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.

The fire ecology course was exceptionally informative and engaging. I gained a deep understanding of the intricate relationship between fire and ecosystems. The instructor's passion for the subject was evident in every lecture, making the material come alive. The field trips and hands-on activities further enriched my learning experience. I feel more equipped to address the complexities of fire management and conservation. Overall, this course has been a valuable and enlightening journey into the fascinating world of fire ecology and very helpful to understand climate change and its consequences.
