Forestry & SocietyForests of New Mexico & SW/Questions
• Compare the forests of NM, AZ, and CO.• Discuss the impacts of elevation, aspect (N,S,E,W)
and latitude on species composition.• Place in order of occurrence as you climb up the
mountain, and give approximate elevation: aspen, Douglas-fir, juniper, oak, piñon, ponderosa pine, spruce, white fir, and mesquite.
• What types of forest products are harvested in NM? Who owns the land?
• Describe the piñon-juniper woodland; location, diversity, species, climate, soils.
