All articles for SummerClematis must be in by September 1st.

STATEMENT OF PURPOSE 1. To further the study of natural history in all its branches, promoted by

periodical meetings, field excursions and other activities.

2. To observe and strengthen the laws for the preservation & protection of

indigenous flora and fauna and habitat and important geological features.

3. To promote the formation and preservation of National and State Parks

and Reserves.

It also looks out of place in the Australian bush, being so green, not grey-

green. In its second year each plant flowers and then dies. The inflores-

cences are tall with pendulous branches bearing many pink or red florets.

Along the creek was Kanooka or Water Gum (Tristaniopsis laurina), Sil-

ver Wattle, Forest Nightshade (Solanum prinophyllum), Golden Everlast-

ing (Xerochrysum bracteatum), Wait-a-while or Lawyer-vine (Smilax aus-

tralis) and Common ground-fern (Caloclaena dubia). Kanooka is found

throughout eastern Victoria along streams. It has glossy green leaves and

fragrant yellow flowers similar to those of eucalypts, but the petals are

free and the stamens are united in 5 bundles. Silver Wattle has bipinnate

(feathery) foliage and globular flower-heads in racemes. Forest Night-

shade is a low shrub with lobed leaves with hideous spines arising from

the veins. It has the typical violet potato flowers. Wait-a-while is a vigor-

ous climber which often sprawls across the ground. It is armed with scat-

tered prickles which seem designed to hinder one’s progress, presumably

hence this common name. The common name Lawyer-vine may suggest

that when it gets it’s hooks into you, it doesn’t let go!! Common ground-

fern looks very like Bracken, but the fronds are more delicate and yellow-

green. There was a lemon gilled fungus with a frilled edge; the cap was so

transparent that the gills below could be seen. It was possibly a Mycena.

The road followed a crest with overhead powerlines and the vegetation

below these had been kept slashed. There were many plants of bright pink

Common Heath. There were two adjoining very interesting plants. One

had each of its flowers striped with pink and white down the length of the

flower. Each petal was pink with a white stripe down the centre. On the

other plant the flowers graded from pink at the top to white at the bottom,

somewhat like Fuchsia Heath (Epacris longiflora) which is red and white,

and common in gardens and is native to NSW. A Quail was flushed from

the undergrowth. Another plant in flower was yellow Clustered Everlast-

ing (Chrysocephalum semipapposum). Further along Ash Range Road

was Ploughshare Wattle (Acacia gunnii), a shrub to 1m with assymetric

pointed phyllodes (like ploughshares) and big round flower-heads.

Thank you James for finding interesting plants, even on a cold windy day!

melagramma) with a yellowish-green labellum and Granite Greenhood (P.

tunstallii) with a dark labellum. They are both plants that have no basal

rosette; Tall Greenhood grows to 80cm with up to 20 flowers and Granite

Greenhood is up to 25cm with up to 8 flowers. The flowers are translu-

cent and shiny. The lateral sepals are joined for half their length and end

with triangular, often brown, points. The labellum has a darker central

stripe. The Granite Greenhood is listed as vulnerable, but we found many

more of these than the Tall Greenhood. Nodding Greenhoods (P. nutans)

were just coming into bloom. Spotted Pardalote and White-throated

Treecreeper were heard calling.

We drove along Little Dick Road into an area burnt during the 2007 bush-

fires. At the corner of Beckers Road, the fire had obviously not been too

intense. The overstorey trees were recovering and most of the shrub layer

had been removed. Some of the trees were Yellow Box (Eucalyptus mel-

liodora), Red Ironbark (E. tricarpa) and Mountain Grey Gum (E. cypel-

locarpa). One of the small gums had its trunk heavily indented by a

creeper which had coiled all the way up. The creeper had presumably dis-

appeared during the fires, but a nearby plant was Dusky Coral-pea

(Kennedia rubicunda), a very vigorous climber. The wattle here was Red

Wattle (Acacia silvestris) which has bipinnate leaves and looks very like

Silver Wattle (A. dealbata). Differences?? Pinnules of the leaves of Red

Wattle are mid-green, broadest below the centre, pointed and widely

spaced; those of silver green Silver Wattle have straight sides, blunt tips

and are closer together. A shrub in flower was Sweet Bursaria (Bursaria

spinosa) which as the names suggest has spines on the stem, and fragrant

small white flowers. Another creeper was another pea, the brilliant Purple

Coral-pea (Hardenbergia violacea). Again we found Granite Greenhood,

Nodding Greenhood and Trim Greenhood. White-eared Honeyeaters were

calling.

