Abstract

This report details a study designed to provide data as to the annual cycle of basal area growth of the principal conifers in Ireland. The study was initiated in the Spring of 1961. The species chosen for investigation were Sitka and Norway spruce and Pinus contorta. The prime object of the investigation was to obtain a graph of the accumulating percentage growth over the growing season for these species. It was hoped to obtain some information as to whether such factors as region, species, age, quality class, or the position of the tree crown in the canopy, were of practical significance in the volume increment cycle...
