Abstract: A semi-rigid tree protector positionable about a circumference of a base of a tree, the base of the tree having a circumferential outer surface. The tree protector comprises a corrugated band mechanism for encircling the circumference of the base of the tree. The corrugated band mechanism includes a series of alternating ridges and grooves extending substantially vertically of the base of the tree when the band mechanism is positioned therearound. The band mechanism being made of materials which are sufficiently flexible and resilient to permit the band mechanism to be bent around the tree. Preferably, the grooves are reciprocated by vertically extending surfaces. Preferably, the band mechanism includes first and second ends, and a coupling mechanism for coupling the first and second ends together around the base of the tree. Methods of protecting the base of a tree from the impact of lawn care equipment and from plant eating pests and animals are also provided.
