One of those colors signal an extremely important warning when it comes to wildlife in the area.

Warning Colors On Trees

The U.S. Forest Service developed its color-coded system to help warn hikers of potential dangers to themselves and others in the woods. For example, a tree with the color red painted on it means the land belongs to the U.S. Forest Service.

Red on trees serves as a warning to those passing by that they are trespassing. It also helps reduce potential timber theft.
