Abstract: Floodplain wetlands are some of the most productive ecosystems available to aquatic and terrestrial organisms. However, regulation of lowland rivers can disrupt ecological processes occurring in the river–floodplain ecosystems, and environmental water can be delivered to affected wetlands to maintain productivity. It is not well understood at what stage following inundation there would be sufficient invertebrate biomass and large-sized individuals to support production and reproduction of secondary consumers. In this study we follow changes in the abundances of invertebrates after wetting in three mesocosm trials using soil from two wetlands from the north of the Murray–Darling Basin over 6-week periods. Peak abundances generally occurred in either the fifth or sixth weeks, but abundances were high after 2–3 weeks. Our results suggest that inundation of wetlands using environmental watering can achieve high productivity within a short time frame, within weeks. However, how quickly the high productivity is passed on to second-order consumers remains unclear and should be an area of future research.
