Ecological succession is the process by which an ecological community undergoes an orderly and predictable change following a disturbance or initial colonisation of new habitat. This field study based program examines the theory of succession and how it remains at the core of ecological science. Students examine how changes may be initiated either by formation of a new, unoccupied habitat or by some form of disturbance of an existing community. There is an examination of succession events and their causes in various communities and ecosystems. Analysis data on population and community change is collected to examine the impact of human activity on various ecosystems.
