It’s hard going back into the office after spending a gorgeous Sunday wildlife tracking in the southeastern Arizona desert grasslands of the Appelton-Whittel Audubon Research Ranch. The Sky Island Alliance uses volunteers to ground-truth wilderness proposals, delineate roadless areas, and track large mammals that travel across these desert grasslands between the sky island mountain ranges. Yesterday, we had more than 20 volunteers, mostly new, to help monitor four track transects across this awesome landscape. As the field and volunteer coordinator and a conservation biologist for the Sky Island Alliance, I feel good knowing that we are not only investigating corridor use by animals, but also building strong and lasting advocacy groups in the protection of the landscapes of southern Arizona.

We didn’t find a lot of tracks or signs, but what we did find is encouraging: a small Sonoran mud turtle (Kinosternon sonoriense) and two black-necked garter snakes (Thamnophis crytopsis), both riparian obligate species. Our finds show the resilience of these desert grasslands where, after 100 years, grazing was halted and all cattle removed in 1968. We also found what we think is black bear (Ursus americanus) scat. Bears have been verified crossing the research ranch before, most likely between the Huachuca and Santa Rita Mountains.

Back in the office, the first thing I have to do is send thank-you notes to our volunteers and the hosts at the research ranch. Then it’s time to break out the topo maps of our next field weekend and figure out what roads we will have our volunteers walk and what information we need to collect. The next weekend is in the Gila Mountains of southeast-central Arizona. The Gila Mountains contain the Fishhook Wilderness and a BLM Wilderness Study Area. We will collect data on characteristics and conditions of the roads that enter these two areas and record all animal and plant species that make this area unique.

With this information, we will build a case for road-closures and expanded wilderness in this rugged, remote, and rarely visited area that even BLM land managers have very limited information on. We also hope to make contact with the people who do actually know a bit about this area: the ranchers who run their cattle on the BLM grazing allotments that surround the existing and proposed wilderness. These are the people who know what’s out there and who can help to protect the wilderness values of the area by fencing the few riparian areas, by moving their cattle more frequently, or by perhaps lowering their stocking rates. We are dedicated to keeping lands surrounding wilderness areas as wild lands that can support local stewards, economies, and connectivity between wilderness and other preserved lands administered by the BLM and Forest Service.
