58 OHIO EXPERIMENT STATION: MONTHLY BULLETIN 



all but the poorest soils and is adapted to the limestone areas of 

 southwestern Ohio. Its wood is light, strong and durable. It 

 compares favorably with the black locust in durability in contact 

 with the ground. The species should not be planted in close 

 proximity to apple orchards since it is the host of a fungous dis- 

 ease which is communicated to the apple. 



Trees not recommended. Certain species of trees have been 

 brought to the attention of landowners in various ways as being 

 promising for reforestation. The following are not recommended 

 for Ohio. 



Eucalyptus. The several species are not hardy in Ohio and 

 should receive no consideration by prospective planters. They are 

 suited only to portions of the Pacific Coast and the Southern states. 



Russian mulberry. The wood is durable but the tree is of 

 such poor form that it is not practicable to plant for timber. 



Silver maple, Acer saccharinum. The species is adapted only 

 to deep, moist soils. Its form is inclined to be poor excepting on 

 the strong soils. The wood is light, brittle and not durable and is 

 not of any considerable value. 



Box elder, Acer negundo. A species adapted to strong, moist 

 soils. The tree is of poor form, the wood light, soft and weak. 



The buckeyes and willows have but little commercial value and 

 their planting is not recommended for timber production. The 

 willows may be planted along streams to prevent washing. 



Nut trees. Some of the native nut trees may be planted for 

 the production of nuts. Nut culture, however, should not be com- 

 bined with timber production. To secure best results in nut yields 

 the trees should be spaced more nearly like the pomaceous fruit 

 trees. Close spacing is required in timber production and the yield 

 of nuts may be small or nil and their quality inferior. 



Yields from planted forests. Yields may be profitable under 

 Ohio conditions, particularly on inferior or 'waste lands. There 

 are other advantages in forest planting aside from the direct 

 financial returns. Potential value is each year added to every acre 

 of ground in growing forest. It is therefore an investment worth 

 while even though the owner does not harvest the matured crop. 

 The indirect influences of forest plantations such as windbreak, 

 shade and shelter, and the aesthetic effects all add value to the 

 farm which it is difficult to measure in actual money value. Again 

 moderate financial returns may be expected if progressive forestry 

 practices are adhered to and the plantations are established on 

 an economical basis.
