Weeds cause problems at Danie Boone National Forest
Federal forestry officials say they're preparing to tackle the weeds in the Daniel Boone National Forest.
The agency says the forest "is facing an ecological crisis," as native species are crowded out by aggressive foreign plants. There are more than 70 species of plants from Asia and Europe that are causing problems.
The agency proposes to get rid of weeds by pulling, mowing, burning or spraying them with herbicides.
The Forest Service plan calls for treating up to 1,400 acres a year. The cost to treat the forest has not been released.
