Biodiversity data for decision making indicator
E1a. Cumulative number of records
E1b. Number of publicly accessible records at 1km2 resolution or better
Type: State Indicator
Good policy making and evaluation is based on evidence. Millions of biological observations (records) have been recorded in the UK over the past century by a wide variety of organisations and individuals. This indicator provides an evaluation of the number of records added to the National Biodiversity Network (NBN) Atlas which replaced the NBN Gateway, in a particular year, and the resolution of those data, as a proxy for the evidence available to underpin conservation decision making.
The number of records within the National Biodiversity Network Gateway has increased from 15 million at the start of 2004 to 68.7 million at the start of 2012, and to 131.3 million at the end of March 2017, at which time the Gateway closed and was replaced by the NBN Atlas. Since the start of the NBN Atlas in April 2017 there has been an increase of 81.9 million records to the end of May 2018.
The number of publicly accessible records which are at 1km2 resolution or better increased from 10.5 million at the start of January 2010, to 35.2 million at the end of March 2017 in the National Biodiversity Network Gateway. The NBN Atlas which started in April 2017 has 126.9 million records at the end of May 2018 which are at 1km2 resolution or better.
