This day course will involve using a range of techniques to survey for and collect a variety of freshwater habitats for aquatic invertebrates and identify to the family level where appropriate.

The collected material will help build a species list for the site and provide data for future site management plans.

Tutors in freshwater ecology and identification will lead the day, and participants can learn about freshwater sampling methodologies. It is an opportunity to survey a range of different invertebrate groups.

All records collected will be added to existing site records and shared with the Local Environmental Record Centre and relevant national recording schemes.

This course is aimed at adults only and must be at least 18 years old to attend.

What will the day involve?

  • You will learn about the distinct types of water bodies.
  • Practical experience using the methodology to survey and sample aquatic invertebrates.
  • Practical experience in the identification of the major aquatic groups.
  • A chance to meet fellow like-minded people from a range of different disciplines
  • Access to field equipment with support and guidance from tutors.


This course takes place at Doddington Hall.

Tutor: Graham Warnes

Graham Warnes began the collection and analysis of data relating to freshwater invertebrates as a citizen scientist, typically as part of a collaborative project with professional scientists within the Environment Agency (EA) and received years of extensive mentoring in freshwater invertebrate taxonomy, community response to stressors, and the assessment of conservation values from the late former director of the Freshwater Biological Association, Richard Chadd.

Graham has contributed to several wildlife conservation projects and has a working knowledge of non-native Gammaridae.