Up to the top of Mount Little Dick where there is a good view to the ocean

and an old disused wooden fire tower. It was too exposed to have lunch

here on such a cold winter’s day, so along Pound Yard Road we stopped

beside a creek where there was lots of Incense Bush (Calomeria amaran-

thoides) growing. This plant grows vigorously, particularly after fire. It is

a tall (to 3.5m) herbaceous biennial with bright green stem-clasping

leaves. The leaves are thin and sticky, and the plant exudes a strong per-

fume. It looks a little like tobacco, to which it is not related, being a daisy.

BURNT AREAS NORTH OF BRUTHEN - 20 July 2008

by Margaret Regan

From the car park for the Bruthen Walking Trails, we followed the Berry

Farm Loop which is the yellow trail. This is a one hour, 4km walk, to the

north. This area had not been burnt in the 2007 fires which came very

close to the township of Bruthen. It was not the best time of the year to

see plants in flower. In spring some of this area has large patches of or-

chids. There were, of course, Trim Greenhoods (Pterostylis concinna) in

flower. These dainty neat little orchids seem to be blooming on so many

excursions. Although each flower doesn’t exist for very long, Trims are in

flower from May till September. One of the trees was Apple Box

(Eucalyptus bridgesiana). It is a small to medium tree with tessellated

fibrous bark, long tapering adult leaves and stalked fruits with 3-4 exserted

valves. The juvenile leaves are grey-green with no stalks and crinkly mar-

gins. Apparently the wood is hopeless for burning. It seems that this tree

(along with Black Wattles) is important for Sugar Gliders in the winter.

At that time of the year there are few insects about and the Gliders supple-

ment their insect and nectar diet with sap exuded from the trunks of these

trees. Joan’s Dad used to call Apple Box Snotty Box. Perhaps that was

for the sap oozing down the trunk!! The rather sparsely distributed Gold-

en Wattles (Acacia pycnantha) were showing their bright balls. Another

Wattle was Spreading Wattle (A. genistifolia) whose phyllodes have de-

veloped into nasty spines and whose flowers are formed into balls. There

was one plant of a deep pink Common Heath (Epacris impressa). The

small shrub Hop Goodenia (Goodenia ovata) showed a few yellow flow-

ers amongst the bright green toothed leaves. Hop Goodenia is often found

along the disturbed edges of roads. Except for one species in Malaysia, all

the other 120 species of Goodenia are Australian endemics (i.e. they only

grow in Australia), of which 22 are Victorian. We also found the endan-

gered Bushy Hedgehog Grass (Echinopogon caespitosus) whose inflo-

rescence is more open than that of the Common Hedgehog Grass (E.

ovatus). We have seen this endangered Hedgehog Grass before at Swal-

low Lagoon. There were some tiny specimens of the bracket Rainbow

Fungus (Trametes versicolor) along a fallen branch. These were velvet

browns in concentric bands on the upper surface with a white edge and

mushroom-coloured beneath. Another bracket was thin and layered or-

ange above, but with grey-green layering below. We saw quite a few

specimens of two very similar greenhoods: Tall Greenhood (Pterostylis

shrub has very narrow leaves and the cones when mature are covered with

bright orange-black hairpin styles. They were in magnificent condition

with many fresh cones which the Crescent Honeyeaters were loudly enjoy-

ing. We searched and found the specific fungus which grows on the old

shed cones of this banksia. This cup fungus Large Banksia Cup

(Banksiamyces macrocarpus) is blue and the cups grow out in between the

seed follicles. There was also Silver Banksia (Banksia marginata), anoth-

er shrub whose leaves may be entire or serrated and have cut-off or

notched tips; Myrtle Wattle (Acacia myrtifolia) with phyllodes with thick-

ened margins and flowers in balls in small racemes; and Juniper Wattle

(Acacia ulicifolia) with needle-like phyllodes with stipules and single balls

of flowers. There were two coral fungi, one a mushroom pink and the oth-

er pale yellow.

