Fig. 5.3a. Red pines attacked by bark beetles at Itasca State Park. Photos are of the same tree (#713 in Table 5.1) taken in September 1998 (left) and September 1999 (right). Tree was reduced to about 10% of its live crown by 1999, and will probably be dead by September 2000. See Fig. 5.3b for a tree that may survive infestation by Ips.
