A small before-and-after on Chatham Island, New Zealand between 2001 and 2004 (Moore & Davies 2004) found that three pairs of Chatham Island oystercatchers Haematopus chathamensis at two beach sites (each approximately 100 m long and 40 m wide) nested higher up the beach and further from the storm tide zone (thus reducing the chances of nests being washed away) following the removal of invasive marram grass Ammophila arenaria through the application of broadscale (Roundup™ – glyphosate) and grass-specific (Gallant™) herbicides and physical removal. The impact on nesting success or productivity was not reported.
