Large and intense wildfires are integral to the globallyimportant boreal forest biome. While much is known about borealwildfires, the focus on forest remnants that either escape orsurvive these intense fires is a recent phenomenon: academics nowstudy ecological processes of wildfire residuals, forestpolicymakers use their patterns to design harvest strategies,forest managers consider their economic value, and conservationistsrecognize their intrinsic ecological importance.
Ecology of Wildfire Residuals in Boreal Forests is thefirst book to explore ecological patterns and processes of whatdoes not burn within boreal wildfires. Following a briefintroduction to the boreal forest biome, it discusses the processesthat form wildfire residuals; how they are studied, with variousapproaches and methods; the types, extent, and ecological functionsof wildfire residuals; and their role in forest managementapplications, all in the context of ecological scale.
This book is a reference for researchers and graduate studentsstudying boreal forest ecology, as well as for policymakers andforest managers. It adopts a non-reductionist perspective that willbe of interest to scientists from conservation science, forestecology, forest management, and timber production.
* Brings together fire behaviour, ecological scale, vegetationecology, and conservation biology to provide a cross disciplinary,multi-scale, and an integrative discussion of forest fireresiduals
* Captures the state of knowledge with a meta-analysis ofresearch trends during the past few decades, with a comprehensivereview of the literature, a compilation of key references, and alist of key topics relevant to the study of boreal wildfireresiduals
* Identifies the major gaps and uncertainties in the present bodyof knowledge, including a critique of study techniques andreporting practices to date, and proposes a set ofterms and definitions and a list of research questions andpriorities
* Includes the authors' observations and researchexperience from boreal Canada, and information extracted frominteractions with North American and European ecologists, forestmanagers, and conservationists

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.
