Invertebrate Site Register - England 1738-2005

Quality Control

There are known errors in grid references in some records entered in earlier versions of the Recorder program usually as a result inclusion of incorrect 100km square. These are being corrected as they are found. Identifications have had varying level of expert verification applied, with some records removed as a result. Some data are unchecked. Paper copies of most of the original data are held at the Biological Records Centre, C.E.H. Monks Wood where they can be consulted by prior appointment. Data coverage for individual species should not be considered to give a comprehensive description of occurrence.

Method steps

1. Data have been gathered systematically from national and local entomological, other invertebrate and other natural history journals, the paper data files of the regional offices of the country conservation agencies and utilities, local record centres, national recording schemes, museum collections, county wildlife trusts, research establishments etc, and the notes, collections and experience of amateur and professional entomologists and naturalists.

The original ISR covered the whole of England, Scotland, Wales and the Isle of Man. This part of the dataset covers England only. Data on Scotland and Wales may be accessible through Scottish Natural Heritage and the Countryside Council for Wales.
