Cymbopogon nardus,a grass weed in the rangelands of Uganda:impact on plant species biodiversity and livestock performance

摘要：

Introduction Cymbopogon nardus is a dreaded and undesirable (Marshall et al.1969) noxious grass of south-western Uganda rangelands.The species has replaced the indigenous grass species of the area notably Hyparrhenia spp.and is spreading fast to other areas.It is a tussock grass that establishes naturally from seed with leaves that contain aromatic oils,which impart a bitter taste.The species has leaves that have a rough texture.It grows fast and builds up thick coarse vegetation difficult to traverse by both humans and cattle.The canopy of a well grown plant can cover an area of up to 2m in diameter.
