Projects Update
Over the past few years, we have managed to secure
funding and supplemented by many hours of volunteer
time, undertake a variety of weed management
projects, . Some of these projects have included
significant work on a few residents’ private property.
This, unfortunately, is not sustainable into the future.
This year, we managed to leverage our funds and
volunteer hours, by providing some residents with
chemicals and advice to complete the work
themselves.
The MRLC Inc. future direction for weed management
on private land will need to extend this model where
most if not all the weed control contributions come
from the property owners who benefit from the work.
In consequence our role will shift towards motivating
owners using incentive and technical support. Our
2017 submission to the Clarence City Council Land and
Coast Grant Application reflects this new model.
We are very keen to encourage and support all landowners in the identification and eradication of the environmental weeds that can be found in our environment, particularly, Spanish heath, serrated tussock, gorse, Paterson’s curse, boneseed and broom.

As noted in the editorial, we are moving to a new,
sustainable model of weed management. Our submission to receive funding to engage a weed consultant to work with property owners with priority weeds and high conservation vegetation and habitat, or vegetation that has important landscape connectivity, has been successful. The
weed consultant's role will be focused on 1:1
engagement with property owners to promote
responsibility for implementing regular follow up
weed control. The consultant will provide best
practice weed and habitat management advice as
well as recommending that landowners who have
benefited from previous free support take
responsibility for their weed control into the future.
CCC Land and Coast Care Submission 2017 Spring Bushwalking (by Phil Watson)
When the warmer spring weather and longer days
arrive after a cold winter, walkers are naturally
reinvigorated for a new season of activities. One
benefit of this enthusiasm is an opportunity to enjoy
the kaleidoscope of woodland floral delights and
accompanying insect and birdlife, full of spring-time
zest for feeding and breeding. Walkers are greeted
with colourful carpets of groundcovers, striking
yellow and orange flowers of bush-peas and
attention-grabbing blooms of wattles and gums.
Amongst the many eye-catching forest shrubs are
the distinctive dogwoods (Pomaderris sp.) from the
buckthorn family (Rhamnaceae) which often form
hard-to-penetrate thickets while displaying clusters
of insect-attracting, white to yellow blooms.
Waiting to be discovered are other members of the
buckthorn family, which are somewhat less easily
spotted than the flowering dogwoods. However, the
buckthorn family is littered with a wide selection of
ecologically and culturally intriguing plants. Many
possess distinctive attributes such as stunning
flowers, succulent fruits, traditional medicines and
unforgiving, ferocious thorns.
Clues for spotting buckthorn members
Of the 900 buckthorn family members worldwide,
Tasmania hosts 23 indigenous members. Helpful
features which can assist bushwalkers to identify
family members include hairy younger leaves and
stems and wrinkled and irregularly surfaced older
leaves. These features are clearly visible in most of
the dogwoods (Pomaderris sp.).
With the buckthorn family being very closely allied
to the grape family (Vitaceae) it is not surprising that
later in summer, bushwalkers will see numerous,
non-edible, grape-like clusters of berries forming on
various dogwood members including the slender
dogwood Pomaderris racemosa. Additionally, it
Land and Coast Care Grant 2016 - Report
MRLC employed an experienced contractor,
Justin Hawkins, to work intensively with several
property owners who had/have significant weed
infestation. Four properties in Mt Rumney Rd.
and two in Grahams Rd. benefited from his
advice and spraying. Justin noted severe
infestations of Spanish heath on the Mt Rumney
properities, including many mature plants.
In Grahams Road he worked on two properities
destroying large swathes of serrated tussock,
again noting many mature plants.
It is unfortunate that in some cases, the weed
infestation is more severe along boundary
fences, thus impinging on neighbours. We
encourage all property owners to inspect their
properities, particularly at the perimeter and
plan to undertake appropriate weed mitigation
action. While MRLC is able to assist with advice,
it remains the responsibility of owners to keep
their land free of invasive weeds and mitigate
‘escapees’ onto their neighbours’ property.

