Excerpt from Manual of Forestry, Vol. 2: Formation and Tending of Woods, or Practical Sylviculture In each of these and other cases, the particular species of tree to be grown and the method of treatment are likely to differ, and it is the business of the forester to select those species and methods which realise the object of management most fully and in the most economic manner. More especially, the forester must always consider what. Effect the species and the selected method of treatment are likely to have on the property, and he must remember that any exceptional strain put upon the soil for more than a limited period, in order to realise an exceptional effect, must be followed by a correspond ing period of relaxation. Unless this is given, the soil, in the majority of cases, will deteriorate, and it may ultimately become absolutely sterile. Such an exceptional strain may suit the special requirements of a particular owner, but is not in the interest of the general community. Political Economy teaches that the correct mode of procedure points to the care ful preservation of the productive powers (or factors) of any given locality, so as to render possible the production of the same effect, or an increased one, regularly and indefinitely. Experience has shown that in forestry the safest method of preserving the productive powers of a locality consists in maintaining uninterruptedly a crop of forest vegetation on the area. The more frequently and the longer the ground is uncovered and exposed to the full effects of sun and air currents, the more, in the majority of cases, is the productive power liable to be reduced.
