Abstract
The response of grassy vegetation to exclusion from grazing was found to be related to a major productivity gradient in the central highlands of Tasmania. All sites showed a trend toward increased structural complexity, a decrease in bare ground and a decrease in species richness when grazing was excluded. However, the effect was much more pronounced at sites of high productivity. These findings support the theory that species richness is a function of both disturbance and the rate of competitive exclusion (site quality), and support suggestions that stock grazing is inappropriate above 1000 m on the Central Plateau.
