Fire regimes refer to the patterns and characteristics of wildfires within a particular ecosystem over time. This research area focuses on understanding the frequency, intensity, and severity of fires in a given region, as well as the ecological impacts of these fires on vegetation, wildlife, and habitat. Researchers study factors such as climate, vegetation composition, topography, and human activities that influence fire behavior and occurrence. By studying fire regimes, scientists can better predict and manage wildfires, protect wildlife and ecosystems, and promote healthy fire-adapted landscapes.
