TREES AND THE PERMANENT LANDSCAPE

 

   Native Australian trees grow rapidly or slowly according to the condition of their soil climate.

   On a property being Keyline improved, the growth of the trees will reflect the development of the improving soil and play an important part in the new landscape.

   Upper right: "Nevallan", the naturally short-lived black wattles, seen between the planted belts, have reached their peak and are dying off and will be removed this year. Our planted tree belts replace them, becoming effective wind breaks. They are longliving and produce valuable timber.
