Letter Writing Campaign

Thanks for participating in the Letter Writing Campaign to remove cattle from the Important Birding Area at Patagonia Lake..  We are happy to report that that two grazing leases have been revoked and the State has no plans to renew the leases in the future. Read about it in the Patagonia Regional Times.

Read more about restoration issues for this critical reach of Sonoita Creek in our September newsletter.

Research, Restore, Educate & Collaborate

Founded in 2004, Friends of Sonoita Creek (FOSC) works to protect and restore the water and natural habitat of Sonoita Creek and its watershed. We inform residents and visitors about the importance of Sonoita Creek to life forms and its relationship to the geography through hands-on activities, presentations, hikes, and financial support to kindred organizations.

Sonoita Creek flows a distance of 30 miles, above and below ground, southwest from Sonoita into the Santa Cruz River north of Nogales. The watershed drains 258 square miles, has unique geological features, seven biomes with a great diversity of plant and animal species, and vast natural beauty.

It is a cultural crossroads with protected ancient archaeology sites, a Spanish colonial past, and mining, ranching and railroad history.

Join in and help us in our cause and educational activities:

  • Hosting guided nature bird and plant walks
  • Supporting programs protecting our watershed
  • Teaching our Healthy Water Education Program to students
