Science and Innovation

Many parts of the Colorado Plateau are covered with distinctive soil crusts. Scientists are learning more about how they aid ecosystems—especially by providing good places for plants to grow.

Soil crusts rely on tiny organisms called cyanobacteria that are good at colonizing bare soil. In cold regions, frost heaving can give a dark, pinnacled appearance to soil covered with cyanobacteria. And that complicated micro-topography is key to what comes next.

With bee populations declining worldwide, news is often grim in the world of bee research. But last August, entomologists from the University of California at Riverside found something to cheer about: they spotted three members of a bumblebee species long feared extinct.

Last documented in 1956, the Cockerell’s bumblebee of south-central New Mexico is the country’s rarest bumblebee.

Earth Notes: Blackbrush

Mar 7, 2012

What can a small, inconspicuous shrub tell us about climate change in the Southwest? That’s the question researchers are asking about blackbrush.

Most people don’t take a second glance at this compact, slow-growing shrub bristling with spiny, gray-black branches. Yet it grows across several million acres in the Mojave Desert and up onto the Colorado Plateau, sometimes in nearly pure stands. You can see extensive swaths in Arches and Canyonlands, and over the Tonto Plateau in Grand Canyon.

In a cold, high-elevation Colorado valley, a food renaissance is taking place. The Mountain Roots Food Project aims to create a resilient local food system through which a diverse community can learn, participate—and be fed.

Earth Notes: Eddie McKee

The Grand Canyon has always attracted people who fall deeply in love with the landscape and its lessons. One of those who made the place his life’s work was Edwin Dinwiddie McKee.

Born in Washington, D.C. in 1906, McKee was influenced by his scoutmaster Francois Matthes, an early Grand Canyon mapmaker. A summer paleontology internship at the canyon was all it took to ignite young Eddie’s life-long love affair with geology.
