Helps you explore ecological patterns and processes of what does not burn within boreal wildfires. Following a brief introduction to the boreal forest biome, this book discusses the processes that form wildfire residuals; how they are studied, with various approaches and methods; and types, extent, and ecological functions of wildfire residuals.

Ajith H. Perera is a senior research scientist and leads the Forest Landscape Ecology Program at the Ontario Forest Research Institute in Ontario, Canada. He has over twenty-five years of research experience in landscape ecology, much of it focused on understanding patterns and processes of boreal forest fire regimes. He has authored many scientific publications, including several books. Lisa J. Buse is a forest biologist who specializes in knowledge transfer at the Ontario Forest Research Institute. She has over twenty years of experience in communicating forestry sciences to practitioners, especially on forest landscape ecology including wildfire disturbances in boreal Ontario. She has also published many scientific publications and co-edited three books.
