P-22 is a famous mountain lion that helped inspire the construction of the massive Wallis Annenberg wildlife crossing over the 101 Freeway in Los Angeles. After the passing of P-22, lifelong wildlife advocate, Beth Pratt has worked to spread awareness of the importance of wildlife crossings in urban spaces, saying, “The most fitting memorial to P-22 will be how we carry his story forward in the work ahead. One crossing is not enough – we owe it to P-22 to build more crossings and connect the habitats where we live now.”
This brings them to their current mission and journey: exploring 11 wildlife crossings across America and sharing with the world the possibilities of creating safe passages for wildlife. Among Beth’s team is National Geographic photographer Steve Winter, writer Sharon Guynup, and ARC Solutions’ Renee Callahan and Marta Brocki, who we had the honor of meeting during their visit to the first wildlife bridge in the Sonoran Desert on September 16th, 2023.
The Oracle Road wildlife crossings, both a bridge and underpass, were constructed in 2016 to increase wildlife connectivity between the Catalina and Tortolita Mountains. It was a pleasure to share our success story with them and we are honored to have been a part of their journey!
You can see a video of our field trip to the Oracle Road wildlife bridge at this Facebook post.
Last month we shared that we expanded this project in 2022, with cameras on either side of I-10 between the Tucson Mountains and Tortolita Mountains, and six more planned to be placed in 2023. Here are some details on what we’ve found so far!
Our project is comparing five study areas, each with four cameras placed at least 200m apart. These areas are shown in the map below: Private lands in the northern Tucson Mountain range (1), Los Morteros & Rattlesnake Pass (2), El Rio Preserve (3), the Santa Cruz River (4), and Pima County Conservation lands east of Interstate 10 called Cascada (5). These study areas make up a large part of the Tucson-Tortolita Wildlife Linkage, and each has different topography, elevation, distance to water, and other unique habitat features.
Our results show that each study area is dominated by different species, but there are common species throughout, namely mule deer, coyote, bobcat, javelina, gray fox, and cottontail rabbit. Mountain lions have only been observed on Private lands, while kit fox and badger have only been photographed on Cascada lands. El Rio is thus far the least diverse in species (it is also the smallest area and the most impacted by people), while Private lands have been the most diverse – unless you count individual bird species, and then the Santa Cruz River area has them all beat. In addition to the exciting kit fox discovery, other notable species include hooded and spotted skunks, raccoon, and Mexican free-tailed bats.
Working with Pima County, this data is already informing a project to build a wildlife ramp from the only accessible wildlife crossings near Avra Valley Road, to provide entry into the Santa Cruz River over the water levy. We are also working on gaining permanent protection for the Tortolita Preserve and planning a large wildlife bridge over I-10, and a smaller crossing structure at Rattlesnake Pass. These crossings are being designed specifically with mule deer, mountain lion, and bighorn sheep in mind, but will benefit many species.
Thank you to all of our volunteers that are instrumental to this work and to our many member groups and community partners that are collaborating on this multi-pronged project!
2022 was another successful year for our Wildlife Camera Monitoring Program, and also our 10th anniversary of this community science-based project! Big thanks to ALL the volunteers that have been the engine behind this project from day one!
Oro Valley Linkage Wildlife Monitoring
This is the project that started it all, and gives us the distinction of having the oldest and longest lasting community science wildlife camera monitoring effort in southern Arizona. Today we have 24 active cameras on either side of Oracle Road, that have gathered over 300,000 images of wildlife, including a mountain lion who moved through the underpass this year. We have also identified 24 wildlife species in this area, with the addition of a black bear this past year.
Tucson Mountains Linkage Wildlife Monitoring
We have expanded this project this year, with 24 cameras on either side of I-10 between the Tucson Mountains and Tortolita Mountains, and 6 more planned to be placed in 2023. These cameras have captured nearly 124,000 wildlife photos over the life of the project! We have also identified 26 different wildlife species in this area, with the addition of the kit fox this past year.
Working with Pima County, this data is already informing a project to build a wildlife ramp from the only accessible wildlife crossings near Avra Valley Road, to provide entry into the Santa Cruz River over the water levy. We are also working on gaining permanent protection for the Tortolita Preserve, and planning a wildlife bridge over I-10 and another at Rattlesnake Pass.
Sopori Ranch Linkage Wildlife Monitoring
In partnership with the Arizona Land and Water Trust, we are monitoring this linkage and using the images to promote this wild corridor. Today we have 5 cameras that have produced nearly 4,000 images and growing.
I-10 East Linkage Wildlife Monitoring
The I-10 East project involved two seasons of roadkill surveys and two years of monitoring key culverts and bridges for wildlife use and passage rates. Exactly 45 wildlife cameras were active between January 2020 and January 2022, during which time we collected over 789,000 photos and have identified over 36 species across our 10 monitoring sites, including both mule deer and white-tail deer, Mexican opossum, black bear, mountain lion, Gould’s turkey, white-nose coati, ringtail, striped skunk, hognose skunk, hooded skunk, Western spotted skunk, and badger.
