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.

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.

People rightly think of the jaguar as a resident of rainforest and jungle. But the secretive spotted cat is also native to the Southwest, including Arizona and New Mexico, and was confirmed during the twentieth century as far north as the Grand Canyon and Gila Wilderness.
