The Silent Invasion

  • Aired: 04/22/2008
  • 56:06
  • Rating: TV-G
Something troubling is taking hold in Oregon. Strange, exotic plants and animals are showing up in places where they don't belong. They are invasive species, and they're taking over landscapes, driving native wildlife away, and making everyone from ranchers to fishermen to wildlife managers nervous. What are these invaders? Where do they come from? And what can we do to stop them?
