Where I live (Sierra foothills), the Oaks are enjoying the space opened up by the Pine tree die-off thanks to bark beetle. People are paying thousands of dollars to cut down towering pines.
I have five enormous oaks and four full-size pines on my 1 acre lot. That adds up to a potential liability of $18,000 or more. Doing nothing does not sound appealing.
Maybe we should do nothing, and let trees that are more capable of surviving fill in the gaps left by the oaks.
