We love seeing the many wombats ambling around the stunning landscape of Flinders Island and are always keen to learn more about the wildlife we encounter. We caught up with UTAS researcher, Dr Scott Carver, to find out more about recent bare-nosed (or common) wombat research and another topical wombat issue, mange. The full story can be found here.
1. What did your research find?
We gained a far deeper understanding of the population’s genetics with the key findings being:
a) Confirmation of three sub-species- the SE Australian mainland, Tasmanian mainland and Bass Strait Islands.
b) The healthy population on Maria Island is genetically of the Bass Strait sub-species.
c) Across Tasmania wombats more geographically distant from one another were more genetically distinct than individuals sampled nearby.
d) There are more Bass Strait wombats than previously thought – a very welcome finding.
2. Why is this research important?
It helps us manage the wombat populations, especially when translocation is being considered as the research advises against this. The other important implication is for orphaned wombats to be released as close as possible to where they came from.
3. Wombat mange has been in the news here – what exactly is it?
Mange is a disease caused by microscopic mites that burrow into the skin. Mange actually affects over 100 species worldwide, including humans (scabies). Wombats don’t cope well with the mites and suffer a slow, painful demise.
4. What impact has mange had on the wombat population in Tasmania?
There have been heavy impacts on some local populations, eg Narawntapu National Park in northern Tasmania. A severe outbreak beginning in 2010 has caused the population to crash over a number of years. There is good news however – the wombat population state wide has actually increased over the last 30 years.
5. What is being done about mange?
The current treatment regime needs repeated applications and to be honest, wombats are bad patients! As they start to improve, they become more reluctant to be treated and often change burrows. We are currently trialling a new, longer lasting, single dose treatment on wombats and hope to have the results of that soon.
6. Bonus question for wombat lovers! What’s quirky about them?
Here’s the first few Scott mentioned, read the full article for them all!
• Firstly and obviously there’s the cubic scat! (We loved this video of the cubic scat that just won the Cradle Mountain Film Fest best short film)
• Their rump is thick hardened skin (not cartilage as some think).
• They can run up to 40kmh, which is a little faster than Usain Bolt.
