Abstract

The northwest corner of Iowa has comparatively few native trees because of the xerophytic conditions which prevail there. The rainfall of this part of the state is the least in Iowa, at times going as low as eighteen inches for the year, and in exposed regions, the forest trees have been unable to obtain a footing. The native trees are nearly all found along the streams or in protected valleys. A good illustration of this is in Centennial Township in the southwestern corner of Lyon County, where the Big Sioux River flows in a westerly direction for several miles at the foot of a series of high bluffs. The north face of these bluffs is heavily timbered, and is the subject of this paper.
