April 30 through May 3, 2021 the Arizona Master Naturalists participated in the City Nature Challenge where community members documented plant and animal species using the app iNaturalist. The City Nature Challenge is a global project and 1,270,767 observations were made this year. Over 45,300 species were identified and more than 2,100 rare, endangered, and threatened species were observed. Over 52,777 observers participated in the event while enjoying the outdoors as volunteer community scientists.
Here in Tucson about 200 people participated in the event! Over 2,500 observations were made and included over 640 species. Our most common observations included:
Our top Observers included usernames:
The locations in which observations were made could reflect where accessible natural spaces exist in our city. Tucson is located at the base of surrounding mountains and is famous for being surrounded by parks and trail systems. By looking at the City Nature Challenge’s interactive map we can see that participants were able to make observations both within our parks and our urban environment!
Check out what observations were made by visiting the Tucson City Nature Challenge Website.
Thank you to everyone who participated and enjoyed the outdoors while celebrating community science month, and special thanks to our community members that helped coordinate this event!
My youngest daughter (Avery Lane) just completed the 800 mile Arizona Scenic Trail (AZT). I provided logistical support and accompanied her on a few of the segments. It took her (50) days to complete the (43) passages from the Mexican border, in the Huachuca Mountains, to the Utah border on the the Kaibab Plateau.
The first couple of miles are a bit odd. You can park at Montezuma Pass in the Coronado National Monument but then must hike south for ~2 miles to the obelisk marker at the actual border. When Avery and I did this section, the trail to the border was still ‘technically’ closed due to border wall construction…..!
As you turn back and head north you pass Coronado Peak. This is where Dale Shewalter, a Flagstaff public school teacher, envisioned the idea of linking trails on private and public land to span the entire State. The last passage of the AZT was completed in 2012. There is a Golden Spike on Passage 16 just north of the Gila river to commemorate this accomplishment.
The remainder of this post will attempt to show some of the amazing biogeography of our State. Hopefully it will encourage you to consider exploring some of the passages. Most people who enjoy the AZT are not ‘through-hikers’ but rather divide it up over time. Please feel free to contact me or Avery if you have any questions. Contact info below or through Pima County Chapter of the Arizona Master Naturalists.
Pima County Master Naturalists Penny M and Joshua R recently volunteered with Wild At Heart’s Burrowing Owl Project. Wild At Heart (WAH) is a nonprofit conservation organization that rescues, rehabilitates, and releases birds of prey. Their Burrowing Owl Project creates artificial burrows for owls and relocates owls from upcoming development sites to safe spaces throughout the region.
Wild At Heart was created in 1993 and was the first program to create artificial underground owl burrows. Bob and his wife “Sam” Fox, founders of WAH, identified a need to build artificial owl burrows in Arizona and began this relocation program. In 2001, Greg Clark became Wild At Heart’s Burrowing Owl Habitat Coordinator who expanded Wild At Heart’s rescue and relocation procedures.
“We are currently in one of the high intake periods where owls are being trapped to remove them from new development areas at a rate of 400-500 per year,” shares Clark. “Last year I relocated 400 Burrowing Owls but we still have owls coming in and we are in a foot race to get more habitat installed so owls can be relocated as fast as possible.”
Volunteers are part of this solution! Wild At Heart burrowing owl events are open to the public. Thousands of volunteers have helped build over 6,000 artificial burrows — providing homes for 2,500+ owls.
Western burrowing owls (Athene cunicularia hypugaea) are charming little owls who get their name from nesting in underground burrows. They incubate and raise their chicks within burrows that they borrow from other species like prairie dogs and ground squirrels. Burrowing owls are vulnerable to predation from a variety of other wildlife and are especially vulnerable to construction and land development projects. The western burrowing owl is the only fossorial owl species in the Americas, and is endangered in Canada, threatened in Mexico, and a species of special concern in the United States.
“Land next to active irrigated farmland is preferred by the owls,” says Clark. “Marana is one of those areas. Most of the owls come from Maricopa and Pinal Counties. Specifically, Buckeye is in the bullseye right now. Perhaps your chapter can help us find more land for relocation.”
