From: Short-Term Impacts of Fire-Mediated Habitat Alterations on an Isolated Bighorn Sheep Population
Covariates | Description |
|---|---|
aspect | Dominant cardinal direction within each sampling unit. North used as reference factor. |
dist_burn | Sampling unit center to nearest (m) burned habitat edge calculated after fire events. |
dist_escp | Sampling unit center to nearest (m) escape terrain (slope > 27°)*. |
dist_road | Sampling unit center to nearest (m) road. |
dist_water | Sampling unit center to nearest (m) perennial water source. |
elev | Average elevation (m) within sampling unit. |
slope | Average slope (°) within sampling unit. |
pre.post | Binary variable (1 = after fire treatment; 0 = prior to fire treatment). |
Int | Interaction term (pre.post × dist_burn). |
