Book Description
Abstract: The forests of northern California experienced frequent, low-intensity fire prior to Euro-American settlement, but more than a century of grazing, logging and fire suppression has resulted in changes in tree community structure that contribute to infrequent, high-intensity fires in these forests today. Although ecosystem restoration for reduction of wildfire hazard has received substantial attention in recent years, many ecological questions remain unanswered. For example, it is not yet clear how large-scale forest manipulations, such as reduction of tree density via forest thinning or prescribed fire, differentially affect soil fertility, nor how impacts on soil nutrient availability in turn affect forest productivity. My research in the Klamath National Forest of northern California investigates the impacts of experimental restoration treatments (prescribed fire, mechanical thinning, and their combination) on soil physical, chemical and microbial parameters and forest floor C and N content, and the time lag and duration of response of leaf nutrient concentrations of two dominant tree species to each treatment. Results showed that significant differences existed among treatments in terms of soil nutrient status and microbial activity, with the effect of fire either mediated or enhanced by thinning; however, for most variables the magnitude of effect was small. Prescribed fire had different effects on soil nutrients and microbial activity in unthinned areas than in areas that had been mechanically thinned prior to fire, and the species composition of trees that remain following thinning significantly affected soil nutrient availability and forest floor C and N content. Thinning also affected conifer needle nutrient concentration and size whereas fire alone does not, and the time since treatment as well as the magnitude and direction of response differed between tree species and among treatments. These results provide an intermediate-term evaluation of the effects of fire and thinning on soil and vegetation, and increase understanding of the link between the above- and belowground components of a mixed-conifer ecosystem. This study contributes to an ecosystem-level understanding of forest restoration strategies, and provides information that is directly applicable to fire and forest management policies in the western United States.
Fire Effects on Soil Properties

Book Description
Wildland fires are occurring more frequently and affecting more of Earth's surface than ever before. These fires affect the properties of soils and the processes by which they form, but the nature of these impacts has not been well understood. Given that healthy soil is necessary to sustain biodiversity, ecosystems and agriculture, the impact of fire on soil is a vital field of research. Fire Effects on Soil Properties brings together current research on the effects of fire on the physical, biological and chemical properties of soil. Written by over 60 international experts in the field, it includes examples from fire-prone areas across the world, dealing with ash, meso and macrofauna, smouldering fires, recurrent fires and management of fire-affected soils. It also describes current best practice methodologies for research and monitoring of fire effects and new methodologies for future research. This is the first time information on this topic has been presented in a single volume and the book will be an important reference for students, practitioners, managers and academics interested in the effects of fire on ecosystems, including soil scientists, geologists, forestry researchers and environmentalists.
