Allow grazing

Sheep prefer to eat some plants (e.g. the threatened Yam Daisy and Button Wrinklewort) more than other plants, so over time can totally remove some types of native plants from a native grassland site.

Native Spear-grass (Austrostipa spp.) is better able to survive livestock grazing than Kangaroo Grass (Themeda triandra), so over time livestock will reduce the amount of Kangaroo Grass in a native grassland area.

The hooves of livestock compact the soil and their trampling of vegetation can lead to erosion.

Some weeds are easily spread by the fur/wool and hooves of livestock and in their manure.

Grazing by livestock during drought when vegetation is struggling to survive leads to even more damage to native plants, soil and habitat.
