Protected species and invasive species records collected through Environment Agency survey, including from; BIOSYS database - invertebrate, plant and algal monitoring from marine and freshwater, the National Fish Population Database - fish monitoring, and ad-hoc records from surveys at local offices. Currently not including records for fresh water pearl mussel. Please help us to improve our species records by reporting any errors you find within this dataset to marina.flamank@environment-agency.gov.uk The invasive records are a subset of those we collect, ones with greatest impact to our work. In future we hope to include all invasive species records we collect.
