Fens And Bogs In The Netherlands Vegetation History Nutrient Dynamics And Conservation

This volume focuses on the geology, land use history, palaeoecology, ecology and conservation of peatlands (fens and bogs) in The Netherlands. The volume provides detailed accounts that, together, give a representative picture of the studies that have been carried out in the Dutch mires over the past 25 years. Contents: Chapter 1: Verhoeven -- Introduction. Chapter 2: Pons -- is a comprehensive geographic and pedological account of peat formation in space and time in the western coastal plain. Chapter 3: Casparia and Streefkerk -- is a detailed description of the various stages of development from fen to bog of the Bourtanger Moor. Chapter 4: Borger and Stol -- details the history of peat draining, digging and dredging in The Netherlands and Flanders. Chapter 5: Barkman -- deals with bog remnants in the eastern Netherlands and northwestern Germany. This chapter also includes data on oligotrophic heath pools which have a vegetation that is similar to that found in bogs. Chapters 6: Den Held; 7: Van Wirdum et al.; 8: Koerselman and Verhoeven -- are chapters on vegetation, synecology and nutrient dynamics of fens and chapter 9: Wiegers -- focuses mainly on terrestrializing fens that are so characteristic of the western Netherlands where they presently occur in turf ponds created by peat dredging in former centuries. Chapter 10: Vermeer and Joosten -- concludes the volume with a treatment of problems with mire conservation and management.

This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described. Numerous successful projects are mentioned. In general ecological restoration endeavours greatly benefit from the progressive experience achieved in the course of the years. Failures mainly occur through insufficient application of physical, chemical or ecological principles. Spontaneous colonization by plants and animals, following habitat reconstruction, is preferred. However, sometimes the re-introduction of keystone species (e.g. eelgrass, salmon, beaver) is necessary in case the potential habitats are isolated or fragmented, or if a seed bank is lacking, thus not allowing viable populations to develop. Re-introducing traditional management techniques (e.g. mowing without fertilization, low intensity grazing) is important to rehabilitate the semi-natural and cultural landscapes that are so characteristic for The Netherlands.

A tribute to an essential part of our natural and cultural environment. 24 European cases studies written by international grassland experts. Thematic chapters provide essential background information on grassland fauna, the history of agriculture, grassland communities, the relationship between grasslands and climate and opportunities to conserve these grasslands of high nature value.

This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecol ogy addresses the relationships among spatial patterns, temporal pat terns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an import ant variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heteroge neous. Intellectual utility and applicability of results are valued equally. The International Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Preface In Europe, during the seventies, landscape ecology emerged as a fusion of the spatial approach of geographers and the functional approach of ecologists. The latter focused on ecosystem functioning, regarding eco systems as homogeneous, almost abstract units in space, with input and output of energy and matter to and from the undefined surroundings.

Forty-two chapters by international experts from a wide range ofdisciplines make The Wetlands Handbook the essential toolfor those seeking comprehensive understanding of the subject. Adeparture from more traditional treatises, this text examinesfreshwater wetland ecosystem science from the fundamentals toissues of management and policy. Introductory chapters address the scope and significance ofwetlands globally for communities, culture and biodiversity.Subsequent sections deal with processes underpinning wetlandfunctioning, how wetlands work, their uses and values for humansand nature, their sensitivity to external impacts, and how they maybe restored. The text is illustrated by numerous examples,emphasising functional and holistic approaches to wetlandmanagement, including case studies on the wise use andrehabilitation of wetlands in farmed, urban, industrial and otherdamaged environments, highlighting the long-term benefits ofmultiple use. The Wetlands Handbook will provide aninvaluable reference for researchers, managers, policy-makers andstudents of wetland sciences.

This handbook in two volumes synthesises our knowledge about the ecology of Central Europe’s plant cover with its 7000-yr history of human impact, covering Germany, Poland, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Czech Republic and Slovakia. Based on a thorough literature review with 5500 cited references and nearly 1000 figures and tables, the two books review in 26 chapters all major natural and man-made vegetation types with their climatic and edaphic influences, the structure and dynamics of their communities, the ecophysiology of important plant species, and key aspects of ecosystem functioning. Volume I deals with forests and scrub vegetation and analyses the ecology of Central Europe’s tree flora, whilst Volume II is dedicated to the non-forest vegetation covering mires, grasslands, heaths, alpine habitats and urban vegetation. The consequences of over-use, pollution and recent climate change over the last century are explored and conservation issues addressed.

This is a landmark study of the Holocene evolution and functioning of a suite of seasonal wetland basins in the temperate coastal zone of Western Australia, which were added to the the Ramsar List of Wetlands of International Importance because of their setting, their method of formation and deepening, their history of infilling, their complex hydrological mechanisms, and their dynamic hydrochemical and vegetation responses.
