Arizona Natural Infrastructure Composite (May 2008)

GIS data set that integrates 10 local, state, and regional datasets which identify open space lands and sensitive biological lands. This data set is a composite or simplification of the source data sets – the boundaries of all individual data layers have been dissolved into one composite data layer. Note: We did not integrate wildlife linkages data from 2 of the studies in this composite layer because we are awaiting to obtain permission from the source agencies.
