Diary of a Desert Identifier: Welcome to the Neighborhood or the Saga of the Clever Rodent

Posted on:

By Gay Russell

Being a Desert Identifier means going through large files of photos captured on a disc from the desert cameras.  The photos have usually been taken over several days, usually a week to 10 days.  You quickly begin to see the site as the same as any neighborhood, populated by certain characters (species) and some visitors.  The neighborhood usually has some mule deer from the local resident herd, a herd of  javelinas, the occasional coyote, a lone grey fox, roadrunners, skunks, the lone bobcat, and other interesting characters.

Recently I was fascinated with the saga of a plump, clever rodent and a local grey fox who was determined to capture the rodent!


The grey fox appeared, sniffing and digging at the area—he just knew the rodent was there!




Each time, the rodent would reappear after the fox left the scene, still safe and happy.    



After watching several unsuccessful hunting sessions by the fox, another neighborhood character joined the scene—-a ringtail!




There were 9 attempts by the grey fox to capture the elusive clever, plump rodent.  The ringtail attempted 8 different times to enjoy a meal that would include the rodent—to no avail. After over 1500 photos and a period of 10 days, the rodent was last seen at photo #1500—-still triumphant!

The saga continues . . . .

Updated COVID-19 Response Plan

Posted on:

Pima County is currently under a high rate of transmission as the Delta variant spreads (data here). The situation continues to evolve. Here is CSDP’s response plan to help slow the spread and to help keep our staff and volunteers safe:

  • All CSDP staff are fully vaccinated. We have in place a Pandemic Policy that provides paid leave for staff in the case of illness due to Covid-19, and contingency plans in the event that staff must be out for an extended period of time.
  • Staff are working remotely from home with short coordinated visits to the office as needed. Meetings and outreach, wherever possible, are being conducted virtually.
  • Our office in Suite 205 in the Historic Y building is currently closed to visitors except by appointment. The Historic Y’s current policy is that all tenants of and visitors to The Historic Y building must be fully vaccinated, or are required to wear a mask and maintain 6 ft distance from others, or remain outside.
  • Volunteers needing to receive or deliver camera equipment, SD cards, batteries or other supplies are coordinating hand-offs with Jessica. There is a drop off location at her house on the NW side of town, or she can leave/pick up supplies from your porch or at a mutual meeting location.
  • Desert Monitors should wear a mask when within 6ft of each other, and are encouraged to share their vaccination status with their fellow team members before meeting, as appropriate. New information shows that vaccinated individuals are still able to transmit Covid-19 to others and the CDC recommends everyone wear masks indoors. While hiking outdoors it is safer, we still recommend wearing a mask to reduce risk when you are closer than 6ft.
  • We adapted our Desert Identifier program so that volunteers can work remotely and on their own schedules. This has been highly successfully and will continue. 
  • Highway Cleanups remain suspended until this activity can be done safely for all participants and staff.
  • Mailing Parties are now “On Tour” with supplies being delivered and picked up from your porch.

CSDP’s position is to encourage everyone to get vaccinated, wear a mask, and to isolate when feeling sick or if exposed.

These are challenging times, but also times to celebrate and spread our joys, extend understanding and grace, and help everyone get through this together. Many of our adaptions to this unprecedented crisis have made our community closer, our teams stronger, our work more efficient, and our outcomes better, simply because we are uplifting and caring for each other.

Thank you for doing your part.

Public comment period now open on I-11 Tier 1 Final Environmental Impact Statement

Posted on:

On July 16, 2021, the Arizona Department of Transportation and Federal Highways Administration released the Tier 1 Final Environmental Impact Statement (FEIS). The FEIS now identifies TWO possible Preferred Alternatives, a West Option through Avra Valley AND an East Option that co-locates I-11 with I-19 and I-10 through the Tucson region.

Action #1: Please ACT TODAY and request an extension of the public comment deadline from 30 days to 120 days. 

