Coronado National Forest officials are looking beyond the current winter weather and seeing a fire threat posed by grasses in mountain ranges across southeastern Arizona.
Forest spokeswoman Heidi Schewel says tall grass blankets many slopes, allowing fires to spread rapidly once started.
The Arizona Daily Star reports that the grasses include invasive species that squeeze out native ones that are more resistant to fire.
Schewel says the Forest Service is reminding people to be careful with smoking materials when in the mountains.
