Creating Hindmarsh Valley National Park

A new nation­al park is being cre­at­ed in Hind­marsh Val­ley on the Fleurieu Penin­su­la, nes­tled between Mypon­ga and Mount Jagged.

The 423-hectare por­tion of land was pre­vi­ous­ly owned by SA Water and was trans­ferred to the Depart­ment for Envi­ron­ment and Water in mid-2021.

It was offi­cial­ly pro­claimed as a nation­al park in Decem­ber 2021, ensur­ing the ongo­ing pro­tec­tion of this eco­log­i­cal­ly sig­nif­i­cant land.

In cre­at­ing this nation­al park, con­ser­va­tion is at the forefront.

Where is Hind­marsh Val­ley Nation­al Park?

Hind­marsh Val­ley Nation­al Park is locat­ed approx­i­mate­ly 80 km south of Ade­laide on the Fleurieu Peninsula.

It is near­by to pic­turesque Hind­marsh Falls, and Mount Bil­ly Con­ser­va­tion Park – which also pro­tects impor­tant Fleurieu Penin­su­la veg­e­ta­tion communities.

Why is the site so significant?

Hind­marsh Val­ley Nation­al Park is where you will find the nation­al­ly crit­i­cal­ly endan­gered Fleurieu Penin­su­la Swamps.

These swamps are unique because of their tiered struc­ture, found nowhere else in Aus­tralia. The upper catch­ments enable the for­ma­tion of spring fed swamps at the top of the tiers. These swamps feed per­ma­nent streams dis­sect­ing the south-east­er­ly fac­ing slopes, cre­at­ing moist, shady, mossy areas with fer­tile loamy soils that are unique for the region. This is ide­al habi­tat for the endan­gered Hind­marsh Val­ley Green­hood or Moss Lov­ing Green­hood’ (Pterostylis bryophi­la) found in the area.

The park is also home to two oth­er species of endan­gered plants only found in the area: the Mount Com­pass oak-bush (Allo­ca­sua­r­i­na robus­ta), and Hind­marsh cor­rea (Cor­rea calyci­na var.calyci­na).

It also pro­vides habi­tat for the nation­al­ly-endan­gered south­ern brown bandi­coot, chest­nut rumped heath-wren, nation­al­ly-vul­ner­a­ble bass­ian thrush and local­ly crit­i­cal­ly endan­gered west­ern pygmy possum.

Pro­claim­ing the area as a nation­al park under the Nation­al Parks and Wildlife Act 1972 ensures pro­tec­tion for this spe­cial par­cel of land, the species that live here, and the habi­tat it pro­vides – for now and for years to come.

Devel­op­ment of the park man­age­ment plan

A draft plan for parks of the Cen­tral Fleurieu Penin­su­la was released for pub­lic con­sul­ta­tion and mem­bers of the pub­lic were invit­ed to pro­vide feed­back on the draft plan on Your­SAy.

The plan includes Hind­marsh Val­ley Nation­al Park and 14 oth­er parks across the cen­tral Fleurieu Penin­su­la, includ­ing: Bul­lock Hill, Cox Scrub, Finniss, Gum Tree Gul­ly, Hes­per­il­la, Kyeema, Mount Bil­ly, Mount Mag­nif­i­cent, Mypon­ga, Nixon-Skin­n­er, Scott, Spring Mount, Stip­itu­rus and Yulte con­ser­va­tion parks.

The final plan is now being prepared.

Stay up-to-date with devel­op­ment of the plan by sub­scrib­ing for project updates.

Main­tain­ing the park

While the park man­age­ment plan is devel­oped, work con­tin­ues to pro­tect the land with­in Hind­marsh Val­ley Nation­al Park from fire and intro­duced species.

Park rangers and ecol­o­gists con­tin­ue to main­tain weed con­trol pro­grams, so that native species can sur­vive and thrive.

To assist in the man­age­ment of fire risks, ongo­ing mon­i­tor­ing and removal of dry grass and on ground fuel, fire breaks and fire tracks main­te­nance will be undertaken.
