Drawdown is the habitat of exposed rock, cobbles, sand, silt and mud that occurs when the level of ponds and lakes and especially reservoirs falls during a dry summer. This habitat has its a suite of characteristic species, some of which (locally at least) are confined to that habitat, and others which occur in other habitats. Species which I only know from this habitat are Limosella aquatica, Littorella uniflora, Lythrum portula and Persicaria minor. Other characteristic species are Bidens tripartita, Chenopodium rubrum, Mentha arvenis, Persicaria amphibia, Persicaria hydropiper, Potentilla anserina and Rorippa palustris. Persicaria maculata, Senecio vulgaris and Sonchus asper are among the accessory species.
