Aim We developed an ecosystem classification within a 110,000-ha Arizona Pinus
ponderosa P. & C. Lawson (ponderosa pine) landscape to support ecological
restoration of these forests. Specific objectives included identifying key
environmental variables constraining ecosystem distribution and comparing
plant species composition, richness and tree growth among ecosystems.
