Tree Label

To identify which tree is which, I decided to use an aluminum cat food can lid and punch in the tree code and tie it to the base of the trunk for now with wire. When the tree is substantial enough I will fasten it into the trunk at BH or breast height which is 4.5 feet above ground standing up hill or around 1.5 metres. Aluminum is a preferred metal for labels since it doesn't rust and will probably last a good 30 years.
