A before-and-after study in 1992 on Guam, South Pacific (Ritter & Sweet 1993), found that Mariana common moorhens Gallinula chloropus guami colonised a newly-created wetland within five months of its creation, with two adults and at least four chicks being seen. The wetland was 20-60 cm deep, 45 m long and up to 27 m wide and created using an excavator in January 1992. Spikerush Eleocharis dulcis, water lettuce Pistia stratiotesm, taro Colocasia esculenta and rusty flatsedge Cyperus odoratus were planted, although the taro died, probably because of excessive flooding.
