bgxh1 forested sites on N slopes

forested areas tend to be restricted to N facing slopes -but ponderosa pine (Py) is not shade tolerant spp so not likely to increase in suitability on these sites despite projections that it will do better than douglas fir. Douglas fir is more shade tolerant naturally.

No files or tests are identified. Review the BGXH1 note about forested north-facing slopes, ponderosa pine shade tolerance, and Douglas fir projections; determine whether the suitability projection is inconsistent with those assumptions and document the evidence and conclusion in the issue.
