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.

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.

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!

The first Tortolita BioBlitz was a huge success!

Posted on:

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!

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.

Pima County’s Open Space Conservation Acquisitions: An Overview 

Posted on:

Pima County has invested heavily in acquiring conservation properties, especially in fulfilling the goals of the Sonoran Desert Conservation Plan. The County recently released a new report about all their open space conservation acquisitions.  Along with providing a comprehensive overview of this decades-long program, the report specifically touches on the transparent public processes underlying the prioritization of eligible lands, funding mechanisms, and benefits these lands bring to the community.

This map from page 13 of the report shows the full suite of conservation lands in Pima County, including the open spaces owned or managed by Pima County in green and open spaces owned or managed by other jurisdictions (such as the Forest Service, National Park Service, etc.) in yellow.

Thank you for supporting our work as a partner and advocate for connected and robust protected open space in the Sonoran Desert! 

Reducing Roadkill: Safe Passages for Wildlife on Interstate-10 East

Posted on:

By Jessica Moreno, Conservation Science Director

One of the best things about doing roadkill surveys is watching the sunrise. During the monsoons, the sun breaks across the eastern horizon and lights up the moisture laden air and morning cloud cover with light and throws the foothills into brilliant color. The sun feels hopeful and the day new. The second-best thing is knowing that every datapoint is helping us make things better.

The 20-mile stretch of Interstate-10 (I-10) between Vail and Benson, east of Tucson, Arizona, divides the regionally important Rincon-Santa Rita-Whetstone Mountains Wildlife Linkage. This wildlife pathway is one of only a few – somewhat safe – crossing points across I-10 found between Tucson and New Mexico, and it encompasses several protected areas and important waters, including Davidson Canyon and Cienega Creek, making it critically important for desert wildlife in the face of climate change.

 

Thanks to aerial support provided by LightHawk, in February 2020 we were able to take to the air and photograph the project study area. The above photo is a view of the Rincon Mountains to the north with Cienega Creek and I-10 in the foreground. The Cienega Creek bridge, on the far center right, is one of the project’s wildlife camera monitoring sites, and cameras have been placed at each of the tributary drainages where they cross I-10. Roadkill surveys stretched from SR 83 to SR 90. Photo by Jessica Moreno, CSDP.

 

This wildlife pathway is protected partially by federally protected lands including Saguaro National Park, Rincon Wilderness, and Las Cienegas National Conservation Area. Pima County has invested in securing additional conservation lands in this linkage as mitigation under the Multi-Species Conservation Plan (MSCP), including Bar V Ranch, Cienega Creek Natural Preserve, Rancho Agua Verde, and Colossal Cave Mountain Park, which are managed under the Cienega Creek Management Plan.

However, I-10 cuts through this area of wildlife movement, resulting in more wildlife-vehicle collisions for large animals such as black bear, mule deer, whitetail deer, javelina, coyote, and mountain lion, as well as smaller species like box turtles, opossum, Antelope jackrabbit, white-nose coati, raccoon, badger, and bobcat. It also serves as a potential movement area for jaguars and ocelots. Existing culverts and right of way fencing are not currently adequate at reducing wildlife-vehicle collisions or ensuring safe wildlife passage in this area. Future growth and increases in traffic volumes will only worsen the frequency of vehicle-wildlife collisions.

Since 2006, several qualitative assessments and reports have been produced that highlight the area’s importance for wildlife movement, but there has not been a study that has collected data to build a high accuracy model of wildlife movements and roadkill locations along this corridor. With the lack of such a product, nothing has been done on the ground to reduce wildlife-vehicle collisions and to improve safe wildlife passage by employing effective mitigation structures like winged highway fencing or wildlife overpasses. The Coalition for Sonoran Desert Protection, in conjunction with partners, is spearheading the effort to collect data to provide the information necessary to make this stretch of I-10 a safer passage for both wildlife and people in this important corridor.

 

Raynor VanDeven captured this photo of a mule deer near one of our culvert study sites under I-10, just east of Davidson Canyon, with bright tail lights on the highway above appearing to streak across the night sky. He uses a custom built wildlife camera trap to gather these professional photos. Raynor’s work has been a tremendous contribution to this project!

