Why are they dangerous?

• Threaten wildlife

       Because the can out-compete native plants and provide few resources            themselves, they reduce the habitat quality for native animals.

• Diminish outdoor recreation

       Because the can cover trails and landscapes, they reduce the outdoor             enjoyment for horseback riders, hikers and birders.

• Increase chance and wildfires

       Because the produce more fuel for fires than the natives they replace,              they increase the chance of a catastrophic wildfire.

• Reduce water resources

       Because the can consume enormous quantities of water, they reduce the         supply available to native plants animals and humans.
