Yukon Bioclimate Zones and Subzones Derived from 30m DEM

Yukon Bioclimate Zones and Subzones Version 1.0 is a spatial classification derived from a 30-meter Digital Elevation Model and rule-polygons defined by field data, expert observation, and imagery. The mapping is designed for use at scales larger than 1:250,000 and is part of an ongoing project subject to periodic updates.

Use Cases

• Intersect rule-polygons with a terrestrial landcover layer using the defined upper and lower elevation limit attributes.
• Analyze the spatial distribution of bioclimate zones and subzones derived from the 30m DEM for ecological modeling.
• Validate rule-polygon attributes, such as elevation limits, against field data from representative reference sites.

Strengths

• Derived from a high-resolution 30-meter Digital Elevation Model (DEM).
• Rule-polygon attributes are defined by field data, expert observation, and available imagery.
• Mapping is deliberately extended across non-terrain features to facilitate intersection with other landcover layers.

Limitations

• Recommended for use at scales larger than 1:250,000 only, limiting high-detail applications.
• An ongoing project subject to updates, requiring users to verify they have the most current version.
• The custodian acknowledges there may still be errors in the spatial products despite quality efforts.
