Invasive non-native species (INNS) can be easily transferred between sites around on clothing, footwear, vehicles and equipment. Those working in the field have a responsibility to minimise their risk of spreading INNS. Use these materials to learn more or teach others about non-native species, how to identify them, and how to prevent their spread:


Take the e-learning to learn about non-native species. Available modules include:

  • an introduction to non-native species
  • identification and recording
  • identification of key freshwater plants
  • identification of key freshwater invertebrates
  • identification of key riparian plants
  • biosecurity
Identification and recording

Find out more about non-native species using the Non-native Species Information Portal

Find out how to identify more species by downloading Identification Guides which can be carried with you when working in the field

Scottish Natural Heritage have developed a booklet: Invasive non-native plants associated with fresh waters - a guide to their identification
