Did a Brief ALB Survey at this Nature Preserve. I observed bug damaged to downed trees immediately At the turnaround point in the mapping trail I observed a bug damaged live tree, over 60 feet tall, deciduous hardwood. I took multiple sample of bug parts and casings for analyzing later. The photos I took of the damage and the whole tree did not save. I planned to ID the tree from the photos. I will return to this preserve in the near future as there does appear to be evidence of unidentified beetles.
