Topics included new exotic species, mosquitoes, pollinators, carpenter ants, etc.
This is a nicely written and very informative article on the importance of collecting.
Mitch Michaud (USDA NRCS, Kenai), phoned me regarding substantial defoliation of spruce at Halibut Cove and the Homer bench. At Halibut Cove, spruces had been dropping many needles.
Aphids were the culprit, but the identity of the aphids has not yet been established.
In the last two weeks there have been numerous reports of aspen defoliation in the Goldstream Valley on the north side of Fairbanks. An area approximately 50 acres in size has been heavily defoliated by the caterpillar, large aspen tortrix (Choristoneura conflictana (Walker)). Brief, intense outbreaks are common throughout the range of aspen, and typically last 2-3 years before collapsing. These outbreaks can grow to cover thousands of acres. The larvae tie together leaves with webbing and feed on the plant tissue. They will web other species of plants and feed on them if they run out of available aspen foliage. Although the forest can look very grim, leafless and covered in webbing, the trees will often create a second flush of leaves later in the summer. Historically there has been little long-term damage to the aspen trees associated with past outbreaks.
