In parks where koala densities are unsustainable, the koalas' source of food, largely Manna Gums, can be over-grazed. This defoliation causes the trees to die, leading mass starvation of the koala population.
Parks Victoria uses three strategies to manage unsustainable koala populations:
- Fertility control – use of contraceptive implants
- Koala relocation
- Habitat manipulation - protection of individual trees
Once populations are at sustainable levels ongoing management is needed to ensure that population sizes are maintained.
Koala management programs are in place at:
- Mount Eccles National Park
- Snake Island
- Raymond Island
- French Island National Park.
OutcomeWhere management programs have been in place over a number of years, monitoring of population levels has shown they are reduced to sustainable levels.