 

In the spring of 2017, CSDP conducted comprehensive assessments and wildlife surveys of the nearly 80 existing concrete box culverts and metal plate pipe structures between milepost 277-302 (Houghton Road to SR90), with participants from several government, nonprofit, and community partners, including the Arizona Game and Fish Department, Cochise County, Pima County, Tucson Audubon Society, Sky Island Alliance, Defenders of Wildlife, and the Wildlands Network. Our results indicated that this wildlife linkage could be made safer for wildlife and motorists by 1) installing wildlife funnel-fencing to keep animals off the highway and to direct wildlife toward existing crossing points; 2) retrofitting and widening existing drainage culverts located in high volume areas; and 3) construction of an additional wildlife crossing between Cienega Creek and the railroad underpass near Empirita Rd Exit 292.

Roadkill surveys were part of the next phase of this effort: to gather data on roadkill hotspots, together with wildlife passage rates using wildlife cameras in the best existing culverts. We hope this 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 with site-specific wildlife funnel-fencing installation, existing culvert retrofits, and new wildlife crossing structures. Our results illustrate the need to implement changes and provides baseline information to evaluate the success of future mitigation measures.

Our Desert Roadies project began with a team of volunteers to help collect wildlife-vehicle mortality data on Interstate-10 between SR83 and SR90, east of Tucson. Desert Roadies volunteers worked in teams of 2-4 people, including myself, to conduct driving roadkill surveys. Observations were recorded by our notetaker with the GPS coordinates. Surveys were conducted in the morning, starting up to 30 minutes before sunrise, every week for 6 weeks during the monsoon season in 2019 and 2020, beginning in July, except when conditions were bad for visibility or driving such as rain, dust storms, or other low visibility weather. In addition to these formal roadkill surveys, we collected other data on iNaturalist.org from community members and personally investigated reports about black bear mortalities. We also requested ADOT records on reported animal-vehicle crashes in the study area. This data was analyzed separately.  

Due to the onset of the Covid-19 pandemic in March 2020, carpooling with volunteers was no longer a safe option. So, we adapted as best we could by canceling the planned spring 2020 survey and having another monsoon season survey instead, which was conducted by myself and my family, Eddie Moreno (who is also a biologist experienced in roadkill surveys) and my two toddlers munching on donuts and “helping” look for animals from the backseat. This survey was done when the state was under curfew and lockdown, resulting in reduced traffic volumes. This likely was one reason for fewer observations of roadkill during this survey window.

Walking surveys are the ideal method for complete and accurate data. But safety concerns eliminated that option because we are using volunteer participation and this is a busy interstate highway with narrow right of ways. Therefore, the roadkill survey portion of this project was designed to be a broad-brush stroke only and we anticipated a small sample size. Recording categories of small, medium, large animals and/or by clade (reptile, bird, small/med/large mammal) are adequate for our purpose. Because of the project design, we have near zero detectability of small animals, and instead our target species are deer, bear, coyote, bobcat, gray fox, javelina, and those larger animals that the Arizona Department of Transportation consider most hazardous to drivers. The data will hopefully serve to provide a preliminary look at potential roadkill hotspot areas. For best accuracy 1) our GPS units had a one-button click to mark points quickly, 2) volunteers could also use maps and mileposts to confirm locations, 3) we analyzed the data in 1-mile segments, which better informs the fencing solution strategy and somewhat addresses imprecise location information, and 4) a staff biologist was always present to provide corroborating identification.

We completed two monsoon survey seasons for roadkill observations in 2019 and 2020, resulting in 78 data points of at least 14 different species. We were able to detect animals as small as a rock squirrel or cottontail rabbit. Skunks, raptors, and deer were not identified to specific species. All of our deer mortality observations (n=2) occurred between mileposts 296-297, near the Pima-Cochise County line. A hotspot of roadkill observations occurred between mileposts 291-295 (between Cienega Creek and Empirita Rd), in an area that coincides with a gap in available culverts and crossing points, and near several culvert locations between mileposts 283-287.

Coyotes, cottontail rabbits, and javelina were the most abundant roadkill species observed during our surveys. We also observed skunks, badger, opossum, raccoons, mule deer, jackrabbits, gray fox, domestic dogs, and raptors. Our 2020 monsoon survey occurred during a state lockdown at the beginning of the Covid-19 pandemic, and less traffic may be one reason for the reduction of roadkill during this survey period. Bruce Jacobsen created this “heat” map showing hotspots of our observations.

 

Our roadkill survey results for 2019 and 2020 monsoon survey seasons show hotspots around culverts east of Davidson Canyon, including an eastbound lane culvert that opens up to the median without a way across the westbound lane at milepost 285. Another larger hotspot appears between Cienega Creek and Empirita Road, which coincides with an area absent of available culverts for wildlife to use as crossing points.

