Identifying and Managing Non-native Invasive Plant Species


This training course delivered by Chris Toop MCIEEM will commence with an introduction detailing what non-native, invasive and invasive non-native species are and why they may be a problem, then move onto legislation listing INNS and the control of INNS across the British Isles.

The course will focus on 10 ‘common’ species, including the ‘big three’ (Giant Hogweed, Himalayan/Indian Balsam and Japanese Knotweed), aquatics (Azolla, Crassula and the Elodeas) and others, including Cotoneasters, Japanese Rose, Montbretia and Rhododendron.

For each taxa the course will discuss their ecology and dispersal, survey techniques, sources of up-to-date information, reporting and devising mitigation measures.

Finally the course will examine where to find out about control measures, proposing on-site mitigation, writing and implementing management plans, and associated control measures on active sites.

Knowledge Level


Prior Knowledge

Although a botanical background will not be necessary, a basic grasp of plant biology (e.g. annual v perennial) and environmental legislation would be helpful.

Learning Outcomes

  • Know the relevant legislation relating to control of non-native invasive plant species.
  • Be able to identify some of the most common INNS plant species.
  • Understand how INNS plants spread and their impact.
  • Understand what actions an ecologist should take on site to minimise risk of spread.
  • Know the correct reporting protocols and sources of up-to-date information.
  • Understand when and how to apply/organise controls.
  • Management techniques for INNS pre-construction, during works and post-construction.
