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.joint annual meeting, Oracle Road wildlife crossings, results, SR77 wildlife crossings, wildlife cameras, wildlife crossings, wildlife linkages, wildlife society