We were distressed to drive along Prices Break and see the damage creat-

ed by a bulldozer driver making enormous drains at very close intervals

destroying vegetation. Surely a smaller drain would have been sufficient

to control the run-off. This sort of damage appears to be very common

this year. Apparently further east a patch of the rare Nowa Nowa Grevil-

lea (Grevillea celata) had been removed by such rampant bulldozing!!

We went to marvel at the old disused Nowa Nowa rail trestle bridge over

Stoney Creek. Built in the early 1900s it is 276m long and 19m high.

Back to Corduroy Rd to see Pelicans or the Small Helmet-orchid Corybas

in the upper half and the labellum tubular with the margins incurved.

Thank you once again James.

istifolia) was in bud and most unpleasant it was too - poking one painfully

all the time. It has spiny phyllodes with the flowers in globular heads 2-4

per axil. They are both small, open shrubs.

Down Quarry Road we took the path to the old Quarry. On the way we

heard Bell Miners and Yellow Robin. Scarlet Bracket Fungus

(Pycnoporus coccineus) was found on a small dead branch. The quarry

which supplied stone for maintaining the entrance to the Gippsland Lakes

has been given a tourist upgrade. At the site are information boards about

the uses of the rock from the quarry. The granite was transported 13 km to

North Arm on a tramway travelling beside Mississippi Creek. Part of the

display is a set of two wheels from a trolley set onto some 3’6’’ gauge

rails. The granite was then used either as rocks at the entrance or crushed

to make concrete. The tramway was opened in 1910 and was used until

the mid 1930s. The original entrance to the lakes was partly constructed

with timber and this was destroyed by toredo worm. The stone from the

quarry was used for repairs. The granite was also used for other projects

in Lakes Entrance and in Melbourne.

We strolled along the tramway track beside Mississippi Creek and found a

large brown cup fungus about 10cm across, which may have been a Pezi-

za. The Small Rooting Shank is a gilled fungus with a long white stalk

and gills, and a mid-brown shiny cap. There was a fawn coral fungus just

erupting through the soil, and the gilled fungus we call Pizza Cap

(Amanita xanthocephala) whose orange cap bears the remnants of the veil

which covered it in the button stage. We listened to a wonderful Superb

Lyrebird imitating Yellow-tailed Black-cockatoo, Eastern Whipbird, Grey

Shrike-thrush, Crimson Rosella, and Red and Little Wattlebird. There

were Fringed Helmet-orchids (Corybas fimbriatus) with laidback or re-

clining flowers!! The circular labellum has deeply fringed margins. The

surface of the ground was moist so that all the mosses, liverworts and li-

chens were hydrated and bright, but the lyrebird scratchings showed us

that just beneath was dry, dry!! We saw the common satiny Coltricia cin-

namomea woody pore-fungus which has a round brown upturned cap with

a white rim. Along part of the track near the quarry the cutting revealed

limestone with embedded shells.

On to Siberia Crossing Road to one of our favourite sites to see the small

patch of isolated plants of Hairpin Banksia (Banksia spinulosa). This

PRESIDENT’S MESSAGE

In 2007 our Club responded to the enthusiasm of members like Jen

Wilkinson, Andrew Bould and Pauline Stewart to showcase the

beauty and diversity of the flora and fauna of East Gippsland

through the medium of a quality full colour calendar. Having made

the decision to proceed, the search was on for a seeding grant which

we eventually obtained from the East Gippsland Catchment Man-

agement Authority under its Regional Catchment Investment Plan.

The 2008 calendar was highly acclaimed and 424 copies were sold

which has enabled us to produce the 2009 calendar and thus far ful-

fill our intention to make it an annual self funding calendar

There are 2 separate functions associated with a calendar- first, de-

veloping the calendar and second, marketing it. On both counts we

are very much on a learning curve.

For example, this time we have been much more rigorous in our

specifications to subscribing photographers and have reduced the

size. We have increased the print run from 500 to 750.

From a marketing perspective, we took the advice of retailers to re-

duce the price from $15 to $12. We have it ready for sale much ear-

lier, and it is packaged more conveniently in lots of 20. We have

placed them in commercial enterprises where they sold well last

year.

Now it is time to say thank you.

