The latest and greatest monitoring results from the Oracle Road wildlife crossings

Posted on:

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. 

March 2019 AGFD Monitoring Report on the Oracle Road wildlife crossings

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.

Pima County releases report on 2018 MSCP achievements

Posted on:

Last month, Pima County’s Office of Sustainability and Conservation released their latest annual report outlining the achievements of their Multi-Species Habitat Conservation Plan. According to an email from Environmental Planning Manager Julia Fonseca:

“Notable achievements during calendar year 2018 included:
•       The Section 10 permit covered impacts of 44 private development projects.
•       Forty-seven County Capital Improvement Projects were covered by the permit during calendar year 2018. 
•       A total of 974 acres of mitigation land was required to offset public and private impacts to habitat.  Over 4,000 acres is being allocated in the San Pedro and Cienega Creek valleys to compensate for current and future years of habitat loss.
•       The Regional Flood Control District (RFCD) estimates that the Section 10 permit saved them $200,000 in direct costs and $1.5 million indirectly due to avoided delays with one project.
•       The County developed a procedure allowing private developments to rely on Certificates of Coverage to streamline compliance with certain provisions of the County’s Native Plant Preservation Ordinance.
•       The U.S. Army Corps of Engineers and USFWS allowed a developer to rely on Certificates of Coverage to meet mitigation obligations for the Pima Pineapple Cactus under an existing Section 404 permit. This saved the developer an estimated $280,000.
•       The County RFCD reported a substantial increase in the number of riparian habitat reviews over last year.  Over 95% of applicants avoided impacting regulated riparian habitat, resulting in 2,196 instances of avoidance. 
•       Pima County staff, contractors, and volunteers removed or treated approximately 1,300 acres of buffelgrass on County preserve lands, and 90 tons of garbage from illegal dumpsites.

During the past year, Office of Sustainability and Conservation staff made 1,193 separate observations on Covered Species.  For me, one of the fun outcomes of staff’s efforts are their incidental observations, for instance this video of rattlesnake courtship at https://www.facebook.com/pimacountyarizona/videos/411068969458107   (Note, rattlesnakes are not Covered Species but careful observation will keep us all safe!)”

Pima County acquires new open space properties

Posted on:

February 25, 2019

Good news! According to Pima County Environmental Planning Manager Julia Fonseca, “In December 2018, the Pima County Board of Supervisors unanimously accepted a donation of 545 acres near the Ajo Scenic Loop in Western Pima County from a total of seven owners who wish to protect this natural desert over the long term. Pima County Regional Flood Control District also got full property rights to nearly 500 acres of the Big Wash near Rancho Vistoso Blvd. that was previously protected by a conservation easement.  The completion of the acquisition affords an opportunity to partner with the Regional Transportation Authority to address the gap in wildlife fencing between Rancho Vistoso Blvd and Oro Valley Hospital, supporting the Highway 77 Wildlife Crossing Structures.”

Pima County wrote in a memo about the 545-acre property near Ajo, AZ, “The properties are separated by a mountain ridge from the town and a large copper mining pit, and surrounded on the other three sides by mountains and federal land managed by the Bureau of Land Management. Alley Road, a dirt road maintained by Pima County, traverses the valley and is promoted by the Ajo Chamber as part of a 10-mile scenic loop…as well as the gateway to the Organ Pipe Cactus National Monument. The properties are also in close proximity to the Cabeza Prieta National Wildlife Refuge. The properties are within the Multiple Use and Special Species Management Areas of Pima County’s Conservation Lands System. The properties are largely undeveloped and contain an interesting mix of large saguaros and organ-pipe cactus. Desert bighorn sheep have been seen on the properties, and endangered Sonoran pronghorn are known to occur nearby.”

We are also very excited about the new protected open space in the Big Wash, a crucial piece of the larger wildlife linkage between the Santa Catalina and Tortolita Mountains. Wth your support, the Coalition will continue to work with Pima County and the Regional Transportation Authority to finish filling in wildlife fencing gaps – this will ensure the Oracle Road wildlife crossings are as effective as possible for the benefit of wildlife and people.

Sonoran Desert wildlife linkages featured in Desert Leaf magazine

Posted on:

CSDP Conservation Science Director Jessica Moreno published a new article in the most recent edition of the Desert Leaf magazine. Jessica’s article provides a fantastic summary of the history of wildlife linkages protection in Pima County’s Sonoran Desert, along with anecdotes and reflections on both black bears and Sonoran Desert tortoises and why they both need connected wildlife linkages to thrive.

Like black bears, tortoises have plant-based eating preferences. They also have few natural predators, can roam with compass-like precision and determination over hundreds of miles, and hibernate in the cold months. Tortoises get most of their water from the plants they eat, carrying it in canteen-like bladders. (Handling a tortoise can cause it to become anxious, pee, and thereby lose an entire summer’s water supply.) Roads and development are perilous hazards for them. But with thoughtful planning and community support, the threats posed by these hazards can be reduced or eliminated. In addition, safe crossings and open spaces benefit more than fuzzy bunnies, tortoises, and bears; they provide a beautiful, thriving, and resilient place for us to live.

The full article is available here.

Great work, Jessica! 

 

 

 

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.

