Method steps

1. 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.

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.
