These images show Wyperfeld National Park, Victoria, in southeast Australia . Grazing land appears pink, and cropland is a green-yellow pattern.
Fires occur in the park almost every year, leaving huge fire scars .
This area's dry climate lies between wet coastal forest and interior desert. Within these images , the Wimmera River flows from the wetter south to the drier north, where it dies in a chain of lakes. From the 1840s on, much of this bush was burned off to clear land for farming. Wheat yields in this region were high, so people tried farming even the areas with poorer or sandier soils. These sandy areas can be seen in the Landsat images as sand ridges in the park, and as pink areas outside the parks, representing grazing land.