Thank you first and foremost to Jen Wilkinson who has car-

ried most of the production effort this year and to Pauline

Stewart for her participation in the early part of production

Thank you to the photographers who submitted photos and

to those whose excellence in photography has been rewarded

by inclusion in the calendar

Thank you to Andrew Bould and James Turner for their edit-

ing and input in the latter stage of production

Thank you to Pauline Stewart who is co-ordinating the mar-

keting of the calendar

Thank you to Margaret Regan who juggles the many finan-

cial transactions associated with the calendar

Thank you in anticipation to all members of the Club whom

I am sure will buy up big again this year.

It was my pleasant duty to launch the beautiful Bairnsdale and Dis-

trict Field Naturalists Club calendar for 2009 at a general meeting

on 19th September.

SUMMARY OF REPORT ON SMOKY MOUSE FIELD TRIPS

April 5-8 and April 10-12, 2008

by Jenny Edwards

These field trips were conducted by Jenny Edwards of Gippsland High

Country Tours, Bruthen (Research permit No. 10004063) in conjunction

with volunteers from Bairnsdale & District Field Naturalists Club. Both

field trips were funded by a Commonwealth Envirofund grant to conduct

searches for Smoky Mouse colonies in the Cobberas area. This article is a

summary only, the full report is available on request.

Aims for these two visits were primarily to-

Search for new Smoky Mouse colonies in the Cobberas area using

a variety of methods.

Determine whether the existing colony near Native Dog Flat ex-

tends beyond the perimeters already recorded.

Investigate potential sites in the Cobberas area for future survey

work,

Record site characteristics and vegetation for all survey sites.

Record all wildlife species encountered during the visits on the

Atlas of Victorian Wildlife Database.

If any Smoky Mice are captured -

COLQUHUON FOREST - 22 June 2008

by Margaret Regan

We met near the corner of the Princes Highway and Bruces Track. On a

wander close by we found in bloom, Nodding Greenhood (Pterostylis nu-

tans), Trim Greenhood (P. concinna) and Mosquito Orchid (Acianthus

exsertus). Unfortunately there was also the odd flying relation of the last-

named, even though it was a very cold day. There was a tiny (3mm) pale

yellow gilled fungus with a long stalk growing in the midst of a clump of

the bright green moss Thuidium. A little further north along Bruces Track

in the bush we saw, beneath the overstorey of White Stringybark

(Eucalyptus globoidea) and Blue Box (E. bauerana), Cranberry Heath

(Astroloma humifusum) with bright red tubular flowers, and Common

Heath (Epacris impressa) whose tubular flowers ranged in colour from

pale to medium to deep pink. We also found Woolly Grevillea (Grevillea

lanigera) with its cream and red flowers. There were again Trim Green-

hoods and the stunning large-flowered Cobra Greenhoods (P. grandiflora)

where the petals making up the hood with the dorsal sepal, are brown and

flared out horizontally. Another orchid was Spurred Helmet-orchid

(Corybas aconitiflorus) which had a spur on the stem below the flower.

The Helmet-orchids have a curved hooded dorsal sepal enclosing the flow-

er. The Spurred Helmet-orchid has a heart-shaped leaf which is green

above and purple beneath. The species name of this orchid arises from its

resemblance to Monkshood (Aconitum), an introduced perennial garden

plant. On a dead branch were a number of the hairy cream fungus Split

Gill (Schizophyllum commune). It has a lateral stem and the gills are each

divided into two. Growing in amongst another moss called Bryum was

this time, a minute yellow disc-shaped cup fungus which may have been

Yellow Earth Buttons (Discinella terrestris). Some puffball fungi were

Earth Stars. These have two layers, the outer of which splits open like a

star, and the inner thin papery layer has a tiny pore at the top through

which the spores are released. It is very difficult to resist puffing one!!

There was an large ants’ nest, about 60cm across and 20cm high made up

of tiny sticks. We heard a White-throated Treecreeper giving a variety of

calls, and one was even tame enough to climb a tree quite close to two of

us. They are a very striking bird, close up, with bold black and white scal-

lops on their breasts below the white throat. Even further up the track

Sweet Wattle (Acacia suaveolens) made a very pretty sight. It has long

thin phyllodes and flowers in clusters of balls. Spreading Wattle (A. gen-

Collect Smoky Mouse scats for diet study

The study area is located in the East Alps Unit of the Alpine National Park

on the Suggan Buggan 1:50,000 Mapsheet 8524-S. The Alpine Fire 2003,

burnt through this entire area although the burn intensity varies greatly

from intense hot burns, through slower understorey burns to unburnt

patches.

