Pine needles

Asked August 7, 2018, 10:14 AM EDT

Good Morning, I live in Dillingham, AK and have noticed an obvious change in a significant number of pine trees in the area. The pine needles have turned an orangish/reddish color and they even produce a “dust” or “pollen” (for lack of a better term) that can be seen in puddles, lakes, and ponds. A number of residents are wondering about the cause, including myself. I’m wondering if there is anyone at the cooperative extension that might be able to provide an explanation. Sincerely, Jon Clouse

This is almost certainly the result of Spruce Bark Beetles. Here is a link to a University of Alaska Fairbanks Cooperative Extension Service publication that you may find helpful: https://www.uaf.edu/files/ces/publications-db/catalog/anr/PMC-10067.pdf
