What to expect: 100s of Hawthorns and Sweet Briars.
Bring: Your friends, sun protection, sturdy shoes, body-covering clothing; we provide tools and morning tea.

Sweet Briar or Briar Rose, 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). The Sweet Briar Rose was introduced to Australia in the early 1800’s as garden and hedge plant. The compound Briar Rose leaf comprise 5-9 leaflets with serrated margins.
Hawthorn, Crataegus monogyna, a thorny deciduous large shrub or small to 10m high tree with roughly wedge-shaped, lobed leaves and fleshy up to 1cm wide fruits that turn red when ripe. A native to Europe, Hawthorn was introduced to Australia in the mid 1800s as a hedgerow and ornamental species. It is a highly invasive weed of woodlands and open forests.The seeds are mainly spread by birds.
Hawthorn hosts the Peer and Cherry Slug (Caliroa cerasi), provides rabbit habitat, and – as other autumn-fruit bearing ornamental shrubs such as Firethorn and Privet – has contributed to the increase of Currawong numbers which decimate small woodland birds.
FoMM lobbies the ACT Government to remove 8 large hawthorns at Valour Park located right to the north of Mt Majura nature reserve (letter to the Minster for TAMS, Shane Rattenbury). Approximately 60% of the woody weeds we encounter in the area east of The Fair during follow-up woody weed control sessions are hawthorns.
Cootamundra wattle, Acacia baileyana is an Australian species, which does not naturally occur in Canberra. As many of the environmental woody weeds that we find in the nature reserve, Cootamundras were introduced to the ACT as an ornamental garden and landscape plant. The highly invasive species is now widespread in Namadgi National Park and the nature reserves of the ACT. The compound blueish-grey-green leaves resemble those of the local species Sliver wattle, Acacia dealbata, which native to the Mount Majura and Mount Ainslie nature reserves.
How to tell-apart from look-a-likes. The compound blueish-grey-green leaves of a Cootamundra wattle (top in the right panel) resemble those of the local species Sliver wattle. 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.
