The Wandle Invasive Species Project is part of the Living Wandle Landscape Partnership, a Heritage Lottery Funded scheme all about reconnecting the local community with the River Wandle.

The INNS Project aimed to coordinate a single approach to tackling all invasive non-native species (INNS) within the Wandle corridor by delivering the Invasive Species Action Plan published in 2012 by the Wandle Landscape and Biodiversity Group.

This INNS Action Plan was updated as part of this project in a new, easy to use format. The plan has been presented at key meetings and workshops on the Wandle and as a result, has the buy in from all stakeholders.

The plan is available for everyone to download and use. If you have any comments or questions about the plan, please contact us by emailing INNS@wandletrust.org
