Under Seige



The Hemlock trees in the Great Smoky Mountains are under siege by Hemlock Woolly Adelgids.  Also, the fir & spruce trees are also being attacked by Balsam Woolly Adelgids.  
Every 6 months-1 year, the trees are sprayed in an attempt to get these bugs under control.  In 2002, the Park began releasing beetles as a means of controlling the outbreak of the Hemlock variety.
Smokiesinformation.org estimates that approximately 70% of the fir trees in the Park have been killed by the Balsam variety.  The hope is that a fir tree that is susceptible to the adelgid will be found to replenish what has been lost.

  1. Oh no! I never thought I'd feel sorry for trees - but I do now. :( I hope they find a way to save all the trees.

  2. All the trees at all the National Parks seem to be under seige of some bug or disease. It is so sad to see old trees die.
