KoalaTracker's frequently asked questions...

Koalas need to conserve as much energy as possible, as the energy value of their diet is low.  Koalas generally sleep for about 16 to 18 hours a day. A common misconception is that they are “stoned” after eating the eucalypt leaf.  This is not so.

This is a myth that we are particularly keen to de-bunk.  Recent research carried out by the Australian Wildlife Hospital in Queensland, which includes 5 separate radio-telemetry studies on translocated koalas, concluded that koalas do not die as a result of translocation and disperse and establish home ranges in a manner that suggests that there is little competition for space with resident koalas. The important point to underline though is that the translocation needs to be conducted by koala experts. 

Disease in koalas may not be apparent to the casual observer, unless the physical signs are overt.  For example, a brown, dirty tail will point to cystitus and sore, red, weapy eyes will point to conjunctivitis (both are symptoms of Chlamydiosis in koalas).   

Unusual behaviour, such as sitting on the ground, not moving when approached, would warrant the koala being reported to wildlife rescuers for an urgent health assessment. 

This website was the brainchild of Alex Harris (owner of Digital Publishing Australia). In 2009, Alex created the website and conceived of the mapping and analysis project, and co-founded the organisation, Koala Diaries, which this website previously served, with Noosa koala carer Carolyn Beaton. 

Alex bore the full expense of site development and pays for hosting, and has to-date donated more than 1,000 hours to ensure the smooth functioning and constant improvement of this koala mapping website, now known as www.Koalatracker.com.au. 

Habitat loss and fragmentation through urbanisation and resulting impacts - such as car strikes and dog attacks - are the most common causes of koala deaths.  Disease is also a key threatening process, and underestimated in magnitude. You can search (from the member page) on cause of death and injury, or for a listing of koala sightings in your own area, or view the map, to see what is impacting koalas where you live.

The two significant conditions of which we some knowledge are the Koala Retrovirus [KoRV] infection and Chlamydiosis.  The constellation of diseases caused (or suspected to be caused) by these infectious agents are a critical threatening process, and are undoubtedly hastening extinction in isolated koala populations.

The koala lives almost entirely on eucalypt leaves but sometimes some non-eucalypt species (such as Acacia and Melaleuca).   The koala will demonstrate preferences for particular varieties of eucalypt and these vary from one region to another.

Interestingly, there is a theory that the eucalypt diet is an evolutionary adaptation that takes advantage of an otherwise unfilled ecological niche, since eucalypt leaves are low in protein, high in indigestible substances, and contain compounds that are toxic to most species.  To digest the harsh leaves, the koala has developed a special intestinal chamber called the caecum.  This may be as long as 2 m, and contains bacteria which ferment the leaves and help make them more digestible.

See the KoalaTracker Links page for resources on what trees koalas eat in various areas. It is not true that koalas don't drink water, as many photos on this site from members of the KoalaTracker community show. See photos of koalas drinking water.

About KoalaTracker

Each marker on KoalaTracker's koala map represents the individual mapping of a koala by a member, transforming the concept of Koala habitat from a bunch of pixels on a satellite map, to the actual location of koalas. 

It is this that enables meaningful and effective action to save the koala.

It is self-funded by its creator Alex Harris, supplemented by donations. Please support this free resource.

Find Koalas

koala map 05

About 50% of forests and woodlands within the historic range of koalas throughout Australia has been cleared for agriculture and urban development since 1788. Most of what was lush koala forest is now housing estates.

While many people have never seen a koala in the wild, they might just be traversing your backyard or streets, so it is important to know what to look for.  Remember to map every sighting on KoalaTracker.
