Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Debris flow Hazards and Related Phenomena written by Matthias Jakob and published by Springer Science & Business Media. This book was released on 2007-12-26 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: With climate change and deforestation, debris flows and debris avalanches have become the most significant landslide hazards in many countries. In recent years there have been numerous debris flow avalanches in Southern Europe, South America and the Indian Subcontinent, resulting in major catastrophes and large loss of life. This is therefore a major high-profile problem for the world's governments and for the engineers and scientists concerned. Matthias Jakob and Oldrich Hungr are ideally suited to edit this book. Matthias Jakob has worked on debris flow for over a decade and has had numerous papers published on the topic, as well as working as a consultant on debris flow for municipal and provincial governments. Oldrich Hungr has worked on site investigations on debris flow, avalanches and rockfall, with emphasis on slope stability analysis and evaluation of risks to roads in built-up areas. He has also developed mathematical models for landslide dynamic analysis. They have invited world-renowned experts to joint them in this book.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The impact of low-intensity prescribed fires on slash pine/saw-palmetto/gallberry understory and forest floor nutrients was estimated from measurements before and after burning. Highly significant correlations existed between weight loss of these fuel components and the weight loss of several elements. Energy loss was also highly correlated with forest floor and understory weight loss. The data also indicate that annual or biennal burns do not reduce themacronutrients in the soil surface layer, but, in fact, increase them; and that even though a significant amount of N (110kg/ha) may be lost by burning a 5-year fuel accumulation there still is 160 kg/ha of N in the ash and residue following the fire, as well as about 700 kg/ha in the upper 10 cm of the soil profile.
