State Route 77 (SR 77) at the northern edge of metropolitan Tucson, Arizona, is a six-lane highway that divides the regionally important Santa Catalina-Tortolita Mountains Wildlife Linkage. This linkage, threatened by a growing network of new roads and development, encompasses US Forest Service lands and Catalina State Park on the east and county parkland on the west, and threads through the urban and suburban interface of the Town of Oro Valley. In 2012, the Coalition for Sonoran Desert Protection (CSDP) began a community science wildlife monitoring effort using camera traps to track the presence and movement of wildlife in the linkage, in conjunction with planning and advocacy efforts to fund necessary wildlife crossing structures. This led to the first wildlife overpass in the Sonoran Desert and an additional wildlife underpass, both constructed in March 2016. Now nearly 10 years since its inception and five years post-construction, this project has documented over 62 species across over 50 sites, including desert tortoise, bighorn sheep, mule deer, whitetail deer, javelina, mountain lion, badger, and white-nose coati. Cumulative detections show increasing mule deer activity west of the highway after the wildlife crossing structures were completed. This wildlife activity data within the study area has complemented the crossing structure wildlife passage rate, roadkill hotspot, and targeted tortoise and mule deer movement studies conducted by the Arizona Game and Fish Department. Together these data provide a holistic understanding of the success of the project while informing mitigation strategies and lessons learned to improve highway safety and regional wildlife connectivity. Several emerging challenges, including closing remaining wildlife-fencing gaps with local neighborhood buy-in and addressing the development of an encroaching multi-use trail, were helped and informed by the study and by the engagement of the local volunteers involved. This included years of meetings and consultation with neighborhoods adjacent to the wildlife underpass and the design of custom motion-activated swing gates at neighborhood entrances to fill wildlife fencing gaps that remained after construction concluded on the crossing structures. Our camera trap photos and wildlife activity data have been instrumental for community outreach throughout the process. We discuss the study results in context of these larger challenges and the successful and innovative solutions that were developed as a model for future projects.
