            May 7, 2022 - Discovering the Land

The Cienega Watershed Partnership and Friends of Sonoita Creek are co-hosting the Science on the Sonoita Plain Symposium, but with a new twist. This year, we are taking it outdoors to Empire Ranch in Sonoita and The Nature Conservancy's Patagonia-Sonoita Creek Preserve in Patagonia.  We want to provide a wide network of regional partners the opportunity to highlight community science initiatives in the watershed. You are invited to share your experience with local and regional partners, stakeholders, and community members in a day of exploration. Sign up - here - https://www.eventbrite.com/e/294918247417 to attend and get more details soon about speakers, guests, and events.

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
