SURVEYS AND PUBLICLY AVAILABLE DATA
10.1 Environment Agency biological survey data
The Environment Agency holds its biological data in an Oracle database known as Biosys, and holds its fish data on the
National Fish Population Database.
The data can be accessed from the Ecology and Fish Data Explorer https://environment.data.gov.uk/ecology/explorer (145)
This holds data from fish, diatom, macrophyte and macroinvertebrate samples. A user guide is embedded in the system.
All the data can be downloaded in one request as a bulk download, but a system with sufficient capacity will be needed.
Alternatively, a sub-set of data can be selected by drawing a polygon on the map interface to define the area of interest.
The map will show the survey sites within it for the different types of biota (Figure 6.13). A description of the data that is
available for a specific site can be seen by clicking on its dot on the map.
