This report provides a broad overview of 15 energy technologies identified by JNCC, including their life cycle carbon dioxide reduction potential and their other environmental impacts.
Coastal & Estuarine
16 papers derived from a meeting of the Estuarine and Coastal Sciences Association in Penrith in April 1993, covering the geography of the Solway and Cumbrian coasts, water quality and monitoring, radioactive and heavy metal contamination, biological studies, conservation and management, and studies of the benthic marine wildlife.
This report presents the results of the statistical analysis of the enlarged dataset following the first comprehensive classification scheme for standing waters in Britain
This report assesses the significance of British Lowland Grasslands, occurring below the line of enclosure or moorland wall, within a wider European frame. There are five such priority habitats in the UK Biodiversity Action Plan and these are used as the framework for the report.
Describes the main types of biological and climatic damage to heather, including the influence of management practices, and their identification, prevention or reversal.
The British uplands have two groups of lichen species of outstanding conservation interest:
1) species of western oceanic areas and
2) species of calcareous rock at high altitudes.
The most characteristically oceanic of the communities delimited in the present study are SS E1
on siliceous rock and SL 15 on limestone. Samples from high altitude calcareous rocks were few in the present survey, but Community SS X1 from Eryri, the Ben Nevis range and Beinn Heasgarnich includes some examples. Most of the samples recorded were from treeless, grazed upland sites. A cessation of grazing in these areas would be a potential concern, likely to result in shading or engulfment of rocks by vascular plant vegetation or robust bryophytes. Recreational pressures are also known to be a potential threat in some upland habitats.
The woodland section of the National Vegetation Classification (NVC) has been widely used by many people and organisations in Great Britain (and, to a limited extent, in Northern Ireland) since it became available in 1986. As a result, there is a great deal of information concerning the occurrence of woodland types in this country. However, the data is distributed between many organisations and private individuals and, until a database was set up to collate it, was largely unavailable to inquirers. The first report on the database (Hall 1996) described the collection of records and the setting up of the spreadsheet. It also discussed the differences in the methodologies of surveys used to build the database, and when to use quadrats. Since this report was published much new information has been gathered, and preliminary maps of NVC communities and sub-communities produced. These are to be published by the Joint Nature Conservation Committee as The woodland NVC atlas for Great Britain in 1998. This interim report outlines some of the patterns that are emerging, and some of the limitations of our survey data.
