This book focuses on fluxes of energy, carbon dioxide and matter in and above a Central European spruce forest. The transition from a forest affected by acid rain into a heterogeneous forest occurred as a result of wind throw, bark beetles and climate change. Scientific results obtained over the last 20 years at the FLUXNET site DE-Bay (Waldstein-Weidenbrunnen) are shown together with methods developed at the site, including the application of footprint models for data-quality analysis, the coupling between the trunk space and the atmosphere, the importance of the Damköhler number for trace gas studies, and the turbulent conditions at a forest edge. In addition to the many experimental studies, the book also applies model studies such as higher-order closure models, Large-Eddy Simulations, and runoff models for the catchment and compares them with the experimental data. Moreover, by highlighting processes in the atmosphere it offers insights into the functioning of the ecosystem as a whole. It is of interest to ecologists, micrometeorologists and ecosystem modelers.

After years of technological development and its important achievements to make our life easier and more comfortable, human society is going to face one of the most difficult challenges of the last century: to stabilize the concentra tion levels of greenhouse gases in the atmosphere to prevent harmful effects on the climate system. Through a delicate balance between photosynthesis and respiration, terres trial ecosystems, and in particular forests, are today thought to take up a sig nificant part of the carbon dioxide emissions in the atmosphere, sometimes called the "terrestrial carbon sink". However, the location, magnitude, and vulnerability of the carbon dioxide sink of the terrestrial biota are still uncer tain. The suite of traditional tools in an ecologist's toolbox for studying ecosys tem productivity and carbon balance include leaf cuvettes, whole-plant and soil chambers for gas exchange, and biomass and soil carbon inventories. While each of the cited methods has distinct advantages, they are limited with regards to their ability to measure net carbon dioxide exchange of the whole ecosystem across a variety of time scales. This book present a compendium of results of a European project (EURO FLUX), funded by the European Commission through its fourth framework program, aiming to elucidate the role of forests in continental carbon balance.

The aim of this book is to provide an accessible overview for advanced students, resource professionals such as land managers, and policy makers to acquaint themselves with the established science, management practices and policies that facilitate sequestration and allow for the storage of carbon in forests. The book has value to the reader to better understand: a) carbon science and management of forests and wood products; b) the underlying social mechanisms of deforestation; and c) the policy options in order to formulate a cohesive strategy for implementing forest carbon projects and ultimately reducing emissions from forest land use.

Climate change is one of the greatest challenges we face - both in terms of its potential impact on our societies and the earth, and the scale of international co-operation that is needed to confront it. Emerging as a component of the international dialogue on the environment and climate, the role of forests in influencing earth systems will need to be assessed. Drawing together perspectives from researchers and policy makers, this book explores how forests will interact with the physical and natural world, and with human society as the climate changes. Also considered is how the world's forests can be managed to contribute to the mitigation of climate change and to maximize the full range of economic and non-market benefits. Providing an examination of the science, a detailed consideration of the science policy interface and the international frameworks and conventions, this book is valuable reading for all those interested in sustainable forest management, climate change and the associated environmental sciences.

This book introduces a holistic synthesis of carbon and nitrogen fluxes in forest ecosystems from cell to stand level during the lifetime of trees. Establishing that metabolism and physical phenomena give rise to concentration, pressure and temperature differences that generate the material and energy fluxes between living organisms and their environment. The editors and authors utilize physiological, physical and anatomical background information to formulate theoretical ideas dealing with the effects of the environment and the state of enzymes, membrane pumps and pigments on metabolism. The emergent properties play an important role in the transitions from detailed to more aggregate levels in the ecosystem. Conservation of mass and energy allow the construction of dynamic models of carbon and nitrogen fluxes and pools at various levels in the hierarchy of forest ecosystems.

This book addresses global and subnational issues concerning the world's forests, societies, and environment from an independent and non-governmental point of view. Cooperation on a global scale is not only commendable, it is essential if solutions to the problems facing the world's forests are to be found. To achieve this, modern science needs to draw a clearer picture of relationships between forests, human activity, and the environment, and of the consequences of environmental change for the societies' development and growth. There are several - partly intermingled - evolutionary forest transitions underway: the slow transition from forest area decrease to an increase in the North while deforestation and degradation continues in the South. Although not all deforestation is considered negative, serious social, economic, and environmental costs may be associated with excessive deforestation. Deforestation control is just the first step on the stony path towards sustainable forest management. The forest management transition refers to the shift in the utilization towards managed semi-natural, secondary forests and plantation forests. There are some signs in the North of the forest paradigm shift from sustainable yield to forest ecosystem concepts. How deforestation can be tackled and how these concurrent transitions are effected will have profound implications for the future. These processes involve several challenges with South-North dimensions. A search for an optimum mix of public policies and markets is a global priority both as a forest policy issue and as an inter-sectoral item on the political agenda. Deforestation and transition is discussed here by a team of 14 scientists from both the North and the South. This book offers knowledge, facts, and information about world forests, society, and environment to help us towards equity in our use of the global forest – to create a clearer vision of unasylva.

A large area of Estonian hemiboreal forest is recovering from clear-cut harvesting and reflecting carbon (C) balance of the stand. Such a stand-replacing disturbance have considerable impact on forest ecosystems carbon dynamics, turning ecosystems from C-sinks into C-sources. Stands may require several years for recovery to C-sink status. For better understanding of net ecosystem CO2 exchange (NEE) we used eddy covariance (EC) method. EC technique gives opportunity to measure NEE in two different aged stands (6- and 8-year old stands), which are located in south-east Estonia, Europe. Studied stands which already were 6- and 8-years old, were acting as a light C-sinks. Mean summertime (June to September) measured NEE of both stands for 2014 was -1.536 u00b5mol m-2 s-1. In June, July, August and September NEE was -4.671, -2.254, -0.739 and -0.236 u00b5mol m-2 s-1, respectively. Measured mean CO2 concentration was 337.75 ppm and mean temperature was 15u00b0 C.Stands had similar patterns of carbon exchange and results showed clear correlation between C fluxes and ecosystem responses to environmental conditions. Weather conditions played a key role in the rapid rise in NEE results. NEE result was driven primarily by early-growing-season temperature and length. Meteorological data confirm ecosystem also depends on climate variability and water vapor.
