The City & Guilds accredited Invasive Non-Native Species & Biosecurity module is suitable for anyone working in retail shops and also pond consultants and fishkeepers. It is a Foundation level course suitable for those new to the subject or who wish to improve their knowledge. You should expect to be able to complete the course in three months, or less.

This module aims to provide candidates with:

  • an introduction to the issue of invasive alien species, the ways in which they arrive in a new environment and the characteristics which could enable a non-native species to become invasive.
  • an understanding of the detrimental impacts that invasive alien species can have.
  • an understanding of how biodiversity measures can prevent/reduce the risk of introduction and spread of invasive alien species.

For the purposes of this module, we will look at the issue of invasive alien species first in relation to pets before discussing ornamental fish and ornamental aquatic plants.
