Have you ever wondered if the air is cleaner in parks compared to busy roads? We’re finding out!

Join us for the Magnetic Leaves Bioblitz, a unique citizen science experience where you’ll play a vital role in a real scientific investigation.

What is a BioBlitz? Think of it as a nature treasure hunt! We’ll be exploring the Woodhaugh Gardens and surrounding area, working together to find and identify as many plant species as possible. But this isn’t just about spotting pretty plants – we’re on a mission to uncover the hidden story of Dunedin’s air quality.

Plant leaves collect magnetic airborne particles, most of which are sourced from vehicle pollution. By measuring the magnetic properties of these leaves, we can assess air pollution levels in different settings – and we need your help to do it! During this hands-on experience, you will learn the basics of biomagnetic monitoring, explore the plant life in the Woodhaugh Gardens, help collect leaf samples for analysis, and contribute to cutting-edge research.

This is a family-friendly event! Whether you’re an adult, teenager, or family with young children (preschool and primary school kids welcome with caregiver supervision), you can be part of this exciting project.

Important Information: Base Camp will be set up at the Woodhaugh Gardens entrance on the corner of Queen St and Inverleith St.

We encourage attendees to download both the 'iNaturalist' and 'Aotearoa Species Classifier' app to their device before the event. We will be using this app to identify plant species for the Bioblitz, particularly natives. If you don’t have these apps with you, you can still participate in the BioBlitz! We will have volunteers on the ground who can upload your observations to iNaturalist on your behalf.

Children are welcome with caregiver supervision.

This event is outdoors and requires walking along mostly flat trails. Wear suitable footwear and dress for the weather. BYO water and snacks. Event organisers will be in touch ahead of the event if the weather is not looking suitable on the day.
