About the Portal

The Portal provides access to distribution data for over 3000 non-native species in GB as well as additional information such as place or origin, date of introduction and methods of introduction. For 300 species much more detailed information is provided, including information on identification, impacts and control methods.


A key function of the NNSIP project is to report on progress and monitor trends in non-native species data. Use the links below to download NNSIP reports:

The Portal was developed by a consortium of partners including the BTO and MBA and led by the Centre for Ecology and Hydrology. Distribution data are provided directly by the NBN Gateway.
