56 OHIO EXPERIMENT STATION: MONTHLY BULLETIN 



portion west of the counties of Erie, Huron, Richland, Knox, Lick- 

 ing, Fairfield, Ross, Pike and the sandstone area of Adams. Ex- 

 ception may be made of certain areas in northwestern Ohio, where 

 the soils are sandy or sandy loams. The so called "openings" in 

 Lucas and Fulton Counties are especially noteworthy, as being 

 adapted to evergreen species. Evergreens, however, may be em- 

 ployed in the formation of windbreaks in almost all parts of Ohio 

 where such is the sole purpose of the planting. 



A number of species of conifers and evergreens are promising 

 and may be planted within the State, but more is known of the 

 merits and characteristics of those following and it is suggested 

 that selections be confined to this list. 



Red pine, Pinus resinosa. Red pine is a native of the north- 

 ern states and Canada, and is of moderately rapid growth. The 

 wood is heavy and strong. The species will grow on the thinnest 

 and driest soils, and is one of the best evergreens for planting. It 

 will not thrive on heavy, wet soils. Red pine is well adapted to 

 planting on abandoned fields and eroded hillsides. It is intolerant 

 of shade, of good form, and is fairly well suited for windbreak 

 purposes. 



White pine, Pinus strobus. Commercially, white pine is the 

 most valuable of the pine timber trees. It is a rapid grower and 

 adapted to practically all soils of the hill sections of the eastern 

 half of the State excepting the heavy clays. The white pine un- 

 fortunately is subject to fungus troubles which makes it impossible 

 to unqualifiedly recommend it for general planting. Owing to the 

 isolated plantations in Ohio, the danger of infection from the pine 

 blister rust is not as great as in some of the other states. 



Pitch pine, Pinus rigida. Pitch pine is a native of southern 

 Ohio. It is well adapted to the old fields in that section and has 

 merit in that it is adapted to heavier soils than most other pines. 

 Its growth is moderately rapid excepting on the poorest sites ; it is 

 easily transplanted. At present it is recommended for southeast- 

 ern Ohio and on the poorest sites. Its wood is heavy, resinous and 

 strong. 



Scotch pine, Pinus sylvestris. Scotch pine is a native of 

 Europe and is planted extensively on that continent. It is a 

 species of rapid growth, particularly in youth. It tolerates quite 

 a wide range of soils, and is adapted to all but the heaviest clay. 

 The wood is strong and heavier than that of white pine. The tree 

 sometimes developes poor form in later years. It is well suited for 

 planting on abandoned fields.
