Many of the trees killed by #AlaskaSpruceBeetle have red belt, a decay fungus that weakens stem strength. Spring wind events in Anchorage have caused many dead spruce to snap, be sure to avoid these areas when it’s windy! #AlaskaForestHealth https://www.fs.usda.gov/detailfull/r10/forest-grasslandhealth/?cid=FSEPRD538180&width=full

Bear scratch fever! Bears mark, scratch & even feed on the inner bark of trees in spring. Wounds create entry points for stem decays, which can eventually develop into decay hollows for future den habitat! You scratch my tree, I’ll scratch yours. #BearAware #AlaskaForestHealth
