Sweet Briar, Rosa rubiginosa, a native plant of Europe and West Asia, is a major weed particularly of dry and hilly disturbed land. The seeds are spread by birds and foxes which eat the red fleshy fruits (rose hips). Briars were introduced to Australia as garden and hedge plants in the early 1800s (Photograph Waltraud Pix, 23.11.2011).

Cootamundra Wattle, Acacia baileyana, is an Australian species, which does not naturally occur in Canberra. It was introduced to the ACT as a garden plant. The highly invasive species is now widespread in Namadgi National Park and the suburban nature reserves of the ACT.

How to tell-apart from look-a-likes. The compound blueish-grey-green leaves of a Cootamundra wattle (top in the left panel) resemble those of the local species Sliver wattle, Acacia dealbata, which native to the Mount Majura and Mount Ainslie nature reserves. The leaves of Cootamundra wattles have 3-4 pairs of leaflets arranged along the leaf stem, the lowest pair is shorter and embraces the branch to which the leaf is attached. The leaves of Silver wattles have 8-20 pairs of leaflets arranged along to the leaf stem and the lowest pair does not embrace the branch.
