Our Land: New Mexico’s Environmental Past, Present and Future
The Future of the Forests
Season 6 Episode 29 | 5m 16sVideo has Closed Captions
Laura Paskus reports on New Mexico's forests conditions and what fires could occur.
This spring, the Sandia Mountains have received more precipitation than recent years, but they are still warming and drying over time. The forests are also overly dense, thanks in part to more than a century of fire suppression. And conditions are prime for what could someday be a catastrophic fire.
