Corey, Donald J.2023-06-072023-06-071972https://unbscholar.lib.unb.ca/handle/1882/33378This thesis discusses the present reforestation program being carried out in the Black Brook district. of northwestern New Brunswick by J.D. Irving Limited. Planting of cut-over areas was initiated in 1951 and presently more than 25 million trees have been planted on about 25 thousand acres; black, red, and white spruce were the major species planted. Estimated costs of plantation establishment include $60 / acre for planting $17/acre- for site preparation and $7/acre for herbicide application. Average survival rat.es of 87%, five years following planting have been obtained, as well as an average growth in height of 14 inches during the seventh growing season following planting. Company predictions call for a yield of 6.0 cords per acre at the end of a short 35 year rotation. However, yields of from 30-40 cords per acre would appear to be more reasonable under present harvesting methods.iii, 55 pageselectronicen-CAhttp://purl.org/coar/access_right/c_16ecsenior reportEarth Sciences
