What does purple paint on trees mean?
purple paint has been used successfully as a trespass warning for years by several other states. The use of purple paint to mark trees originated with forestry officials and is a popular method in other states such as Missouri and Arkansas. It also is being used in the East Texas forest region near Lufkin. Because purple paint has worked well with the forest interests, the action by the Texas Legislature was aimed at expanding its use to private agricultural land — such as the use of the paint by farmers and ranchers. the website I got it from is: http://www.texnews.com/biz97/jt090797.
