Survival and growth of interior spruce plantations in the Cariboo Region of British Columbia
University of New Brunswick
During the summers of 1979 and 1980, survival and growth data were collected from 203 spruce plantations established by the British Columbia Ministry of Forests in the Cariboo Forest Region. The plantations of 1-0, 2-0, and 2-1 stock evaluated were located on a wide range of site types. Comparisons were made on the basis of stock type, biogeoclimatic subzone, method of site preparation, and time of planting. It appeared that, for the region in general, the mean heights of surviving plantations equalled or exceeded the chosen standard of acceptability. Taller seedlings showed initial superiority in total height after planting, but the difference became less evident in time. It was recommended that survival estimates and performance evaluations be dealt with as separate, but complementary operations.