If you are interested in helping The Burrowing Owl Project or volunteering with Wild At Heart you can donate, head to their website, follow them on FaceBook, or contact them at info@WildAtHeartOwls.org.

Cristate Saguaros, also known as fasciation, is a relatively rare condition in which the growing tip, or apical meristem, of a vascular plant exhibits abnormal growth. The apical meristem is normally concentrated around a single point which allows for approximately cylindrical growth. Instead, the tissue becomes elongated perpendicular to the intended direction of growth. This results in a flattened, ribbon like crest or elaborately contorted tissue.
Cristate are known to occur in over 100 species of plants including many cacti, aloe,acer, euphorbia, digitalis and even cannabis. It is not known what causes cristate but there are many hypotheses: A. genetic mutation B. micro-organisms C. hormonal activity D. damage due to freezing or lightning
A cristate saguaro will still produce viable flowers, fruit and possibly arms emanating from the crest. The incidence of this condition is uncertain but is believed to occur in 1:200,000 to 1:250,000.
In 2005, two members of the Tucson Cactus and Succulent Society (TCSS), Bob Cardell and Pat Hamness, created the Crested Saguaro Society (crestedsaguarosociety.org) whose mission is to find and document all crested saguaros in the Sonoran Desert. At its inception, there were believed to be approximately 200 crested saguaros in existence. To date they have documented over 2000.

I came across a brochure in the Sabino Canyon Gift shop titled, “Map of Sky Island Scenic Byway”. I know a lot has changed in the 16 years I’ve been away from Tucson, but when did we get Sky Islands? And more importantly, what are they?
Sky islands are a type of continental or inland terrain made up of a sequence of alternating valleys and mountain ranges. Isolated mountains are separated from one another by physical distance resulting in a mountain “island” surrounded by “oceans” of desert or grassland. The slopes and summit have a dramatically different ecosystem from the base and distinctly different biospheres occur all the way up the mountain with various types of life existing at each level. Sky islands have a stack of biotic communities that allow seasonal vertical migration between highland and lowland habitats but the valleys between them act as a barrier preventing species from crossing from one mountain range to another. There are about twenty groups of sky islands on the planet, all continents with the exception of Australia harbor sky island complexes.
One of the most renowned chains of sky islands can be found in an exspansive cluster in Arizona, New Mexico and northern Mexico, known collectively as the “Sky Islands”, “Madrean Sky Islands” or “Madrean Archipelago”. The descriptions of this area read like a giant cosmic recipe for biodiversity: Begin by connecting the massive continental back- bones of the Rocky Mountains with the Sierra Madre Occidental. Blend in temperate, sub-tropical, and tropical latitudes. Add a dash of elevation, sometimes up to a 6,000 ft. gradient from valley to mountain peak. Flank these peaks with the Chihuahuan and Sonoran deserts in an east-west overlap. Finally, mix it all together with a bi-seasonal rainfall pattern, with frontal winter precipitation and convective summer thunder storms arriving from different regions of the Pacific Ocean and providing life-sustaining rainfall. This unique and intricate blend of topography, location, and weather create an explosion of life found nowhere else on the planet.
This concept originated in 1943 when Natt N. Dodge referred to the Chiricahua Mountains as “a mountain island in a desert sea” in an Arizona Highways article. Nature writer Weldon Heald, who lived in the Chiricahua Mountains of southeastern Arizona, popularized the term. In his 1967 book, Sky Island, he demonstrated the concept by describing a drive from the town of Rodeo, New Mexico, in the western Chihuahuan desert, to a peak in the Chiricahua Mountains, 56 kilometers (35 miles) away and 1,700 meters (5,600 feet) higher in elevation. Ascending from the hot, arid desert, to grasslands, then to oak- pine woodland, pine forest, and finally to spruce-fir-aspen forest.
This region spans four states and two countries, covering a patchwork of protected and unprotected public and private lands. The majority of the Sky Island mountain ranges in the U.S. are part of the Coronado National Forest. In Mexico, the mountains and low desert valleys are a mixture of private ranches, ejitidos (communal farm plots) and Reserva Forestal National. The Sky Island region has approximately 65 isolated mountain ranges covering roughly 70,000 square miles overall. The U.S. Mexico borders splits this region nearly in half with 20,000 square miles in the United States.
