Book Description
Excerpt from Damage by the Sitka Spruce Weevil (Pissodes Strobi) And Growth Patterns for 10 Spruce Species and Hybrids Over 26 Years in the Pacific Northwest The relation between degree of weevil infestation and plantation age (fig. 2) was developed using smoothing procedures described by Tukey Data smoothing is an exploratory statistical procedure that summarizes data by describing the central trend and reducing variation. No assumptions are made about model form, and no mathematical prediction model is developed. This approach was selected because the temporal length of the data set was too short to be sure of a model form.

Ecology and Management of Sitka Spruce
Author: N. Merle Peterson
Publisher: UBC Press
ISBN: 0774844256
Category : Technology & Engineering
Languages : en
Pages : 360
Book Description
Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
