Restore or create coastal and intertidal wetlands
A replicated, paired study in January-March 2002 in southern California, USA (Armitage et al. 2007), found that wader diversity was higher in three out of five restored wetlands compared to on paired control (non-degraded) sites, lower on one and similar on a fifth. In addition, total density was as high or higher in four restored sites (although responses varied between species) and behaviour was similar across restored and controlled sites, with over 85% of three of the four species groups observed feeding. Densities of willets Catoptrophorus semipalmatus were often higher in restored sites whereas densities of marbled godwits Limosa fedoa were often denser in control sites. The authors conclude that wetland restoration should be considered at a landscape scale because each site is beneficial for a different assemblage of species.