You can read the comment letter we submitted with this request HERE. Feel free to copy the language in this letter and/or personalize with your own words. 

A summary of talking points from our letter requesting an extension of the public comment deadline include:

  • The 30-day comment period is insufficient for review of the documents and ensuring the public is aware of the opportunity to review and comment on the project.
  • Because the impacts of this project are intergenerational, we urge you to consider an extension to provide the public with a full and fair opportunity to participate in this process.
  • Many of the communities impacted by the Preferred Alternative Options within the Corridor Study area are minority and low-income populations who in many cases do not have access to the traditional means by which federal EIS processes are advertised and published. Both proposed alternatives will have disproportionate adverse effects on these populations and they will need adequate time to be notified via ground mail or other means.
  • The Western Alternative through Pima County is proposed through traditional Tohono O’odham lands where tribal members may have limited internet access.
  • The Draft EIS documents totaled close to 5000 pages of text, maps, and other figures – the length and breadth of this document warrants a longer public comment period to allow adequate review by the public.
  • A new Interstate freeway has not been built in this metropolitan area since 1961 – over two generations ago. Many of the issues will have long-lasting, significant impacts on our community and we need sufficient time to review the record, research issues and concerns, and provide a substantive response.

Action #2: Submit a comment stating your opposition to the West Preferred Alternative Option (can be done concurrently or separately from Action #1) 

The Tier 1 FEIS identifies TWO Preferred Alternative routes: 1) a West Option that runs through Avra Valley, and 2) an East Option that co-locates I-11 with I-19 and I-10 through the Tucson region. There is currently a 30-day public comment period for the FEIS, with public comments due on August 16, 2021 (see above for information on our efforts to extend this deadline to November 16, 2021). 

The overarching message we encourage in your comments is that ADOT/FHWA should ABANDON the West Preferred Alternative Option in Avra Valley. We are currently working on our comments and will be posting more details soon. Check back here for more information in the days ahead.

Field Notes: a nest of great horned owls

Posted on:

By Gay Russell

During the over twenty years I have lived in Sun City Oro Valley, we have had several sets of Great Horned Owls nest within our area.  In 2017, a pair made a nest in one of two large trees next to a golf cart path on the edge of the golf course and close to a major street.   Because of the location, I was able to document the progress of the owls. 

One of the parents was spotted outside the nest.  The first shots of the nest revealed fuzzy shapes of owlets; but not the exact number.   A few days later,  a single owlet was observed, peeking over the top of the nest.




As the owlets grew, they ventured out of the nest and it became clear that there were two owlets.  Shots of what are apparently some of the first ventures out of the nest were captured.  A parent was always on watch!  And, later, good close-ups of the owlets were taken.



It was a privilege to see the owls develop.  Even though the location was very close to a busy golf cart path and a major street in our development, the owls seemed to realize that they were safe within the area and would not be disturbed.  I felt fortunate to be able to document the process.


Thank you, Gay, for sharing this story and photos with all of us!

Amor from the Desert by Mely Bohlman

Posted on:

This piece was written on the stolen lands and waters of the Tohono O’odham and Yaqui/Yoeme.

Imagine yourself standing in the Sonoran Desert on a caliente summer day. Let’s paint the landscape by adding deep blue for the mountains that emerge in every cardinal direction and strokes of brown that create texture on the ground, the structural limbs of plants, and fill every crevice on this landscape.

You may feel the dusty, sturdy earth beneath your feet, the same sweeping surface that clouded the vision of indigenous ancestors’ eyes as they navigated through these desert lands. You may observe the occasional desert breeze that moves through your body, swaying nearby palo verde trees and breaking up the lull of the endless heat.

