The Southern Forests cover quite a large area of the south west. The area around Pemberton is famous for karri, a species of eucalypt, and one of the tallest species in the world. It is not unusual to see trees over 50 metres, and they can grow up until 90 metres. Unlike other big trees, these are relatively fast growing. They can reach heights of 30m within 70 years, and 50+ metres in 100 years. That’s way it is unfortunately the favourite of loggers. Pemberton still has a large mill operating.
