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.

Artists have always been inspired by nature. We love to capture or create images of our favorite landscapes, animals, moments, and scenes. But well-practiced artists will tell you that nature can be more than just a muse. I have learned about the benefits of using skills taught to me as a naturalist to enhance my artwork. Nature observation and study skills are incredibly useful to any painter, illustrator, sculptor, or photographer.
I was recently asked to create a set of designs for enamel pins for the Arizona Master Naturalist Association. I have a moderate amount of experience with digital art, but this would be my first time attempting pin design. Pins require a unique art style because they have to use limited colors and have thick lines to accommodate the pin printing process and they need to get their point across in a very small space. I was faced with the challenge of creating art of something as complex as a California condor or ponderosa pine on a “canvas” about the size of a quarter.
Like many artists I started by looking at reference pictures of my assigned flora and fauna. This is where I began to use my naturalist skill of observation. During one of my winter field labs with the Pima County chapter of the Arizona Master Naturalists, we learned about nature journaling. We learned to look at an object, say a small plant, and try to draw it. This exercise seems easy enough if you sketch some abstract leaves in a few seconds — but will one of your classmates be able to guess what plant you drew if they see your drawing? This is where it helps to look — to really look — at your subject. In class we learned to look at the margins of the leaves, texture of the bark or stems, colors, veins, spines, thorns, shape, texture, and so much more. I then used these newly-learned observation skills with the pin designs. I observed how condors actually hold their wings when flying and how pine tree’s branches actually hang. The more I practiced focusing on all the details of my subject the better I became at recreating them in a way that others can also observe and understand.
The next naturalist skill I learned to employ in my art is interpretation. As naturalists we learn how to take the knowledge that we have and interpret it for a variety of audiences. How we present information on pollination to a group of master gardeners should be different than how we present it to fourth graders. This idea holds true for art. How I might draw a pine tree for a large mural is different from what I needed to accomplish for a pin.
Using these skills I began to create sketches of my subjects. I asked myself questions about what angle, scale, and even phenophase I should use. Should I interpret a bushy plant by drawing one entire bush, a clump of its leaves, or just a single flower? Should I interpret a bird perched calmly or soaring high above?
These four images are examples of the final designs I created for this project. Each subject was carefully observed, interpreted, and designed to best identify the species to any viewer. I chose two plant designs and two bird designs to share with you to demonstrate how I tackled similar organisms so differently. The skills I have learned as a naturalist are what allowed me to create these designs in this style, and I hope that you can also find ways to incorporate your skills into any art you create!

WHY WE, AS MASTER NATURALISTS, SUPPORT CLIMATE CHANGE ACTION
“Now is the time for science, not silence” (Scientific American, 10/8/2020).
Daily Global headlines and increasingly frequent observations of extreme weather events demonstrate that the science of climate change is all around us. The recent excessive heat and drought of our own Sonoran Desert provide abundant local evidence, as Tucson recorded both its hottest month and hottest year on record in 2020. As far back as 2011, the City of Tucson’s Climate Mitigation Report identified climate change as a threat to Tucson’s public health and safety, naming such hazards as wildfires, drought, flooding and extreme heat. As in other beleaguered cities, marginalized populations are most affected by climate change, and are most at risk.
On September 9, 2020, the City of Tucson declared a Climate Emergency, stating, “…a climate and ecological emergency threatens our city, region, state, nation, civilization, humanity and the natural world, and [we] recognize the need for bold action to combat climate change, so that it meets or exceeds the current recommendations of the foremost climate scientists working around the world.”(Resolution No. 23222,2020).
We, as the Pima County Chapter of the Arizona Master Naturalists, acknowledge that climate change is real, and we align with the scientific consensus that human activities are the main cause. We support the City of Tucson’s Climate Emergency Declaration and vow to support climate change action in our communities. Master Naturalists are a corps of trained and skilled volunteers who provide leadership in education, citizen science, and stewardship to all natural and cultural history organizations in Arizona, for the public good. We actively engage with our community in helping to create a sustainable world.
We are not isolated in our work; we understand the inter-connectedness of all life on Earth. As such, we support efforts here and elsewhere to address the serious issue of climate change, and we call upon our community and national leaders to strengthen their efforts and commitments to this crucial endeavor. Tucson’s recent Climate Emergency declaration acknowledged it clearly, “the United States of America has disproportionately contributed to the climate and ecological emergencies and thus bears an extraordinary responsibility to rapidly resolve these crises”.(Resolution No. 23222, 2020). We pledge to use our skills to further educate our community, to engage in the direct observations necessary for collecting citizen science data, to continue our stewardship and protection of the natural world, and to ensure that local climate change action is just and equitable. We urge you to join us and learn how you, too, can actively participate in addressing climate change.

On Saturday 11/14/2020 my trail partner, and fellow Master Naturalist, Deb Huie (C1) and I pulled our UofA/USGS trail cameras from the Huachuca Mountains. We’d been monitoring these sites for spotted cat activity (Jaguar and ocelot) since late 2016. Deb called it a “bittersweet day” because although it is a very tough 4 wheel drive approach and even harder hike we had grown to love this beautiful, remote area under all sorts of weather and conditions. But we also knew it was time for a new adventure. We’ll continue our Citizen Science work in the Whetstones.
While the Huachuca’s are excellent habitat for both cats we hadn’t had a detection on either of our sites since March 2017. The attached photos are of that individual male and, unfortunately, that of his eventual poaching when he returned to Northern Mexico. The rosettes on a jaguar’s coat are like fingerprints so individuals can even be recognized with a good photograph. This loss was heart breaking for us but also made us all the more determined to do everything we can to expand and protect their habitat in the U.S.
The Project (Directed by Dr. Melanie Culver) has cameras in all the major mountain ranges along La Frontera (The Borderlands) from the Baboquivaris to the Peloncillos. Many of the sites are remote but there are also some closer to Jeep roads and the Arizona Trail. We are always looking for dedicated volunteers. Film (SD cards) needs to be retrieved and batteries replaced (3-4) times a year.
Garden Canyon on Fort Huachuca is where we accessed our sites. One site was actually within Fort boundaries and the other was out a wilderness gate into the Coronado National Forest. The site on the Fort was complicated because…. well its the U.S. Army. Garden Canyon is a little known, but beautiful, recreation area that has tremendous hiking, birding and even pictographs. The area is open to the public on the weekends and during the week if there is no “live fire” on the Fort’s shooting ranges. Unless you have military privileges you’ll have to obtain a day pass at the Fort Huachuca Main Gate. But it’s easy to do! There are also some great museums on the Fort including one dedicated to the Buffalo Soldiers. Unfortunately no camping unless you hike past the Fort’s wilderness boundaries.
With one of our old sites above 8600 feet, we sometimes had to contend with some challenging conditions. Here’s Deb in February 2020 post-holing her way up above 8,000 ft.
This past Saturday was gorgeous although we probably missed ideal Fall foliage by about two weeks. Here are some of Deb’s pictures over the last couple of years.
Finally here are some examples of the abundance of wildlife on this incredible Sky Island.