Valley floors within the Sky Island region vary between 2,500 and 4,500 feet while the isolated mountain peaks rise 6,000 to 11,000 feet with temperatures dropping about 4 degrees Fahrenheit every 1000 feet.
Eight distinct biotic communities are recognized on the highest Sky Islands of Arizona: Desert Scrub, Desert Grassland, Oak-Grassland, Oak-Woodland, Chaparral, Pine-Oak Woodland, Pine Forest and Mixed Conifer Forest. These 8 communities encompass five of the world’s great biomes: Desert, Grassland, Mediterranean Woodland and Shrub land, Temperate Broad-leaf Forest, and Coniferous Forest. Not every Sky Island is high enough to sustain them all; many are lacking pine and mixed coniferous forest.
Moist air moves up from the Gulf of California in the summer and the North Pacific in the winter. When these air masses are forced up and over the mountains, water vapor con-denses, forming clouds and rain. The mountains pull the water from the sky and bring it back to the landscape where it creates washes that recharge the aquifers and supply riparian areas, bringing life to plants, animals and people as it moves to the valleys below. One of the unique aspects of this region is the mix of floristic affinities, the trees and plants of higher elevations are more characteristic of northern latitudes while the flora of the lower elevation has ties to the desert and mountains further south. It is the only group of sky islands on the planet straddling two major floristic and two faunal realms as well as three major climatic zones: Tropical, Subtropical, and Temperate.
The Madrean Sky Islands contain some of the most rugged and remote lands in the southwest and feature some of the highest levels of biodiversity in the world. The Sonoran portion of the Sky Islands is not as well known biologically speaking but the Arizona portion is amazingly diverse hosting species that draw from all directions, elevations and latitudes. Although some species show little genetic variation between mountain ranges, other species have evolved on these mountain islands. Like a bunch of separated terrariums, they serve as natural laboratories for the study of evolution because conditions differ from island to island.
More than half the bird species in North America are found here as well as, 29 bat species, over 3,500 species of plant, 150,000 invertebrate species and 104 species of mammals, the highest concentration of mammals in the United States.
Plants and animals of every shape, size, and specialty reside here. From familiar favorites like the giant Saguaro Cactus towering 60 feet above the earth “holding it’s breath” all day to conserve water, to the many species of tiny Talus Snail, found deep intalus crevices and leaf litter, only surfacing after it rains. Mexican Gray Wolf, Thick Billed Parrot, New Mexican Ridge Nosed Rattlesnake and Apache Trout are a few of the endangered species that live here and in recent years the Jaguar and Ocelot have returned. There are many other rare creatures found here, with names that capture our imagination like Tropical Soldier Fly, Santa Catalina Geometer Moth, Sonoran Tiger Salamander, and Elegant Trogon just to name a few. Several new species discoveries have been made such as the colorful Fire -Tailed Ground Snake, the Black Tailed Ringtail Dragonfly and a yet unnamed species of Bog Orchid. Bee, reptile, and ant diversity is unparalleled here, speaking volumes about the sub-tropical influences withinthe region.
The bi-national Madrean Archipelago or Sky Island region of the southwestern UnitedStates and northwestern Mexico is recognized for its unique biological diversity, naturalbeauty, and cultural heritage.
Today the most significant threats to the Sky Island Region are climate change, over-grazing, fire suppression, loss of predators, energy development, mining, and borderissues. Groups such as The Sky Island Alliance are working on both sides of the border to protect and restore the biodiversity and natural heritage of the Sky Islands. They work with volunteers, scientists, landowners, public officials, government agencies and over a hundred partner organizations to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity. Their Madrean Archipelago Biodiversity Assessment (MABA) project is a groundbreaking effort to extend knowledge of animals and plants in the Sky Islands of Arizona and New Mexico southward into Sonora and Chihuahua, Mexico. The biodiversity in the Madrean Archipelago is recognized globally, but information about species distributions is critical to understanding and protecting biodiversity.
The Biodiversity and Management of the Madrean Archipelago Conference (known as the “Madrean Conference” or “MADCON”) is a regional event for sharing science and building collaboration and is part of a series that still shapes our understanding of the region through presentations given in 1994, 2004 and 2012. The conference is a dynamic opportunity for researchers, managers, and conservation practitioners to learn the latest science and translate it intopractical management approaches.
