A number of threatened species and plant communities are conserved within the park. It protects part of the only known population of Carpenter Rocks Manna Gum (''Eucalyptus splendens'' ssp. ''arcana''), which is a newly-described species, along with several other plants of national, state or regional significance. The park protects significant habitat for the Orange-bellied Parrot (''Neophema chrysogaster''), which is critically endangered at a national level. This important threatened species was recorded more regularly at the Carpenter Rocks site than at any other site in South Australia during the 1980s and early 1990s.〔
