220-160 Forest Botany and Ecology

This subject introduces ecological concepts and the importance of ecological balance in forest management. On completion of this subject, students should:

• understand basic plant structure, the terms used to identify trees and be able to identify common tree species;

• be familiar with plant classification and systems used to classify plants;

• understand the fundamentals of tree growth and forest structure;

• be familiar with the principle of niche theory, inter and intra-specific competition, diversity and species richness; and

• have an appreciation of the processes influencing community diversity and structure and ecosystem stability.

This subject covers:

• basic plant structure, classification, taxonomy and identification.

• functional relationships, trophic levels, microenvironment, adaptation, habitat and niche;

• limiting factors, variability and diversity of forest populations, spacing, territoriality and social hierarchies;

• population growth and development of forest stands;

• community structure and species composition, interaction within the community and the external environment; and

• community change, succession and ecosystem stability and response to manipulation.

A 2-hour examination worth 40% and up to five practical exercises totalling 60%.
