Forests Service
Department of AgricultureThe following monologue is about some threats to the forests in America.
The Forests Service is responsible for the forests on public land in the US. It supervises almost 78 million hectares of forests, grasslands, rivers and lakes. It's an agency of the Department of Agriculture. Forests service officials say there are four major threats to forests and wild land in America. The first is the threat of fire and fuel. Fires are a natural enemy of forest growth, but they can also threaten lives and property. Fuel is dead plant material, and small plants that grow under tall trees. The Forests Service estimates that up to 1/4 of the forests it supervises have dangerous levels of fuel. Sometimes, foresters set controled fires to remove the fuel. Other times, the fuel must be cleared by hand.
