On the mainland, where it is threatened by introduced predatory species such as red foxes, cats, and dogs, it requires dense ground cover for refuge. [[Clearcutting|Clearfell logging]], agricultural development, and housing expansion have reduced their habitat, contributing to the decline of the species, as has the clearing and burning of the remaining swamplands. Moreover, quokkas usually have a litter size of one and successfully rear one young each year. Although they are constantly mating, usually one day after the young are born, the small litter size, along with the restricted space and threatening predators, contributes to the scarcity of the species on the mainland.<ref name=Reproduction>{{cite web |last=Nocon |first=Wojtek |title=Sentonix Brachyurus |work=Quokka |publisher=University of Michigan |url=http://animaldiversity.ummz.umich.edu/accounts/Setonix_brachyurus/ |access-date=30 September 2013}}</ref> An estimated 4,000 quokkas live on the mainland, with nearly all mainland populations being groups of fewer than 50, although one declining group of over 700 occurs in the southern forest between [[Nannup]] and [[Denmark, Western Australia|Denmark]].<ref name=rp>{{cite web|last1=de Tores|first1=Paul |last2=Williams |first2=Richard |last3=Podesta |first3=Mia|last4=Pryde|first4=Jill|title=Quokka (Setonix brachyurus) Recovery Plan |url=http://www.environment.gov.au/system/files/resources/4581df81-0041-4fc9-ba1b-aca7cb22246d/files/quokka-recovery-plan.pdf |publisher=Department of Environment and Conservation, Government of Western Australia|access-date=3 May 2017 |location=Bentley, WA |date=January 2013}}</ref><ref>{{cite web|last1=Bain|first1=Karlene|title=The ecology of the quokka (Setonix brachyurus)in the southern forests of Western Australia |url=http://research-repository.uwa.edu.au/files/9623707/THESIS_DOCTOR_OF_PHILOSOPHY_BAIN_Karlene_Tracy_10258658_2016.PDF |website=University of Western Australia |publisher=School of Animal Biology|access-date=3 May 2017|location=Crawley, WA|date=June 2015}}</ref> In 2015, an extensive bushfire near [[Northcliffe, Western Australia|Northcliffe]] nearly eradicated one of the local mainland populations, with an estimated 90% of the 500 quokkas dying.<ref>[http://www.abc.net.au/news/2016-09-06/northcliffe-quokka-population-decimated-after-2015-bushfire/7818884 Mainland quokka population decimated after 2015 bushfire near Northcliffe - ABC News (Australian Broadcasting Corporation)].

The population on smaller Bald Island, where the quokka has no predators, is 600–1,000. At the end of summer and into autumn, a seasonal decline of quokkas occurs on Rottnest Island, where loss of vegetation and reduction of available surface water can lead to starvation. This species saw the most significant decline from 1930 to the 1990s, when their distribution was reduced by over half (de Tores et al., 2007). The quokka markedly declined in its abundance and distribution in the early 1930s, and this tendency has continued till today. Their presence on the mainland has declined to such an extent that they are only found in small groups in bushland surrounding Perth.
