Global cover of forests–this map shows the forests classified into three categories–tropical forests, temperate deciduous forests, and temperate-boreal coniferous forests. This shows all forests, whether they are protected or not.

WCMC calculated the amount of forest coverage in different regions of the globe, andalso how much in each region was protected.

North America, Russia, and South America have the highest coverage of forests. Russia had the lowest percentage protected, at 2 per cent, while insular Southeast Asia had the highest, at 17 per cent. The United States has about 10 per cent of its forest protected.
Here’s the forest map for the eastern United States, which also shows protected areas (red dots).

Almost all countries show a decline in the forest/people ratio, but a couple of regions show an increase. The greatest decline is in Continental South and Southeast Asia.
How do we treat our existing forests? We can manage them, or we can mine them. Leaving them alone is one form of management.
Silviculture is the theory and practice of controlling forest establishment, composition, structure, and growth.
While the way we treat our publicly owned forests is highly regulated, there are fewer laws that protect privately owned forests from being mined.
Your book discusses some silvicultural practices. Its discussion is too simplistic, and really, there are good points and bad points to most types of forest management practices. The handout does a more thorough job of helping us understand these practices. It is taken from a book by Mac Hunter called Wildlife, Forests, and Forestry.
