Earth Notes

The Colorado Plateau is one of North America’s human and environmental treasures. Ancient cultures have called this land of sun-baked deserts and lush mountain landscapes home for centuries. Earth Notes, KNAU’s weekly environmental series, explores the Plateau by telling stories of the intricate relationships between environmental issues and our daily lives.

Rooted in science and wrapped in human interest, the two minute long segments encourage listeners to think of themselves as part of the solution to environmental problems. Upbeat and informative, the program tries to foster hope and dampen despair about the environment, and motivate listeners to become more conscious and informed stewards of the Colorado Plateau.

On Halloween, all you ghosts and goblins will want to beware of the beautiful but deceiving  lady, the tarantula hawk wasp. She’s dressed up in shining blue-black with gossamer orange wings, her antennae elegantly curled.

When the Slide Fire hit Oak Creek Canyon in 2014, biologists were gravely concerned for the resident population of threatened narrow-headed gartersnakes.

Reconciliation ecology is a way to live in places we have already touched. It’s a strategy that acknowledges human presence, yet enhances the environment and improves wildlife habitat.

Chaco Canyon National Historical Park is noted for amazing structures called Great Houses – massive buildings constructed by the Ancestral Puebloans, who inhabited the nearly treeless high desert of northwestern New Mexico a thousand years ago. Besides local stone and earth, nearly a quarter million trees were harvested for beams in the buildings.

This year marks the centennial of the Migratory Bird Treaty, an agreement signed in 1916 to help conserve, protect, and manage migrating birds and their habitats throughout the U.S. and Canada. The 100th anniversary is a reminder that such birds play vital ecological roles. They are also good indicators of the health of our environment.
