Pine Tree Infestations

Patterns of dried pine needles on the trees near Lake Roosevelt

We’ve been seeing many pine trees with partially browned needles.  We didn’t think that pine trees changed colors for fall, and they drying didn’t appear to be due to drought.  Later, a park ranger at Glacier National Park told us that the trees were suffering from pine moth infestation.  It’s disheartening to see vast amounts of damage to our forests from pine moths and spruce beetles.  We so often take our trees for granted.
