JANESVILLE
One of Janesvilleâs biggest, oldest, and arguably most historic oak trees is losing limbs, and the Rock County Historical Society is trying to figure out whyâand how to save the tree.
Officials said that during an otherwise windless and quiet night on Saturday, the giant bur oak tree on the northwest side of the historical societyâs Lincoln-Tallman Restorations grounds shed an enormous set of limbs. They snapped off and fell to the ground.
The oak tree, known locally as the "Witness Tree," has stood at the Tallman House property since at least the 1850s. The tree is believed to have been living when former President Abraham Lincoln visited the Tallman House in October 1859.
