Biogeoclimatic Maps (zone or subzone/variant)

Scale of Mapping

This map is a work in progress. The original subzone/variant boundaries were drawn by hand on maps ranging in scale from 1:100,000 to 1:600,000. Since 1999, regional ecologists have been working to systematically revise the original "legacy" lines. The current scale of mapping varies from 1:20,000 to 1:600,000. Refer to the Scale of Mapping PDF for the spatial distribution of the various mapping scales.

Note that with any major update there will be border matching issues. These occur primarily where newer large-scale mapping has been completed adjacent to "legacy" small-scale mapping, and where newer large-scale mapping has been completed adjacent to existing, but significantly older large-scale mapping.
