"Beavers Work Hard For River Ecosystems"

"Development and climate change are top threats to wildlife habitat and biodiversity, and in the arid west, water supply is a consistent concern for all kinds of life. But ecologists see a simple, natural way for ecosystems to be more resilient: beavers.

When local ecologist Delia Malone walks along the Crystal River in Carbondale, she sees something missing. This footpath runs through an area that used to flood during spring runoff, but with the combination of development and climate change, it doesn’t anymore. Malone said it’s also in part because there are no beavers on this stretch of river.

“When we lose beaver, we also lose the wetlands they create, we lose the water storage,” Malone said. “Beaver dams store tremendous amounts of carbon. When beaver dams dry out because the beaver have left, that carbon goes up and is contributing to global warming.”"
