft per acre (33 sq m/ha) at age 12, and the average height of dominant and codominant trees increased from 71 to 100 ft (22 to 30 m). More time must elapse before effects of thinning on the quality of the residual trees can be determined.