There is still so much to discover and learn about this region and with the very real threat of climate change there is no time to waste. Just as our magnificent Sky Islands connects mountain ranges, deserts, states, and even countries, successful conservation also requires connections. Not just across the physical and political landscape but most importantly conservation requires connection between people and the place they live. It’s good to know that there are so many working to foster these connections in order to restore and preserve the truly unique biodiversity of this region that is our home.

In March of 2020, as the potential scope of the pandemic became clear, opportunities to volunteer changed dramatically as organizations shut down suddenly for the safety of the public. Since then, as the virus numbers dropped and then rose again, government, organizations, and schools have struggled to understand the “new normal,” and to find new ways to continue their missions while safeguarding public safety. Master naturalists have also faced personal choices about when and if they can volunteer, but the guiding principle must be safety first. Our organization has reduced the requirements for volunteer hours and has been flexible and creative about offering service hours for activities that support our core mission of education, stewardship, citizen science and leadership, but that can be done independently or in small groups with special safety procedures.
Some of our partner and associated organizations have cancelled or altered programs and activities. For example, the National Park Service Desert Research Lab and Learning Center has been closed to visitors and has suspended their citizen science opportunities and the Udall Foundation’s Parks in Focus has not had “in person” volunteer activities with student groups. The Watershed Management Group encouraged individuals to “steward in place” and clean up trash in their neighborhoods and local watersheds rather than participate in large, organized clean-ups.
The Sky Island Alliance launched their FotoFauna program in late 2020, as a way to build and connect a large network of wildlife cameras across the Sky Island region. In addition to their own wildlife cameras, and those of other conservation organizations, they enlisted the support of individuals who have backyard wildlife cameras to record wildlife and submit monthly checklists. You can read more about it here: https://skyislandalliance.org/our-work/wildlife-program/sky-island-fotofauna/. SIA also needs virtual help with species IDusing iNaturalist and Zooniverse with their ongoing Border Wildlife Study. Other opportunities for volunteering in your own backyard include bird counts, phenology projects and other dispersed citizen science activities.
Some opportunities for in-person fieldwork with special COVID protocols still exist. Buenos Aries National Wildlife Refuge recently held their annual week-long Pima Pineapple Cactus Survey. Their safe practices included; outdoor, socially distanced orientation sessions, required masks, special consent and releases forms, participants drove to the study area in their own vehicles instead of car-pooling, extra water or Gatorade was available in individual bottles rather than refilling from a cooler, individuals were socially distanced while walking transects, and they did not eat lunch together.

Arizona Master Naturalist – 2018 Cohort
I froze in my tracks. For any experienced naturalist hiking in the Sonoran Desert, the sound of a rattlesnake elicits that reaction. I carefully surveyed my surroundings…nothing…nothing… nothing…ah…there it was! But it was not the western diamondback I had expected to see on the trail in Arizona’s Tortolita Mountains; instead I was looking at a roadrunner. The loud clacking of its beak – reminiscent of the staccato clatter of castanets – was clearly a warning; perhaps I was was too near its nest. Members of the cuckoo family, both male and female roadrunners produce this clacking sound, as well as a “bark” sounding more like the cluck of a quail. The male roadrunner also makes a dovelike coo to mark its territory and call for a mate. When the roadrunner stopped clacking, I gave the agitated bird wide berth and continued hiking.
This trail northwest of Tucson is centrally located in the Greater Roadrunner’s range, spanning the American Southwest and northern Mexico. A smaller close cousin, the Lesser Roadrunner or Geococcyx velox, occupies a much smaller range in the southwest regions of Mexico and parts of Central America. It can be found at elevations from sea level to over 6,000 feet and in biomes from grasslands, to foothill woodlands, to chaparral; but it is most readily recognized as a desert dweller, and is undeniably the avian icon of the Mojave, Sonoran and Chihuahuan Deserts. The common element the roadrunner requires in any habitat is large or dense cacti, shrubs or trees. These plants provide shade and lower temperatures during the hotter months, insulation for warmth during the cooler months, protection from predators and nesting sites.
