Honor Hector Conde with your gift today

Posted on:

This past winter, long-time conservationist Hector Conde passed away. Hector Conde (1930-2023) was born and educated in Buenos Aires, Argentina. Hector’s world view was influenced by his classical education; he spoke five languages and studied philosophy, mathematics, opera, art, and poetry. He was an engineer, an artist and an inventor who held dozens of patents.

His understanding of the factors that led to the decay and decline of past civilizations informed his concerns for our beloved Sonoran Desert and the animals who depend on this habitat for their survival. He saw modern policy through the lens of a poet, a historian, and often, a person who simply appreciated the bird songs and blooms in his own backyard.

Hector’s interests were varied and vast, but he was most focused in his later years on concerns about water and on establishing wildlife corridors for the species who live in the Tucson region. He helped collect and analyze data and map potential corridors to connect the Catalina Mountain range to the Tortolita Range. Today, this corridor offers a safe passage for multiple species that otherwise would have died out due to the development that has blocked their habitat.

In his memory, his friends and family have set a goal to raise $5,000 in support of the Coalition’s Desert Wildlife Internship program. So far, we have raised $1,613 in Hector’s memory. Can you donate today and support future conservationists through our internship program? Donations can be made securely at our website anytime: and mention “Hector Conde” in the note for your donation. Thank you!

SR77 Wildlife Gate and Fencing Ribbon Cutting Event

Posted on:

On April 19, 2023, the Town of Oro Valley hosted a ribbon cutting to celebrate the culmination of a years-long collaboration between the Town, surrounding neighbors and regional partners to preserve scenic views, fix fencing gaps, and protect wildlife along SR 77 near the wildlife crossings.


Pat Miller, a CSDP Desert Monitor volunteer and a local resident involved with the project, took this photo of the completed wildlife gate at Big Wash Overlook Place, one of two automatic gates installed near the wildlife underpass.


“This has been quite an effort on the part of groups with a wide variety of needs. Biologists, government agencies, and wildlife connectivity advocates were at odds with Oro Valley residents’ concerns about scenic views at the start of this project, with no solution seemingly possible. But collaboration won the day, with groups working literally for years to find a solution that works for both wildlife and residents. Today is a celebration of that effort,” said CSDP Executive Director Carolyn Campbell

About the project
The gate and fence project was funded by the Pima Association of Governments/Regional Transportation Authority (PAG/RTA). The Town of Oro Valley served as project administrator, with work done by AECOM, Sellers & Sons, Inc., Ninyo & Moore and Tucson Electric Power.

As part of the SR 77 road widening project improvements, game fences had been installed on both sides of the SR 77 corridor from Tangerine Road to the Pinal County line. In this area, a 10-foot-high fence was initially planned to be installed on the back side of homes along the Big Wash. This would route wildlife to the previously established SR 77 wildlife crossings. However, residents in the area expressed a desire to see wildlife from their homes, and not look at a tall game fence. The Town of Oro Valley and PAG/RTA worked with neighbors, Arizona Department of Transportation, Arizona Game and Fish Department and the Coalition for Sonoran Desert Protection to make changes to the existing fence and add gates across the roads to prevent wildlife from dangerously crossing SR 77, keeping wildlife in the Big Wash wildlife corridor.

“Oro Valley takes great pride in our natural open spaces and wildlife,” said Oro Valley Mayor Joe Winfield. “While building upon a previously established wildlife route, this project is truly a group effort to find solutions to protect wildlife without compromising our scenic views. We are grateful for the residents, conservation groups and regional partners who share our community’s values and collaborated with the Town of Oro Valley on this wonderful project.”

The SR 77 Wildlife Bridge was the first of its kind in Southern Arizona when construction finished in 2016. The bridge provides a safe crossing over SR 77 for wildlife including bobcats, desert tortoises and mule deer. One mile to the south, a large wildlife underpass provides another safe crossing point; the underpass is located adjacent to new wildlife gates and fencing. Regional conservation groups now monitor wildlife near the bridge and underpass using cameras.

