    Protected and Invasive Species Records Collected Through Environment Agency Survey 1995 - 2021

    Published by Environment Agency

    Description

    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.ukThe 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.

    Purpose

    Species records are captured by the Environment Agency for many purposes; from monitoring water quality and fish populations, to investigating opportunities for creating biodiverse habitat.

    Geographic scope

    Description

    The records cover England. There is a bias towards rivers as this is where the Environment Agency carries out routine monitoring. Wetland sites are also targeted to give cover to areas where we are most likely to have an impact.

    Latitude
    From 49.989 to 55.788
    Longitude
    From -5.711 to 1.763

    Methodology

    Quality control

    Our confidence is High. Each record has been provided either as part of a survey where the surveyor was professional, trained or validated by Biodiversity staff.

    Method steps
    1. Records are collected by a variety of methods; these include targeted survey for particular species, standardised sampling methods for many species, sightings made during field work. There are many records collected in partnership and in general our partners incorporate jointly owned records into their datasets and load them to NBN Atlas.
