Toowoomba Escarpment Parks

Subject: research, conservation

Location: Toowoomba, southern Queensland

Since 2020 A Rocha Australia has partnered with the Friends of the Escarpment Parks (FEP), supporting efforts to control weeds and monitor wildlife at three bushland parks managed by Toowoomba Regional Council, as shown on the map on the right.

Nielsen Park is a five-hectare remnant of Blackbutt Eucalyptus pilularis-dominated open forest mapped as an endangered regional ecosystem.


Key outcomes so far:

  • Controlling invasive plants including Lantana and Asparagus Fern, allowing indigenous understorey species to establish
  • Standardised bird surveys (BirdLife Australia 2.0 ha 20 min method), monthly for two years followed by more intensive quarterly surveys 
  • Remote camera monitoring

Results show an over-abundance of aggressive bird species, typical of the urban location, and few small bush birds – in part also due to the park’s isolation and poor connectivity to other forest areas. Painted Buttonquail Turnix varius were discovered in the park and other small birds have returned, including two breeding pairs of Eastern Whipbirds Psophodes olivaceus, bowerbirds and visiting owls and frogmouths.

Redwood Park is a much larger council reserve on Toowoomba’s eastern escarpment. Cat’s Claw Creeper Dolichandra unguis-cati is one of several invasive plants that have smothered trees and shrubs in semi-evergreen vine thicket (‘softwood scrub’ or ‘dry rainforest’), an endangered ecosystem. It is home to several threatened species at risk of habitat loss, including Black-breasted Buttonquail and Powerful Owl Ninox strenua as well as fruit bats and orchids.


Key outcomes so far:

  • Slow and labour-intensive removal of Cat’s Claw Creeper, freeing native vegetation
  • Remote camera monitoring in treated areas

Results show confirmed breeding by the Buttonquail and presence of wallabies, possums, Monitor Lizards and a suite of various birds.

Duggan Park contains near-continuous woodland and forest on the city’s eastern edge. Toowoomba Regional Council has invested substantially in making this popular park accessible to people with disabilities. A Rocha Australia started working in this park more recently.

Key outcomes so far:

  • Controlling invasive plants including Lantana and Asparagus Fern, allowing indigenous understorey species to establish
  • Standardised bird surveys (BirdLife Australia 2 ha, 20 min method) monthly
  • Remote camera monitoring

Results show a diversity of bird species (57) due to better woodland connectivity. After a series of high rainfall years, breeding Painted Buttonquail were seen; other ground-feeding species included Wonga Pigeon Leucosarcia melanoleuca and Brown-capped Emerald Dove Chalcophaps longirostris

A Rocha Australia hopes that involvement in these community projects will encourage greater engagement of Toowoomba churches in creation care.

Project: Hart Road Wetlands

Subject: research, conservation, education

Location: Hart Road Wetlands, Aldinga, SA

Traditional lands of the Kaurna people 

The Hart Road Wetlands project south of Adelaide in South Australia began in 2020 in a reserve owned and managed by the City of Onkaparinga council.

Situated on a coastal plain behind Aldinga Beach, this system of artificial wetlands treats urban stormwater but was also designed to provide habitat for wildlife. Public walking paths traverse the reserve and Aldinga Scrub Conservation Park is adjacent.

Activities have involved local residents and others connected with A Rocha Australia in South Australia. 

Key outcomes so far:

  • weed and rubbish removal
  • revegetation with indigenous plant species
  • standardised seasonal bird surveys (BirdLife Australia 2.0 ha 20 min method)
  • outdoor education lessons with local Christian college classes 
  • support of local community events, including traditional reed weaving 

Results show 79 bird species recorded over three years of surveys and an emerging picture of bird usage of different habitats across the wetlands. Species of ornithological interest include Peregrine Falcon Falco peregrinus, Lewin’s Rail Lewinia pectoralis, Baillon’s Crake Zapornia pusilla, Spotless Crake Zapornia tabuensis, and Crescent Honeyeater Phylidonyris pyrrhopterus.

Mount Sandy Project

Project: Mount Sandy

Subject: research, conservation

Location: Meningie, SA

Traditional lands of the Ngarrindjeri people

Cassinia Environmental has a partnership site near Coorong Lakes. The overall goal here is to improve the extent and condition of Coastal Mallee and Swamp Paperbark vegetation. This is a model for sustainable landscape protection and restoration through community partnerships, here with the Ngarrindjeri people. This video profiles the Cassinia and Mount Sandy partnership.

In 2022 A Rocha Australia started to help at this site in South Australia with revegetating cleared farmland. Locally indigenous plants are being propagated in the Raukkan nursery. Over the last two years, thousands of tubestock have been planted.

In September 2023 Wilderlands Australia ecologists led a spring walk in the conservation area, revealing an amazing array of flowers. The Orchid Society of South Australia has been invited to help identify the diverse range of orchids and catalogue the number of rare Metallic Sun-Orchids.

A Rocha Australia looks forward to helping at this site regularly.
