Abstract
Abstract A protector for surrounding the base of a trunk of a tree (18) includes a base (2), a barrier wall (4) and, a slit (10) which extends, on a centerline, through the major portion of base (2). The central portion of base (2) is defined by a plurality of cresent shaped flaps (2), each attached to the next by a hinge (14), on each side of the centerline (10). The central base structure allows for case of installation and provides for tree growth while allowing capture and permeation of liquids held in the reservoir defined by the barrier wall (4) to the root zone. An outwardly directed flange (6) on base (2) serves as a mower track which can be anchored by pins (20) through punch out holes (24) defined on flange (6).
