Significance:
The Cleland Swamps contain unique wetland vegetation in South Australia including 34 indigenous plants species. Seven of these are threatened at a State level (National Parks and Wildlife Act 1972) and 15 are threatened within the Southern Lofty Region (Lang & Kraehenbuehl 2001; Florlist 2001). See notable flora for listings. The swamps also contain the Nationally Endangered Southern Brown Bandicoot (Isoodon obesulus obesulus).

Threatened species: Austrostipa muelleri - Rare Southern Lofty, Baumea gunnii - Sr and Rare Southern Lofty, Baumea tetragona - Uncommon Southern Lofty, Blechnum minus - Uncommon Southern Lofty, Blechnum nudum - Sr and Rare Southern Lofty, Empodisma minus - Uncommon Southern Lofty, Gahnia sieberiana - Uncommon Southern Lofty, Gleichenia microphylla - Sr, Rare Southern Lofty, Leptospermum lanigerum - Uncommon Southern Lofty, Lindsaea linearis - Uncommon in southern lofty, Lycopodium deuterodensum - Se and endangered Southern Lofty, Sprengelia incarnata - Sr and Rare Southern Lofty, Thelymitra circumsepta - Se and endangered Southern Lofty, Todea barbara - Se and endangered Southern Lofty.
Notable fauna:
Threatened species: Southern Brown Bandicoot, Isoodon obesulus obesulus (Sv, Ne).
Other Fauna:
Invertebrate: Ostacoda spp. (Seed shrimp), Notonemouridae spp. (Stonefly).
Social and Cultural values:
Recreation and tourism: A very popular walking track connecting the foothills to Mt Lofty Summit passes the Chinamans and Wilsons Bog area. Social and cultural values: Heptinstalls Spring was used as a source of water during the early 1900s.
Land tenure:
Tenure on site: Public. Tenure surrounding: Public.
Current land use:
Current land use on site: Conservation Park. Surrounding land use: Conservation Park.
Disturbance or threat:
Past/present: Pest vertebrate and plant presence. Potential: Unknown.
Conservation measures taken:
Conservation measures: The bog areas of Cleland have received funding through the NHT for on-ground works. This has involved a partnership between Catchment Boards, State government programs (SA Urban Forest Program, BushCare) and National Park Staff and Friends Group. An action plan has been prepared for the management of the bog areas. Eurilla and Cleland Eastern Bogs are identified as an important sites by the Threatened Species Network and Cleland National Parks and Wildlife Office. Current scientific research: Unknown. Current conservation education: Some interpretive signage is provided on the walking track adjacent to the bogs.
