Cootamundra Wattle leaf

The Cootamundra Wattle, Acacia baileyana is an introduced and highly invasive species; the Silver Wattle, Acacia dealbata is native to Mt Majura and Mt Ainslie. Both wattles have blueish-grey-green leaves and flower early in spring.

They can be distinguished readily by their leaves.

The compound leaves are called bipinnate leaves: pairs of leaflets or pinnae (singular: pinna) are arranged along the main leaf stem (rhachis), and pairs of pinnules – the smallest unit of the compound leaf – are arranged along the stem of a pinna. The bipinnate leaves of Cootamundra wattles have 3-4 pairs of pinnae, the lowest pair is shorter, swept back and embraces the stem to which the leaf is attached. The bipinnate leaves of Silver wattles have 8-20 pairs of pinnae attached to the rhachis; the lowest pair is not swept back.

Woody weed working pair.

Cut stems close to ground level and immediately treat cut surface with herbicide glyphosate (Roundup or equivalent product) applied at high concentration e.g. 1 part glyphosate : 2 parts water; apply herbicide mix with spray.

The plant’s natural protective mechanism acts very quickly to seal off the cut surface which stops herbicide penetration into the sap stream. It is therefore important to treat the cut surface immediately, i.e. within 30 seconds after cut; the longer the treatment is delayed, the poorer the result will be. If necessary cut and treat each stem of a multi-stemmed plant such as Briar Rose separately to avoid a delayed herbicide treatment.

When: Sunday 17 August from 1.00 to 3.00pm
Where: Old Ainslie tip site off Philip Av Kellaway St Nature Park entrance (see map below)
Bring & Wear: sun protection, appropriate clothing, gloves, buckets, and a shovel if you have one

More than 120 volunteers helped planting 380 local trees and shrubs at the old Ainslie tip site on National Tree Day, Sunday 27 July (Report: Great Community Spirit at National Tree Day). Friends of Mount Majura and the Mount Ainslie weeders are now inviting volunteers to come along and help spreading two truck loads of wood chip mulch. This will suppress weeds and give the young seedlings a head start in the growing season.

The Eucalypts and Wattles

Australian vegetation, with the exception of smaller patches of rainforest and chenopod shrublands, is characterised by large tracts of eucalypt and acacia dominated forests and woodlands.

The genera Eucalyptus, Corymbia and Angophora (eucalypts, bloodwoods and false apples) comprise more than 900 species (800, 114 and 15 respectively), the vast majority of which are only found in Australia. Size varies enormously with species, ranging from the Mountain Ash (Eucalyptus regnans) forests of Victoria with giants greater than 90m tall to the dwarf Varnish Gum (Eucalyptus vernicosa) which often grows as a 1m dwarf shrub in windswept Southwest Tasmania.

The genus Acacia (wattles) is equally diverse and comprises more than 1500 species worldwide, more than 960 of which occur in Australia and all but 16 of these are only found in Australia. Although generally smaller in stature and often found as small undershrubs in many communities, Acacia tends to be dominant in inland Australia with such species as Mulga (Acacia aneura) and Brigalow (Acacia harpophylla).

In New South Wales, we find 264 species of Eucalyptus, Corymbia and Angophora (240, 10 and 14 respectively) and more than 235 species of Acacia (Harden 2002). This diversity of eucalypts and wattles is a reflection of the strong environmental gradients (climate, geology, soils) found within New South Wales, particularly those areas falling within the Sydney Basin geological area stretching from the Hunter Valley to Nowra and west to the Blue Mountains. The Great Escarpment in this area has been eroded from east to west forming intricate series of ridges and valleys. The complexity of this landscape is increased as it is interspersed with areas of residual basalt and old sandstone plateaus with complex drainage patterns all of which leads to a diversity of environmental combinations of slope, aspect, parent material, soil fertility, drainage, rainfall and temperature.

In the ACT, we also have some steep environmental gradients ranging from Mt. Bimberi (1900 m) in the Australian Alps to Lake Burley Griffin (550 m), with sometimes abrupt changes in eucalypt dominants. Eucalypts are the dominant trees of the woodlands and open forests of Mount Majura and Mount Ainslie and of the 25 species of eucalypt indigenous to the ACT, 9 species occur on Mt. Majura and Mt. Ainslie, although there are also some planted non-local native eucalypt species on the edges of the reserve. Additionally, of the 23 species of wattle that occur in the ACT (including 2 naturalised native species), 9 species occur on Mt. Majura and Mt. Ainslie (including the 2 naturalised native species Acacia armata and Acacia baileyana).

Identification

The genus name Eucalyptus derives from Greek “eu ” meaning well and “kalyptos” meaning covered. It refers to the ‘cap’ of the flower bud, which breaks off and falls away at flowering to uncover the pollen rich stamens and nectar laden receptacle of the young ‘gum nut’. It can take between one and two years between initial bud formation and final flowering. Eucalypt buds and mature gum nut fruits are key elements in identification of species as many of the species look quite similar. Primary distinguishing features of eucalypts are:

the shape of flower buds and the number of buds that form a cluster,
the shape of fruits (gum-nuts)
the bark type (e.g. smooth or rough),
the shape of juvenile (seedling leaves / leaves that occur after fire) and adult leaves,
the natural occurrence of species.

Wattles require a different approach and one of the major considerations in identification is whether the adult leaves are bi-pinnate or whether they are phyllodineous (i.e. instead of a true leaf, this latter group has modified leaf stalks acting as ‘leaves’). When young, all species of wattle have bi-pinnate leaves, but only some species retain this feature as adult plants. Other features useful in telling species apart are flower type (e.g. globular heads, elongated spikes) and legume (seed pod) shape and size.

Talk by Belinda Cooke, Swift Parrot Recovery Coordinator
When: Tuesday 20 May, 7.30pm
Where: Blue Gum School Friends’ Lounge, Hackett shops
Swift Parrots migrate the longest distance of any parrot in the world. They leave their breeding grounds in Tasmania in autumn to forage on the mainland. Hear about the endangered birds and their visits to Mount Majura and view a documentary with fabulous footage by local ornithologist Geoffrey Dabb.

Endangered Swift Parrots visit Mount Majura

Since mid April 2008 bird watchers have observed more than 20 swift parrots at a time weaving through the canopy of the tall box trees around the drain line at the lower Hackett reservoir. A Hackett resident noticed a small flock as far back as March 2008. In March and April 2005 Mount Majura hosted more than 60 swift parrots, a number never before recorded in the ACT. The parrots were not recorded during 2006 and 2007.
The swift parrot Lathamus discolor is bright grass green in colour, and has patches of red on the throat, chin and forehead, which are bordered by yellow. It also has red on the shoulder and under the wings and blue on the crown, cheeks and wings. A distinctive alarm call of kik-kik-kik, usually given while flying, a streamlined body, a long tail and flashes of bright red under the wing enable the species to be readily identified.
Swift parrots breed in Tasmania and migrate to mainland Australia in autumn. During winter the parrots are semi-nomadic, foraging in flowering eucalypts mainly in Victoria and New South Wales. Small numbers of swift parrots are occasionally recorded in the ACT, south-eastern South Australia and southern Queensland. The parrots choose larger trees for foraging and feed extensively on nectar and lerp from eucalypts during the non-breeding season.
