Lakes - Phytoplankton

Phytoplankton form the base of many food webs in lakes. This method uses the principle that an increase in nutrients (particularly phosphorus) leads to an increase in phytoplankton biomass and a change in the taxonomic composition, often leading to an increased occurrence of cyanobacteria (blue-green algae).

The method statement published in 2009 for the first river basin planning cycle, and its associated summary, have now been updated for the second cycle, linked below.

NB Please note the erratum in the method statement with regards to equation 5 on page 12; this corrects the missing 3 decimal places (added December 2014).