the rusty–brown to grey star-shaped hairs on their
undersides and raised veins.
As for the name 'dogwood', there are a number of
origins3 including a colonially derived name due to
its similarity to the European and American dogwood
genus Cornus. More likely the name comes from the
offensive smell when the leaves are crushed or the
wood is burnt in a camp fire. Hence common
dogwood P. apetala has often been alternatively
called stinkwood
Dogwood’s role in the art of hedge laying
The England tradition of dividing pastures and
properities by hedges was continued in the colonial
Tasmanian countryside, particularly in the north of
the state. Today many thousands of kilometres of
hedgerows divide the farming districts into a mosaic
of pastures and paddocks, with a substantial portion
bordering the roadsides4. Hedges became popular
from the 1820s, and by 1840 parts of the colony
were said to be more English than England!
Although a well-maintained hedgerow is relatively
stock-proof and hence challenging for walkers to get
through, many have become sparse at the base or
tall, leggy and open enough for stock to escape.
Hedgerows are related to the common dogwood in
the following way.
should note that the leaves of some members
can be modified into rather ferocious spines.
Dyes and gentle laxatives
History reveals that a several Rhamnus members
produced yellow-brown dyes used in textiles,
and were distinguished for their abilities to
protect people against witchcraft1 and poisons.
Traditional use of buckthorn barks by American
Indians has resulted in medicinal teas, elixirs or
tablets being extracted from the dried bark and
commonly marketed today as the ‘all-American
laxative’2. They are respected as some of the
gentlest laxatives commercially available. That
said, the dried and granulated bark of the
Tasmanian weed, Italian buckthorn Rhamnus
alaternus, may also relieve constipated bush-
walkers suffering from dehydrated meals.
The ‘Crown-of-thorns’
Many walkers would be aware of the ‘crown of
thorns’! There is a number of Australian species
festooned with sharp thorns including the rare
Tasmanian species, aptly named spiky anchor
plant Discaria pubescens . Luckily from a
bushwalker’s perspective these spiky plants are
scattered along stream banks and stony ridges
without forming thickets like scoparia!
Meet the Australian species
Spotting dogwoods is reasonably easy
Of the 70 Australian species of dogwoods, 10 are
indigenous to Tasmania and as mentioned, are
easy to spot when in flower. They range from low
shrubs in front line coastal habitats such as
coastal bassian dogwood P. oraria, to small trees
found in moist forests such as the narrow-leaf
dogwood P. phylicifolia. Leaves are typified by
Round leaf dogwood
P.elliptica

Hedge laying is the traditional and best way to
maintain hedgerows in a 'working' (stock-proof)
condition and to re-invigorate old and ‘gappy’
hedges. Used predominantly with hawthorn,
‘binders’ were woven through the top of newly laid
hedgerows to securely hold them together.
Traditionally these were made from flexible
greenwood whips such as birch, ash, willow, etc.
However, due to its pliability and rot resilience, the
Tasmanian ‘binders’ were common dogwood.
Pearl-flowers are a special delight
As an aid to taking your mind off those harder
sections of a bushwalk, there are many lesser
known floral gems partially hidden along the sides
of tracks waiting to be recognised or just
appreciated. Justifiably included in this group are
the three pretty Tasmanian small shrubs known as
pearl-flowers. The pretty pearl-flower Cryptandra
amara, which is festooned in early spring with tiny
sweetly-scented white bell flowers, is the most
common of the 40 members found Australia-wide.
Like other herbaceous buckthorns, pearl-flowers
are palatable to grazing cattle, sheep, wallaby and
other marsupials, which prefer their tender foliage
over most other pasture species. Hence they have
limited distribution and are often found in hard-to-
access bushwalking sites.

