Kangaroo Conservation Boomerangs?

It is generally assumed that, because the kangaroo in Australia is a native Marsupial, it can do no harm (https://www.theguardian.com/environment/2021/feb/06/how-kangaroos-could-be-jeopardising-conservation-efforts-across-australia). Professor Mike Letnic (University of New South Wales) claims, however, that burgeoning numbers of kangaroos are threatening conservation efforts across Australia, by denuding whole areas of their vegetation. Letnic suggests that the population boom is a consequence of the culling and exclusion of wild dingoes. Dingoes, in recent times, were this Marsupials's main predator. It is certainly true that you need a balance between herbivores and their predators, inorder to maintain the health of environments.