 

The Arizona Department of Transportation (ADOT) collects crash records from police reports of vehicle crashes. Vehicle crashes caused by “animals” in recent years align with where we are seeing larger animals (deer, black bear) being hit most frequently on the interstate. Crash records can help make the case for increasing human safety by improving safe passage for wildlife – in addition to the goal of protecting healthy wildlife populations.

 

I-10 has been identified as a significant barrier to black bears in southern Arizona. In 2011, Todd Atwood et al published a study describing I-10 as a more significant barrier to functional gene flow for black bears than the U.S.-Mexico border, identifying I-10 as the dividing line between the Border subpopulation of black bears to the south, and the White Mountain subpopulation to the north. In our study area, these subpopulations meet and Romeo and Juliet romances unfold, ensuring healthy black bear populations in Arizona and in Mexico. For black bears, I-10 may be a barrier to gene flow as well as a “population sink” due to wildlife-vehicle deaths. This could pose a significant issue for the Border subpopulation, which additionally faces barriers to movement at the U.S.-Mexico border due to the construction of the border wall and other border-related infrastructure such as roads and lighting. Without safe passage both north of I-10 or south of the border, our southern Arizona black bears are at risk of genetic isolation and disappearing all together (what we call extirpation).

We have gathered four records of black bear mortalities in recent years, and three of these are verified with photos. These records indicate that the bears attempted to cross I-10 by following higher elevation ridgelines closely associated with the two largest underpass structures at Davidson Canyon and Cienega Creek. We also have animal track and camera trap data showing successful passage under I-10 at a few specific culverts. Most of our observations show bears moving south. April-May and August-September appear to be peak periods of activity for black bears in this area according to our data.

Black bears are just one example of the impact I-10 is having on native wildlife. In addition to large animals like bear, deer, and jaguar, smaller animals are at risk as well. Saguaro National Park has been monitoring a disturbing decline in “lost carnivores” over the last decade, including skunks, foxes, and badgers. Biologists are also concerned about the local disappearance of smaller range habitat specialist species affected by habitat fragmentation, including box turtles, Antelope jackrabbits, skunks, kit foxes, badgers, and white-nose coati. Increasing wildlife connectivity conditions for black bears and deer should allow struggling populations to repopulate from connected habitat areas and also benefit a wide array of other species.

In addition to our roadkill survey data, we were also able to collect four records of black bears killed by vehicle collisions in our study area. Bear roadkill occurred near mileposts 285 and 289-290, associated with the higher ridge lines close to Davidson Canyon and Cienega Creek. Deer collisions, on the other hand, were largely occurring near mileposts 296-297, where the landscape is naturally flatter.

 

With the data we’ve collected, we have solid evidence to back up the need for funding wildlife funnel fencing where it is most needed and make the case for new or improved wildlife crossings.

Want to help?

Although collecting information on roadkill is not for the faint of heart, the data it provides is valuable. In the future, CSDP will be looking to continue our Desert Roadies program in more areas. In the meantime, folks can also document sightings of wildlife on roads in Pima County at https://www.inaturalist.org/projects/csdp-safe-passages.

Join us in removing old fencing and improving wildlife connectivity in Avra Valley!

Posted on:

Join us this week to remove old fencing and improve wildlife connectivity between the Tucson Mountains and the Tohono O’odham Nation!

Background

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!

The details

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.

Avra Valley Fence Removal Volunteer Day a Big Success!

Posted on:

On December 11, 2021, a group of local organizations and state/federal agencies came together to celebrate National Public Lands Day by holding a Fence Removal Volunteer Day in Avra Valley. It was a wonderfully cool day with volunteers in high spirits to accomplish something tangible and positive for wildlife. 

A few fun stats from this great event:

  • Over 65 volunteers, a group from the American Conservation Experience (ACE) program, and staff from Arizona Game and Fish Department and the National Park Service joined together for the project. 
  • 3 miles of fence were removed from the landscape in one morning.
  • 3 tons of metal, including fence posts and wire fencing, were hauled away.

This is a fantastic start to improving the permeability of the landscape for wildlife movement between the Tucson Mountains, Ironwood Forest National Monument, Pima County open space lands, and more. And a big thanks to the Coalition volunteers that came out and volunteered their time – we are so thankful for you. 

This is the first of a few Fence Removal Volunteer Days – we plan to hold one to two more this winter and spring so keep your eye out for more details. We’d love to have you join in on the next event! 

Thank you to all the organizations that helped make this event possible, including Friends of Ironwood Forest, Coalition for Sonoran Desert Protection, Saguaro National Park/National Park Service, Arizona Game and Fish Department, American Conservation Experience, Pima County, U.S. Bureau of Reclamation, and the Mule Deer Foundation.
