Anywhere the land was tended with fire and subsequently fire suppressed (including the coast and islands) one could try again to beat back the Doug fir. But we don't have the same historic objectives (we're worried about wildfire rather than food supply and ease of travel). Each needs its own work.
The project map is good for seeing where work is, but the WA map doesn't make it easy to see how big these projects are or what kind 😐 A roadside project on San Juan Island at $625 an acre counts, but looks different than central or eastside timber. foresthealthtracker.dnr.wa.gov/Results/Proj...
I agree, Tribes used (and are bringing back) traditional fire in lowland prairies and to maintain berry patches in some higher elevation areas, but my understanding is west-side forests produce fuels too quickly to be maintained this way at scale. The fire regime is just so different from the east.
