This seems to be an acceptable action on areas of original grass plains
where scrub has invaded. Invasions of scrub and the shading of loose soils,
preventing the growth of native grasses, which are deep rooted, would result
in erosian with heavy rains. Grass plains are part of the natural ecosystem
just as are woodlands and are vital for many birds. This is where local
knowledge and long term vision is necessary. We too easily forget that
outback Australia is not what it was 200 years ago. Changes have been
happening for all of that time. We need to know what those changes have been
before correct and lasting decisions are made.