From the tip of its curved beak to the tip of its long tail, the adult roadrunner is nearly 2 feet in length and weighs about 12 ounces. Both sexes are similar in appearance – the male just slightly larger – with a heavily-streaked plumage of white, brown and black, a crest that can be raised or lowered at will, and a post-orbital bare streak behind its eye colored white, slate blue and orange. Its long legs with the cuckoo’s zygodactyl toes (two toes pointing forward and two toes backward) give this bird its distinctive X-shaped tracks, and enable it to reach speeds of over 15 MPH. True to its name, the roadrunner prefers to run, darting and dashing after prey, and flying only a few feet high to gain perch or a few yards to quickly outdistance a predator and seek cover.
The roadrunner is an omnivore, it’s diet consisting of 90% prey – mostly small lizards and snakes. It also consumes small rodents or birds, scorpions and insects. The other 10% of its diet is the fruit and seeds of cacti. This diurnal predator it is most legendary for being a rattlesnake killer. Able to digest rattlers up to 18” long, the roadrunner first approaches the snake cautiously, sizes it up, then attacks. It will use its beak or feet to poke the snake, actually provoking it to strike. If needed, the roadrunner evades the strike by deflecting it with its wings or quickly hopping out of range. But more often it uses its agility, speed and powerful beak to grab the snake’s head mid strike. Once caught, it uses a whiplike motion to beat the snake repeatedly on the ground, causing multiple spinal fractures and death, and making the meal more malleable for digestion.
This male roadrunner holds a lizard in his beak, which he will offer to her after mating.
Like many animals, this predator is also a prey for other carnivores. Although a fortunate coyote or bobcat may snag a roadrunner on occasion, roadrunners seldom fall prey to these mammals. The roadrunners’ main threat are raptors, particularly Cooper’s hawks and prairie falcons.
The raptor must catch the roadrunner off-guard however, as numerous anecdotes are told of wary and wily roadrunners taunting hawks, always evading capture, and finally tiring their foe to the point that they actually chase it away from their nests.
If roadrunners avoid predation, they may live to be six or seven years old, and produce several offspring during their life. The male roadrunner approaches a female in the spring of the year with a twig in his mouth, a not-so-subtle invitation to building a nest together. Before she approves of him as a lifelong mate, she will put him through many courtship rituals. All of these are to test his prowess as both a provider and protector. His final approach is with a vertebrate offering, such as a small lizard or snake. If she assents he will mount her – the tasty treat still hanging from his beak – which he will reward her with once copulation is complete.
A second breeding season may occur in fall, depending on abundant summer rains and resulting ample prey. In wet years two, three or even four clutches of eggs may be produced. In dry years, no breeding may take place. Each clutch produces three to six eggs which are laid in a nest typically located low in the thicket of a paloverde or mesquite trees or cholla cactus. Only half of the hatchlings will survive to maturity; the remainder fall victim to starvation or predation.
Both sexes take turns incubating the nest, though he is responsible for the night shift, as she must conserve her energy. Like all roadrunners not nesting, her body temperature drops dramatically at night, from 103℉ to 93℉. As she sleeps her metabolism will slow and her body cools, reducing her caloric need some 40% over her mate. In the morning she will reverse the process, turning her back to the sun, lowering her tail and spreading her wings. She erects the feathers on her back, exposing a patch of black skin that heats her body through solar radiation. Her high daytime body temperature is an adaptation to better cope with the ambient desert heat.
A female roadrunner exposes the black “solar panel” on her back used to warm her body.
With its amazing adaptations, amusing antics and abilities as a hunter, the roadrunner has earned the respect of all cultures, both ancient and modern. The Chemehuevi tribe of the Mojave Desert derive their name from this bird; the story is told when tribal leaders first saw the Chemehuevi Valley full of mesquite beans, they raced down to it with their “nose in the air like a roadrunner”. Cowboys told tales how the roadrunner would seek out sleeping rattlers, then build a corral of cholla cactus joints around them to entrap the hapless reptiles. Warner Brothers Studios Roadrunner cartoon has remained popular since its 1949 inception. Whether in fact, folklore or film, this icon of Northern American deserts has earned its legendary status.