Oracle Road Wildlife Bridge named for former Pima County Supervisor Ann Day

The Oracle Road wildlife bridge has a new name. On August 8, 2018, the Arizona State Board on Geographic and Historic Names approved the re-naming of the Sonoran Desert’s first wildlife bridge to the Ann Day Memorial Wildlife Bridge. Ann Day served as a Pima County Supervisor from 2000 to 2012 and was a champion of the Sonoran Desert Conservation Plan. Supervisor Day valued wildlife, protected open spaces, and building wildlife crossings throughout her tenure and service. She was tragically killed in a car accident inn May 2016 just days before the wildlife bridge was officially opened at a community celebration on May 10, 2016.

We are proud and gratified that Ann Day’s name will live on, both in the annals of Pima County history and as the official name for this important wildlife bridge that is keeping wildlife safe and reconnecting one of our critical wildlife linkages.

For more information, please read the Pima County press release and an article in the Arizona Daily Star.

Oro Valley’s Environmentally Sensitive Lands Ordinance produces results

Posted on:

Bayer Vella, the Oro Valley Town Planning Manager, recently wrote an informative and exciting article for TucsonLocalMedia.com. Titled “Oro Valley Town Talk: Environmental Conservation values, balance, and results,” this article outlines the positive impacts from Oro Valley’s Environmentally-Sensitive Lands Ordinance (ESLO). In the article, Mr. Vella states,

“How did the community determine the right balance of land conservation and permissible development in the Environmentally Sensitive Lands Ordinance? Beginning in 2008, and over the course of two years, there were two advisory committees including residents and technical experts, community forums, stakeholder meetings and public hearings used to draft the ordinance, with final adoption by town council in 2010. 

Building upon the work of Pima County’s Sonoran Desert Conservation Plan, the ESL employs a tiered system of environmental resource categories. Each category has its own open space requirements based on scientific analysis and specific general plan land use designations. An extensive biological study was conducted within the town limits resulting in a town-wide ESL map of these categories.

So, has ESL truly made a difference since 2010? From where I stand, the answer is a resounding “yes.”

ESL results in tangible design changes that conserve significant environmental areas while also providing realistic development options. Due to legal constraints, ESL predominately applies to re-zonings, and has been applied to 12 subdivisions situated on a total of 771 acres. A full 432 acres of that area were conserved as permanent and natural open space, equaling 56 percent of the total land area.

How does this compare to the town’s previous efforts to conserve open space? We studied the same 12 subdivisions to measure a “what if” scenario using the pre-ESL zoning requirements. The amount of total open space conserved would have been 175 acres instead of 432 acres. Clearly, ESL provides a regulatory structure that yields consistent results, which is a far cry from the lower amounts and less refined mapping of the past.”

The Coalition was an active and involved member of the advisory committees that Mr. Vella cites and advocated strongly for the strong conservation policies present in Oro Valley’s ESLO. We are excited and gratified to hear that the ESLO has had such a tangible and positive impact on the biologically-important lands in Oro Valley. 

Opposition to any proposed interstate in Avra Valley grows

Posted on:

The recently convened I-11 Joint Stakeholder Community Planning Group has released a press release and position statement opposing any proposed route for Interstate 11 in Avra Valley. The Coalition for Sonoran Desert Protection is a proud leader of this new community stakeholder group. The full press release is below:

Citizens Convened by Federal and State Highway Departments Strongly Oppose Highway in Avra Valley

Stakeholders find Common Ground in Downtown Route to Create a Sustainable City

Arizona Department of Transportation (ADOT) and the Federal Highway Administration (FHwA) recently convened representatives of several stakeholder organizations in a process to explore two alternative routes for the proposed Interstate 11 through Pima County. Stakeholders have developed a consensus position that re-designing I-10 and I-19 to accommodate co-location with I-11 could have a positive effect on downtown revitalization, while stating strong opposition to an “I-10 bypass” in Avra Valley. See letter here. “A freeway that borders Tucson Mountain Park, Tohono O’odham tribal lands, Saguaro National Park, and Ironwood Forest National Monument makes absolutely zero sense,” stated Carolyn Campbell, Executive Director of the Coalition for Sonoran Desert Protection. “The direct and cumulative effects of a freeway to these natural and cultural iconic places of the Sonoran Desert simply cannot be mitigated. This route should not be under consideration.”

Stakeholders believe that there are shortcomings associated with the federal review process that focuses on new highway construction.  However, “we believe that there could be a significant opportunity to address some of the historic negative consequences that resulted from the construction of I-10,” said Gene Einfrank, Menlo Park Neighborhood Association President. “The building of I-10 physically divided our community and diminished the quality of life of our downtown and other neighborhoods along the highway. Instead of simply adding new lanes to our existing highway, we should consider redesigning portions of it—either going underground or suspended—so that we can reconnect our city.” 

Moreover, stakeholders encourage a broader look at future transportation options, focusing on changes to the management of the existing highway to reduce congestion, including pricing, scheduling, and other programs; technologies that improve traffic flows; and enhancements to the rail system, including light rail and intermodal transportation.

The group recommends ADOT and FHwA refer to the I-11 Super Corridor study final document, which was submitted to ADOT in 2016, to draw inspiration on a comprehensive design. The Sustainable Cities Lab, hosted at the UA College of Architecture, Planning and Landscape Architecture, completed this transdisciplinary study on the I-11 corridor along with Arizona State University and University of Nevada, Las Vegas. UA’s study area focused on opportunities from Marana to south of downtown Tucson. Their outcomes incorporate the addition of light and heavy rail, walking, cycling, new technology for controlling traffic as well as incorporating alternative forms of energy production and transportation.
