66 FARM FORESTRY 



coniferous tree that occurs extensiveiy. The soil and climate 

 are well adapted to the growing of trees. Owing to the many 

 wood-using industries in the region and the demand for wood 

 products of all kinds, timber is of value. Many individual 

 trees of good form and quality bring high prices for special 

 purposes. Much planting has been done for posts and lumber. 

 The woodlots of the region are for the most part in a culled 

 condition, most of the valuable trees having been removed. 

 Wornout woodlots should be restocked and plantings started 

 on all the poorer soils of the farm. The upland forests con- 

 tain oaks, hickory, sugar maple, white ash, yellow poplar, bass- 

 wood, walnut, cherry and birch. The lowland forest contains 

 elm, red maple, black ash, sycamore, willow and gums. Many 

 of these native species are of value for planting. Black locust 

 and catalpa have been used extensively for posts. White pine, 

 Norway pine, yellow poplar, red oak, black walnut and white 

 ash all should be of value in planting for lumber. White ash 

 and green ash will grow well and furnish lumber and wood for 

 general farm purposes and for handles. 



The Prairie Region. — This region consists of three prin- 

 cipal divisions : the Western Prairie Region, including eastern 

 Montana, the Dakotas, south and western Minnesota and 

 northern Iowa ; the Middle West, including southeastern South 

 Dakota, Iowa, Nebraska, Kansas, eastern Colorado and west- 

 ern Illinois; and the Southern Plains, including Oklahoma, 

 southwest Kansas, northwest Texas and eastern New Mexico. 

 This is not a region of natural tree growth except along the 

 watercourses, owing to the lack of rainfall. Where trees are 

 started in forest plantings, however, and cultivated until the 

 crowns shade the soil, so that forest conditions are established, 

 there should be no trouble in raising valuable stands of trees. 

 There are in general two planting sites in this region, namely, 

 the uplands, consisting of exposed rolling prairies and plains, 

 and lowlands or bottomlands and lower valley slopes.
