Why is farming concentrated in the southeast, north, and northwest of Tasmania?

Although Tasmania enjoys a cool temperate climate favorable for agriculture, the state's rugged mountainous terrain and generally poor soil quality limit where arable farming can occur. Consequently, agricultural activity is largely confined to the southeast, north, and northwest regions of the island.1

These specific areas are preferred for farming primarily due to the presence of more fertile soil compared to the rest of the state. While much of Tasmania’s land is characterized by leached, acidic, and low-fertility soils, the northwest, northeast, and southeast contain more productive land, including black earths in the southeast and fertile soils derived from former swamps in the far northwest. These environmental factors, combined with the challenges posed by the island's inhospitable terrain elsewhere, have dictated the concentration of intensive cropping and dairying in these coastal and lowland belts.23
