Climate change has underlined the importance of monitoring freshwater ecosystems. This course is designed to help professional surveyors and amateur naturalists increase their understanding of the large and diverse group of invertebrates that inhabit our rivers and ponds. Illustrated talks and field excursions will demonstrate the latest practice in sampling methodology and preservation of specimens. Identification sessions will cater for both amateur and professional interests and needs.

Discussion of aquatic ecology and the life cycles of individual species will help develop an overview of freshwater ecosystems.

Samples collected on field trips, together with preserved specimens, will form the basis of laboratory workshops to develop identification strategies and improve your confidence in using keys to a level appropriate to your own needs, be this to family or species. You will be able to use a full range of published keys whilst course notes and copies of some unpublished keys will be provided for you to keep and use in any future monitoring work.

The field trips and lab sessions will enable you to build up species lists for the sites you visit. At the end of the course you will be shown how to use this data to calculate several biological indices which can be used to measure the conservation value of a freshwater site, prior to developing management strategies. You will also be given, and shown how to use, a copy of SAFIS, the analysis software written by the tutor. For any future survey work this will automatically calculate the relevant simply by typing in a species list. The software also provides distribution and habitat information and can help indicate incorrect identifications.

This course is eligible for the Suffolk Recording 2020 bursary. Please contact the centre directly to apply.

Before You Attend

What to Bring

  • Although all collecting equipment is provided many students prefer to bring personal items, such as a 10x or 20x hand lens for field use, a pencil and notebook.
  • For field work wellington boots will be needed to work in the water.
  • Health and safety equipment will be available from the Centre but you may wish to bring a personal pair of household rubber gloves and a bottle of alcohol based hand gel.
  • Further health and safety information is available before the course on the tutor’s own website (see below).
  • During the course you will collect and identify specimens and so it is well worth bringing tubes or other suitable containers in which to keep your own preserved, labelled vouchers.
  • In order to take away electronic copies of unpublished keys, course notes and software as well as a large collection of papers and other information you will need to bring a memory stick for download.

Recommended Reading

There are too many keys dealing with species level identification of the various invertebrate groups to list here. The books below are broader in scope and hence more relevant to the beginner. The first three are particularly recommended in order to get to grips with family level identification of a wide range of freshwater invertebrates and far more accurate than general naturalists’ guides.

Freshwater Biological Association Publications www.fba.org.uk

S Pawley, M Dobson & M Fletcher - SP 67 A Guide to British Freshwater Macroinvertebrates for Biotic Assessment

M. Dobson, S. Pawley, M. Fletcher & A. Powell - SP 68 Guide to Freshwater Invertebrates

Field Studies Council http://www.field-studies-council.org/

PS Croft - A Key to the Major Groups of British Freshwater Invertebrates

The two FBA keys are up to date and either are highly recommended with SP68 being the more comprehensive of the two. Croft was published in 1986 but is still very useful and less expensive. The following is out of print but is good preliminary reading and can often be found secondhand:
