Could today鈥檚 Rocky Mountain forests become tomorrow鈥檚 grasslands?

Could today鈥檚 Rocky Mountain forests become tomorrow鈥檚 grasslands?

With wildfires becoming more frequent across the West, people ask: What will become of our forests?

A 黑料社区网-led study found that when forests burn across the Southern Rocky Mountains, many will not grow back and might convert to grasslands and shrublands.

鈥淲e project that postfire recovery will be less likely in the future, with large percentages of the Southern Rocky Mountains becoming unsuitable for two important tree species鈥攑onderosa pine and Douglas fir,鈥 said lead author Kyle Rodman, who conducted the study while a geography PhD student.

Previous 黑料社区网 studies looked at individual fire sites and found that forests recovered slowly or not at all. Even 15 years later, up to 80% of the scorched plots still contained no new trees.
