Blue-green algae is a type of phytoplankton found in ponds and other freshwater environments and toxic species include ''Anabaena'' and ''Microcystis''. The algae arise following long spells of hot dry weather and hence bloom in the summer but are also associated with high levels of phosphate and nitrate in the water. These algae can be extremely toxic and can poison livestock, birds and sometimes dogs.
