Habitats for Koalas in the Otways
- YEAR: 2012
- STATE: Victoria
- FOCUS AREAS: Saving Species/SDG 15: Life on Land
Boasting rich biodiversity and stunning landscapes, the Great Otway National Park and surrounding private land is a region of high biodiversity and tourism value, attracting over 7.5 million people a year. It provides the perfect koala habitat and Koalas are a major attraction, occurring at high densities in some areas. However, over-browsing by koalas has contributed to a marked decline in tree condition, particularly Eucalyptus viminalis (manna gum).
The mission of this project is to provide information on koala habitat use, tree species selection, and koala movements between habitats in the Otways. This will help to preserve both the koala population and their habitats for future generations.
This project was funded through generous donations from FNPW supporters across Australia and beyond.
Project overview
This project is all about uncovering the secrets of koala habitat use, tree species selection, and movements between habitats in the Otways region. Also, the project investigates the flow-on impact of koala over-browsing on other creatures such as birds, small mammals, and aboreal mammals in the Eucalyptus viminalis woodlands.
This information is critical for developing a long-term ecological management strategy for both koalas and their habitats in the region. By understanding how koalas interact with their environment, we can develop strategies to protect them and ensure their survival for generations to come.
This research also sheds light on how climate change may be affecting koalas. As temperatures rise and bushfires become more frequent and severe, koalas are facing major challenges. Mortality rates may increase due to their low tolerance for prolonged hot weather, and changes to eucalypt communities could affect the nutritional quality of their leaves. By investigating how koalas respond to these changes, strategies are developed to help them adapt and thrive.
Finally, in areas of mainland Victoria and for some islands where koala densities are locally high, increased browsing pressure on preferred trees is another factor threatening populations. Understanding these threats and how koalas respond to them is critical to the long-term conservation of the species.
