Spruce, fir sale designed to combat budworm infestation

Budworm spreading beneath forest’s canopy
The destructive force of the roundheaded pine beetle is shown in the Lake Canyon area.
The lack of needles on the recent growth on these branches shows the effects of spruce budworms. The new growth on the branches should be full of new needles, but some of these branch tips have none. Note that some tips do have new needles, so not all new growth was hit.
Forest visitors often encounter the Western spruce budworm as it descends from trees on a thread of silk.
The budworm transforms into a moth.
A budworm infestation in the Taylor and Stoner Mesas north of Dolores is defoliating trees.
Jed Botsford, a Columbine Ranger District Recreation officer, skis along a mix of trees damaged by the spruce budworm.
