Approximately 100 local native terrestrial and aquatic plant species have been planted to maximise diversity, habitat and serve as a resource (nursery) for other projects.
Over 90 bird species have been sighted, and four species of bats. Water based animals include four frog and over 50 macro invertebrate species, Murray River Rainbow fish, Mountain Galaxia and yabbies.
One of the landscaping aims at the Wetlands was to recreate a landscape as it might have been in 1836, prior to European settlement.
Since 1997, the wetland site has been vegetated by students and Friends of Urrbrae Wetland, using plants grown from seed or cuttings of local provenance. These have been collected under permit in the Mitcham foothills, Southern Adelaide Plains, Belair National Park and the Lower Sturt River.
Some of the species planted include: Grey Box (Eucalyptus microcarpa), South Australian Blue Gum (Eucalyptus leucoxylon subsp leucoxylon), River Red Gum (Eucalyptus camaldulensis), Sweet Bursaria (Bursaria pinosa), Golden Wattle (Acacia pycnantha), Kangaroo Thorn (Acacia paradoxa), Native Lilac (Hardenbergia violacea) and Kangaroo Grass (Themeda triandra).
In an aquatic environment, plants play a key role in reducing water velocity, removing nutrients, oxygenating water and providing habitat and food for fauna. Aquatic plants common to the wetland include the Common Reed (Phragmites australis) and other sedges and rushes.
