Editing Overgrazing (section)

===Australia===
In many arid zones in [[Australia]], overgrazing by sheep and cattle during the 19th century, as [[pastoralism]] was introduced by European settlers, caused many long-lived species of trees and shrubs to give way to short-lived [[annual plant]]s and [[weed]] species. Introduced [[Rabbits in Australia|feral rabbits]], [[Cats in Australia|cats]] and [[Red foxes in Australia|foxes]] exacerbated the threat to both [[flora and fauna]]. Many bird species have become extinct or endangered, and many of the medium-sized desert mammals are now completely extinct or only exist on a few [[islands of Australia]].<ref name=emr2016>{{cite web | title=Arid Recovery – Roxby Downs, South Australia | website=EMR Project Summaries | date=15 March 2016 | url=https://site.emrprojectsummaries.org/2016/03/15/arid-recovery-roxby-downs-south-australia/ | access-date=27 October 2020}}</ref>

Overgrazing can also occur with native species. In the [[Australian Capital Territory]], the local government in 2013 authorised a [[Culling|cull]] of 1455 [[Eastern grey kangaroo|kangaroos]] due to overgrazing.<ref>{{Cite web|date=2013-07-10|title=ACT Territory and Municipal Services Directorate {{!}} Media Releases Kangaroo conservation cull to go ahead|url=https://www.cmtedd.act.gov.au/open_government/inform/act_government_media_releases/tamsd/2013/july/kangaroo-conservation-cull-to-go-ahead|url-status=live|archive-url=https://webarchive.nla.gov.au/awa/20200702004610/http://pandora.nla.gov.au/pan/144647/20200702-0411/www.cmtedd.act.gov.au/open_government/inform/act_government_media_releases/tamsd/2013/july/kangaroo-conservation-cull-to-go-ahead.html|archive-date=2020-07-02|access-date=2021-06-12|website=ACT Territory and Municipal Services Directorate|publisher=[[Government of the Australian Capital Territory]]}}{{cbignore|bot=medic}}</ref> [[Maisie Carr]] (1912-1988), Ecologist and Botanist, undertook significant research and studies in overgrazing and established consequences on the surrounding land in Australia.
