Perenjori Hills Sanctuary

Biodiversity and Conservation project

Advancing Biodiversity Protection in Western Australia’s wheatbelt

The Perenjori Hills Sanctuary is a bold, science-led conservation initiative protecting over 1,000 hectares of critical habitat within one of the world’s 36 global biodiversity hotspots: Southwest Australia.

Located in the heart of the Yarra Yarra Biodiversity Corridor, this sanctuary supports rare and threatened species, ancient plant communities, and delicate ecosystems increasingly impacted by habitat loss, invasive species and climate stress. As part of Australia’s largest carbon-based reforestation initiative, its conservation is guided by Carbon Neutral’s Citizen Science program—bringing people closer to nature through hands-on ecological exploration and monitoring.

This is no ordinary conservation sanctuary.

In 2023, the Perenjori Hills Sanctuary was officially declared a Critically Endangered Ecological Community—a designation that prohibits land clearing and highlights the urgent need for protection.

The sanctuary encompasses a rich variety of ecological zones, including:

  • York Gum and Gimlet woodlands
  • Mallee scrub and Bowgada thickets
  • Banded Ironstone Formations (BIF)
  • Acacia shrublands on pink loams and granite soils

These woodlands, ridges, and scrublands represent the last strongholds of biodiversity in a region that has been extensively cleared since the early 1900’s, with over 90% cleared.

Together, these habitats support an extraordinary array of native biodiversity, including:

217 NATIVE FLORA SPECIES

many endemic to the region

90 BIRD SPECIES

Including the threatened Malleefowl

43 FROG AND REPTILE SPECIES

including the Gilled Blue-tongue Skink

20 NATIVE MAMMALS

with 8 bat species and high echidna density across multiple habitat types

Little Woodswallows
Echidnas
Perentie
Malleefowl

First-ever sightings in the WA wheatbelt

In a remarkable discovery, motion sensor cameras installed in the Sanctuary have recorded two elusive, Conservation Priority mammal species:

  • The nocturnal Woolley’s Antechinus (Pseudantechinus woolleyae)
  • Long-tailed Dunnart (Sminthopsis longicaudata)

These are the only known sightings of these two species in the wheatbelt — both listed as Conservation Priority under Western Australian legislation.

Their presence not only elevates the ecological significance of the Sanctuary, but also highlights the importance of protecting upland banded ironstone formations (BIF) — critical, overlooked refuges in fragmented landscape.

“These discoveries reshape what we know about small mammal persistence in the wheatbelt.”

A Smarter Way to Fund Conservation

Legal land protection helps prevent deforestation and land clearing — but it doesn’t cover what matters most for long-term ecosystem health:

The Perenjori Hills Nature Credit Scheme

A transparent, science-backed way to fund conservation and drive lasting biodiversity restoration. This scheme supports the recovery of a critically endangered ecological community and delivers measurable, long-term impact.

Each Nature Credit represents a verified contribution to the health and resilience of native ecosystems, directly funding:

  • Legal protection
  • 20 years of evidence-based ecological management
  • Ongoing biodiversity monitoring and public reporting

This innovative conservation finance tool ensures that critical habitats like Perenjori Hills receive the funding needed not just to survive — but to recover and thrive.

 

What will funding cover?
  • Weed and feral animal control
  • Fire risk management
  • Native habitat restoration planting
  • Ecological monitoring and scientific reporting

Without active and sustained land management, even legally protected ecosystems can continue to decline. This is known as the protection gap — and the Perenjori Hills Biodiversity Project aims to close it.

Guided by Carbon Neutral Citizen Science

In the development of its Nature Credits and Sanctuary initiatives, Carbon Neutral has drawn on the invaluable support of its dedicated Citizen Science team to guide ecological restoration and species monitoring efforts.

Led by animal ecologist Dr Nic Dunlop, the team brings deep experience and leadership to the field. A past Chair of BirdLife Australia (WA) and recipient of the Bessie Rischbieth Award, Dr Dunlop has spent over 40 years advancing citizen science and mentoring emerging ecologists through hands-on fieldwork. His work spans roles in research, teaching, and environmental regulation, including his leadership of the Citizen Science for Ecological Monitoring program at the Conservation Council of WA.

By integrating local knowledge with scientific rigour, these volunteers have played a vital role in identifying biodiversity values and informing conservation priorities across the project. Carbon Neutral acknowledges the critical contributions of its Citizen Science team in delivering meaningful community and environmental outcomes, and thanks them for their commitment to advancing nature-based solutions grounded in integrity and impact.
