The NNSS e-learning provides an introduction to non-native and invasive non-native species, and guidance on identification, reporting and biosecurity. The e-learning is designed for use by anyone working in the field or with an interest in this area, such as government field staff, volunteers, and recreational water users.


Module 1. Introduction to invasive non-native species

Module 1 offers a basic introduction to invasive non-native species, covering: 

  • why they are an issue
  • what they are, and how many there are in Britain
  • what impacts they have
  • how they are introduced and spread
  • how we respond to them

Module 2. Identification and recording

Module 2 consists of four topics covering identification and recording of non-native species:

  • why recording is important
  • what to include in a record
  • where to send records
  • identification of freshwater plants
  • identification of freshwater invertebrates
  • identification of riparian plants

Module 3. Biosecurity

Module 3 explains the importance of following good biosecurity when working in the field, and provides guidance on how everyone can reduce their risk of spreading invasive non-native species. Find out more about:

  • why biosecurity is important
  • how non-native species are spread
  • planning for biosecurity
  • practising biosecurity in the field: Check Clean Dry
Biosecurity for University field staff

The University of Leeds have developed a version of Module 3 for anyone carrying out field work as part of their research.
