Model Answer

The line graph indicates the population density of native mammals in the Carnarvon National Park during a 70-year period. This is compared to the population of introduced mammals. Native mammals include kangaroos, wallabies, koalas, and possums and introduced mammals include pigs, cats, and goats.

In general, the number of native mammals decreased during the given period while introduced mammals showed an overall growth in their population.

In particular, native mammals were at a density of approximately 12 per hectare in 1930. This number remained constant until 1950. In the following years it dropped moderately to under 5 in 1975. There was a slight fall to roughly 4 in 2000.

The population of introduced mammals was only about 1 per hectare in 1930. This figure grew slowly at first but rose moderately after 1950 to plateau at about 11 in the late 70s. A further rise started in 1990 when the number reached a peak at around 12 in the late 90s. Since then, there was a moderate decline in the number. In 2000 fewer than 10 introduced mammals existed per hectare.
