Tasmanian Northern Midlands


The Tasmanian Northern Midlands bioregion is mostly relatively low plains drained by tributaries of the Tamar River in the north and Jordan River in the south. The plains formed on sand, gravel and mud deposited by these rivers and the natural vegetation they supported was predominantly grasslands and grassy woodlands. On its eastern side the Northern Midlands bioregion rises into low, unglaciated hills and mountains formed from dolerite rock that are largely covered with dry sclerophyllous forests. On the western boundary lies the high Lake Country, which was extensively glaciated resulting in a large numbers of lakes carved into the very hard and erosion-resistant dolerite rock.
