Over 1,650 native floral and faunal species have been recorded in Ipswich. Of these, 31 are currently listed under Queensland’s Nature Conservation Act 1992 as threatened. An additional seven species are considered to be near threatened whilst another 28 species, considered as common or near threatened wildlife under legislation, have been identified to be of particular local significance due to elevated levels of threat leading to local decline or are of a particular iconic value within Ipswich.
The Australian Government’s main environmental legislation, the Environment Protection and Biodiversity Conservation Act 1999, lists 65 threatened species potentially present within the Ipswich Local Government Area.
Three local fauna species and two flora species have been identified as a priority for protection and conservation planning activities within Ipswich. These are:
The Brush-tailed Rock Wallaby mainly resides on rocky escarpments, granite outcrops and cliffs. In Ipswich it is most commonly found in the Flinders-Goolman Conservation Estate, the closest known population to an urban centre.
The main threat to their survival is the loss of habitat due to clearing of native vegetation, fires and competing for food with introduced pest plants and animals and livestock.
The Brush-tailed Rock Wallaby is the faunal emblem of Ipswich.
The Koala is found in a number of habitats, from coastal islands and tall eucalyptus trees to low woodlands inland. They have a very restrictive diet and don’t stray far from good eucalypt habitat. The Koala’s existence is threatened due to a variety of issues, including habitat loss and fragmentation, unmitigated bush fire, dog attacks, vehicle strike and disease.
The Platypus lives in burrows in river banks near slow-moving water bodies and is currently under pressure from declining water quality, pollution and loss of aquatic habitat. Evidence shows that platypus numbers are steadily declining and there is recognition that a better understanding of the distribution and viability of the species is needed.
Recent surveys show evidence of platypus living in Ipswich waterways. Continued implementation of catchment management actions will contribute towards improved waterways for platypus to live in.
Plunkett mallee is a multi-stemmed eucalypt which occurs in only a few small scattered populations throughout South East Queensland. Within Ipswich, natural populations occur in Dinmore, Collingwood Park and the White Rock area. The species suffers increased pressure as a result of clearing, grazing and inappropriate fire regimes.
Plunkett mallee is Ipswich’s floral emblem.
To date, the Cooneana Olive has only been recorded as occurring in Ipswich, found within three closely clustered sub-populations (17 individual specimens in total)10. Protection of the species will require a coordinated effort including mitigation of imminent threats and implementation of a recovery program.
