The book provides information essential for anyone interested in the
ecology of the American Southwest, including land managers,
environmental planners, conservationists, ecologists and students. It is
unique in its coverage of the hows and whys of dynamics (changes) in the
major types of vegetation occurring on southwestern mountains and
plateaus. It explains the drivers and processes of change, describes
historical changes and provides conceptual models that diagrammatically
illustrate past, present, and potential future changes. All major types
of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine
forests, pinyon-juniper vegetation, subalpine-montane grassland, and
Gambel oak and interior chaparral shrublands. The focus is on vegetation
that is relatively undisturbed, i.e., in natural and near-natural
condition, and how it responds to natural disturbances such as fire and
drought, as well as to anthropogenic disturbances such as fire exclusion
and invasive species
