See a Manassas Witness Tree, Manassas National Battlefield Park, Virginia
At Manassas National Battlefield, A "Witness Tree" is a tree that was alive during the key events of the First and Second Battles of Manassas. To be a Witness Tree of the American Civil War these trees must be over 150 years old.There are hundreds of Witness Trees at the battlefield. For example, a common species in the park is Oak Trees which can live over 500 years!Park staff, with the help of a girl scout dedicated to completing her Gold Award project, identified a handful of these Witness Trees in the Battlefield along our trails systems. Will you be able to discover them all as you journey through the park?
The Witness Trees were located using historic maps and photos, aerial photography, and increment boring sample collection. Increment boring is a process of extracting a very small sample of a tree core with very little impact to the tree. The core sample is then analyzed by counting rings to estimate the age of the tree.
