Non-native species records collected during Environment Agency monitoring activities. Primarily aquatic and riparian species. This first set contains records from the BIOSYS database, representing invertebrate, plant and algal monitoring from marine and freshwater. Adhoc records and those from River Habitat Survey and Fish monitoring will be included in the next and all subsequent updates (Jan 2012 onwards). Please help us to improve our species records by reporting any errors you find within this dataset to alice.hiley@environment-agency.gov.ukPurpose
Records for non-native species, taken from routine sampling surveys and from ad hoc surveys, collatedSampling Description
Quality Control
Records collected before 1990 are ad hoc and quality is specific to the record. More recent records are checked and surveyors are trained in the identification of non-native species. We are most confident in records from 2009 onwards.Method steps
- Any non-native species present in a sample are recorded when they are of the target group, for example Signal Crayfish (Pacifastacus lenisculus) in a benthic invertebrate sample or Canadian pondweed (Elodea canadensis) in a plant survey. Other non-native species are recorded when seen at or around Environment Agency monitoring sites. Non-native species do not have a specific monitoring programme.
Taxonomic Coverages
Geographic Coverages
The records cover England and Wales. There is a bias towards rivers and other sites where the Environment Agency carries out monitoring. The coverage is fairly even. All records have 100m resolution or greater.
