Description

This Weed Management Plan forms part of a strategic approach to gamba grass (Andropogon gayanus) management in the NT, with the overall aim being to mitigate the damage caused by gamba grass in relation to the natural environment, property and infrastructure and public health. A comprehensive weed risk management assessment found gamba grass to be a very high risk weed where potential exists for successful management.

Weed Management Plan for Andropogon gayanus (Gamba Grass) 3 1. Introduction 1.1 Background Gamba grass (Andropogon gayanus) is a tall African perennial grass first introduced into Australia in the 1930s. Preliminary trials on the species were conducted at the Katherine Research Station from 1946. Gamba grass in northern Australia is a cultivar, known as cv. Kent. It was developed specifically for use as a cattle fodder in the NT by crossing two varieties and has been widely planted in the pastoral and agricultural areas of the Top End. Since that time gamba grass has proved to be highly invasive with the ability to negatively impact savanna landscapes when it is not adequately managed. Where gamba grass continues to be used as a fodder, it requires careful management to maximise productivity, limit seed production and control spread. Eradication of isolated plants is relatively straightforward, however once gamba grass establishes, it requires a higher level of investment to contain or eradicate. Spread prevention is the most successful and cost effective way of managing weeds. Gamba grass seed can be spread via wind, water, livestock and other animals (e.g. feral pigs) and machinery contaminated with seed. It can also be spread if fill, gravel or hay contains seeds. More information on gamba grass, including its biology, ecology and history is available in the document Gamba Grass in the NT: A Summary of Current Knowledge which is available at www.nt.gov.au/gamba. 1.2 Period and application of plan This plan, being the Weed Management Plan for Andropogon gayanus (Gamba Grass), has been approved under section 10 of the Weeds Management Act (the Act). This plan applies to the whole of the NT and specifies the minimum requirements for managing gamba grass in the NT. It applies to all landholders, including the Northern Territory Government. The plan takes effect from the 21 day of July 2010. It must be reviewed within three years of this date and will cease ten years from this date, unless replaced by a revised plan. During the first three years of this plan, the NT Government will monitor the effectiveness of the plan to determine the most appropriate management obligations of landholders for future planning and control. In the meantime, the requirements specified should be observed by all landholders. Meeting the objectives set out in this plan is important for long term effective management of gamba grass in the NT. Landholders are required to meet the management requirements outlined in the plan in order to secure compliance with the Act. Penalties apply for non-compliance. 1.3 Coordinated and adaptive management of gamba grass This Weed Management Plan has been developed with extensive stakeholder consultation. It aims to address the concerns of all stakeholders by providing strategic management directives which are intended to mitigate the economic and environmental risks posed by gamba grass, while addressing the desire for continued use of some existing gamba grass pasture in the B/C zone. The Department of Natural Resources, Environment, The Arts and Sport (NRETAS) will work closely with stakeholders, including other government departments, to implement and monitor the performance of the plan. Continued improvement will be made possible through a commitment to regularly review the plan and make changes where necessary. In particular, it is recognised that the initial three year period of implementation will be extremely important with respect to informing and supporting landholders and managers and gauging the costs and effectiveness of actions taken pursuant to the plan.
