Plants
Nearly the entire vegetation of the park has been cleared in the past and very little natural vegetation remains.
Important stands of Grey Box eucalypts are found throughout the park and include vegetation communities which are poorly represented throughout the Adelaide hills.
Other species include:
- Golden Wattle
- Bull Oak
- Melaleuca species
- Grevillea and Hakea
- River red gum.
Various organisations and volunteers have undertaken tree planting, enabling the area to develop into an important and attractive urban bushland resource.
Animals
As the revegetation of the park continues and matures, more species of woodland and grassland birds are being recorded. Many species of reptiles thrive in the open grasslands of O'Halloran Hill Recreation Park. There is a small population of western grey kangaroos that call O'Halloran Hill home. There is also the occasional koala passing through the area.
