Table of Contents

The pecan is found as a forest tree in the moist bottom lands along the Mississippi river and its tributaries, from Indiana southward to Mississippi, and from Iowa to Texas and Mexico.

This region (see Fig. 1) in which the pecan is, or has been found, native, reaches its northern limit at Davenport, Iowa. It skirts the Wabash as far north as Terre Haute, Indiana, and along the Ohio river nearly to Cincinnati, Ohio. From thence its range extends south to Chattanooga, Tenn., and on to Vicksburg, Miss. From Vicksburg it skirts the Gulf of Mexico at a distance of seventy-five to one hundred miles to Laredo, Texas; thence along the Salado river into Mexico. The western boundary embraces the headwaters of the Colorado river and returns more or less directly to Davenport, Iowa. On the outskirts of this area, it extends farthest in all directions along the streams and rivers, while on the drier intervening ground the line does not extend so far from the center of the region. Particularly is this true in Southwestern Texas, where the pecan is confined almost solely to river bottoms.
