Thursday October 11, 2007: Much of the giant Hemlock forests in the east are being killed by a very small insect called the Woolly Adelgid. The damage is more significant in Shenandoah National Park, where hemlock trees that are over 100 years old are being destroyed by this tiny sap-sucking insect that is native to East Asia. The insect was accidently introduced into the US in the 1920's, and is established in 11 eastern states from Vermont to Georgia. This is Clingman's Dome - the highest point in Great Smoky Mountains National Park, elevation 6,643 ft.

Hasnt anyone there heard of Pestides or Insecticides ..THEY WORK YOU KNOW!!
And I thought that tiny sap sucking insects were only found in the office where I work...
Mark- National Parks cannot use chemicals... nature must take its course.
CptJ- those sap-suckers manage the ballparks too!
