Dactyloctenium aegyptium (crowfoot grass).
Abstract Producing large quantities of seeds, D. aegyptium is a pioneer grass that quickly colonizes disturbed areas with light sandy soils, often near to coasts or where water accumulates. It is a common component of weed floras throughout the tropics but is rarely reported as an aggressive weed on its own. It is not on federal or state noxious weed lists in the USA and is not recorded on the ISSG database but is recorded by PIER (2016) as invasive on a number of Pacific and American islands including French Polynesia Islands, Micronesia, the Northern Mariana Islands and Hawaii. It is also listed as invasive on islands in the Mediterranean, the USA, Mexico, Costa Rica, Puerto Rico, Virgin Islands and the Lesser Antilles (Vibrans, 2009; Florida Exotic Pest Plant Council, 2011;Chacón and Saborío, 2012; Burg et al., 2012; Rojas-Sandoval and Acevedo-Rodríguez, 2015; DAISIE, 2016; USDA-NRCS, 2016).
