During Pandemic, Community Scientists Adapt to Save the Desert
Tucson, AZ – The Coalition for Sonoran Desert Protection is celebrating their Volunteer Appreciation Week on September 7-12, 2020, this year virtually. The nonprofit organization made swift changes to accommodate remote work, shutdowns, and social distancing in the last six months since the pandemic hit, in an effort to reduce negative impacts on volunteers and support their ability to do science. Despite current challenges, the Coalition’s community scientist volunteers have kept up their enthusiasm to protect the Sonoran Desert.
“It wasn’t long ago that we had volunteers shoulder to shoulder together with 400 students for Critter Cam Field Day in Catalina State Park last March. Things have changed a lot since then,” says Jessica Moreno, the Coalition’s Conservation Science Director. “But I’m amazed at the participation and community spirit volunteers have shown during this time.”
The Coalition is an alliance of 30 member groups representing over 30,000 members, and has a small staff of four, with a mission to protect the biodiversity of the Sonoran Desert in southern Arizona through science-based advocacy, education, and collaboration. Their successes in protecting open space and advocating for wildlife crossings is largely due to their grassroots advocacy approach and the more than 60 active volunteers helping behind the scenes. Volunteers check wildlife cameras, sort wildlife photos, conduct roadkill surveys, help with outreach, and more.
New volunteers have joined since the pandemic began and, like college student Andres Martinez, are signing up family members to join them in the field, helping keep field teams within their own “social bubbles.” Other volunteers, like Patrick McGowan and Butch Farabee, are wearing masks and keeping social distance while they hike to check wildlife cameras as “Desert Monitors.” Some take their spouses along, or alternate field days with teammates. Staff deliver batteries and other field supplies on volunteer’s porches, rather than having people visit the office.
Jane “Middy” Henke is a “Desert Identifier” volunteer with the Coalition, who used to come into the office every Tuesday to sort and identify animals photographed by wildlife cameras. The Coalition changed over to a new database system so volunteers could work from home, with optional weekly virtual meeting hours to work together. “Now we can review the photos from our home computers to assign the species and number of animals we observe,” says Henke. “The current challenge for me is working out which type of skunk I may be seeing in a night photo, and maybe puzzling as to whether the nose appearing in the corner of a picture is that of a mule deer, or if it belongs to a white-tail deer!”
Volunteer Appreciation Week, from September 7 to September 12, was created as a virtual celebration to replace events canceled last April. “We want to recognize the significant impact our volunteers make, and thank them for their commitment as we shift procedures to address the effect the pandemic is having on them, and on their work doing wildlife studies,” says Executive Director Carolyn Campbell. “They are the backbone of our work.”
“More than ever right now I think people are looking for empowering and restorative things to do, ways to make a difference, and ways to connect,” says Moreno. “What we are seeing is really hopeful.”

Did you know that there are five wildlife underpasses that traverse Tangerine Road? These wildlife underpasses were finished in 2018 and the Arizona Game and Fish Department (AGFD) is now in the middle of a post-construction monitoring study of the crossings. In May 2020, AGFD released its latest monitoring progress report. We’re happy to report there were some very encouraging data and findings!
According to the AGFD report:
Data has been analyzed to April 7th, 2020. A combined total of 5,996 crossings by 23 wildlife species have been recorded across all 5 structures. Coyote, javelina, gambel’s quail, and bobcat constitute the most commonly recorded species with 3,002, 1,695, 482, and 403 crossings respectively, representing 93% of all documented crossings. Crossings of note include a gila monster at one underpass in April 2019, and a mountain lion at a different underpass in June 2019.
A total of 40 species have been detected across the five structures to date. The greatest diversity has been observed at underpass #2 where 29 species have been recorded. 16 species have been detected at underpass #1, which is the smallest monitored structure.
[Note: a species is “detected” when it is observed near the crossing structure. This is a different data point than documenting that a species successfully crossed through the structure.]
The full AGFD monitoring report can be found HERE.
Over the last year or so, we have expanded our work protecting Sonoran Desert wildlife linkages to the Rincon-Santa Rita-Whetstone Mountains wildlife linkage that is fragmented by Interstate 10 east of Tucson. 40 wildlife cameras are now collecting data in this wildlife linkage thanks to the amazing help of our volunteers and community partners!
