Additional Information

Lineage Statement

Slope/aspect categories are pulled from the Slope/Aspect Categories in Mule Deer Winter Range - Cariboo Region dataset.

[Stand_Struct_Hab_Type_Limit] is the stand structure habitat type limitation within Interior Douglas Fir (IDF) and Bunch Grass (BG) BEC zones within mule deer winter range in the Cariboo Region. Values are derived from the slope and aspect categories in combination with the BEC zone. Possible values are high, moderate, or low. This field is only populated for polygons that fall within IDF or BG BEC zones.

[Slope_Category] is based on the slope percentage from 25m raster slope tiles.

  • Flat: 0-10% slope
  • Moderate: 11-30% slope
  • Steep: 31-60% slope
  • Very Steep: >60% slope

[Aspect_Category] is based on aspect degree from 25m raster aspect tiles.

  • Cool: 316-60 degrees
  • Moderate: 271-315 degrees or 61-135 degrees
  • Warm: 136-270 degrees

[Slope_Aspect_Category] is derived from the [Slope_Category] and [Aspect_Category] fields. Values range from 1-10.

  • 1: Slope_Category = Flat & Aspect_Category = any value;
  • 2: Slope_Category = Moderate & Aspect_Category = Cool;
  • 3: Slope_Category = Steep & Aspect_Category = Cool;
  • 4: Slope_Category = Very Steep & Aspect_Category = Cool;
  • 5: Slope_Category = Moderate & Aspect_Category = Moderate;
  • 6: Slope_Category = Steep & Aspect_Category = Moderate;
  • 7: Slope_Category = Very Steep & Aspect_Category = Moderate;
  • 8: Slope_Category = Moderate & Aspect_Category = Warm;
  • 9: Slope_Category = Steep & Aspect_Category = Warm;
  • 10: Slope_Category = Very Steep & Aspect_Category = Warm;
