Conserving Bogs

Bogs are fascinating landscapes for ecologists, climatologists, archaeologists, environmental historians and water managers. But many bogs have been damaged, and legislative protection - as 29 case studies demonstrate - is not enough to conserve the rest.

Despite our growing awareness of the vital role they play in the global environment, wetlands remain among the most endangered ecosystems on Earth and are still being destroyed and degraded at an alarming rate. This much-needed publication, which includes contributions from leading researchers and practitioners, presents a holistic perspective on the restoration of wetland ecosystems such as shallow lakes, streams, floodplains and bogs. Through the use of carefully chosen case studies, the authors examine European wetland restoration projects from Scandinavia to Bulgaria and from Ireland to Belarus, focusing on the lessons they can teach to a new generation of conservationists. As well as reviewing the sum of current knowledge on the subject, the text is a store of practical know-how, covering a wide range of conservation approaches and techniques. It analyzes the major problems in the field and identifies key principles for achieving sustainability in wetland restoration. The topics covered include: • the role of wetlands in landscape functioning • human interference with natural processes such as water and matter cycles and energy dissipation • the impact of land use on global problems such as climate change, floods and droughts • the role played by diversity in wetland functioning The work shows that without sustainable land use over the totality of their catchment areas, and without cohesive inter-agency cooperation, individual restoration projects will have a short life span. The balance between scientific background and practical restoration makes this book a valuable resource for scientists as well as wetland managers, decision makers and land use planners, as well as students of ecology, nature conservation and environmental protection.

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.

The bog turtle (Clemmys muhlenbergii) is variously considered to be secretive, uncommon, or threatened with extinction. It has a disjunct distribution in the eastern United States, and populations are restricted to wetlands such as bogs and swamps. The turtle appears to be an omnivore. It is most active in the spring, and the eggs (usually three to five) are laid in late spring or early summer. Sexual maturity in both sexes probably occurs at the plastral length of about 75 mm., when the turtles are 6 to 8 years old. Bog turtles apparently have small home ranges (about 1.3 ha or smaller). Other population features are poorly known. There is concern for the plight of the bog turtle because of the continual loss of wetland habitat and irresponsible collecting. A thorough survey is recommended to delineate the occurrence and abundance of the remaining populations of the species throughout its range.

How has Irish nature been studied? How has it been expressed in literature and popular culture? How has it influenced, and been influenced by, political, economic, and social change? These long-neglected questions are pursued in Nature in Ireland, a pioneering collection of original essays by leading naturalists, science writers, and cultural historians who bring us from the geological prehistory of Ireland to the environmental threats of the late twentieth century.

This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.
