Conventional Forestry Practices That Manage for Timber Production

Conventional forestry practices that manage for timber production:

A) involve planting a collection of specific species of commercially important trees, but thinning or removing only those trees that are not ecologically desirable.
B) are reflected in the planting of a monoculture of young pines that are all the same age and are planted in rows a fixed distance apart.
C) reduce the use of insecticides and fungicides as managed forests are at less susceptible to disease and damage from insect pests.
D) increase forest diversity because managed forests offer a lot of one kind of food, and thus can support a larger variety of organisms than typically found in natural forests.
