RAVEN’S NEST

BIODIVERSITY IN THE HEART OF THE SKY ISLANDS

Set in the incomparable Sky Islands of southeast Arizona, Raven’s Nest is our private, 42-acre Nature Sanctuary – situated near the quaint town of Patagonia and a 4-minute drive from Patagonia Lake State Park. Raven’s Nest is strategically located by over 9,500 acres of pristine wilderness in Sonoita Creek State Natural Area. Our preserve hosts a secluded and engaging Mesquite Woodland, where you will enjoy sublime luxuries in our Safar Camp – all-the-while in the embrace of the Earth, serenaded by the songs of countless birds, and treated to a diverse array of wildlife. With over 5 miles of groomed Nature Trails to enjoy at Raven’s Nest Nature Sanctuary you’ll soon discover its unique biodiversity in the heart of the renowned Sky Islands!

The Sky Islands of Arizona are truly a natural wonderland, filled with surprisingly diverse landscapes and a profusion of flora, fauna., and fungi. Towering and dramatic mountain ranges loom like forested “islands” – each with a distinct complement of biota – isolated from each other by intervening “seas” of deserts and grasslands. The Madrean Archipelago is the most diverse temperate Sky Island in the world.

ARIZONA’S SKY ISLANDS

Six different biological provinces converge in this region: Rocky Mountains, Sierra Madre, Sonoran Desert, Chihuahuan Desert, Great Plains, and Neo-tropics. One of only 20 such Sky Island complexes on Earth, our Madrean Archipelago – named after the nearby Sierra Madre Mountains in Mexico – harbors a truly stunning array of flora and fauna, many unique to this area of the world. Here is where the temperate Rocky Mountains suffuse with the subtropical Sierra Madre mountains of Mexico, and where the Great Plains and Chihuahuan Desert to the east intermingle their ecological influences with the Sonoran Desert to the west. This rare convergence of temperate and tropical biomes, when combined with our relatively low latitude and ample elevational changes in the mountains, provides a one-of-a-kind arrangement in the natural world.

In the heart of this Madrean Archipelago the Patagonia Mountains and Sonoita Creek are world-class biodiversity hotspots supporting a myriad of mammals, birds, reptiles, amphibians, invertebrates and a dazzling array of native plants. Therefore, with only about 20 such Sky Island complexes known on Earth, we are truly in an exclusive category! Here you can experience our world-renowned biodiversity firsthand, including:

Over 500 species of Birds – many more typical of Mexico and the tropics including:
18 species of Hummingbird
12 species of Owl
~23 species of Hawks and Vultures

Over 2000 species of Plants
108 Mammal species – more than any comparable area in North America and including species more characteristic of the Neotropics such as White-nosed Coatis and Mexican Long-tongued Bat

Further, many of our local species are found in few or no other places in the U.S. White-nosed Coati, Collared Peccary, Elegant Trogon, Gray Hawk, Sonoran Toad, and Desert Tortoise are but a few of the unique wildlife species you may encounter while exploring the Sky Islands. While you’re unlikely to see them, we’ve also made international news of late with multiple Jaguar and Ocelot sightings nearby. These tropical cats remind you that a trip here is essentially an exploration of northern Mexico – minus all of the hassle. You may choose Nature Adventures in the Sonoran Desert, Chihuahuan Desert, lush Grasslands, swamp-like Cienagas, Chaparral, Madrean Evergreen Woodland, Pine Forest, and even Spruce-Fir Forest reminiscent of Canada. Truly there is something for everyone here!

All of this and more in an area with a bewildering choice of wild areas to explore. In addition to time spent at one or both of our Nature Sanctuaries – Raven’s Nest and Raven’s Mountain you may greatly enjoy venturing into one or more of the nearby wild areas.
