  1. Restore or create coastal and intertidal wetlands

    A before-and-after study at two sites in Essex, UK (Atkinson et al. 2004), found that the number of waders using the sites increased in the first two winters after the surrounding seawall was breached in August 1995. At one site (Tollesbury, 20 ha) the number of waders stabilised after increases in the first two winters, particularly in common redshank Tringa totanus and dunlin Calidris alpine; whilst the number of songbirds decreased after the first winter. Some species (e.g. knot Calidris canutus) did not start using the site until the third winter. At the second site (Orplands, 42 ha), the number of common redshank, dunlin and grey plover Pluvialis squatarola increased during the first winter and then the community composition changed across the site, with higher areas holding similar species to adjacent saltmarsh and lower areas being similar to mudflats.
