The Cooperative is an area of exceptional Biodiversity. The 1st paragraph of Ecological Perspective’s 2013 Report clearly defines this: 


The Round the Bend Conservation Co-operative (RTBCC) is a unique residential conservation co-operative that lies within the Bend of Islands (BoI), Victoria.  Land owned by the RTBCC is characterised by large areas of contiguous remnant bushland, which is considered high quality, in both a local and regional context.  The site is recognised as a DSE BioSite of state significance (BioSite Number 4706) (DSE, 2012a), and is considered to make a high contribution to protecting the strategic natural values of the state (DSE, 2011b). It is also nominated as a site of state faunal significance (Site 60 – Round the Bend Cooperative – Maroondah Aqueduct), in addition to providing habitat connectivity between Warrandyte State Park and Kinglake National Park (Beardsell, 1997).

The diversity of habitats on the Cooperative support an equally diverse range of fauna.

Overall a total of 166 native and twelve introduced species have been recorded on or immediately adjacent to the Co-op.  The native species include 126 species of birds (one Endangered, six Vulnerable and two Near-Threatened), 20 species of mammals (three Vulnerable), 13 species of reptiles (one Vulnerable) and 7 species of amphibians (one Vulnerable).

A broad range of invertebrates have also been recorded.  Identified species include 34 Butterflies,  24 Dragonflies, 30 Lacewings and 350+ Moths.

Tuan or Brush-tail phascogale

There are a number of threatened species such as Brush-tailed phascogale, Grey-headed Flying-fox (winter visitor that comes some nights to feed on the flowering Ironbarks), White-throated Nightjar (breeding summer migrant from New Guinea), Powerful Owl, Common Dunnart, Spotted Quail-thrush, Grey Goshawk, Lewin’s Rail and Swift Parrot.


Many insects are also extremely rare.

The dry, sparse Box-Stringybark Woodland on our property is the preferred habitat of the Brush-tailed Phascogale and specific management strategies have been developed to conserve this species on the Co-op.

The Powerful Owl requires in excess of 1000 hectares to survive and the Co-op provides important hunting and roosting habitat within the home range of at least one breeding pair resident within the Bend  of Islands.
