The latest and greatest monitoring results from the Oracle Road wildlife crossings
In March 2019, the Arizona Game and Fish Department (AGFD) released their latest monitoring results from the Oracle Road wildlife crossings. AGFD typically releases monitoring results twice a year so we should have an updated monitoring report sometime this fall.
Two summary graphs from the report are highlighted below:
This graph shows the total mule deer crossings at both the Oracle Road underpass and bridge. Mule deer started using the bridge almost immediately after construction finished and have been used it steadily ever since (blue line). More recently, mule deer have become more acclimated to using the underpass, with increasing numbers successfully crossing all the way through the underpass since Winter 2018. It is well established that some wildlife species will use wildlife crossings right away with little acclimation while others may take years before they become acclimated and then will start using the crossing regularly.
This graph shows the total crossings by all wildlife species at both the Oracle Road underpass and bridge. Wildlife started using both crossings very soon after construction completed and have been using them steadily ever since. This new connectivity across Oracle Road increases the health of our local wildlife populations by allowing them to reach new home ranges and find mates (which then supports healthy genetic diversity) and also increases the safety of Oracle Road itself with a reduction in wildlife-vehicle collisions. Miles of wildlife fencing was also installed as part of this project – the fencing directs wildlife to the crossings themselves and was designed using the best available science to accommodate a wide range of wildlife species.

In March 2020, Pima County released its fourth annual report on its Multi-Species Habitat Conservation Plan (MSCP). The full report can be found on the Pima County website HERE. According to the Executive Summary, six Pima County capital improvement projects and 52 private development projects were “covered” by the MSCP in 2019. While these projects […]
Did you know that there are five wildlife underpasses that traverse Tangerine Road? These wildlife underpasses were finished in 2018 and the Arizona Game and Fish Department (AGFD) is now in the middle of a post-construction monitoring study of the crossings. In May 2020, AGFD released its latest monitoring progress report. We’re happy to report […]
Over the last year or so, we have expanded our work protecting Sonoran Desert wildlife linkages to the Rincon-Santa Rita-Whetstone Mountains wildlife linkage that is fragmented by Interstate 10 east of Tucson. 40 wildlife cameras are now collecting data in this wildlife linkage thanks to the amazing help of our volunteers and community partners! A […]
Arizona Game and Fish Department (AGFD) just released the latest and greatest monitoring data from the Oracle Road wildlife overpass and underpass. This represents FOUR FULL YEARS of monitoring these wildlife crossings since construction finished in March 2016. Some notable data and results include: 26 different species have been observed using the crossings, including 11 […]
