Removal of habitat is the single biggest threat to the decline of koalas and all other wildlife in this country. The vast majority of this loss of vegetation occurs as a result of urban development, agriculture, mining and the expansion of existing infrastructure.
There is a saying “death by a thousand cuts” where every single eucalypt tree removed may in itself seem insignificant but as this occurs on a daily basis in locations where koalas live, little by little these important trees are gone from a koala’s home range.
An individual adult male coastal koala occupies up to 100 hectares, an area he occupies for life. Koalas live in a social hierarchy with higher ranking animals occupying the best locations and lower ranking koalas occupying lower quality habitats.
