Protected land, including national parks, are a cornerstone of conservation. Once an area is legally protected, it is tempting to assume that it is shielded from further degradation.
However, our research, published in the journal Global Ecology and Conservation, has found Australia’s national parks are under serious threat of overgrazing. Significantly, native kangaroos are major contributors to the problem.
In some places we looked at, the effect of overgrazing in protected areas was just as pronounced as on private land with no legal protection at all.
In the public debate over culling and otherwise managing kangaroo populations, attention is typically divided between their economic impact on people versus welfare concerns. But there’s a third unwilling participant in this dilemma: the thousands of other native species affected when native grazer populations grow out of control. MORE
