The Texas Forest Service continues to assist clubs and schools in organizing Arbor Day programs. STATE TREE The pecan, _Carya illinoensis_, (Wangenh.) K. Koch, was officially designated as the state tree of Texas by an act of the legislature in June 1919. By an amendment in 1927, certain state agencies were requested to give due consideration to the pecan tree when beautifying state parks and other public property belonging to the state.

The following is a guide or lesson plan that will help make a friend of each tree studied.
