Weed management plan for grader grass
The NT Government has released a weed management plan for grader grass (Themeda quadrivalvis).
The plan sets out the requirements for grader grass management which must now be adhered to by all people.
This plan will increase awareness of the risks posed by grader grass and help with the management of the weed.

There are weed management plans for all of the following:

It is an offence not to comply with a weed management plan.

They may also:
