Grader Grass was one of those weeds that crept in while no-one was looking. Deliberately introduced from India as a potential pasture grass but possibly never intentionally released, it was first recorded in the wild in Queenslands' Mackay district before the Second World War.

If a plant is to become a weed once it has been introduced, it must be able to complete its life cycle and spread in its
new range. A weed’s life cycle can be analysed in terms of life stages that are linked by key processes. While it is possible to draw general pictures of the life cycles of many weeds of the Burdekin Rangelands, comprehensive quantitative information is available for relatively few.

There are many environmental problems with introduced grasses in northern Australia;
altered fire regimes which in turn damage our native vegetation is just one of them. However,
improved pastures are an important part of cattle production for many markets.
