Before revision: Dendrology – involves the study and identification of economically useful tree species Energy forestry – includes specifically managing for the production of energy from biomass or biofuel derived from a fast-growing species of tree or woody shrub Forest ecology – studies the patterns and processes of a forest ecosystem Forest economics – studies the impact of economics on forest management decisions Forest hydrology – embodies the effects of changes in forest land use on the movement, distribution, and quality of water in the ecosystem Forest inventory – incorporates quantitative measurements of the forest stand to determine stand timber volume and productivity/health, and provides a basis off which management decisions can be made
After revision: Forest pathology – study of diseases of woody plants, and of the interactions between trees and pathogens, pests, and other stressors that affect their health and function.Dendrology – involves the study and identification of economically useful tree species Energy forestry – includes specifically managing for the production of energy from biomass or biofuel derived from a fast-growing species of tree or woody shrub Forest ecology – studies the patterns and processes of a forest ecosystem Forest economics – studies the impact of economics on forest management decisions Forest hydrology – embodies the effects of changes in forest land use on the movement, distribution, and quality of water in the ecosystem Forest inventory – incorporates quantitative measurements of the forest stand to determine stand timber volume and productivity/health, and provides a basis off which management decisions can be made
