Site types that use this protocol

The crustacean zooplankton which dominate the open water of lakes form an important link in the food chain between phytoplankton and fish.  Most lakes contain a few species from a small number of genera but marked changes in species composition can occur when there is a progressive change in the trophic status.

Species presence and abundance are determined through fortnightly sampling at lake sites only.

During the winter months we make fewer measurements but there are still weekly visits to sites to check equipment and take water samples.