As you take a step, you might have a gentle creosote bush tapping you on your shoulder with its branch. It is full of waxy leaves and fuzzy globes from its flowers resembling planets in an out-of-focus telescope. Down in the wash, a catclaw acacia may have pulled on some fibers from your backpack, leaving a mark from its thorns that will remind you to watch out for it next time. You may see the sprinkles of desert confetti left behind from the blooming party that was hosted by the yellow petals of brittlebush, the red torches of the ocotillo, the pale-orange drapes of the globemallow, and the pink rays of starlight from the fairy duster. You make eye contact with a broad-billed hummingbird darting across- maybe spotting a flash of vibrant blue-green and blue-turquoise hues on its’ body and neck.

You may notice with only your ears the sounds of the desert spiny lizards scrambling through rocks and fallen mesquite tree branches. The cooing of the white-winged dove becomes your steady metronome, giving you the tempo, rhythm and heartbeat of the desert as the day unfolds. White-winged doves, you see, are warm and feathered fragments of saguaro flying in the desert- as the white-winged doves synchronize their migration with the reproductive cycle of the saguaro and maintain an asymmetrical ecological interaction.

The sweat beading up on the back of your neck feels cool, despite the powerful Sonoran Sun, beating down on your head. You may decide to seek refuge by stepping into the long and narrow shadow of an elder saguaro.

Support the 30×30 campaign

Posted on:

Have you heard of the 30×30 campaign? While this campaign has circulated for a while, it hit the national news recently when President Biden pledged in an Executive Order to preserve 30% of U.S. lands and waters by 2030. This ambitious goal is being called a “moonshot.” 

According to this recent article in The Guardian:

“One of the real exciting opportunities for [30 by 30] is that it’s really not a top-down mandate, where someone in DC is drawing the map and getting us towards 30%,” said Sierra Club lands, water and wildlife director Dan Ritzman. “The idea is really locally driven conservation efforts – these are bottom-up campaigns, where people familiar with the land and affected by its management will be deeply involved in its conservation.”

Even more information about the 30×30 campaign can be found in this article at

Want to take action in support of the 30×30 campaign?

First, contact Arizona Senators Mark Kelly and Kyrsten Sinema today and express your support for the 30×30 campaign, including the recently introduced Grand Canyon Protection Act. 

Senator Kelly’s DC Office: (202) 224-2235

Senator Sinema’s DC Office: (202) 224-4521

Here’s a sample phone script to help with your phone call:

“My name is _______ and I live in _______, Arizona. I want to thank Senator ______ for his/her support of efforts to protect Arizona’s wild lands and for introducing the Grand Canyon Protection Act in the Senate. I care about this issue because _________.

As you know, scientists are telling us that we need to protect 30% of nature by 2030 if we are going to stop the worst impacts of climate change. That’s why I’d also like to ask Senator _____ to publicly support the Biden Administration’s efforts to protect 30% of nature by 2030. We need Senator _______to lead efforts to protect more public lands and nature at home here in Arizona and nationally. Supporting the Grand Canyon Protection Act and 30×30 is a great start. Thank you!”

Second, RSVP for the 30×30 Spotlight Event on the evening of March 25th (exact time TBD). Join us to learn more about the science, challenges, and opportunities of protecting 30% of U.S. land and water by 2030 and learn more about opportunities to act in your state. At this event, there will be a speaker from National Geographic discussing the 30×30 campaign and the science behind it. RSVP today at

Closing the Gap: Fencing gaps near the SR77 wildlife crossings are coming to a close

Posted on:

by Jessica Moreno, Conservation Science Director

The last time I took a stroll down Big Wash, which runs along the west side of Oracle Road, the chill air pressed against my face mask but still managed to carry the smell of triangle leaf bursage and creosote. Gambel’s quail scurried away with their bustling chip-chip-chip alarm call. Dry for most of the year in that characteristic way our desert washes are, Big Wash has served as a connection for animals moving back and forth between the Cañada del Oro Wash and open space north of Rancho Vistoso. It has always been an important wildlife movement area, a key feature in a linkage connecting the Tortolita and Catalina mountains, and now, with two wildlife crossings in place and wildlife monitoring efforts nearing a decade milestone, we are learning more every day about the habits and movements of animals that often remain just out of sight.

