Experiment marks trees for identification at low cost, suggesting bamboo culm provides durability.
In forestry work it is often necessary to mark trees for later identification. The question immediately arises as to how marking can be done with the least damage (current and subsequent), at low cost, and with some degree of permanence. The author describes an experiment in markingtrees with "nails" made of bamboo culm.
