The value of agricultural and forestry output is heavily concentrated in field crops, meat, and dairy products, with most of it coming from animal husbandry. Because large parts of Austria are mountainous, only the lowland areas of eastern Austria and some smaller flat portions of western and northern Austria are suitable for crop production and more intensive forms of animal husbandry. The remainder of the land is used for forestry and less intensive animal husbandry, most of which takes advantage of mountain pasturage.
