Abstract: A tree trunk protector includes a pair of elongate upright members, each of which has opposing end portions. Each of the upright members defines a pair of upright edges such that respective pairs of the upright edges are engageable with one another to form an elongate opening suitable to surround the lower portion of the tree and the elongate opening is substantially the same size along the length of the upright members. Each end portion of each of the upright members defines a respective integral flange that includes a pair of faces where respective pairs of the faces are in face to face abutment when the upright edges are engaged with one another. Each of the faces of the integral flanges define a projection and a hole located such that the projection of one flange is engaged in the hole of another flange when the upright members are engaged with one another.
