What types of wildlife cameras do we use?

Posted on:

Interested in purchasing a wildlife camera for yourself or as a gift for family or friends? 

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. 

The latest numbers from our wildlife camera program

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

Posted on:

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. To learn more about how you can help by volunteering or donating, visit us here. Keep an eye out for wildlife and drive slower, safer and less when you can.

Monitoring results from the Tangerine Road wildlife crossings

Posted on:

 

Did you know that there are now five wildlife underpasses under Tangerine Road?

As part of a larger project to improve Tangerine Road, five existing drainage structures were enhanced and improved to better accommodate safe wildlife movement across this popular roadway. This is a cost-effective way to increase connectivity across roadways that is less visible to the general public (as compared to a wildlife bridge) but still very important. Construction was completed on these wildlife underpasses in Spring 2018 with the cooperation of the Town of Marana, Pima County, the Regional Transportation Authority (RTA), Arizona Game and Fish Department (AGFD), the Coalition for Sonoran Desert Protection, and other members of the RTA’s Wildlife Linkages Sub-Committee.

Starting in 2010, the AGFD completed pre-construction monitoring using roadkill surveys. After the underpasses were completed in Spring 2018, the AGFD started a 3-year post-construction monitoring project, including roadkill surveys and monitoring wildlife use of the crossings using wildlife cameras. According to an April 2019 progress report from AGFD:

Between May and September 2010 5,152 road mortalities representing 88 species were documented, helping to identify hot spots for future implementation of fencing and wildlife crossing structures.

[Using this data], the objectives of this construction project were to:

  • Increase the size of five drainage structures and modify inlets/outlets to accommodate medium-sized mammals.
  • Add funnel fencing at the crossings.
  • Conduct habitat establishment evaluations, for three seasons, beginning one year after project completion, to determine whether any adaptive management measures are necessary to improve the effectiveness of the wildlife crossing structures.

Post-construction roadkill surveys began in Spring 2019. An April 2019 progress report primarily includes data from wildlife cameras installed on the underpasses and can be found HERE. A few data points and photos from the report are highlighted below:

Data has been analyzed to January 7th, 2019, this represents two full months of monitoring data for all five structures. A combined total of 1049 crossings by 17 wildlife species have been documented across all 5 structures to date. Coyote, javelina, and bobcat constitute the most commonly recorded species with 475, 365, and 130 crossings respectively, representing 93% of all documented crossings.

Mule deer and coyotes have both successfully crossed Tangerine Road safely using five new wildlife underpasses. These underpasses were created by enhancing existing drainage structures using voter-approved money from the Regional Transportation Authority’s wildlife linkages infrastructure funds.

This is exciting news for wildlife in the Tortolita Fan and motorists along Tangerine Road. With the inclusion of wildlife fencing on either side of these five underpasses, wildlife are now being funneled to cross Tangerine Road under the roadway, leading to increased safety for wildlife and motorists.** We will share new monitoring results from AGFD when they release their next progress report on this project sometime in the next year. 

Thank you for supporting connected wildlife linkages and wildlife habitat! 

**Some observant community members have noted that this wildlife fencing is shorter than the wildlife fencing along Oracle Road. Why is this? The Tangerine Road wildlife fencing was designed for the medium-sized mammals that are most likely to use these smaller culvert wildlife crossings. 

Badger, badger! New badger photos and data from our wildlife cameras

Posted on:

For 10 years we have had wildlife cameras on the landscape monitoring important linkages. We first captured photos of badgers in 2012, and they have made consistent, if rare, appearances since. Badgers are an understudied animal in Arizona and we know very little about their status in Pima County. We now have a total of 40 images of badgers across 19 camera sites, with a 27% occupancy rate (the number of cameras that detected badgers versus the total number of cameras out there). We have seen badgers at two sites in the Tucson Mountains study area, and at 8 and 9 sites West and East, respectively, of Oracle Road in Oro Valley. Our partners at Arizona Game and Fish Department confirm that one of the badgers we photographed crossed the wildlife bridge, moving east to west, earlier this year. We are diving into the data to learn more about them in our Sonoran Desert landscape, including a fun look at identifying individuals!

We thought you would enjoy these photo highlights, and a neat look at our preliminary results showing more badger activity during new moon nights than full moon nights. Why do you think badgers might be more active on new moon nights than full moon nights, when it is darkest? Badgers are nocturnal, although females may come out in the day with her young in Spring. They are also fossorial carnivores, meaning they live most of the time underground and are very good diggers. Most of their prey live in burrows as well, including ground squirrels, pocket gophers, packrats, kangaroo rats, and rattlesnakes. Badgers may be appearing on our cameras more often during the new moon for a variety of reasons. One possibility is that badger activity is correlated with prey activity, and conditions that increase hunt success. Are rodents are more active during the dark new moon than the brighter full moon, too? Can badgers, adapted to hunting at night and underground, sense their prey better on dark nights? In science, the best answers lead to more questions!

Many thanks to Pat and Henry Miller for contributing three badger photos from their own camera to our study.

If you haven’t heard it, you may enjoy Petey Mesquitey’s song “The Coyote and the Badger” on KXCI radio!

 

This graph shows how our wildlife cameras have captured more badger activity during new moon nights than full moon nights. Fascinating!

CSDP and the Oracle Road wildlife crossings featured on national news!

Posted on:

On Saturday, April 27, a new show on NBC, “1st Look,” aired a segment after Saturday Night Live about the Coalition and our work on the Oracle Road wildlife crossings. Coalition Conservation Science Director Jessica Moreno spent a long day in the field with the crew and host of the show, Johnny Bananas, in mid-March showing them the Oracle Road wildlife crossings, looking for a collared mule deer, tracking down a tortoise outfitted with a radio telemetry device, showing off one of our wildlife cameras, and more. Scientists from Arizona Game and Fish Department joined us for part of the day, along with Coalition volunteer and superstar Kathie Schroeder and her hawk Sueño. You can view the full 6-minute segment HERE or by clicking on the image below.  

And a huge thank you to all our community science volunteers and supporters that have been instrumental to this project and volunteer program! 

2019 Critter Cam Field Day a success!

Posted on:

Coalition volunteer Craig Civalier leads a group of elementary school children on a guided hike to learn more about Sonoran Desert wildlife at Catalina State Park in March 2019 during our second Critter Cam Field Day for Kids.

 

In early March 2019, the Coalition’s second annual Critter Cam Field day took place at Catalina State Park, serving over 400 local children. Thanks to an amazing team of volunteers, the activities went off without a hitch! Coalition volunteer Craig Civalier wrote the poem below in celebration of the day – thanks so much Craig!

 

Critter Cam Day

The kids were good today,

Buzzing round like bees,

Ran out of pencils,

Borrowed my pen,

 

Burrows in C4, ha-ha,

Microclimate close to the ground,

Water in D3,

Invasive species on the trail,

 

On to the critter cameras

Funny faces for evermore,

Weathered rock in C2,

Crumbled in your hand,

 

Butterflies keeping score,

This tree is your family,

Praying mantis ponds,

Scattered in the bush,

 

Handed thank you notes,

By three young girls,

Please take up science,

And save the planet.