“The wildlife fencing project has been ongoing since 2016 and has been a collaborative effort between the homeowners, the Town of Oro Valley, the RTA, the Coalition for Sonoran Desert Protection and the Arizona Game and Fish Department. The gates and gap wildlife fencing should serve well to protect animals from entering Oracle Road and to use the animal underpass. Congratulations to all for this wonderful outcome,” said Pat Miller, a resident who has been involved in this project.

Celebration of Life and Hike and Memorial for Josh Skattum

Posted on:

Please join us Saturday 3/4/23 at Sabino Canyon to remember and celebrate our friend and colleague Josh Skattum. We’ll walk in our tie-dyed shirts to the Cactus Picnic Area to gather and share our stories and favorite moments with Josh. Josh’s family will be joining us from Wisconsin and would love the opportunity to meet Josh’s Tucson community and hear more about his time in our lives.

The Coalition is putting together a scrapbook of his adventures with us to give to Josh’s parents. We invite you to bring a photo, trinket, or written story/memory you might have of Josh to add to this gift. Our goal is to give them a chapter of Josh’s, one they can enjoy again and again once they’re back home in Wisconsin.

After we gather for the memorial, we invite folks to hike back to the Visitor’s Center along the Esperero Trail or extend your time in the canyon with one of the many other trails available. Sabino Canyon was one of Josh’s favorite places and he visited to explore often, we couldn’t think of a better place to gather and celebrate him.

Pima County pursues new protected open spaces

Posted on:

Late last year, Pima County announced a slate of new protected open space acquisitions they are pursuing with the $2 million allocated for the acquisition of conservation land in the County’s 2022-2023 budget. The open space parcels include:

  • A set of parcels next to the wildlife crossing over the CAP canal in Avra Valley;
  • A set of private inholdings on the M-Diamond Ranch in the San Pedro River valley; and
  • A small inholding on the Buckelew Farm in Avra Valley. 

Want to learn more about these parcels? Head over to this Pima County memo that includes more details about each open space acquisition and maps of the parcels adjacent to the CAP canal wildlife crossing. 

All of these new open space acquisitions are part of Pima County’s continued implementation of the Sonoran Desert Conservation Plan

2022 Wildlife Camera Project Recap

Posted on:

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. 

Watch a presentation about this project here.

This happy coyote was photographed near the Oracle Road wildlife underpass by our CONFORTI camera, monitored by Pat & Henry Miller.


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.

Watch a video showcasing this area here.

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 latest on I-11: Lawsuit sees its first day in court

Posted on:

On Wednesday, January 25, 2023, U.S. District Judge John C. Hinderaker heard arguments on the federal government’s motion to dismiss a portion of our challenge to Interstate 11 filed in April 2022 in collaboration with the Center for Biological Diversity, Tucson Audubon Society, and Friends of Ironwood Forest. Big thanks to the 30 Coalition supporters that showed up to support us at the hearing.

According to a press release about the hearing, “The lawsuit says the agency failed to consider other transportation alternatives, such as rail, and sidestepped the required environmental review before approving the 280-mile-long highway between Nogales and Wickenburg. The planned interstate’s west option would plow through desert wildlands in rural Avra Valley and between Saguaro National Park and Ironwood National Monument. It would disturb hundreds of archaeological and cultural sites and spread invasive buffelgrass known to fuel wildfires.” 

You can learn more at at a KVOA4 story that aired after the hearing and a KGUN 9 story that aired before the hearing. We will update you when we learn more about a timeline for Judge Hinderaker’s decision on the case.

Whatever his decision, we remain grateful for your support as we continue advocating against the West Option for Interstate 11 and for a connected and restored Sonoran Desert in southern Arizona for all. 

Want to learn about the history of Interstate 11 and ways to get involved today? Head over to our comprehensive set of webpages (also found at the top of this page under the “Our Work” tab), including a history of the planning process, a thorough list of media articles,  maps, and more. 

SnapShot USA in full swing

Posted on:

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!

Kit Fox: CSDP Photographs Another First

Posted on:

By Jessica Moreno, Conservation Science Director

It’s late morning in early May when my phone buzzes with a text message from my friend and long-time Desert Monitor Josh Skattum. It’s a black and white photo from our “UTA” camera in the Tucson-Tortolita Mountain corridor, a blurry ghost of a fox with large, pointed ears and a small animal in its mouth, trotting swiftly through a moonless desert night. “Kit fox?,” Josh types. It looks plausible… I promise to look at it more closely and confirm.

