Koala Population Model
This model simulates the growth and decline of koala populations over a period of fifty years taking into account both positive and negative factors.
This takes in four factors that contribute to koala decline in koala populations: Disease, Old Age, Killed Koalas and the amount of habitat. The chosen disease chosen was Chlamydia because it regularly affects koala populations. The factors that affect the amount of koalas killed include predators both natural and domestic and deaths that occur due to vehicles. The koala habitat directly affects both the koala population growth and decline. The amount of habitat that is available is affected by the amount of bushfire that occur yearly, Myrtle Rust disease and destruction due to Urban development.
The positive factors that can contribute to the growth of the populations or mitigate some of the negative factors include: Vaccines, Forest protection, Predator control, Fire prevention and predator control.
The outcome of this model at the end of the simulation period is the best possible outcome because it sees a growing koala population as well as growth of the amount koala habitat and lowers the amount of bushfire and land clearing that occur and the deaths caused by predators and cars.
