On the Coromandel range near Paeroa this development of mature grassland from virgin bush has been accomplished on an area of about 1 200 ha of hill country rising from 30 to 500m above sea level. Only about 5% of this country is ploughable but most of it is "riding" country. The rainfall ranges from 1 500 to 2 500 mm depending on elevation and is fairly evenly spread over the year. In fact, it is often very difficult to get a burn even in the driest months.
