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 a clear, crisp day on March 6, and the freshly brewed coffee was almost as invigorating as the arrival of several school bus-loads of fourth graders and parents from Manzanita Elementary. Over 100 curious minds boiled out into the lower parking lot of the Santa Catalina Catholic Church on Oracle Road just south of the wildlife bridge. “Critter Cam Day” had arrived.

Coalition volunteers were already stationed around the seven activity tents laid out around the parking lot, as kids split into organized groups led by teachers Charlotte Ackerman and Jennifer DeBenedetti of the Manzanita Robotics Club. These students have been sorting and studying the Coalition’s wildlife camera photos as part of a new 4-week curriculum developed by Ackerman and DeBenedetti in partnership with CSDP. Today, they would have a field day.

It may not be surprising that the activities held their rapt attention and their colorful field guides, made especially for this day, were quick to be filled. Finely timed rotating activities included a spotting scope station to view the wildlife bridge and mapping points of interest. Mark Hart with Arizona Game and Fish Department taught wildlife tracks and track tracing skills. Wildlife rehabilitator and CSDP volunteer Kathie Schroeder and her outreach hawk Sueño shared the adaptations of Harris’s hawks and other birds of prey. Mr. Packrat brought a guest too – and shared the desert adaptions of native packrats. Stations also included games and activities to teach camouflage techniques and the importance of pheromones and scents. And of course, the day would not be complete without a guided nature walk to check a wildlife camera!

Throughout the morning, students and parents were absorbing the skills and knowledge of naturalists and scientists and giving back a thirst for more. As we met around the leftover coffee and homemade granola bars after the day was done, teachers, volunteers, and guest contributors all agreed that very few improvements could be made to this positive and inspiring day. The success of this event is something we hope to repeat, and expand next year. Eventually, we hope this will be a curriculum that can be packaged and adopted by other TUSD schools. Not unlike the critters now crossing new bridges, these students are poised to bridge the divide between knowing – and doing.

Emerging issues with the Oracle Road wildlife crossings create opportunities for stronger community connections.

Once a wildlife crossing is built, the project still isn’t done. CSDP has remained actively involved with the wildlife bridge and underpass project on Oracle Road since its completion, helping to install educational signage, planning re-vegetation and erosion control, engaging on emerging issues like motorized use and other encroachments, and, of course, monitoring changes in local wildlife. For little over a year, we have also been focusing on building a stronger connection with the local Rancho Vistoso HOA and with the roughly 60 homeowners living near the crossings. Javelina, coyotes, desert tortoise, and a myriad of smaller wildlife have been slipping through gaps in the wildlife-funnel fencing, resulting in a two-mile plume of roadkill extending south of the underpass on Oracle Road. These open gaps are the cul-de-sacs and drainage areas within the underpass’s adjacent HOA neighborhood, where animals can access the street and bypass the wildlife underpass. While the idea of wildlife fencing in the neighborhood is understandably undesirable for most homeowners, we have been slowly coming together to find solutions and a compromise that works for all.

 

With some exceptions (there are always a few), wildlife are excellent neighbors. Quiet, shy except around the bird feeder, we mostly don’t even see them unless we make an effort to look. Yet they provide us with spontaneous joy when do catch a glimpse. The therapeutic hum of tiny wings at the feeder during a spring rain and the bright-eyed peaceful stare of a deer in the chill morning can make time stand still. Wildlife watching from our yards and community areas is part of why many of us choose to live here. According to a 2011 report conducted by the Tucson Audubon Society, in Pima County alone wildlife watching supported more than 2,700 jobs, and directly produced $19.8 million in local and state tax revenue from over $179 million in wildlife watching related spending. In one year! It’s nice to know that the pollinator plants and binoculars I bought contribute to a thriving economy, but I’m just as happy to see the tracks of the local bobcat when I go for stroll in the evening and to add another hummingbird to my yard list.

 

It is also good to know that our wildlife crossings on Oracle Road are working wonderfully, with mule deer, javelina, bobcats, coyotes, and more using them regularly. That investment has truly paid for itself, by supporting local wildlife watching opportunities and by reducing the taxpayer and personal costs of wildlife-vehicle collisions. There have been over 2,900 animal crossings on the bridge and underpass recorded to date, and – where the wildlife funnel-fencing is complete – roadkill is down to near zero. After the surprise of tortoises and bighorn sheep last season, one of the local homeowners photographed a beautiful badger (local nighttime rodent control, at your service) near their home west of the wildlife underpass in early February. We now have evidence of badgers on both sides of the wildlife crossings, and neighbors are sharing their sightings and their stories.