Summary of methods used

The only site within the Cobberas area and in fact within the entire East

Alps Unit of the Alpine National Park where live Smoky Mice have been

trapped is the Native Dog Flat site. The only other record (Atlas of Victo-

ria) is a record of a dead Smoky Mouse found near Native Cat Track in

1974.

Although there has been much discussion about what constitutes ideal

Smoky Mouse habitat and it is generally agreed that they do require a di-

verse heathy understorey, there is little to help determine where are the

best places to search for Smoky Mice. It appears that they may prefer a

habitat where fire has been excluded for many years. From records in oth-

er areas, it seems that Smoky Mouse populations experience unexplained

fluctuations possibly due to resource availability or predation

It was not possible to search the entire study area on these two short field

trips, so the aim was to select the more likely sites for Smoky Mouse and

to include them in the searches.

A habitat modelling exercise was conducted in which a list of the 11 most

commonly recorded plant species found at the successful capture sites

were used to represent the “ideal” Smoky Mouse habitat and fed into Flora

Information System (FIS). The best match that occurred in the Study Area

was one quadrat with 6 of the plant species present and one just outside

the study area which was also included.

Given the size of the area to be searched large scale live trapping was

considered unsuitable in terms of effort required as well as in terms of the

large by-catch of non-target species that would be captured. The use of

hair tubes requires less effort, but the success of gathering Smoky Mouse

hair samples with hair tubes, seems to vary considerably with the hair tube

design.

Predator scat analysis was decided upon as the preferred large scale meth-

od to search for evidence of Smoky Mice across the study area. This

method is totally non-invasive and the aim was to collect scats over a

number of vehicular or walking tracks in the study area..

Prospective survey sites was selected using the following criteria-

General wildlife observations

In addition to the wildlife species recorded through trapping, hair tubes and preda-

ened species to the list. At Square Flat, abundant scat of Broad-toothed Rat was

observed on runways in the heath and an animal was observed out basking. In

addition a dead Alpine Water Skink was discovered.

Discussion

The single capture of a tagged Smoky Mouse on the “lower West Bank” transect

at Native Dog Flat demonstrates an extension of a known site rather than the dis-

covery of a new site. It clearly shows that the river is no barrier, with ample

“steppingstone” providing access across the water. The vegetation in which this

Smoky Mouse was trapped is hardly typical, consisting of a small patch of wet

heathland vegetation right on the river bank. Consistently, however it has been

unburnt for a considerable time with very old heath plants.

While no Smoky Mouse hairs were found during trapping a new site, in hair

tubes/funnels or in predator scats, it is early days post-fire and vegetation is still in

fairly early stages. We did identify further potential habitat including some un-

burnt/lightly burnt sites.

Captures of good numbers of Bush Rats and Agile Antechinus at the Rams Horn

Track site show good post-fire recovery of these species in lightly burnt habitat

and hair tube transect results show that they have also returned in habitat that was

burnt at high intensity over an extensive area 5 years previously.

Further analysis of results are in the full report.

Recommendation

Although no new Smoky Mouse sites were recorded a lot of valuable data was

collected on habitat and on other small mammal species. Potential future survey

sites were identified and it would be very productive to consider applying for an-

other grant to conduct a similar exercise in future years.

Twelve were collected from approx 6km of Forlorn Hope Track from the Black

Mountain Road to the Buchan River (passing the site identified during habitat

modelling). Eight were dog scats, 3 were fox and one a possible fox. Prey in-

cluded Rabbit, Common Wombat, Brushtail Possum, Bush Rat, and Eastern Pyg-

my Possum.

Fifteen were collected along approx 3km Sugarloaf Track from Wombargo Track

to just north of a site identified through Smoky Mouse habitat modelling. Twelve

were dog scats and three were fox. Prey included Rabbit, Brush-tail possum spe-

cies, Common Wombat, Black Wallaby, Common Ringtail Possum, and Agile

Antechinus.

In addition to confirming the presence of Dog and Fox, the predator scat analysis

confirmed the presence of eleven other mammal species and although the sample

size is small, provides an interesting snapshot of preferred/available prey for each

predator.

