Microcrustacea were collected in four streams, with contrasting pH, of the Ashdown Forest, southeast England. Samples were taken over four seasons. Comparison of the cladoceran communities with those of rivers in the London area showed similarities in species richness and composition. Persistence in the microcrustacean communities of the four streams exhibited a different pattern from that found in the macroinvertebrate communities. Clear differences in the abundance of mircocrustacean groups were observed between streams with cyclopoid copepods domination harpacticoid copepods in the two acid streams. Many microcrustacean groups and species had a distinct seasonality and for some the timing of density maxima also varied between streams.
