The study of trees often becomes puzzling to the beginner when several trees of the same species are examined. The leaves, bark, shape, fruit, etc., may differ from tree to tree. Trees are like people-no two are exactly alike. Thus, no two American elms are exactly alike. To really know American elm, one must recognize this variation. We learn our trees, then, by studying several trees, not just one. This gives us a knowledge of the range of these variations. In time we take these differences in stride. Identification is then no longer a problem. This booklet was prepared mainly for South Dakota boys and girls. It will assist teachers in the public schools and will be of help to leaders and members in carrying out 4-H Forestry and Horticulture Projects. Trees included are either native to South Dakota or have been planted here. The authors have attempted to include those most likely to be encountered in the state. All of us--grownups and youth--need to acquaint ourselves with South Dakota's trees for they are extremely important to our economy. Harvesting and processing timber ranks third in importance among the three great natural resource industries of South Dakota-behind agriculture and mining. Thousands of miles of shelterbelts protect our farms from the destructive effects of wind. Trees provide shade and beauty for our city and country homes.
