This course explores the role of fire as a natural disturbance in ecosystems. It introduces the concept of a fire regime and its influence on the type and distribution of organisms that occur in fire prone ecosystems. It also looks at some of the adaptations of plants that have evolved in these ecosystems and how animals either avoid or exploit the consequences of fire as a natural disturbance. Finally it examines how fire can increase biodiversity by generating a mosaic of habitats within an ecosystem and briefly addresses some of the consequences of climate change and global warming on the intensity and frequency of fires.
