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.

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.

New Game and Fish monitoring report documents over 4,400 animals using Oracle Road wildlife crossings in first 2 years

Posted on:

The Arizona Game and Fish Department recently released their latest monitoring report on the Oracle Road wildlife bridge and underpass. Game and Fish is in the middle of four years of post-construction monitoring of these wildlife crossings. According to the report, as of June 2018, 2,477 animals have used the wildlife bridge and 1,941 animals have used the underpass. The most common animals to use the bridge are mule deer, whereas the underpass sees a lot of javelina and coyote. One interesting finding is that with time, more mule deer are using the underpass as they become acclimated to it. Other notable species seen in smaller numbers include bobcats, white-nosed coati, raccoons, and skunks.

Game and Fish also continues to monitor a large group of desert tortoises on either side of the crossings with radio-telemetry devices attached to the tortoises’ shells. While none of these tortoises have been documented using the crossings yet, we are hopeful that eventually they will.

Check out some new photos taken on the crossings from Game and Fish below. You can also view the full monitoring report here.

It was chilly outside in Flagstaff, AZ this February, when we presented our most recent wildlife camera results at the 2018 Joint Annual Meeting of the Arizona and New Mexico Chapters of the Wildlife Society. Inside, the conference rooms were toasty warm – and when our Programs Manager Sarah Whelan took the stage it was to a packed house. Professional biologists and students of wildlife from across two states were there to hear her 15-minute presentation on “Monitoring the Effectiveness of Wildlife Crossings in a Rapidly Developing Sonoran Desert Ecosystem.” In addition to the data and scientific process, Whelan highlighted the citizen science component and community engagement that made the project so successful. The two proceeding talks were led by well-respected wildlife corridor gurus Dr. Paul Beier, and Norris Dodd! We were in grand company. Also at the conference, we co-hosted a day-long workshop on wildlife camera monitoring, training participants in camera deployment strategies, study design, and sharing image management software resources.

 

Our full abstract can be read below:

Monitoring the Effectiveness of Wildlife Crossings in a Rapidly Developing Sonoran Desert Ecosystem

The Tucson-Tortolita-Santa Catalina Mountains wildlife linkage in Tucson, Arizona is one of the most threatened in the state. In response, Pima County and partners constructed a large wildlife bridge and a wildlife underpass across State Route 77, which bisects the linkage, in 2016. The Coalition for Sonoran Desert Protection is supplementing Arizona Game and Fish Department’s four-year post-construction monitoring efforts with a pre- and post-construction wildlife camera participatory research monitoring study, focusing primarily on mammal species. Our objective is to develop a baseline and monitor changes in species richness and wildlife activity patterns in the study area. In addition, the project’s goals include close collaboration and data sharing with partners, and to engage and train local residents as citizen scientists. We are using the data management and analysis protocols developed by Sanderson & Harris 2013. To date, we have collected 3 years of pre-construction data and two years of post-construction data, with 41 cameras deployed throughout the linkage, including 11 cameras at the wildlife crossing approaches, monitored and managed by 56 citizen science volunteers. No bait is used. We found 44 species, including notable records of American badger (Taxidea taxus), white-nosed coati (Nasua narica), and desert bighorn (Ovis canadensis nelson). Preliminary results also suggest increased mule deer (Odocoileus hemionus) activity west of the crossings post-construction. We continue to gather data to help inform adaptive management needs as wildlife fencing gaps are addressed, and to highlight the effectiveness of wildlife crossings in a rapidly developing Sonoran Desert ecosystem.

In the News: Manzanita Elementary students contribute to wildlife camera project

Posted on:

October 3, 2017

The AZ Daily Star published a feature story about our partnership with Manzanita Elementary School on October 1, 2017. We are excited these students and teachers are getting recognition for their contribution to our Remote Wildlife Camera Monitoring Project and that this project is growing beyond our dreams. Lead teachers Jennifer DeBenedetti and Charlotte Ackerman have even developed a four-week curriculum based around the project called Critter Cams for Kids that provides a deeper foundation of knowledge about wildlife linkages and habitat fragmentation. 

To read the Daily Star article in its entirety, including photos of our youngest camera volunteers and Coalition Program & Outreach Associate Sarah Whelan, head here

You can also check out a wonderful YouTube video about the project and the curriculum that was developed to support the Critter Cams below.
