Table 1. Description of variables (and keywords) used in the habitat models. All variables calculated using hexagonal analysis units generated in LSL.


Variable Scale Acronym Description
Tree height Local HEIGHT Weighted average of Ontario forest resource inventory (FRI) height, as measured from aerial photography using a parallax bar.
Percent hardwood volume Local HARDWOOD A measure of cover type. Percentage of total merchantable timber that is hardwood. Interpolated from yield curves for standard forest units. Low levels indicate softwood cover type, high levels hardwood cover type.
Percent canopy closure Local CANOPY Interpolated from FRI stand age.
Average Stand Age Local AGE Weighted average of FRI stand age. Interpretation based on stand height and texture.
Percent Young Forest Local YOUNG A measure of young forest cover amount. Percentage of total forest <20 years.
Contrast Weighted Edge Density Landscape EDGE A measure of forest cover configuration. Contrast weighted density of edge between young (<20 years old), immature, and mature (>60) forest, where young/mature forest has a contrast weight of 1, and immature a weight of 0.5.
Percent Mature and Old Forest Landscape INTACT A measure of intact mature forest cover amount. Percentage of total forest >80 years old.
