Abstract

The forest area in Illinois to which this report applies is bounded by the Mississippi River on the west and the thrid principal meridian on the east, and extends in a north and south direction from Thebes, in Alexander county, to Chester, in Randolph county. It comprises all of Jackson county and portions of Union, Alexander, Pulaski, and Randolph counties, a total of 697,286 acres. It forms the western part of the Ozark highlands of southern Illinois (Colyer, '22), a region which extends across the state for 75 miles, with an average width of about 25 miles, from the mouth of the Big Muddy on the Mississippi to Shawneetown on the Ohio.
