Derbyshire Red Data List Plant Records 1930 - 2014
The Derbyshire Vascular Plant Red Data List has been compiled using standard criteria set out by the Botanical Society for Great Britain and Ireland and was first published in 2009 (Willmot and Moyes, 2009. Derby Museum and Art Gallery). This dataset comprises all of the records for Red Data list species held by Derbyshire Wildlife Trust, the former Derby Biological Records Centre and the County Flora Recorder and covers the period 1930 a^?? 2014. In total there are 11624 records.
The data relates to the administrative county of Derbyshire and records have been collected from across the entire County. The records have been collected from SSSIs, Local Wildlife Sites and on a monad basis. Coverage across the County for the period of the dataset is considered to be very good. Many recent records will have more precise grid references obtained using hand held GPS units.
The records have been captured during site surveys for conservation purposes in relation to potential development work or improving knowledge and understanding of plant distribution and population trends in Derbyshire.
There is a high level of confidence about the accuracy of the records within this dataset. The dataset has a comprehensive geographic coverage and records have been checked by the County Flora Recorder and DWT. The dataset has been checked by the NBN Cleaner.
The dataset has been validated and maintained by Derbyshire Wildlife Trust in partnership with the County Flora Recorder Dr. Alan Willmot. The records have been generated by volunteers and professionals. Survey methods are typically walkover surveys of grid squares and/or sites, but some records are a result of detailed Phase II habitat surveys. The data has been collated over the years by Derby Museum and Art Gallery, Derbyshire Wildlife Trust and the County Flora Recorder. The data included in the dataset has been collated by DWT during 2015.
