The main function of Outer Hebrides Biological Recording is to develop and maintain a database of biological records for the Outer Hebrides, including the outlying islands such as St. Kilda. As the custodians of these records, supplied by individual recorders, recording groups, research students and scientists, ecological consultants and environmental and conservation organisations, we have a responsibility to ensure that, as far as is possible, this data is accurate and is widely and freely available.

All our records, with certain restrictions for environmentally sensitive species or habitats, are made available through the National Biodiversity Network Scotland Atlas on-line database.

Descriptions of the OHBR datasets are available on the NBN Atlas website and you can view and download the records from each dataset. As we have data sharing agreements with other organisations: Botanical Society of Britain and Ireland, British Bryophyte Society and the British Lichen Society, not all the records in our database are included in our datasets, therefore for some taxa, you will have the NBN Atlas species search function. Please note that you will have to be a registered user to view or download the records. Before using data on the NBN Atlas users should be aware of the NBN Terms and Condions: Guidance for using data and the Guidance on the definition of non-commercial use.

Information held on the database is made freely available for non-profit making purposes which meet the objectives of Outer Hebrides Recording, the use of the data for commercial purposes requires permission from OHBR. We do not make a charge for the use of our data but if a request is made which requires the the extraction, analysis or collation of records from the main database by commercial organisations and consultants there is a fee to cover the time required. Anyone using OHBR data from any source will also need to comply with OHBR Terms and Conditions
