Site GL164

General Land Unit Description:

This site is situated on the level surface of the Dundas Tablelands. Red gums are the dominant vegetation. The dominant soil type is a Brown Chromosol, commonly with a ferric horizon which, in some cases, may be cemented (petroferric). The soil is developed over a highly weathered mottled zone. The mottled zone, sometimes referred to as ‘tiger mottling’, is thought to be the result of fluctuating watertables which occurred mainly in the Tertiary period.
