Tackling INNS

This section on tackling invasive non-native species includes good practice guidance as well as worksheets and case studies.

Our primary tool for tackling invasive non-native species is the London Invasive Species Plan.

London Invasive Species Plan

What is the London Invasive Species Plan?

The London Invasive Species Plan (LISP) has been created to provide organisations or persons interested in addressing invasive non-native species with a coherent direction and a coordinated approach. It combines current best practice with knowledge from leading species experts to provide the most appropriate management options available.

The London Invasive Species Plan also links to national strategies and local action. This co-ordinated approach increases the effectiveness and sustainability of our actions and has better cost benefits.

How can I use the LISP?

The LISP is for use by anyone involved or interested in the management of invasive non-native species within the Greater London area. It has been developed as both a standalone document and action plan, and as guidance for the creation of specific plans where required. The plan provides actions and suggests persons or organisations able to complete or facilitate each action.

Note that this plan directly links proposed actions to the LISI species of concern categories not to individual species themselves. This will allow the plan to remain current when the species list is reviewed and updated in response to the changing environment, the growth of our knowledge and the changing nature of our work.

Case Studies

Johnson Grass

Rapid response required – Johnson grass in central London

London is unique in regards to invasive non-native species as new and previously unseen species often establish first in our urban landscape. One such species, Johnson grass (Sorghum halepense), is already known as a highly invasive species in other locations throughout the world. Johnson grass has become naturalised in areas of the United States of America. It […]
