The Perth Zoo in Western Australia looks after a Perentie Lizard (mentioned in the last posting) (http://perthzoo.wa.gov.au/animals-plants/australia/reptile-encounter/perentie/).
The Perentie is a Central Australian monitor (also known as a goanna) which is designated a ‘controlled animal’ under the Tasmanian Nature Conservation Act 2002. There is a low likelihood that this species could establish in Tasmania, with potential for minor impacts. The most significant impact is likely to be predation because Perenties have a broad diet and could potentially prey on a variety of native animals. These impacts are likely to be low because the Tasmanian climate is not suitable. This risk assessment categorises Perenties as a moderate threat to Tasmania and proposes that imports be restricted to those licence holders approved for keeping moderate threat species.
I have seen a few lizards during my walks along the Derwent River. Tasmania has fifteen different types of Skinks plus the Blue Tongue Lizard (some live in the rocks in my garden) and the Mountain Dragon. Delicate Skinks are a small, plain species, often found in suburban gardens in northern and eastern Tasmania. Often I see a tiny Skink darting out of my way., but I do not know which type or types: more research is needed. The photo below shows a Delicate Skink.
