Sonoran DesertAccess and Closure Maps

The Pima County ranch properties and other open space lands are intermixed with or surrounded by Arizona State Trust lands, federal public lands and/or private lands. The lands are managed by the respective owners and Pima County respects their rules and regulations. In most cases, Pima County only has grazing leases over the non-county state or federal lands within an identified ranch boundary.

The rules and regulations of the actual agency land owner always take precedent on their lands. As a visitor to any of the properties, it is YOUR responsibility to know the land status at any point within the ranch boundary and the applicable rules and regulations for those lands near or within a Pima County ranch boundary. Access to Pima County lands on roads across another agency's lands within a ranch is not always guaranteed to the public. Always follow posted regulations and road closure notices.

grasslandThe Use Activities identified in the table below are ONLY for the lands owned by Pima County within a ranch or open space property.

mountainsManagement Plans

Over the past several years, the Natural Resources, Parks and Recreation (NRPR) management team has been working on a variety of strategies to enhance ongoing conservation management efforts on the growing land base identified under the Sonoran Desert Conservation Plan.

In an effort to establish a set of Standards and Guidelines for NRPRs grazing program, the county has consulted with many individuals, other land management agencies and University range program staff. The result of that effort has been the development of the documents linked below.
mule deerHunting in all Pima County parks is closed unless specifically opened in the Arizona Game and Fish regulations. Tucson Mountain Park has archery hunting, with a special Game and Fish permit required, but portions of the park are closed and it is the responsibility of the hunter to know the new closure areas. Hunters must never drive on private roads or cross private property to access the open portions of the open parks unless they have permission from landowner. Hunters must stay more than ¼ mile distance from any developed park area or adjacent residence. Within Tucson Mountain Park along Kinney Road and Gates Pass Road there is a posted no shoulder road system, so there is no parking along the roadway outside of the paved turnouts or paved overlooks. Maps for Tucson Mountain Park are posted in the park and are on this website. Hunting in other Pima County Parks in the Tucson Mountains such as Sweetwater Preserve, Feliz Paseos and Robles Pass is closed at all times as well as the discharge of firearms and archery equipment.

Were your hummingbird feeders mysteriously drained during the night this past summer? Did you know the midnight raiders were bats? Most of Arizona’s 28 bat species eat insects, but two species drink nectar and eat pollen and fruits from plants such as the saguaro, agave and your hummingbird feeders. The Arizona Game and Fish Department and the U.S. Fish and Wildlife Service with cooperation from the Town of Marana will be commencing our 2015 Nighttime Hummingbird feeder bat monitoring project and we need your help!
