Understanding the ecological processes that govern forest development over time and predicting future stand growth and yield from these processes are one of the primary challenges in forest management planning. Tree growth is controlled by solar radiation, water availability, nutrient availability and site variables such as temperature and precipitation. Decision making and planning in forests of variable land and forest conditions, such as those in Nova Scotia, require methods of estimating forest site productivity for each of the important tree species. Therefore, the objective of this paper is to determine the degree to which the five main environmental variables (i.e., solar radiation, soil fertility, soil drainage, temperature, and precipitation) explain variation in tree and stand growth in Nova Scotia. Potential forest productivity maps will be created for each of the main environmental variables, showing potential productivity classes from “very low” to “high”. Significant differences in the growth rate relationships will be used to refine the individual environmental variable maps. A site quality map based on the five potential productivity maps may provide a useful means for estimating site potential as a basis for silvicultural and sustainable forest management decisions.
