Spatial domainPima County
AbstractDisplays ironwood tree special element locations. Original coverage provided by PAG. Ironwood tree polygons selected out of this coverage. See more information.
Known errors/qualificationsNot reliable in riparian areas since these have changed significantly since the 1970's.

Boundaries have been further refined around the Tortolita Fan based on vehicular and aerial ground-truthing field surveys conducted by Julia Fonseca. Boundaries in this area generally, but not always, follow Arizona Geological Survey geomorphic units.
