Threatened Species

Listed Threatened species found at Sportsman Creek Conservation Area

The Endangered Brush-tailed Rock Wallaby and Joey photographed at Dangar Gorge. 

Where do they live?

In the past, the Brush-tailed Rock-wallaby was abundant and widespread across the rocky country of south eastern Australia from southern Queensland to Victoria, roughly following the Great Dividing Range. During the late 1800s and early 1900s, it was considered a pest and shot for bounties and hunted for their fur. Around half a million Brush-tailed Rock-wallabies were killed during this time. 

The most arboreal dasyurid (small carnivorous nocturnal marsupials) listed as Vulnerable and Near Threatened on the IUCN Redlist. It is likely this species occur sparsely and discontinuously across their entire range. Their Australian native name is Tuan and have a long black-brush tipped tail. The Conservation Area is providing the necessary habitat for their continued existence. Photographed hunting in shed.

 

The Conservation Area has allowed healthy new stands of Narrow-leaved Red Gum trees to grow in the Open Eucalypt Woodlands.
This species of tree is Listed as E2 which means its distribution is restricted to a range over less than 100 km. They are Endangered and at serious risk in the short term (one or two decades.) Because they are branch droppers nesting hollows appear at an earlier stage.

This Red-backed Buttton Quail is listed as Vulnerable and a Threatened Species in N.S.W. Between 1994 and 2005 only six observations were recorded in N.S.W or (0.75 records per year.) They are nocturnal and crepuscular (twilight) in their activity and forage near the ground for insects and grasses although little is known of their diet. A first time sighting on the Conservation Area. 

“This is the first record of this species in NSW since a report from Tuncurry on February 27, 2014 was accepted by NSW ORAC (Case 652). It is interesting to note that all reports of this species in NSW in the past ten years or so have been in the months from November to February and it is not clear whether this implies that it is migratory or whether it indicates heightened activity at this time of the year.”

Flooding rains have brought out this Giant Barred Frog in the riparian zone on Sportsman Creek. Measuring around 230mm in overall length it surely must be one of the largest Australian species of frog. There are five known species in this genus known at present, all restricted to eastern Australia. Usually found in wet sclerophyll forest and rainforest. “Classified as an Endangered species the females lay eggs onto moist creek banks or rocks above water level from where the tadpoles drop into the water where they hatch. Tadpoles grow to a length of 80mm and take up to fourteen months before changing into frogs. They feed primarily on large insects and spiders.”

Hi Jeff, enjoyed looking through your site with great wildlife photos. Will talk about your frog on Wildlife Wednesday ABC Radio @ 6.25 tomorrow 13/05/2015: It appears to be one of our very largest frogs, the Giant Barred Frog (Mixophyes iteratus) distinguished by the eye colours & body patterns, an endangered species rarely observed so well done Jeff for finding it & taking its photo. What was the location? I will send this photo on to the frog specialists because it may be an important find if my identification is correct. Only a very few communities are known. I.D. confirmed by Gary Opit.

The Powerful Owl is endemic to eastern and south-eastern Australia, mainly on the coastal side of the Great Dividing Range. It occurs in low densities and  a breeding pair will defend a large home range of 400-1450 hectare.”. They are monogamous and mate for life. Note  Squirrel Glider in right talon. Powerful Owl feed mainly on arboreal mammals and bats with birds making 10% of their diet. This bird is an important new sighting for the Conservation Area.
