  1. Raise water level to restore/create brackish/salt marshes from other land uses

    A replicated, before-and-after study in the early 1990s and 2006 of two brackish marshes in southern Iraq (Al-Abbawy & Al-Mayah 2010) reported that after reflooding, the marshes contained fewer plant species than they contained before drainage. Approximately three years after reflooding, 24–27 plant species were recorded in each marsh (10–12 emergent, 12 submerged, 2–3 floating). Before drainage, 38–44 plant species were recorded in each marsh (18–19 emergent, 12–16 submerged, 8–9 floating). Methods: Monthly surveys were carried out between January 2006 and December 2007 to record plant species in Central Marsh (two sites) and East Hammar Marsh (two sites). These brackish marshes were drained in the 1990s – becoming “almost totally desiccated” by 2000, but retaining small pockets of remnant marsh vegetation. The marshes were reflooded from 2003 (details not reported). Previously published data from the same marshes, collected in the early 1990s before drainage, were used for comparison.
