- the Nature Conservancy
- the Wilderness Society (TWS)
- the Natural Resources Defense Council (NRCD)
- the Sonoran Institute
Originally TWS and the NRDC joined with SunZia and the BLM to work on routing SunZia in a collaborative effort with the environmental community. The Sonoran Institute, a public-interest organization in Arizona, subsequently partnered with them. We now have strong differences of opinion on SunZia with the Sonoran Institute.
- Redington Natural Resource Conservation District
- Winkelman Natural Resource Conservation District
We continue to work closely with these ranching organizations on SunZia, as they share many of the same rural concerns in the San Pedro Valley that we do.
- Tucson Audubon Society
- Sierra Club, Grand Canyon Chapter
These are the two more traditional environmental organizations with which we have worked. Collaborative efforts include writing articles on SunZia and letters of mutual concern.
- We have had some contact about SunZia with:
- Vail Area: Elizabeth Webb of the Empire-Fagan Organization
- Avra Valley: Albert Lannon of Wild Heart Ranch (in Picture Rocks area)
- Aravaipa Region:
- Klondyke Community (East side of the Galiuro Mountains)
- Mammoth Community - Friends of the Aravaipa Region (West side of the Galiuro Mountains)
- J-6 Ranch Community (Along I-10 between Benson and Tucson)
- In efforts to steer SunZia in a better course, we have had discussions with:
- the Pima County Administrators office
- Supervisor Richard Searle of the Cochise County Board of Supervisors
- the Arizona Game and Fish Department
- Congressman Giffords’ and Grijalva’s offices
- We have attempted to create the broadest range of relationships that we can in assessing and finding a solution for SunZia while protecting areas of high environmental concern.
