A few years ago I remember running across a document/database that listed many North American trees and shrubs and their various characteristics including things like habitat, distribution, seasonal wildlife forage value, etc. Most importantly for what I’m ruminating about it included a ‘fire rating’. The fire rating, if that is the right term, was an assessment of how flammable or fire resistant a species was.
Is anyone familiar with this? For the life of me my aging brain can’t remember what this document was called. Any ideas?
