Abstract: A tree climbing support which includes as a first element, a body support characterized by a body support frame fitted with an adjustable top yoke which is designed to encircle a tree and adjustably support the body support on the tree. The tree climbing support further includes a foot support having a bottom yoke also adapted to adjustably encircle the tree and support the foot support on the tree below the body support. The tree climbing support is advanced up and down the tree by placing the feet on the foot support, with the body resting on the body support and traversing the tree in inchworm fashion by alternately moving the body support and foot support along the tree trunk. The body support and foot support are constructed and sized to facilitate nesting of the foot support inside the body support for transporting the tree climbing support in backpack fashion, on a motorcycle, or in a small all-terrain vehicle.
