Spruce-fir: A different kind of forest

Toby Gass, USFS, retired, will discuss the forests of Engelmann spruce and sub-alpine fir that cover the higher elevations of the Sangre de Cristos. The ecology of these forests differs greatly from that of the ponderosa. Come learn how and why these two types of forests differ so much and learn to distinguish a spruce, a fir, and a Douglas-fir at the same time!