A few updates to share:
*With our Desert Identifier volunteers that sort our wildlife camera photos currently on hiatus due to the Covid-19 pandemic, we have a backlog of photos waiting to be sorted at a future date. Jessica Moreno, our Conservation Science Director, is currently transitioning our sorting software and database to a remote platform. This will allow volunteers to access and sort photos safely from their homes! We are excited about this development and will let you know when the new system is up and running.
*So far, with the photos we have been able to analyze, we have photos of 11 different mammal species plus turkeys. This includes coyote, two species of skunk, fox, bobcat, bats, badger, mule deer, white-tailed deer, javelina, and opossum. See photos below for some of this amazing wildlife!
*This data is being used to develop a funding proposal with our community partners for the Regional Transportation Authority Wildlife Linkages Working Group. The proposal will be requesting funds to install wildlife fencing and complete culvert enhancements to make this wildlife linkage area safer for both wildlife and people.
Thank you for supporting the protection of Sonoran Desert wildlife linkages!
Arizona Game and Fish Department (AGFD) just released the latest and greatest monitoring data from the Oracle Road wildlife overpass and underpass. This represents FOUR FULL YEARS of monitoring these wildlife crossings since construction finished in March 2016.
Some notable data and results include:
- 26 different species have been observed using the crossings, including 11 species at the overpass and 25 species at the underpass.
- Over 10,000 wildlife crossings have been documented by AGFD cameras – 10,843 to be exact. These crossings are fairly evenly split between both structures, with 5,490 crossings at the overpass and 5,353 at the underpass.
- Over 98% of the crossings are by four species: mule deer, javelina, bobcat, and coyote.
- Total crossings at each structure have increased year upon year since construction finished. This means each year more and more wildlife are using these wildlife crossings.
For more results, you can read the full monitoring report HERE.

Thanks to a new partnership with volunteer, welder, and ecology student Raynor Vandeven, there are now four wildlife cameras out in the field with professional photography equipment capturing images of Sonoran Desert wildlife. These cameras are located in an area along the proposed I-11 route, in the Tucson Mountains, near the Oracle Road wildlife crossings, and in the I-10 East wildlife linkage area.
We are so grateful to Raynor for his willingness to share these images with the Coalition and can’t wait to start sharing more of them with you in the weeks and months ahead!
(Note: the photos below are examples of Raynor’s wildlife photography and were not taken in the locations described above. )
The Oracle Road wildlife crossings were recently featured on TV station FOX10’s Drone Zone segment in Phoenix. Check out this 3+ minute segment to see some amazing drone footage of both the Oracle Road wildlife underpass and overpass, along with a great interview of our partner Jeff Gagnon with the Arizona Game and Fish Department (click on the image/link below to access the full TV segment).
The short answer from our Conservation Science Director Jessica Moreno is:
I recommend checking out the reviews and the beginner’s buyers guide found at www.trailcampro.com. With new models coming on the market all the time, this is a great resource for up to date recommendations and tips. You get what you pay for, so I don’t recommend anything worth less than $100. To minimize animal disturbance, choose an infrared/IR camera over white flash.
For more information, check out Jessica’s longer article in the Desert Leaf, “Wildlife (caught) on camera” which gives more details on wildlife cameras, the different ways they are used, some rules and regulations to think about depending on where you’re placing them, and what to think about when buying one.
If you do end up buying a camera and get some interesting pictures of Sonoran Desert wildlife, we’d love to see them!
Note: Another fun resource is the Backyard Wildlife of the Southwest Facebook page where wildlife enthusiasts from around the Southwest regularly post photos of wildlife taken with their wildlife cameras and regular cameras.
Thanks to all of our supporters and volunteers for another year of successful wildlife camera monitoring in the Tucson Mountains and Oro Valley study areas! See an overview of our Tucson Mountain camera project results HERE and our Oro Valley camera project results HERE.
We have been monitoring wildlife with wildlife cameras in the northern portion of the Tucson Mountains and Avra Valley for four years. To date we’ve seen over 30 species across 23 camera sites, data which helps inform our I-11 work and knowledge about the Tucson-Tortolita Mountain Wildlife Linkage. Javelina have been photographed most frequently, and it is good to see these native seed dispersers out and about! Other notable results in the last year include more badgers, and bobcats with kittens in tow.
