Challenges of regeneration

Restoring forests isn’t as simple as planting trees. Shifts in Colorado’s climate are challenging traditional recovery methods. Ecologists like Tony Cheng and Camille Stevens-Rumann point out the obstacles, from seed shortages to climate uncertainty, and the search for resilient tree species. “If you want a forest, what are you going to do to keep it there or have it there again?” Camille asks. 

 

The carbon connection

Forests are vital carbon sinks, because they store more carbon than they release, which helps with human-caused climate change. But when they're hit with beetles, drought, or severe fires, they can flip, and release more carbon than they store. 

“There are nine states in the Western U.S. that are net emitters of carbon from their forests, and Colorado is definitely one of them,” says Brian Kittler from American Forests. But there are strategies for reversing this trend, like targeted reforestation and carbon market incentives. 

Balancing science and values

Reforestation raises ethical and ecological questions: Should we restore forests to their past state, or plant for a warmer future? Tony Cheng also challenges us to consider the tradeoffs and figure out what success looks like. “What are we getting in terms of trying to reforest an area?” he asks. “Could we take those resources and do something else with them that might have a better return on investment for the environment, for climate mitigation, for the things that we care about?”
