Description

The results of the surveys reported here provide a summary of the biotic and abiotic agents affecting cones, seedlings and trees, gives a distributional summary of damage agents according to plantation sites established within the province up to 1994, and indicates the relative importance of each agent. The report also provides a listing of unpublished technical reports that resulted from the work described here and can be referred to for further details where necessary.

Description

This paper describes the pattern of genetic variation for growth potential among white spruce provenances in Alberta. It uses total height and diameter at breast height at 27-years from seed to identify provenance differences in relation to latitude and elevation of weed origin. Latitude and elevation are the main variables that adequately describe climatic variability in Alberta.