Dusty-millers, helicopter and propeller bushes
Most walkers would have unknowingly admired
one or more of the eight Tasmanian dusty-millers,
Spyridium species, which would have been seen
thriving in dry, exposed, coastal locations. When
they occur in thickets, with other wind sculptured
coastal heath plants, such as on the coastal side of
the Three Capes Track, this impenetrable scrub
ensures that walkers stay on the track.
Helicopter bush S.vexilliferum var vexilliferum
They are characterised by velvety or prominently-
veined leaves, bold, white, leafy bracts which look
like flower petals, encircling below the tightly-
bunched, insignificant flowers. So prominent are
these white bracts that they look like little
helicopter or propeller blades. The common
names of helicopter bush (Spyridium vexilliferum)
and propeller bush (Stenanthemum pimeleoides)
are rather apt for two fairly common bushes. The
botanical name Spyridium relates to these
characteristic leafy bracts, while the common name
‘dusty-miller’ derives from the dusting of a flour-
like, ashen bloom over the leaves of some species.
From a Tasmanian perspective one of the most
handsome shrubs to be seen on bushwalks is the
endemic velvet dusty-miller S. obovatum var.
velutina with its floral-like, elliptical, hairy upper-
surfaced leaves and compact bunches of
cream/yellow flowers. Found only in dry sunny

rocky areas of eastern Tasmania, they have a lot to
offer the water-wise gardener.

About 60 species of birds live in southern Tasmania.
More than 20 of these have been identified in the
Mt Rumney area including threatened species like
the swift parrot, masked owl and wedge tailed
eagle. Not all of these birds live in the same area all
year round; some migrate to and from Tasmania.
In choosing where they live, birds have three main
needs: a source of their preferred food; a place to
rest and hide from danger and inclement weather
and a safe place to raise their young. Different
species of bird need different types of bush. Intact
bush usually has a full range of vegetation types
from understory grasses and herbaceous plants to
small and tall shrubs and different aged trees
including eucalypts with hollows.
When landowners look at clearing any bushland
they should consider whether it’s really necessary
and how a variety of vegetation types can be
retained. A useful guide landscape planning is the
Property Planning Guide for Landholders from NRM
South www.nrmsouth.org.au.
Native birds need native bushland. All around there
is increasing development. The Mt Rumney area is
fortunate to maintain a large amount of native
vegetation and to enjoy the birds that call that
vegetation home.

Native fauna can consume large numbers of crop and pasture pests. For example, magpies will consume 40 scarab larvae a day.
Insectivorous bats can consume up to half their body weight in invertebrates in a night and some species feed extensively on agricultural pests.

It was nice to see a lone little Wahlenbergia gymnoclada pop its head up in my garden. These delicate little native flowers are named for the Greek gymnos (naked) and clados (branch, shoot) hence the common name ‘naked bluebell’.
Alas, the depicted photo is not from my garden, but a photo of more abundant examples of this pretty little wild flower. (Photo by Keryn Fountain).

Working Bees Although it’s been difficult for some of us to get to the working bees, a small group of keen volunteers have met on a bi-monthly basis to continue weed eradication at the Centauri-Canopus Reserve and along various parts of Mt Rumney Road. We can report that the reserve is now just about free of its burden of Spanish Heath, blackcurrants and briers. We were very happy to welcome some new residents and volunteers to the July working bee and encourage all residents, whether members of MRLC or not, to come along and spend an hour with your neighbours to undertake the various weed projects to be worked on in 2018. No experience needed, just a degree of agility and a willingness to help. The final working bee will take place on Sunday 19th November, starting at 3 pm and concluding with the annual BBQ at 4.30 pm. Please meet at the summit of Mt Rumney to work on Spanish heath and gorse eradication.
Working bees for 2018 will follow the same format as previous years, alternating week days with weekends (using both Saturday and Sunday) to provide opportunities to both us lucky retirees and to the ‘workers’. Working bees will take place as follows • Clean Up Australia Day. Please meet at the
base of Mt Rumney Rd. at 9.45 on Sunday 4 March 2018
• Tuesday 1 May • Saturday 7 July • Tuesday 4 September • Sunday 18 November These dates will be advertised on our website and a reminder send by email at an appropriate time.
Membership renewals Many members renewed their tri-annual membership in July 2015. This is a preliminary reminder that if you are in this situation, your membership runs out on 30th June 2018. We are a small group, so we don’t want to lose anyone; please look out for new membership forms in the first newsletter of 2018 and rejoin our group. Alternatively look for the form on the website, under the membership page.
