DBRC Triturus cristatus records 1970 - 2015
This dataset comprises all of the great crested newt records held by Derbyshire Wildlife Trust and the former Derby Biological Records Centre and covers the period 1970 a^?? 2015.
The data relates to the administrative county of Derbyshire and records have been collected from across the entire County. Records are not collected systematically, but reflect areas of survey activity influenced by development pressure, monitoring of key sites and the work of individuals. The records are mainly site based, and most have six figure grid references.
The records have been captured during site surveys for conservation purposes in relation to potential development work or improving knowledge and understanding of great crested newt 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 (but survey effort has not been equal in all areas) and records have been checked by the County Amphibian Recorder and DWT. The dataset has been checked by the NBN Record Cleaner.
The dataset has been validated and maintained by Derbyshire Amphibian Recorder Chris Monk in partnership with Derbyshire Wildlife Trust. The records have been generated by volunteers and professionals. Survey methods are variable, but usually include night visits to ponds and often include torching and bottle trapping. The data is initially stored in an Access database before being translated into the NBN format.
