This dataset comprises validated species records with a sample/sighting date earlier than 1st January, 2000, as received and collated by Gloucestershire Centre for Environmental Records (GCER). This replaces the pre-2000 records of our previous historic dataset. The records cover all the groups recorded in the county, including vascular and lower plants, fungi and lichens, birds and animals. See the "Additional Information" section for details of records which have NOT been included. In general, public viewers may see these records as a 1km distribution map where the resolution of the original records allows. Zero abundance records are not included. Some records are only available at a lower resolution, e.g. tetrad records (2km x 2km). Unvalidated, ad hoc, "negative" (i.e. zero abundance), known doubtful and purely anecdotal records are not included. See the "Additional Information" section for details of datasets held by GCER which have NOT been included in this upload because they are already available on the NBN Gateway via another data provider. The uploaded data includes some additional attributes such as system codes. These are for use by GCER and national conservation agencies.
