Welcome to the Cumbria Biodiversity Data Centre

Species Data

The CBDC database of c. 2 million digitised records has been built up over a period of 20 years and is becoming ever more comprehensive through the focus of the CBDC team and with the help of wildlife groups in the county. CBDC working with other local and national organisations is the primary collation point for volunteer records of many taxonomic groups, including most invertebrates, mammals, amphibians, reptiles and invasive species. It also manages the species data from Tullie House Museum's Collections, much of which is Cumbrian. In addition CBDC holds copies of the largest datasets from the Cumbria Botany Group and Cumbria Bird Club, records from many nature reserve managers in the county, Cumbria Wildlife Trust's digitised data including County Wildlife Site surveys and records from other professional surveys. The county's natural history societies and other recording groups also spend a great deal of time collecting and collating records that they share with CBDC and we are most grateful to everyone involved for all their hard work. A summary of the data held and a list of the main datasets can be found below.

Additional Data Sources

This is a non-complete list of significant data sources we are aware of but don't currently hold copies of/include in our data searches. This includes records from formal organised monitoring schemes. For some research projects and major developments it will be appropriate to contact such organisations separately.

 -  The Wetland Bird Survey is the primary source of detailed bird monitoring data on wetlands, including Cumbria's significant estuaries and lakes.
 - The British Trust for Ornithology's Breeding Bird Survey and other bird surveys.
 - Walney Bird Observatory is a long-running bird ringing station on Walney island in the south-west of Cumbria and also collates all bird records on the island.
 - BSBI Cumbria Botany Group tetrad records post Flora of Cumbria (1996)
 - Cumbria Bird Club records outside main atlas recording surveys.
 - Natural England records for SSSIs are largely held in individual reports and not databased.
 - Westmorland Bat Group may hold some extra records (a project to check this is planned for winter 2015/16).
 - BCT National Bat Monitoring Programme data

Although we do hold many of the records locally, at present CBDC doesn't search the NBN Gateway so will not hold complete information from all specialist schemes and societies and organisations. It is hoped to incorporate this service into data searches in future. Please note under the terms of the Gateway you need to contact each data provider for permission to use any records from the Gateway for commerical or research purposes.

Summary of data held

As at July 2015, most records are of birds (40%) plants (22%) or lepidoptera (20%) reflecting both the popularity and knowledge of these groups amongst naturalists and intense recording activity relating to local and national atlasing projects. However data is held on a very wide range of taxa, with over 12,000 different Cumbrian species represented in the database.