In Oro Valley, we have been monitoring east and west of the Oracle Road wildlife bridge and underpass for a total of seven years! We now have excellent comparative data pre- and post- construction of the crossings that were built in May 2016. With 62 species across 49 camera sites (and nearly 78,000 photos!), we are seeing lots of cottontails and quail that are plentiful prey for coyotes, bobcats, and gray foxes. We’ve seen white-nose coati and bighorn, and our resident female mountain lion has appeared again this year several times just west of the wildlife bridge.
We will post more detailed results as we finalize project reports and dive into the fun and useful information these cameras have in store!

Coalition staffer presents on I-10 Safe Passages Project at International Conference on Ecology and Transportation
By Myles Traphagen, Borderland Programs Coordinator, Wildlands Network
Sacramento, California was the location of the tenth biennial International Conference on Ecology and Transportation (ICOET) held September 22 to 26th, 2019. Jessica Moreno, the Coalition for Sonoran Desert Protection’s Conservation Science Director, presented the “Safe Passages for Wildlife on Interstate-10 within the Rincon-Santa Rita-Whetstone Mountains Wildlife Linkage” project, made possible by a generous grant from the Arizona Game and Fish Department Heritage Fund.
Nearly 600 delegates from 19 countries attended the four-day conference held at the Hyatt Regency directly across the street from the California State Capitol building. The vast array of topics at the conference ranged from camera trapping workshops, wildlife crossing structure design, public policy, and the state of transportation ecology around the globe.
With nearly 4 million miles of roads in the United States, and the ever-increasing paving of new roads globally (estimated to total 16 million miles by 2050), the effects of mechanized human transport on wildlife, biodiversity, and highway safety are staggering. The constant, daily stress exerted upon wildlife and biodiversity by roads cannot be ignored. The Coalition for Sonoran Desert Protection is actively addressing this issue through a variety of projects, and the Safe Passages presentation made by Jessica at the ICOET Conference was the final presentation in the Connecting Plans to Action session, for action is our modus operandi.
The 20-mile stretch of Interstate 10 between the Highway 83 and first Benson exit is the focus of our project. It’s obvious to anybody who has driven through this stretch that the numerous drainages and arroyos, like Davidson Canyon and Cienega Creek (which encompass several protected areas and important waters in the eastern Sonoran Desert), provide a natural travel corridor for animals that migrate between the Sky Island mountains north and south of I-10. This area has been a frequent zone of wildlife vehicle collisions. It’s no accident that these unfortunate “accidents” occur, because the Arizona Wildlife Linkages Assessment identified several wildlife corridors that cross right through here. This underscores the perils of the linear infrastructure like roads, railways, power lines and canals that increasingly dominate our modern world.
Now in Phase II, the I-10 Safe Passages project is using wildlife camera monitoring and roadkill surveys, along with community science engagement, to gather species-specific baseline data on wildlife passage rates and roadkill hotspots. We couldn’t do this important work without our dedicated volunteer team of “Desert Roadies” to help us with the driving surveys. Preliminary results, including a black bear mortality on August 23rd at mile marker 289 at Cienega Creek, have already begun to identify optimum locations for wildlife funnel-fencing installation, existing culvert retrofits, and new wildlife crossing structures. These data will inform State and County highway and wildlife officials on where to focus mitigation efforts to improve highway safety and minimize wildlife-vehicle collisions, and to provide justification for project funding.
In the US alone, it is estimated that there are between one and two million large animal wildlife vehicle collisions a year with hundreds of human fatalities as a result. The science of Road Ecology is attempting to reduce these occurrences by using crash analysis and GIS modeling of landscape variables that naturally funnel animals towards point specific places in their daily and seasonal movements. Progress is being made in identifying these places (like along I-10) where the greatest likelihood of wildlife collisions is predicted to occur.
With the data collected from the I-10 Safe Passages Project, we can identify and quantify wildlife vehicle collision hotspots and plan for and modify build-out plans to mitigate and respond accordingly to reduce these conflicts. In the case of the proposed Interstate 11, we support using avoidance and not building it in the first place! In the age of “Super-Commuters,” a term which the Director of the California Department of Fish and Wildlife used to describe drivers who spend two hours each way traveling to and from work, we need to rethink our approach to highway construction and proactively mitigate for and modify the design and building of roads.
