Southern Galiuro Erosion Control Structures: November 19 – 21

November 19 @ 2:30 pm - November 21 @ 6:00 pm

Join Sky Island Alliance on a weekend volunteer trip as we install rock structures on a formerly overgrazed property in the Galiuro Mountains.


Sky Island Alliance has partnered with the U.S. Fish and Wildlife Service to install erosion control structures near the Muleshoe Ranch in the southern Galiuro Mountains. A few years ago, we installed ponds for wildlife on this land — and now we are returning to improve the site further. We will be creating loose rock structures to halt erosion, increase water absorption, and support plant growth in drainages throughout the property. These low-tech structures can make huge differences and are a great tool for transforming landscapes.



We will be building rock structures which will entail carrying, moving, and placing rocks of various sizes. Some heavy lifting will be required, though no one will be asked to lift more than they feel capable of. Be prepared for getting dirty as we will also be digging as a part of the building process.

We will also be camping over the weekend. The landowners of this beautiful property are providing us with plenty of great spots to set up tents, but will have access to a bathroom and potable water onsite. Bring your own camping gear (or contact us if you need to borrow some) and meals for the weekend: a minimum of 2 breakfasts, 2 lunches, and 2 dinners, with snacks.

Also, be prepared to unplug as cellphone service is spotty or non-existent at this location.



To keep our volunteers and staff safe, we’re taking these precautions:

  • Limiting the group size to 10 volunteers. If you’d like to bring kids, please contact us first.
  • Driving separately. You can either meet us there, or caravan with us from SIA’s office.
  • Camping, and having each household bring their own food, camping gear, and cooking gear.
  • You’ll get your own tool(s) to use for the duration of the weekend, and we’ll stay safely spaced out while working.
  • Keep a mask handy in your pocket at all times.
  • Working outside, of course!
  • Wearing masks inside the bathroom and wiping down surfaces with sanitizer after each use.
  • Bring your own work gloves if you have them.
  • We’ll have a thermometer available in case anyone starts feeling off.



  • Friday: Meet at 2:30 pm at our office: 3127 N Cherry Ave, Tucson, AZ 85719 at the SW corner of Cherry Ave and Fort Lowell Rd. To carpool or caravan to the site (Covid permitting). There is parking in our lot off Cherry.
  • Friday/Saturday: If you’d prefer to meet us at the worksite, Please join us after 5:00 pm Friday or by 8:30 am Saturday (directions will be sent to registered participants) keep a lookout for our green SIA signs pointing the way.
  • Saturday: We will start work around 8:30 am, work throughout the day with a break for lunch, and end by 5 pm.
  • Sunday: We will start work around 8:30 am, work throughout the day with a break for lunch, and be back to the office by 6:00 pm (or earlier).



  • Water, snacks, and food for 2 breakfasts, 2 lunches, and 2 dinners
  • Binoculars – this is a fabulous birding spot!
  • Sturdy footwear (e.g., hiking boots) that you don’t mind getting dirty or muddy
  • Sun protection (e.g., wide-brimmed hat, sunblock, long sleeved shirt, long pants)
  • Sturdy pants: we will be kneeling and working in the dirt, sand, and rocks, so you’ll want pants that are up to the task
  • Sky Island Alliance will provide all tools and work gloves, though if you have a pair of gloves you like, feel free to bring them.

Unfortunately, pets are not allowed on this trip.
