MANDOON BILYA BIOBLITZ: 13 - 19 OCTOBER 2025
Mandoon Bilya BioBlitz is a free community event to celebrate the incredible ecosystem of the Mandoon Bilya (Helena River).
The BioBlitz is part of our BoorYul-Bah-Bilya program, which is all about restoring ecosystems, reinvigorating cultural heritage, and reconnecting communities to rivers. It will include:
BioBlitz Events: A week of BioBlitz activities from Monday 13 October – Sunday 19 October at public parks along the lower river.
BioBlitz Festival: A free community festival on Saturday 18 October at Mundaring Sculpture Park with guest speakers, live performances, family activities, giveaways, community stalls and food trucks.
DIY BioBlitz: Upload photos of plants, animals and fungi on the lower river to iNaturalist and share your discoveries on social media (#MandoonBilyaBioBlitz).
WHAT IS A BIOBLITZ?
A BioBlitz is a snapshot study where scientists and the community record as many plant and animal species as possible at a location within a set timeframe.
These large-scale citizen science events are fast becoming a popular way to catalogue biodiversity and provide a platform for environmental education. For more information, visit The Australian BioBlitz Hub.
The Mandoon Bilya BioBlitz will allow us to collect important biodiversity data, increase knowledge of the river’s ecosystem, and encourage participation in community-led science and conservation.
It will support our BoorYul-Bah-Bilya program and related initiatives including the proposed Mandoon Bilya Regional Riverpark and community catchment plan, and inform future river restoration efforts.
MANDOON BILYA BIOBLITZ EVENTS
In partnership with Edith Cowan University’s School of Science, we are hosting a week of guided BioBlitz events with local schools at parks along the lower river.
Participants will learn from Noongar Elders and scientists about the river’s significance and its ecological and cultural values.
We also need the community’s help to collect data! Get involved by:
- Visiting local parks along the lower river between 13-19 October
- Recording plants, animals and fungi you find in the iNaturalist app and sharing your discoveries on social media (#MandoonBilyaBioBlitz).
Check out the iNaturalist website for more information.
mandoon bilya bioblitz locations
The BioBlitz is focused on the lower Mandoon Bilya (Helena River) to align with our proposed Mandoon Bilya Regional Riverpark project.
Much of the lower river is inaccessible due to private property or safety concerns, so BioBlitz activities can only be undertaken at public parks where it is safe to do so, such as:
- Kings Meadow Reserve, Guildford 6055
- Helena River Parklands, Guildford 6055
- River Bank Reserve, South Guildford 6055
- Holmesdale Park, Woodbridge 6056
- Opposite Broz Park, Helena Valley 6056
- Riverside Park, Helena Valley 6056
Tread carefully, leave only footprints and take only iNaturalist observations!
