A replicated study in 1993-1995 at 17 UK lowland grassland sites (12 with winter flooding introduced in the previous 1-14 years) (Ausden et al. 2001) found that unflooded pastures contained high biomass of soil macroinvertebrates (mainly cranefly (Tipulidae) larvae and earthworms (Lumbricidae)) of importance to breeding wading birds. Conversely, grasslands with a long history of winter flooding had a much lower soil macroinvertebrate biomass, comprising mainly a few semi-aquatic earthworm species.
