Non Native Species Across Wales (1989 to 2012)
Natural Resources Wales
Description
This dataset contains species distrubution for non native species across Wales. Any non-native species present in a sample were recorded when they were 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 monitoring sites. At the time of surveying between 1970s and 2012, non-native species did not have a specific monitoring programme. Formally known as AfA 226.
Geographic Description
Wales.
Purpose
The aim of this data capture was to monitor the distribution of non-native species across Wales.
Data quality
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.
Methods
This dataset was created during species monitoring surveys. The primary purpose of this data capture was to monitor the distribution of aquatic and riparian species. Whilst these surveys were conducted the location and date of surveys which included non-native species was also recorded making up this non native species dataset.
