The Liberty Tree is a live oak (Quercus virginiana) that was relocated from the southern part of the WDW property during initial construction. At the time, it was one of the largest trees ever transplanted. Two holes were drilled through the trunk of the tree through which were inserted heavy steel dowels that served as the attachment points for a crane. After replanting, the dowels were removed and replaced by the original wooden plugs. The original wood had become contaminated, however, and the tree developed an illness which threatened its survival. The WED landscapers removed the wooden plugs and the diseased portion of the tree and refilled this space with concrete, allowing the tree to continue to grow. Another smaller live oak was also grafted onto the Liberty Tree at its base to further its appearance.
