Physical and biological events such as wind, fire, insects, disease, and invasive species can affect how well regenerating tree species establish.
To evaluate the ecological suitability of a tree species in light of these potential events, consider factors like regional forest health hazards and risks, and tree species resistance and tolerance to frost and drought.

Stand-level Frost and Drought Risk
A MS-Excel application has been created that generates the frost hazard for an area based on its BEC unit, slope gradient, and slope position. The tool provides an assessment of the suitability of tree species based on the frost hazard for an area and a description of additional factors that may decrease or increase the indicated frost hazard. The application currently has data for a portion of the Cariboo region.

A MS-Excel application that allows users to calculate the relative risk of drought induced mortality for a species based on BEC unit and Relative Soil Moisture Regime. The tool provides an estimate of the drought risk for the current climate, as well as predicted climates for 2020, 2050, and 2080. The tool currently contains data for the Prince George TSA and Cranbrook TSA.
