Koala Population in South East QLD
Assessment 1D

This model shows the different aspects in South East QLD that affect both the growth and decline of the koala population in the region and then attempts to simulate the declining trend of the koala population with reference to these different factors. Please note: the values associated with the koala population are in no way 'real' but are a means to get my point across of the ever decreasing population.

The once thriving population of koalas on Queenslands Koala Coast has dwindled since 1996 from approximately 6000 koalas to just under 2000 koalas in 2010 according to the Queensland Government's Department of Environment and Resource Management. However these figures may be even lower than stated in the report and the Australia Koala Foundation believes that these figures have been skewed so as to not have the koala be listed as vulnerable under the federal government's Environmental Protection and Biodiversity Act.

The Koala Population is declining in South East Queensland. There are multiple reasons for this, almost all of which can be changed through awareness and action. This causal loop diagram illustrates what is decreasing Koala numbers and what steps can be taken to increase numbers over time. Main threats being Climate change, Disease and Domestic threats.

The Koala Coast located in the South Eastern Queensland region cover an area of 375 square kilometres.  In the Koala Population Report 2010 (Department of Environment and Resource Management, 2012), it was noted that the population of 6000 animals between 1996 to 1999 had declined by 26 per cent to an estimated 4,600 animals.  This online model highlights the factors affecting this decline.

This is a model depicting the cycles and events that impact on the population and endangerment of Koalas in SE Queensland.

The following insight shows the breeding cycle of Koala's and extensively highlights the overwhelming problems they face with the ongoing urban development which continues to reduce Koala habitats. The future of Koala's are unknown with government turning a blind eye to the 60% decrease in Koala population in South East Queensland since 1997.
