Book Description
After many decades of land development & forest exploitation across southern Ontario, only remnant stands and scattered groups of white spruce remain. A primary concern is to avoid such widespread loss or depreciation of the white spruce gene pool. A gene pool conservation program was initiated in 1980 to identify the remaining white spruce in southern Ontario. To accomplish this, a survey was undertaken to locate & catalogue the residual white spruce. This report describes the survey methodology and presents some results regarding the number of white spruce stands by district and the estimated number of trees per stand. Finally, recommendations are made for subsequent activities in white spruce gene pool conservation.

Book Description
Geographic Variation in Forest Trees is the first book to examine this subject from a world-wide perspective. The author discusses population genetic theory and genetic systems of native North American tree species as they interact with environments in the major climatic regions in the world. He then demonstrates how this knowledge is used to guide seed zoning and seed transfer in silviculture, basing much of his discussion on models developed in Scandinavia and North America. In the final chapter, the author addresses the issue of genetic conservation -- a subject of great concern in the face of accelerated forest destruction, industrial pollution, and climatic change. This comprehensive, well-researched book makes a significant contribution to the knowledge of one of our most important renewable natural resources.
