Coppice Sycamore Yields Through 9 Years

Abstract

Cutting cycle and spacing did not significantly affect sycamore dry-weight yields from ages 5-9 years (1974-l 978). Longer cutting cycles usually did give higher yields. Dry-weight yields ranged from 2886 lb per acre (3233 kg/ha) per year in the 1 year, 4x5 ft (1.2 x 1.5 m) spacing to 4541 lb (5088 kg/ha) in the 4-year, 4x5 ft s,pacing. Survival averaged 67 percent in the 2x5 ft (0.6x1.5 m) spacings and 79 percent in the 4x5 ft spacings. Ratio of dry weight to fresh weight averaged 49 percent, and the stem accounted for 85 percent of the dry weight of the trees.
