About us

Invasive Non-Native Species (INNS) are plants and animals that live outside their native ranges, thriving in their new surroundings largely thanks to a lack of natural predators. INNS can outcompete and displace local native species (resulting in reduced biodiversity), spread disease, alter the local ecology of a habitat and some can even be hazardous to human health (such as giant hogweed). The GB Non-Native Species Secretariat estimate that INNS cost the UK economy around £1.7billion per year.

INNS Mapper has been developed to help transform our approach to controlling those INNS found in or near our freshwater, estuarine and coastal environments. The web-tool aims to provide a comprehensive map of INNS distribution throughout England which can be used to inform co-ordinated and targeted management planning for any organisations working to fight these damaging plants and animals. INNS Mapper allows users to record information on presense of INNS, indicate areas of absense of INNS and, crucially, any management being undertaken. You can easily log your sightings, investigate waterways and identify stretches that need taregting for surveying and management. Click opposite to sign in or create your log in details.
