The Seasonal Herbaceous Wetlands (Freshwater) of the Temperate Lowland Plains ecological community are temporary freshwater wetlands that are inundated on a seasonal basis, typically filling after winter-spring rains, and then drying out. It occurs in Victoria, south-eastern South Australia and southern New South Wales.

The main potential threat to the Seasonal Herbaceous Wetlands ecological community is climate change; particularly predictions of continuing decline in rainfall and shifts away from regular patterns of rainfall (Jin et al.; 2009).
A number of grassy ecological communities present on the plains also have been listed as nationally threatened; e.g Natural Temperate Grassland of the Victorian Volcanic Plain White Box Yellow Box Blakely’s Red Gum Grassy Woodland and Derived Native Grassland and Grey Box (Eucalyptus microcarpa) Grassy Woodlands Gilgai refers to surface micro relief formed by the shrinking and swelling of clays during alternate drying and wetting cycles.
