Plants and animals protected in this park
Animals
-
Eastern water dragon (Intellagama lesueurii lesueurii)
The eastern water dragon is a subaquatic lizard found in healthy waterways along eastern NSW, from Nowra to halfway up the Cape York Pensinsula. It’s believed to be one of the oldest of Australian reptiles, remaining virtually unchanged for over 20 million years.
Plants
-
Grey mangrove (Avicennia marina)
Grey mangrove is the most common and widespread mangrove found within intertidal zones across Australia, and throughout the world. Growing to a height of 3-10m, they thrive best in estuaries with a mix of fresh and salt water. They excrete excess salt through their long thick leaves, and absorb oxygen through their aerial root system.
-
Old man banksia (Banksia serrata)
Hardy Australian native plants, old man banksias can be found along the coast, and in the dry sclerophyll forests and sandstone mountain ranges of NSW. With roughened bark and gnarled limbs, they produce a distinctive cylindrical yellow-green banksia flower which blossoms from summer to early autumn.
-
Grass tree (Xanthorrea spp.)
An iconic part of the Australian landscape, the grass tree is widespread across eastern NSW. These Australian native plants have a thick fire-blackened trunk and long spiked leaves. They are found in heath and open forests across eastern NSW. The grass tree grows 1-5m in height and produces striking white-flowered spikes which grow up to 1m long.
-
Scribbly gum (Eucalyptus haemastoma)
Easily identifiable Australian native plants, scribbly gum trees are found throughout NSW coastal plains and hills in the Sydney region. The most distinctive features of this eucalypt are the ‘scribbles’ made by moth larva as it tunnels between the layers of bark.