Here where people and nature encroach upon each other, finding balance can be challenging. The peaceful gaze of a deer tells me that the return in our investment, and the reward, is well worth some compromise. As wildlife adapt to their changing landscape, we can continue to enjoy their presence and strive to be a community of good neighbors in return. By bringing the community together as part of the process, we all share in that success.

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 wonder of bighorns and tortoises

Posted on:

A Sonoran Desert tortoise, affectionately nicknamed “Calypso” by the family that found him, gets ready to be released back into the wild with a tracking device affixed by the Arizona Game and Fish Department.

by Jessica Moreno

Calypso is a healthy desert tortoise of about 25-30 years and a tortoise on a mission. He was named by a caring, bright 7-year old, whose family found him on their front doorstep no less than three times – after several kindly reminders to return to Big Wash and to stay on his side of the street. When they called us, I was eager to meet them. Arizona Game and Fish biologists joined me and placed a tracker on his shell using special putty, offered him a drink, and we returned him with ceremony once again to Big Wash, carrying him low as we crossed back over the street. Calypso was trying doggedly to travel east, but instead of using the very accessible wildlife underpass, he was taking the open high road: climbing up a rocky embankment, crossing the busy neighborhood street, and wandering just yards from the highway. (His tracker confirms he is now finally snuggled in for hibernation over winter, southwest of the wildlife bridge.)

Calypso may live to reach the ripe age of 80. But his story almost ended differently, and there are still animals getting killed on Oracle Road by moving through openings in nearby neighborhood streets, where either cattle guards couldn’t be installed at the highway entrance or the sound wall ends. We have identified the last remaining areas like this where animals like Calypso are accessing the street – and the highway – near the wildlife underpass in the Vista Mirabella and Vistoso Vistas neighborhoods. Arizona Game and Fish Department’s roadkill surveys confirm a growing hotspot of animals being killed on the highway south of the underpass crossing, where these gaps in the wildlife funnel-fence begin. The Regional Transportation Authority, the Coalition for Sonoran Desert Protection, and your Rancho Vistoso HOA have joined together with neighbors to solve this problem. We’ve been communicating closely with residents living next to these openings to find the best fencing solutions.

Thanks to residents’ help and feedback, the first of these gaps have been closed to wildlife at the end of N. Big Wash Overlook Place. A pedestrian gate was included for trail access to Big Wash. The wildlife fence has been a critical part of the effectiveness of the wildlife crossings, and we look forward to working with residents to close the remaining few gaps so wildlife like Calypso can continue to travel between Big Wash and Catalina State Park without risk of traffic accidents or casualty.

The promise of that remains. Recently, a young desert bighorn ram trotted down a small desert wash east of Oracle Road – the wildlife underpass directly before him, and the Catalina mountains behind him. This rare and memorable wildlife camera photo out of hundreds collected that morning caused us all to cheer! The potential is there for the Big Wash Wildlife Corridor to become a path for Tortolita-bound bighorns.

The importance of this effort lies still in my heart. It comes with the wonder, excitement, and hope that a bighorn and a tortoise bring. For all of us desert dwellers, what better gift is there than that?

The new Big Wash Multi-Use Trail has been in Pima County’s planning books for decades. However, with wildlife funnel-fencing guiding animals into the area near the wildlife crossings, and surrounding development constraining open space, Big Wash has gone from an important wildlife movement area to a wilderness-style traffic jam of animals moving and living in this natural corridor. The Coalition successfully worked with Pima County to move the multi-use trail further west, away from the crossing structures. And, by asking people to stay on the trail, we can give people the chance to enjoy the desert without disturbing the larger area and the needs of the critters that rely more than ever on Big Wash. We are also working with Pima County after some erosion-control work in Big Wash resulted in re-vegetation needs near the wildlife underpass. Wildlife are moving around with a bit more frequency before the cold of winter sets in, and we’ve seen quite a few other surprises.

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

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.

Our Remote Wildlife Camera Monitoring Program is continuing to grow! This past year, we recruited some new help from our friends with the Manzanita Elementary Robotics Club. Interested in exploring the use of technology for use in pulling data from the field, data management, species identification, and how this data can be used for public planning purposes, the Robotics Club asked to aid in our work while learning the ins and outs themselves. Led by two enthusiastic teachers, Charlotte Ackerman and Jennifer DeBenedetti, the Manzanita Robotics Club funded and helped place two cameras in our Oro Valley study. Continuing forward as we pull data from these cameras, students of the club will work to help sort, identify, and analyze the data. We’re excited to engage young minds about the importance of open spaces and understanding the ecosystems that surround us. Looking ahead, we are hoping to continue this partnership by expanding the number of camera monitored by the Robotics Club and assisting the participating teachers in the development of their new curriculum around this project. 

Thank you to Charlotte Ackerman and Jennifer DeBenedetti for spearheading this project!
