Derbyshire & Peak District Protected Species Database (Summary of available records 1970- 2008)

Quality Control

This dataset should not be regarded as offering comprehensive coverage of the region, though much effort has been expended to compile this dataset. Ecological consultants should make contact with Derbyshire Wildlife Trust who will provide more detailed information and interpretation on behalf of the Derbyshire Biodiversity Network partnership. Absence of a record on the Gateway should not be taken as evidence of the species being absent on the ground.

Otters and Water Vole have generally been well-surveyed across the county by Derbyshire Wildlife Trust in recent years. Great Crested Newt have been well-surveyed in certain parts by C. Monk, but not in others.

Crayfish data has only been compiled from available Environment Agency data.

All Natural England?s bat roost survey reports have been comprehensively included from c.2000 onwards. Multiple species found at a single roost site are not indicated here. Older records have been included where available, but we recognise there are many records likely to be held by local bat groups that are not included. We have endeavoured to exclude all records not relating to roost sites.

NOTE: Absence of a record on the Gateway should not be taken as evidence of the species being absent on the ground. Contact the local records centre for more information.

Method steps

1. Records have been collated from many different sources, and collected for a variety of reasons.
   
   Recent Bat roost data comes from Bat Survey Report Forms submitted annually to Natural England. Older data was collated from biological records centres.
   
   Recent Water Vole, Otter and Great Crested Newt records mostly come from specific surveys by Derbyshire Wildlife Trust; older records from a range of sources.
   
   Crayfish data comes predominantly from survey work by the Environment Agency

Derbyshire and Peak District.

Note that many early bat roost records are included in this dataset from well beyond the intended recording area. They were imported en masse from various sources in an attempt to capture as many records as possible for the Derbyshire & Peak District region. It has not been feasible to delete them.

Wherever possible, records have been collected to an accuracy of 100m. Many coarse records above 1km resolution have been excluded.