** Elliot traps were set adjacent to the current known colony of Smoky Mice

(Native Dog Flat site) to satisfy the aim of determining whether this site extends

beyond the current known perimeters.

Elliott Trapping

Elliott Traps were used in two trap transects (20 traps each) over each of the two

visits. One transect along Rams Horn Track and one along the west bank of the

Buchan River opposite the known Smoky Mouse site. Clean traps were baited

with peanut butter, rolled oats and honey bait plus freshly broken pieces of

walnut. Dacron was placed in every trap for warmth and each trap was inserted

into a plastic cover to offer protection from cold and rain. Traps which captured

an animal were replaced with clean traps for the next night. April 5-8 they were

set for 3 nights and April 10-12, just 2 nights. Thank you to Parks Victoria at

Omeo and Heyfield for the use of Elliott traps for this survey.

One Smoky Mouse (P. fumeus) was captured in the last trap checked on the last

day of the second field trip on the lower West Bank trap line at Native Dog Flat.

This was a tagged animal, number 955 which is a mature male first captured in

the main trapping grid as a mature male in December 2007 approx 60m from this

trap and at a higher altitude (approx 30m higher) on the opposite side of the river.

Smoky Mouse scats were collected from the trap after processing and stored in a

sealed container then dried and frozen prior to being sent to Dr Fred Ford

(CSIRO). The analysis of these scats will help to determine the identity of plant

and seed remains in the scats and therefore important food plants.

Non-target species captured in traps at the two West Bank, Native Dog Flat tran-

sects were 3 sub-adult Agile Antechinus (Antechinus agilis). Non-target species

captured in traps at the two Rams Horn transects were 11 juvenile & sub-adult

Bush Rats (R. fuscipes) 4 of which were subsequently recaptured and 5 sub-adult

Agile Antechinus (Antechinus agilis), 2 of which were subsequently re-captured.

Hair Tubes and Funnels

The hair tube transect along Native Cat Track extended (north and south) along

the track from a point close to the historic Smoky Mouse site. Although intensely

burnt in the 2003 fire, the post fire regeneration is quite dense.

Two different designs of hair tubes (home made poly hair tubes and commercial

Fauna Tech hair funnels) were used alternatively in each transect along Native

Cat Track. Hair tubes were baited with the same bait as Elliott traps and mostly

placed alongside logs or stumps.

Three 220m transects of hair tubes and funnels were set out over the two field

trips consisting of 40 hair tubes/funnels. The two different designs were set alter-

natively in parallel lines on each side of Native Cat Track. In total these were set

for 360 hair tube/funnel nights covering both sides of 660m of track.

A total of 34 hair tubes/funnels had hair or hair-like material adhering to the

tapes/wafers or scats within the hair tube or funnel. These were all sent to Barba-

ra Triggs for analysis.

Predator Scat Collection

Predator scats were collected in the vicinity of the Native Dog Flat trapping sites

and along 4 vehicular and walking tracks which were systematically searched

during the field trips. Sixty-one predator scats were collected in total. All were

sent to Barbara Triggs for analysis of both predator and prey.

Five were collected from Native Dog Flat camping area and the vicinity of the

Native Dog Flat Smoky Mouse site. Four of these were consistent with Quoll scat,

but no groom hairs were present, the other was possibly a dog scat. Prey were

Common Wombat, Agile Antechinus, Bush Rat, Brushtail possum sp. and Eastern

Pygmy Possum.

Seventeen scats were collected along approx 2.5km of Native Cat Track from

Black Mountain Road south to just south of the historic Smoky Mouse site.

Twelve were dog scats and 4 were fox, plus one probably fox. Prey included

common Wombat, Dog (as prey), Common Ringtail Possum, Eastern Pygmy pos-

sum, Common ringtail Possum, Black Wallaby, Brushtail Possum sp. and Rabbit.

Twelve scats were collected from along the full length (approx 4km) of Rams

Horn Track including two from a gully just off the track and one from the rocks at

the summit. Seven were fox scats, four were dog and one possibly quoll. Prey

included House Mouse, Rabbit, Common Wombat, Grey Kangaroo, Dusky Ante-

chinus and Brushtail Possum sp.