Interesting records included a photo of a bobcat carrying a bull snake in its mouth, the Mexican opossum, and images of a likely mating pair of adult mountain lions traveling together.
This data report is being incorporated into a proposal for wildlife funnel fencing and improved underpass and bridge structures for wildlife. Pima County is also using this data to justify a funding grant to make surface water improvements near these sites, and we collaborated to submit scoping comments in October 2022 for an upcoming ADOT project to help improve the area with highest roadkill mortality in our roadkill study between mileposts 292-294.
The Snapshot USA project is a huge collaborative effort to sample mammal populations with camera traps across all of the United States. The study is designed to sample sites in all 50 states stratified across habitats and development zones (suburban/rural/wild/urban) with an objective of at least 400 “trap nights” (or days) per sub-project/ organization.
This year we were able to contribute camera data from 12 cameras in our Oro Valley study area, for the study period of September and October.
Despite a few challenges with vegetation growth creating lots of blank images, we contributed 3,208 photos of species including javelina, jackrabbits, coyotes, bobcats, mule deer, white-tail deer… and even a surprise black bear on the MALLOW camera! The entire effort has collected photos of 384 species at over 2,000 camera sites across the U.S.
As science papers come out of this data, we will share the results and findings with you, and we look forward to contributing again next year!
On Saturday November 19th, 46 participants made almost 700 observations of over 135 species!
The first Tortolita Preserve BioBlitz was a huge success! What a great way to share and explore this amazing open space!
We held seven small group outings during the BioBlitz, and all the participants enjoyed getting a chance to explore with guides from Arizona Master Naturalists, Arizona Game and Fish Department, the Coalition for Sonoran Desert Protection, and Tortolita Alliance. One of the guided walks headed by CSDP’s Jessica Moreno focused on identifying animals by scat and tracks. Species identified included Grey Fox, Mule Deer, Bobcat, Coyote, and even the tiny and industrious Kangaroo Rat! Another walk conducted by Jennie McFarland from Tucson Audubon Society and Steven Prager from Audubon Southwest yielded a list of fifteen species including a Ruby-crowned Kinglet; the first time this species has been documented here on E-Bird. Another highlight was the identification of Gregg’s Nightblooming Cereus happily existing in the understory of a Palo Verde.
In addition to the outings, many people worked hard collecting observations on their own. We had several people visiting the Tortolita Preserve for the first time and others new to iNaturalist making a big contribution to the success of the event. Identifying observations made by others is another area in which our group really contributed. We had people making identifications during the BioBlitz. This is such an important part of the outreach component of iNaturalist, so a big thanks to people who worked on identifications!

Join us this week to remove old fencing and improve wildlife connectivity between the Tucson Mountains and the Tohono O’odham Nation!
This past December, over 65 volunteers came together one morning to remove three miles of old fencing, including three tons of fence posts and wire fencing, from an area in Avra Valley west of the Tucson Mountains. Removing this fencing is important to improve the critical wildlife linkage areas between Tucson Mountain Park, Saguaro National Park, Ironwood Forest National Monument, and the Tohono O’odham Nation. And now this collaborative project is moving forward with another opportunity to pitch in and remove even more fencing!
When: Thursday, Friday, and Saturday – March 10, 11, and 12
Time: 8am-12pm, 12pm lunch (will be provided), Afternoon flexible
Where: Avra Valley area near Three Points (more detailed instructions on exactly where to meet will be sent out to volunteers after they sign up)
What to bring: Water bottle, work gloves, sturdy shoes, sun hat, etc. (again, more details to follow)
How to sign up: Head over to this GoogleForm to sign up
According to Don Swann, a biologist at Saguaro National Park, “Many studies have shown that barbed wire fences can stop large animals, change their movement patterns, and keep them away from water and food sources they need to survive. Animals can also be killed trying to jump over a barbed wire fence if they become entangled and are not able to free themselves.”
You can sign up for one, two, or all three days! All you need to do is sign up through our online form.

Good news for conservation in Marana!
On December 10, 2019, the Marana Town Council approved the new draft Marana General Plan with a few major changes we requested. This includes 1) solidifying the long-term protection of the Tortolita Preserve and 2) removing a “Special Planning Area” from lands southwest of the Tortolita Preserve so these lands will remain low density if they are ever developed.
Thank you to all the community members that showed up and voiced their concerns about these issues over the last couple months, including the newly formed Tortolita Alliance! Our voices can make a difference!
If you’d like more information, you can read our full comment letter that we submitted to the Marana Town Council on December 9, 2019 and our previous comment letter submitted to the Marana Planning & Zoning Commission in September 2019. The full draft Marana General Plan is available on the Make Marana 2020 website.
What’s next for the Marana General Plan? Marana voters will get to vote on this new General Plan in August.
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.
