发明名称 Biodegradable trail marker system
摘要 A system for marking trails including a visible tag having a unitary body of a planar configuration. The tag is made of a highly visible color with the body of the tag being made of a biodegradable plastic material. In use, a plurality of tags are fastened to foliage at regular intervals along a trail to provide a series of visible markers which define the trail. The tags are retrieved for reuse after the tags have served their intended purpose.
