GL165

Site: GL165	Land Unit: Dundas Redgum
*Aust. Soil Class.:* Ferric, Mesotrophic, Brown KUROSOL (confidence level 1)

General Land Unit Description:
This site appears to be a small patch of Tertiary capping, surrounded by rhyolite. The vegetation is significantly different to the other Tertiary sites, consisting of blackboys and wattles rather than red gums. There is still the presence of the red and white mottled zone (‘tiger mottles’) although they are not as pronounced as the other sites. The ferruginous and manganiferous buckshot that is found at the other sites is absent.

Site Description:

Slope: 9%	Geology: Tertiary sediments
Landform pattern: Undulating rises	Position in landscape: Upper slope / crest
Internal drainage: Moderately well drained
