This October, the Shire of Mundaring is launching an exciting new citizen science program — the Spring Quenda Count — and we need your help!

We’re calling on all Shire residents to observe and record Quenda activity in their gardens over a one-week period in October. Your sightings will contribute to real science - the data collected will feed directly into population monitoring efforts led by the Department of Biodiversity, Conservation and Attractions (DBCA), helping to guide future conservation actions.

Also known as the southern brown bandicoot, the Quenda is a small, ground-dwelling marsupial that plays a vital role in maintaining healthy ecosystems. Unfortunately, it’s also a vulnerable species, under threat from habitat loss, predation and disease.

By keeping an eye out in your own backyard, you can make a real difference to their survival. We’re thrilled to be working with Dr Amanda Kristancic, a leading local wildlife ecologist, to help develop and deliver the program.

Amanda will be offering an in-person presentation to help participants learn how to spot Quenda, record data, and understand the importance of their contributions. If you can’t attend the info session, don’t worry, we’ll record it, and you will be able to watch it online (we’ll put the link on this page).

Join us to shine a spotlight on these special locals and protect them for generations to come.

Learn more by attending the Spring Quenda Count Info Session on Wed 17 Sep, 10am to 11am at Boya Community Centre.

To participate in the Spring Quenda Count, use our survey form to submit your count.

How to Take Part in the October Spring Quenda Count

Thank you for helping the Shire of Mundaring and the Department of Biodiversity, Conservation and Attractions (DBCA) learn more about our urban quendas (bandicoots). Your efforts make a real difference in understanding how these unique animals are coping with the challenges of urban sprawl and loss of natural habitat.

Why join the Spring Quenda Count?

The information you collect helps track the populations of the iconic quenda (Isoodon fusciventer), a species of bandicoot found only in south-west Western Australia.

Quendas aren’t currently listed as a ‘threatened’ species, but they face risks such as:

  • Vehicle strikes
  • Introduced predators (including pet cats and dogs)
  • Habitat loss and fragmentation

Because of these pressures, DBCA lists the quenda as a Priority 4 species, which means it requires ongoing monitoring.

If you’ve joined the Spring Quenda Count before and still have access to your survey area, we’d love for you to take part again this year.

How do I get involved?

Becoming a Quenda Counter is easy! Just follow three simple steps:

  1. Choose your area and dates – Pick a spot on your property to watch for quendas, and decide which day(s) in October you’ll do your counts.
  2. Do your count – Record the number of quendas you see on your chosen day(s). You can count for one day or up to three days.
  3. Send us your results – Fill in the Quenda Count form and return it to the Shire by Friday 14 November 2025.

Choosing your count area

Pick a place on your property where you’ve seen quendas before – perhaps your garden, a patch of bush, or even part of a larger block. An area of around 50m x 50m works well.

If you’ve done the count in previous years and still have access to the same area, please use it again so we can compare results over time.

When to do the count

  • Choose any week in October that suits you.
  • A survey is done on a single day, preferably in the early morning or evening, when quendas are most active.
  • You can do one count or up to three counts in your chosen week. If you do multiple counts, leave 1–2 days between them.

⚠️ Important: Plan your count days in advance. Please don’t wait until you spot a quenda before starting—even a zero count is valuable data.

Estimating your effort

Please estimate how much time you spend actively looking or being “on the lookout” for quendas during each count. This information is crucial for understanding your results.

Being “on the lookout” means you’re in your chosen area and would notice a quenda if one appeared. You can spend as little as 15 minutes or several hours looking for quenda.

How to count quendas

  • Record the number of quendas you see in your area during your chosen time.
  • Avoid double-counting the same animal.
    • Example: If you see 3 quendas at once, record 3.
    • If you later see a different individual, add it to your total. So 1 + 3 = 4 quendas for that count.

What if I don’t see any?

That’s still an important result! A zero count helps us just as much as sightings.

If you don’t see quendas during your count, record “0” along with the time you spent looking. Also, keep an eye out for signs like cone-shaped diggings, and record those too.
