Restored Wildlife Corridors in the Tropical Uplands – an exploration of community reassembly processes

Abstract: Restoring wildlife corridors is an adaptive management strategy for improving biodiversity and repairing forest connectivity in fragmented landscapes. Increasing landscape connectivity allows movement of seeds, pollen, and wildlife between previously isolated fragments, while simultaneously improving the quantity and quality of habitat across the landscape. The world’s first restored tropical wildlife corridor, Donaghy’s Corridor was planted 20 years ago and reconnects the forests of Lake Barrine (498ha) to Wooroonooran (80,000ha) and is providing valuable insights into animal movement ecology and long-term data relating to plant succession. Recent monitoring shows the corridor being utilised by >30 birds, 8 microbats, 10 terrestrial mammals and an echidna. Over 150 plant species have naturally regenerated including species with fruits up to 90mm diameter, dispersed over distances >200m. Many vertebrate colonisers are Wet Tropics endemics: basal plant lineages are well represented. However, a lack of replication in ‘real world’ landscapes is a major drawback in understanding the potential value of restoring corridors as a management strategy.  An expanded study examining two additional re-planted wildlife corridors is now planned. In addition to Donaghy’s Corridor we plan to study corridors linking Lake Barrine to Lake Eacham (Lakes Corridor), and Lake Eacham to Curtain Fig Tree (Petersen Creek Corridor), effectively linking all three fragments to Wooroonooran N.P.  Despite inherent differences in length and landscape configuration, these three examples are effective replicates and in combination with pair-wise comparisons of adjacent intact forest, their study could provide robust data and meaningful insights into the role of restored corridors in fragmented landscapes.


Nigel Tucker is an Adjunct in JCU’S College of Science and Engineering and Director of Biotropica Australia, a local environmental consultancy. He has been involved in ecological restoration since the mid-1980’s, working in north Queensland, Papua New Guinea and Indonesia, across a range of ecosystems.

Amanda Freeman is a freelance ecologist, writer, and educator whose research interests include bird communities and species conservation. Her research in revegetation sites over 20 years has been carried out in association with Griffith University, the School for Field Studies, and as a volunteer.

David Tng is a plant ecologist and biologist with an inordinate fondness for the tropical flora. He is currently the Centre Director of the School for Field Studies based near Yungaburra where his research interests are centred around understanding plant-climate interactions, plant functional traits, and tropical plant ecology. He has had diverse experiences working in forest systems both in Brazil and in Australia and now hope to apply his skills to forest restoration work in the north Queensland region.

We will take a break! See you all in 2022!
