City Nature Challenge bioblitz

Calling all citizen scientists! Be part of the City Nature Challenge and join us for a short walk in the surrounding bushland of Mount Kuring-gai Oval to record wild plants and organisms using iNaturalist.

This activity is part of the City Nature Challenge from 25-28 April 2025, where thousands of people across the world will be using their mobile phones to record observations of nature over a few days.

Cities around the world compete and collaborate to find species, make observations, and connect people with nature in urban areas. It started in 2016 as a friendly contest between San Francisco and Los Angeles. Since then, it has grown into an international event, with over 700+ cities participating in 2025.

Join other keen iNaturalist users to add observations for Greater Sydney, of which Hornsby Shire is a part of or learn how to use the citizen science app iNaturalist to record wild organisms around you.

Please come ready with iNaturalist on your mobile phone, a bottle of drinking water, hat and sturdy footwear. Find out more about iNaturalist on our website.

Morning tea will be provided. Please make a booking for catering purposes.
