Available in PDF, EPUB and Kindle. Book excerpt: Following the destruction of 95% of meadows during the twentieth century, there is an urgent need to understand what little unspoiled habitat remains in order to plan the management and restoration of existing sites, as well as re-creating future grassland habitats. This book is a much-needed guide to grassland restoration and management. Providing a thorough overview of recent research on grassland restoration and its implications for practical grassland restoration and management, it introduces grassland communities and the wildlife they support, including examples of species of conservation concern, and considers the management of semi-natural grassland habitats with particular emphasis on drier grassland habitats. Chapters cover: - Grassland character and communities - Introduction to grassland wildlife - Managing semi-natural grassland - Grassland restoration – threats and challenges - Opportunities in grassland restoration - Plant material for grassland restoration - Defining success in grassland restoration. A variety of management techniques are examined, including soil amendment, cultivation, harvesting and maintenance in creating suitable conditions for the successful restoration of species-rich grasslands. It is essential reading for conservationists, site owners or managers, practitioners, conservation organizations and students of ecological restoration with an interest in the creation of new grassland habitats, the restoration of semi-natural grassland, as well as the continuing management of semi-natural (unimproved) grassland communities.

Download or read book Control of bracken and the restoration of heathland V Effects of bracken control treatments on the rhizome and its relationship with frond performance written by R H. Marrs and published by . This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. The effect of three bracken control treatments on the rhizome system of bracken (Pteridum aquilinum (L.) Kuhn) at Cavenham and Weeting Heaths in Breckland was assessed. Control treatments included cutting once and twice yearly between 1978 and 1990, and spraying the herbicide asulam at the recommended rate (4.4 kg a.i. ha-1) in 1978 and 1985. In addition, the effect of continuous treatment was compared with plots in which bracken control ceased after 6 years. The effects on rhizome biomass and length, numbers of active and dormant buds, and starch and soluble carbohydrate concentrations were measured. 2. Cutting twice yearly was the most effective treatment, but rhizomes persisted even after 12 years of continous treatment. Cutting once yearly and applying asulam gave intermediate reductions in all rhizome variables. 3. Where bracken control ceased there was a relatively rapid increase in all measures of rhizome performance. At Cavenham Heath, remission for 4 years increased the starch levels in rhizomes, and after 6 years increased all rhizome measures. At Weeting Heath all measures were significantly increased 5 years after control treatments ceased. 4. Regression analyses showed that the majority of the variation in summer frond performance (0.39-0.75) could be explained by rhizome biomass. At both sites amounts of starch and carbohydrate in the rhizome, and at Weeting the above-ground grass biomass and total bud number, improved the fit of some equations. 5. Some earlier published data for Weeting Heath were used to estimate rates of rhizome depletion and recovery. Extrapolation from these results suggested that it would take (a) a further 8-34 years to eradicate bracken depending on treatment, and (b) between 9 years (for the cut once yearly and asulam treatments) and 62 years (for the cut twice yearly treatment) for the bracken rhizome system to recover its starting biomass. Moreover, a large frond biomass would occur before the rhizome system recovered com.

Download or read book Heathland seedbanks under bracken Pteridium aquilinum L Kuhn and their importance for re vegetation after bracken control written by R J. Pakeman and published by . This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In Great Britain, the regeneration of heathland and moorland plant communities after bracken control is slow and variable. Successful restoration depends on the availability of seed and the provision of suitable regeneration niches, as well as on the expansion of the plants previously present underneath the bracken canopy. This study investigates the availability of the seed resource of heathland species and its distribution, both in relation to increasing time since bracken invasion and with respect to its presence in litter or mineral soil. Calluna vulgaris was found to be the predominant species that germinated from the soil and litter beneath bracken at the sites studied. It appeared in greatest numbers from samples taken outside and at the edge of the bracken patch; numbers decreased deeper into the patch. Land which has been under bracken for a considerable period (>50 years) is likely to have a very reduced seedbank so that some form of propagule introduction, as well as litter disturbance, may be needed to speed up regeneration. On sites which have been invaded by bracken more recently, it is likely that litter incorporation into the soil would conserve the seed resource, whereas burning or litter removal would remove a significant proportion of that seed resource.

Download or read book The End of Tradition written by Ian D. Rotherham and published by Lulu.com. This book was released on 2014 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threats from global cultural change and abandonment of traditional landscape management increased in the last half of the twentieth century and ten years into the twenty-first century show no signs of slowing down. Their impacts on global biodiversity and on people disconnected from their traditional landscapes pose real and serious economic and social problems which need to be addressed now. The End of Tradition conference held in Sheffield, UK, was organised by Ian D. Rotherham and colleagues. It addressed the fundamental issues of whether we can conserve the biodiversity of wonderful and iconic landscapes and reconnect people to their natural environment. And, if we can, how can we do so and make them relevant for the twenty-first century. The book is in two parts: Part 1. A History of Commons and Commons Management and Part 2. Commons: Current Management and Problems.
Download or read book Sand Dune Conservation Management and Restoration written by J. Patrick Doody and published by Springer Science & Business Media. This book was released on 2012-09-17 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the development of temperate coastal sand dunes and the way these have been influenced by human activity. The different states in which the habitat exists both for the beach/foredune and inland dune are reviewed against the pressures exerted upon them. Options for management are considered and the likely consequences of taking a particular course of action highlighted. These options include traditional approaches to the conservation and management of wildlife and landscapes as well as habitat restoration. The way the value of the areas changes under different management regimes is considered mainly from an environmental perspective. Consideration is given to new approaches to management and restoration including adopting a more dynamic approach. Audience This book will be of interest to academics, students and professionals concerned with policy formulation and /or actively managing coastal areas.
Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two volumes of this handbook provide a comprehensive account of the emerging and vibrant science of the ecological restoration of both habitats and species. Ecological restoration aims to achieve complete structural and functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, reconstruction or re-creation is also included. Restoration in Practice provides details of state-of-the-art restoration practice in a range of biomes within terrestrial and aquatic (marine, coastal and freshwater) ecosystems. Policy and legislative issues on all continents are also outlined and discussed. The accompanying volume, Principles of Restoration defines the underlying principles of restoration ecology. The Handbook of Ecological Restoration will be an invaluable resource to anyone concerned with the restoration, rehabilitation, enhancement or creation of habitats in aquatic or terrestrial systems, throughout the world.
