This report presents the results of the statistical analysis of the enlarged dataset following the first comprehensive classification scheme for standing waters in Britain
The UK Biodiversity Action Plan and the EC Habitats Directive aim to conserve specific types of habitat by means of action plans and site protection measures. In order to set natural resources in context, to enable planning to be effective and to facilitate the costing of proposals for action, it is necessary to know the extent of each habitat type. The total surface area of standing fresh water in Great Britain is estimated at 2400 km2. The aim of the investigation described here is to estimate the extent of the different types of standing freshwater habitat that make up this total.
This A4 publication provides a comprehensive national rivers classification for England, Wales and Scotland based on macrophyte vegetation.
Drawing on extensive survey work, this book classifies standing waters into ten types based on their aquatic plant communities. It also discusses the trophic requirements of water plants and suggests a method for monitoring water quality using this information. This edition follows reanalysis of the data, providing revised, and in places refined, results.
Based on the water beetle recording scheme run by the Balfour-Browne Club, this report classifies British aquatic habitats in seven regions of Britain by their beetle assemblage, and ranks the recorded sites according to their conservation importance.
Considers the effects of each stage of the forestry cycle - ground preparation, tree planting through to canopy closure - in relation to their physical, chemical and biological impacts on freshwater habitats.