The desert kit fox (Vulpes macrotis) has exaggerated features and could easily be included in a sci-fi wildlife field guide, fitting comfortably among the illustrations of banthas, sandworms, or tribbles. They are tiny canines, just 3.5 to 6 pounds, the weight of a full-grown Chihuahua. That small package comes with oversized 3- to 4-inch-long ears that helps dissipate the heat, a fluffy tail that nearly doubles its body length, and fur packed between their toes creating custom-made sand shoes.

Their soft sandy-colored coats are sometimes trimmed in bright rusty orange as if their edges were dyed by the desert sunset. In the moonlight, you might only glimpse pale fur and a black-tipped tail that doesn’t sport the signature bold black stripe found on the more commonly seen gray fox. But the kit fox’s delicate pointy face, bright eyes, and overlarge ears give them the same playful and mischievous countenance.

Several more nocturnal photos later, and I am more confident in my ID. Josh even documents a likely burrow site. Just to be doubly sure (and for fun), I ask for the help of Raynor Vandeven, a talented photographer who builds his own custom-made camera traps to produce incredible wildlife images. He sets out to see if he can get a more photographic image for us – with almost instant success.

These photos are the first time a kit fox has triggered one of the wildlife cameras we use to monitor the movement patterns of animals that use Pima County’s wildlife corridors. These areas tend to be the most threatened by roads and development – and also exactly the kind of low desert habitat that is preferred by kit foxes. And here they are, fulfilling their special role in the Sonoran Desert ecosystem as mesocarnivores.

A mesocarnivore is a small to mid-sized mammal that eats mostly meat (50 – 75% of their diet) but also eats other things – fruits, plants, fungi, insects – and is therefore an omnivore. Ecologically, they serve a role similar to the fewer-in-number large carnivores, like mountain lions, with some differences, such as spreading seeds that help plant dispersal, influencing disease dynamics, and being able to drive community structure (the types and number of species that live in a place and how they interact with one another). The disappearance of mesocarnivores on the landscape, both in abundance and diversity of species, is a canary in the mine for ecological health.

For their part, kit foxes primarily eat cottontail rabbits and rodents like kangaroo rats for their meat course. Very rarely they will eat the jackrabbits that complete with them for size. They will also eat carrion, birds, lizards, insects, quail eggs, saguaro fruit, prickly pear fruit, and mesquite beans. When food is plentiful, they might cache their meals by burying them, squirrel-like, and marking the spot with pee – a fox’s version of the office refrigerator lunchbox post-it note: My Lunch. Do Not Eat.

Kit foxes are solitary hunters and are often seen alone but are part of small family groups of parents and their young. Mates form a monogamous, permanent bond and both parents care for a single litter of 5 to 7 kits, or pups, that are born blind in March and April and remain in their cool den, with its keyhole-shaped entrance, until the monsoon arrives in June or July.

They can find food and mates, raise young, and disperse surprisingly long distances to new habitats – despite the challenges of mange caused by rodenticides, canine distemper and rabies, and the very pressing concerns of habitat loss, habitat fragmentation, and wildlife-vehicle collisions. Time will tell if rising temperatures and other threats prove too much, or are averted too late, for a species that has been with us since the Great Ice Age and survived the extinction of the larger Pleistocene megafauna.

Today these tiny, playful desert den dwellers are considered vulnerable in Arizona but do not have any protected status. Their distribution is extensive throughout the Great Basin, Sonoran, and Mojave deserts, but populations have generally been declining by 10-30% across their range, according to data collected on NatureServe. A fox to watch. 

Our nocturnal kit foxes continue to bless the desert night with their yips, barks, and chuckles. Tonight, I allow myself to imagine that they sometimes gaze up at the stars, above the haze of nearby city lights and horizon of creosote, stars that for untold generations have been their only constant. The chuckle in the dark desert night I hear sounds like an echo of Josh’s laugh.
