| Habitat variable | Description |
| Microhabitat | |
| Soil temperature | Soil temperature using a digital thermometer (˚C) |
| Soil moisture | Soil moisture using a meter that quantifies moisture on a continuous scale from 1 (very dry) to 10 (very wet) |
| Canopy cover | Percent canopy above the midpoint of the microhabitat plot using a spherical densitometer |
| Small trees | Percent of plot covered by trees less than 5 m in height |
| Medium trees | Percent of plot covered by trees 5 to 10 m in height |
| Tall trees | Percent of plot covered by trees more than 10 m in height |
| Ground cover | Average % cover each of trees, shrubs, grass, moss, herbs, and vines, logs, stumps, and other woody debris |
| Evenness of living ground cover | Smith and Wilson evennessa of the classes of living ground cover |
| Evenness of non-living ground cover | Smith and Wilson evennessa of the classes of non-living ground cover |
| Macrohabitat | |
| Small tree density | Density (per m2) of trees less than 5 m in height |
