ADVICE FOR FOREST PLANTERS IN OKLAHOMA AND ADJACENT 



REGIONS. 



THE REGION. 



The region to which this publication is devoted lies between the 

 thirty-third and thirty-eighth parallels and the ninety-sixth and 

 one hundred and fourth meridians, and embraces approximately 

 100,000 square miles. It includes all of Oklahoma and portions of 

 Indian Territory, Kansas, Colorado, Texas, and New Mexico. In 

 order to show the relative distribution of the rainfall and the physi- 

 ographic features that influence the choice of species for planting, 

 the region has been divided into four belts, named, respectively, the 

 Lowlands, Cross Timbers, Red Beds, and Plains. These belts are 

 shown on the accompanying map. Their boundaries have been made 

 to coincide with the even thousand- foot contours, since those inter- 

 vals represent quite truthfully the varying character of the forest 

 growth. 



The Lowlands Belt is so named because a large part of its surface 

 is occupied by broad, flat river bottoms; the Cross Timbers Belt is 

 named from the Upper Cross Timbers of Texas, which extend into this 

 belt from the south; the Red Beds Belt is named from the geological 

 formation prevailing in western Oklahoma and the eastern part of 

 the Texas " Pan Handle " ; and the Plains Belt is named from the 

 high plains which extend from western Texas northward along the 

 eastern front of the Rocky Mountains. 



FOREST SUPPORTING CAPACITY OF THE REGION. 



For several years past the Forest Service has been cooperating 

 with farmers in making forest plantations. It has made planting 

 plans for seventy-six landholders in Oklahoma and adjacent regions, 

 in accordance with its Circular No. 22, and the information here pub- 

 lished has been collected by the agents of the Service chiefly in con- 

 nection with the making and execution of these planting plans. 



A planting plan, as prepared by the Forest Service, is a detailed 

 statement of all the operations necessary to establish and maintain 

 a forest plantation upon a specific tract of land. Before a plant- 

 ing plan of value can be made, the nature of the soil and subsoil of