Five year ago, when the wildlife bridge and underpass were built on SR77, the red ribbon was cut, the first critter crossed, and we celebrated. But the work wasn’t quite over. In addition to wildlife monitoring, Phase II of the project was to finish placing the last sections of wildlife funnel fencing. Wildlife fencing is an essential part of every successful wildlife crossing and is a vital component of this project to both effectively reduce wildlife-vehicle collisions and maintain a connected landscape for wildlife populations and gene flow. But a few jurisdictional issues and challenges to fencing placement threatened to hold up the whole project, so the decision was made to complete the difficult pieces after the crossing structures were done. Arizona Game and Fish Department’s roadkill surveys confirmed hotpots associated with these fencing gaps. It was a problem, but addressing it had to be done right.

One of these fencing gaps was on either side of the wildlife underpass, at the Rancho Vistoso neighborhood of Vista Mirabella. We placed wildlife cameras to monitor the gaps and reached out to the residents and the HOA to help solve the problem. The solution, made possible thanks to the leadership of the Town of Oro Valley and the wise suggestion of one of the residents, is an elegant one. And it may very well be the first of its kind for wildlife exclusion: wildlife fencing connected to the sound wall will close the gaps at the north and south ends of the neighborhood, while specially designed automatic gates will secure the neighborhood entrances.

This is a unique circumstance since these are public streets and the gates, which are designed like a gated community entrance, will open to any approaching vehicle. They are planned to remain open during high volume traffic hours and close at night. The Regional Transportation Authority is covering the cost out of remaining funds from the original crossing construction budget, including re-vegetation and projected maintenance, and Oro Valley is taking responsibility to maintain the gates into the future.

After four years of outreach and problem solving as a community, we hope that construction on this final piece of the puzzle will begin this summer. There are still details to figure out, but light is at the end of the tunnel and the end result, I think, is something everyone can be proud to have taken part in.

A big thanks to Coalition volunteers Pat and Henry Miller for their help in monitoring the fencing gaps and their overall involvement in this project! And thank you to the Regional Transportation Authority, Pima County, the Town of Oro Valley, and the Arizona Game and Fish Department for your shared persistence in this project. 

More information about this project can be found in a Power Point presentation recently created by the RTA and the Town of Oro Valley.

Remembering Bob Cratty

Posted on:

by Terry Minks

Bob was a dear friend to all his acquaintances in Sun City, Oro Valley and to my wife and me ever since we came to live in Arizona 18 years ago. Bob delighted in introducing newcomers to his favorite places throughout Arizona. He was a history buff and was the first person to give us a tour of many historical sites in the state. As a native Arizonan growing up in Ajo, he took us on a fascinating tour of his home town, telling stories of John Greenway’s influence and adding first-hand historical tidbits all along the way. He also led many historical hikes for our Sun City Hiking Club, founded an astronomy program for 5th graders in Catalina that gave each student a telescope, and befriended countless others with his generous spirit. During our many bike rides throughout the Tucson area, always with a food destination, he would customarily leave an extra-generous tip and encourage us to do likewise.

In about 2006 he was instrumental in getting our SCOV board to buy several wildlife cameras to photograph wildlife in our neighborhood. By 2008 he became aware of the UofA Wild Cat study led by Lisa Haynes and arranged for several of us to be trained in wildlife tracking and camera monitoring with Jessica Moreno. We started with Sky Island Alliance and continued later with the CSDP until the present.

He was full of original ideas which he implemented in service to others. He never uttered a harsh word even against those with whom he disagreed and never argued, only presented his own views which were always based on deep reading and thinking on his part. He had a quick wit and was a master storyteller. Many of us recall his deeply researched stories of ants, which he often shared on our hikes and bike rides together.

Bob was certainly a gift to our entire community and will be deeply missed by all of us.

Bob passed away on December 20, 2020. The new CRATTY wildlife camera is named in his memory.
