Aerial surveys conducted this summer by state and federal forest health specialists documented nearly 558,000 acres of active spruce beetle-caused tree mortality in Southcentral Alaska. The surveys are part of an annual program to detect forest insect and disease occurrences in Alaska forests. With the addition of this year’s data, the cumulative area impacted by spruce beetle in the region is estimated to have grown to roughly 910,000 acres since the current spruce beetle outbreak began in 2016.

The University of Alaska Museum Insect Collection is a biorepository for vouchers from varied projects throughout the state. A number of examples of possible and potential climate change impacts on the terrestrial invertebrates of Alaska will be presented. These will cover various taxa including snow-field associated rove beetles, butterflies, ants, and earthworms. This work will be put in a global context.
