DULUTH, Minn. (AP) - The Minnesota Department of Natural Resources say a recent surge in the population of budworm is threatening balsam fir trees in the Cloquet Valley State Forest.

The spruce budworm is native to northeastern Minnesota. But, DNR forest health specialist Mike Albers says there are more than 15,000 worms in the area this year compared to a couple hundred worms last year.

WDIO-TV (https://bit.ly/1naCPPW ) reports the DNR is doing an aerial survey to find out how many trees have been defoliated by the worms. Albers says the outbreak happens every 30 years or so and the forest will recover as it has in the past. The DNR advises private land owners to remove dead trees to decrease the fire hazard.
