The chart at the right shows the basic land components of National Forests in Arizona and New Mexico.

Nearly three quarters is covered by forests.    Half the forested area is woodland, primarily composed of trees like oak, piņon and juniper.  The other half, referred to as timberland, is composed of trees like ponderosa pine, Douglas-fir, spruce and aspen.

One-third of the timberland is reserved.  This means timber harvest activities are prohibited.  Most of the reserved area is in designated wilderness areas.

The non-reserved timberland is managed for a wide range of resource objectives.  Vegetation treatments, including timber harvest, are generally allowed where they fit in with objectives set for a particular area.  Much of the non-reserved timberland has primary objectives of providing habitat for goshawk or Mexican spotted owl.
