Rufous hare-wallaby

Lagorchestes hirsutus

Blamed on cats

IUCN status: Vulnerable

EPBC Predator Threat Rating: Moderate

IUCN claim: “On the mainland, predation by introduced feral Cat and Red Foxes was the major cause of extinction in the wild”

Studies in support

Cats were predators, or the main predators, of reintroduced, predator-inexperienced, hare-wallabies in two locations (Gibson et al. 1994; Hardman & Moro 2006; Hardman et al. 2016). Cats can hunt locally-born wallabies (Paltridge et al. 1997). Hare-wallabies were last confirmed in southwest Australia, the Canning Stock Route and the Tanami Desert 6-66, 40-51 and 101-121 years after cats arrived, respectively (Wallach and Lundgren 2025).

Studies not in support

Lundie-Jenkins et al. (1993) found no spatial correlation one year, and a positive correlation another year, between cats and hare-wallabies. Cats breached the enclosures of two semi-captive hare-wallaby colonies, none were hunted in 5-8 weeks (from Moseby et al. 2015). Hare-wallabies were last confirmed in one WA record 30 years before, to 30 years after, cats arrived (Wallach and Lundgren 2025).

Is the threat claim evidence-based?

No studies were found evidencing a negative association between cats and rufous hare-wallaby populations. The fate of reintroduced animals is not a reliable proxy for the fate of populations. In one region it cannot be verified that extirpation occurred after cat arrival, and in another the two species possibly co-occurred for over a century before extirpation.

Evidence linking Lagorchestes hirsutus to cats. A. Systematic review of evidence for an association between Lagorchestes hirsutus and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Lagorchestes hirsutus, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance. Gold borders indicate studies that meet qualities of scientific rigour. B. Last records of extirpated populations relative to earliest local records of cats. Error bars show minimum and maximum extinction intervals. Predator arrival records were digitized from Abbott 2008. See methods section in Wallach and Lundgren 2025 for details on evidence categories.
