Invasion of northern Australia by Gamba Grass and other introduced grasses

Advice to the Minister for the Environment, Water, Heritage and the Arts from the Threatened Species Scientific Committee on Amendments to the List of Key Threatening Processes under the Environment Protection and Biodiversity Conservation Act 1999


Ecosystem degradation, habitat loss and species decline due to invasion of northern Australia by introduced Gamba Grass (Andropogon gayanus), Para Grass (Urochloa mutica), Olive Hymenachne (Hymenachne amplexicaulis), Mission Grass (Pennisetum polystachion) and Annual Mission Grass (Pennisetum pedicellatum).

Ministers Reasons for a Threat Abatement Plan decision. Date of decision - 06/09/2009:

The Threatened Species Scientific Committee recommended that there should be a Threat Abatement Plan for this threatening process as it is a feasible, effective and efficient way to abate the process at this time. The majority of the weeds in this threatening process are in the relatively early stages of invasion and still at a level that makes management and control possible and practical. In addition, this threatening process covers the states and territories of Queensland, Western Australia and the Northern Territory and abatement action would benefit from national coordination.
