Invasions are natural ecological phenomena. Dispersing individuals encounter suitable habitat, establish, spread and evolve. In this way, species have radiated outwards from their origins, colonised distant offshore islands, and species have spread in response to changes in climate.

Human-induced invasions of plants, animals and diseases in modern times have dramatically altered the scales of time and distance over which invasions take place. Their impacts can be considerable, wiping out unique communities, endangering rare species, adding considerable costs to agriculture, horticulture and forestry, and having effects on the health, leisure and livelihoods of people. Tools such as pesticides and biological control can often be used to great effect, while for other invaders there are no obvious solutions. There may be unwanted side-effects of control methods on non-target species, they may adversely affect human health, and may cause considerable public concern. Integrated management strategies can be developed using ecological information about the species but these must be implemented in a real world that involves economics, politics, opinions and social interactions.

In this subject we will explore the underlying principles of biological invasions, analyse their impacts, discuss in detail the various control methods and consider their possible side effects Through developing a plan for a species of their choice, students learn to appreciate the interplay between science, technology, sociology and legislation in achieving successful management of invasive species.

One 5000 word report (80%, submitted in two parts), a management strategy for particular invasive species. One oral presentation (20%).

None

This subject is not available as a breadth subject.

On completion of this subject students should have:
skills in formulating and writing management plans; an ability to critically access different forms of information; an understanding of how management decisions must consider people and not just science
