Classification Based on Successional Stage

Communities that invade recently abandoned land or pasture, or other disturbances that destroy the structure of the mature forest, are called successional forests. Budowski (1965) listed the characteristics of early, middle, and late successional species (Table 3.2). Early successional species are often characterized as fast growing. Although secondary forests grow fast in volume, most pioneer tree species have wood of low specific gravity, sometimes 0.3 or less (Jordan and Farnworth 1980). This makes them more valuable for uses such as pulp. Species with fast volume increment also are desirable for land
