Sending kids to Camp Colton at the base of the San Francisco Peaks has been a local tradition since the seventies. Thousands of sixth grade students have learned about science and nature there. But this spring there’s a new curriculum focused on forest health and wildfire prevention. KNAU’s Melissa Sevigny spoke about it with Ari Wilder, the executive director of Friends of Camp Colton.

Ten miles north of Flagstaff is the oldest experimental forest in the United States. It was established more than 100 years ago at a time when foresters wanted to know how to encourage ponderosa pines to grow. Now, scientists use Fort Valley to study the opposite problem: how to thin the overcrowded woods. It took decades of research to bring about that shift in thinking. KNAU’s Melissa Sevigny reports, it all started with one man and two mules.

Warming temperatures and drought are increasing bark beetle outbreaks worldwide, killing off thousands of miles of forests. The problem is so dire in Russia that foresters have enlisted the help of Flagstaff entomologist and bark beetle expert Rich Hofstetter.

A massive alligator juniper tree near Prescott is believed to be the largest and oldest of its kind in the world. It’s survived hundreds, possibly thousands of years of fire and drought. Forester Ben De Blois says the tree’s unique growth pattern makes it hard to tell just how old.

Nearly everyone who lives on the Colorado Plateau is familiar with the extensive pinyon-juniper woodlands. The stunted trees look tough and unbreakable, but the PJ community is fragile and slow to recover when disturbed.
