Flora and fauna
The State Park encompasses a range of vegetation communities and habitats including forests, woodlands, shrub lands and heaths as well as special environments such as coastal wetlands and littoral rainforests. The vulnerable plant Thesium australe (Austral Toadflax) has been identified in the Old Bar area.
In line with the varied vegetation types there is a diverse range of fauna found with the Park including many threatened species. The endangered Little Tern has been using Crown land north of Old Bar in the Farquhar and Manning Point areas for breeding and fledgling sites.
The estuary around the Old Bar entrance provides food and shelter for a variety of wetland birds and waders.
