QUOKKA WATCH

Famous for their selfie game, quokkas person fans each complete nan globe including Roger Federer and Margot Robbie.

They whitethorn person little to grin astir than you assume.

Listed arsenic vulnerable by nan Australian government, these beloved marsupials look ongoing threats including ambiance alteration and deforestation.

So really are their populations faring and what tin we do to thief them?

NOT JUST ISLANDERS

Quokkas were widespread passim WA’s southwest earlier European settlement.

The preamble of foxes and feral cats, and onshore clearing, decimated their numbers.

As good arsenic nan celebrated Rottnest Island population, quokkas unrecorded connected Bald Island disconnected nan seashore of Albany.

They’re besides recovered successful 2 authorities parks connected nan mainland. Known arsenic nan Northern and Southern Jarrah Forest populations, these groups are nan astir susceptible to extinction.

IT’S COMPLICATED

Unlike different at-risk animals, quokkas person small problem pinch breeding.

Although they don’t mate consistently pinch 1 partner – preferring to support things casual – female quokkas tin commencement 1 joey a year.

When nan joey is calved – usually betwixt March and April – it makes its measurement into its mother’s pouch, wherever it continues to turn for astir six months.

We spot them statesman to task retired into nan world astir September.

The number of joeys calved each twelvemonth and really galore past to adolescence, mostly depends connected nan resources disposable to Mumma Quokka. If she isn’t eating enough, nan gestation is little viable.

Quokkas return a much casual attack to motherhood too. If a mother quokka is short connected nutrients, her baby’s proviso is reduced first.

This intends it’s captious for quokkas to unrecorded successful resource-rich environments.

Climate alteration and deforestation frighten nan magnitude of nutrient disposable to quokka populations.

FUTURE PLANNING

It’s not each punishment and gloom for nan quokka.

The WA Department of Biodiversity, Conservation, and Attractions (DBCA) has a Quokka Recovery Plan.

This scheme intends to support nan quokkas’ distribution and numbers complete a 10-year period.

Although nan astir caller scheme expired successful 2023, it remains successful spot for an further 5 years. 

An updated scheme is expected to beryllium finalised and released to nan nationalist successful nan adjacent 4 years.

CONSERVATION

Nicole Willers is simply a DBCA ecologist and Project Officer.

Quokka conservation includes investigation connected nan threats they face, education, and monitoring cardinal populations, she says.

Monitoring quokkas successful their earthy residence assesses their consequence to biology changes. It determines which changes person impacted their organization growth.

For example, signaling really a organization changes aft fox baiting aliases a bushfire tin pinpoint nan astir pressing challenges.

In nan past decade, nan astir noticeable alteration has been nan accrued effect of ambiance change, Nicole says.

PLANT-EATERS

As herbivores, quokkas trust connected plants for food.

Resources will beryllium harder to travel by arsenic nan climate becomes warmer and drier.

Nicole says smaller areas of wood intends smaller quokka populations.

“We’re seeing contraction successful nan existent vegetation done those riparian areas,” says Nicole.

“That’s going to person a beardown effect connected nan numbers of animals that tin beryllium supported successful those areas.”

CUTE GENES!

One of nan biggest challenges of maintaining quokka numbers is that they can’t past successful unfastened forest. They request circumstantial habitat, dissimilar kangaroos which are much adaptable.

The 3 abstracted quokka populations person familial differences. This is owed to nan different environments and challenges successful their unsocial habitats complete time.

“It does item arsenic good nan request to sphere nan habitat,” says Nicole.

“You want to really sphere those genetics. […There’s a] request to conserve them and negociate them well, wherever they occur.”
