In 1980, the conservation park was described as follows:[5]Myponga Conservation Park preserves an area with a diverse and interesting flora that supports a mammalian and avian fauna representative of that of the Fleurieu Peninsula of particular note is the presence of the locally endangered short-nosed bandicoot (Isoodon obesulus) and the rare plants Casuarina striata and Cheiranthera cyanea… This park which occupies hilly terrain typical of the Fleurieu Peninsula, contains a diverse flora that falls into three main structural forms.

The areas of better soils near creeks and along ridges have a low open forest of Eucalyptus leucoxylon and obliqua.

Open scrub of E. cosmophylla with depauperate E. fasciculosa and E. leucoxylon over a dense understorey of Hakea, Banksia and Xanthorrhoea series covers the hill slope areas with patches of closed heath of the same species… Myponga Conservation Park is substantially undisturbed although surrounded by cultural environments.The conservation park is classified as an IUCN Category III protected area.
