Compared with short-lived plants, trees and shrubs contribute disproportionately to landscape and ecosystem stability in the arid zone because of their perennial nature and drought resistance. The introduction of exotic herbivores however, has led to the suppression of the regeneration of many trees and shrubs, threatening their long term survival. The herbivores responsible for this state of affairs include wild rabbits and a variety of domestic species, such as sheep, cattle, donkeys and goats, some of which have established feral populations.
