What reading level is Forestry An Elementary Treatise book?
To quickly assess the difficulty of the text, read a short excerpt:
If the competing species, which needs less light, has come in under the shade of the original stand, or along with it, the seedlings of the first species will be unable to grow in this shade, while those of the other will easily survive. The old trees might die with no survivors, and the site will belong to the competitor.
Tolerance. This ability to grow with less light is known as tolerance. Just as in the case of moisture, it is not beneficial to be deprived of light, but the less of it a tre...e needs, the greater advantage it has in the struggle for existence. Trees needing a great deal of light are intol- erant.
The tolerance or light requirements of different species are hereditary, and species may be classed according to their relative ability to endure shade. But it is not true that the same species always requires the same amount of light for vigorous growth. All other factors which in- crease the vigor of a tree tend to decrease the need of light. For this reason we find that young trees are more tolerant than old, the need for light steadily increasing as the tree grows older.
