The Hollow Hunt project aims to build a clearer picture of tree hollow resources across our city with the help of community members.
The project kicks off during Geelong Design Week 2022 and will continue throughout the year.
You don't need any special skills or equipment, just your smart phone. You'll find hollows in streets, parks and reserves right across Geelong but the list below provides additional guidance. When you find a hollow, complete the online form, upload a photo and hit submit.
Your hollow will be reviewed by the City and mapped to the public Urban Forest Dashboard.
Data generated through this project will help the City, scientists, researchers and policy makers to better understand and protect these important natural resources.
How to locate and record a tree hollow
You will find tree hollows in backyards, streets, reserves and parks right across Greater Geelong.
If you have spotted a hollow, all you need is a smart phone to snap a photo and record your findings via the online form.
Keep in mind, a hollow can take 100 years or more to form.
The following list of locations have old-growth trees and are good places to start looking:
Why are tree hollows important?
Most species of eucalypts and other trees with a long lifecycle will develop hollows over time. In Australia, many native birds, mammals and reptiles rely on hollows including bats, frogs, skinks, possums, gliders, owls, parrots, rosellas, cockatoos and kookaburras. Each animal has its own requirements in terms of hollow size, shape, depth and location.
Some introduced species also use hollows and compete with our native wildlife. Increasing urbanisation and other factors have led to a loss of hollow-bearing trees in our environment and this has been listed as a ‘Key Threatening Process’ under the Environment Protection and Biodiversity Conservation Act 1999.
participating in the Hollow Hunt project you agree to have your location data recorded (via the online form). This will only be recorded once to determine the location of the tree hollow. The
information submitted through the form is designed to capture details about
the tree hollow only. Your
personal details will not be made public.
The City values the privacy of every individual and is committed to handling
personal information in accordance with the Privacy and Data Protection Act
2014. This is further articulated in the Privacy and Health Records Council Policy.
Where can I view the data?
You can view the tree hollows map on the Urban Forest Dashboard, along with other interesting facts about the 165,000 trees managed by the City.
