Restoring landscapes across the Mount Alexander Region

Mapping large old trees: let’s celebrate and protect these beauties!

Posted on 28 September, 2023 by Ivan

It has been a little over a year since we announced the arrival of our new mapping portal, aimed at helping community citizen scientists map the old, and often large, trees of Central Victoria.

We have been excited to see the database entries feed in over the past 12 months and we have now reached 25 large old trees entered into the portal. The majority of the entries have been around the Maldon, Welshmans Reef, Chewton, Castlemaine and Guildford areas, with a variety of citizen scientists taking some excellent photos and providing data about the tree species, age, height and habitat values. A special mention must go to Bev Phillips from Maldon Urban Landcare Group (MULGA), who entered a whopping 15 trees into the database. Well done, and a massive thank you, Bev, for your persistence and love for our landscape.

We thought it would be timely to publish the photos entered into the mapping portal so far, to highlight the diverse range of large old trees across our landscape. Interestingly, all of the 25 entries are Eucalyptus species, which are usually the tallest trees in the local landscape. We would love to see some other species mapped and entered, such as the Casuarinas, Acacias, Banksias, Bursarias and other local midstory species.

Please enjoy the images below, captured by our keen citizen scientists over the past 12 months.


The interactive mapping portal is part of Connecting Country’s larger project, ‘Regenerate before it’s too late‘ , engaging the community in the importance of old trees and how to protect them.  Over the next two years (2024-2025), we will continue to host community workshops and develop engagement resources. We will also help local landholders with practical on-ground actions to protect their large old trees and ensure the next generation of large old trees across the landscape.

How to map and enter old trees in our mapping portal

We are asking the community, including landholders, Landcarers and land managers, to map their favourite old trees across our region. Anyone can access Connecting Country’s new online mapping portal. The portal uses BioCollect, an advanced but simple-to-use data collection tool developed by the Atlas of Living Australia (ALA) and its collaborators. BioCollect helps users collect field biodiversity data for their own projects, while allowing the data to be easily copied into the ALA, where it can be publicly available for others to use in research, policy and management. This allows individual projects to collectively contribute to science across Australia.

The mapping portal is now open for any community member to record the old trees in your area. You will need to register with the Atlas of Living Australia (its easy and free), then upload a photo and enter the field details needed for the survey. The portal will ask you simple questions about the tree location, size, species, age (if known), health status and habitat value.

By recording large old trees, you will help build our understanding of the large old trees in our region and contribute to the largest biodiversity database in our country. As the database grows, you can also access the portal to learn about other wonderful large old trees in our area and view the photos.

We are most grateful to the generous project support from the Ian & Shirley Norman Foundation. The foundation aims ‘To encourage and support organisations that are capable of responding to social and ecological opportunities and challenges.’ To learn more about Ian & Shirley Norman Foundation – click here
