Please follow the Govenrment's latest advice and rules with regard to coronavirus. You can undertake some of the activities listed below from your home, e.g. online learning, downloading the app, but other activities will be on hold for now.

Shropshire Wildlife Trust have recently been awarded a Water Environment Grant by Natural England, funded through the European Agricultural Fund for Rural Development and by Defra, for 2020-2021. This project aims to bring together a Local Action Group for Shropshire, for all non-native invasive species. In addition, we will be controlling Himalayan balsam in a few key areas (sites to be confirmed) using novel bio-control methods. The GB Invasive Non-Native Speceis strategy and Midlands Regional Invasive Species Management Plan will help guide this work:

Check back here for updates on local activities, and how you can get involved. Meanwhile, please see the links and information below:

Non-native invasive species can be found in many of our rivers, ponds, canals, and other freshwater bodies. These species can be a threat to our native wildlife by bringing in diseases, out-competing them for food and light, and even eating our native species!  This page has a selection of images showing some of the species you may come across. The GB Non-Native Species Secretariat website has a wealth of information, and can be found here:

There are various ways of tackling these species, and you may be able to get involved with a volunteer group near you. If you believe you have non-native invasive species on your land, you can find out the best course of action here:

You can help in many ways, including recording any non-native invasive species you see via the INNS Mapper (free resgistration): , or one of these recording schemes:

An excellent way to learn more is to undertake the free e-learning modules on the GB Non-Native Species Secretariat website here:  and the Biosecurity online training from the University of Leeds:
