Tuesday 15 March 6.00 pm Barry Drive, Acton ACT
All financial members of FOG are invited to our Annual General Meeting on Tuesday 15 March at 6 pm at the Conservation Council offices, 26 Barry Drive, Acton ACT.
Come for 5.30 pm so you can catch up with other members beforehand! Afterwards we expect that all or some of us will go to dinner at one of the nearby restaurants.
The agenda for the AGM is included with this newsletter. Please bring it to the meeting.
Members may submit motions to be put to the meeting, and must then attend the meeting in person to speak to the motion.
Any financial member of FOG may nominate office bearers and committee members, either before the AGM, in writing – accompanied by written confirmation from the nominee that they accept the nomination – or at the meeting itself.
A very important part of this year’s AGM will be the nomination and election of a new President, because Sarah Sharp has declared herself unavailable for the role in 2016. (See page 3 for a summary of the President’s role in FOG.)
Motions, valid written nominations and any apologies must reach the Secretary before Sunday 13 March to be included in the meeting.
See you at the AGM!

Grassland invertebrates, Saturday 5 March
Come and join Kim Pullen, keen entomologist and long-time FOG committee member, as we look for small grassland fauna at Yarramundi Reach grassland, 10 am till noon.
We will aim to use nets to catch, tweezers to hold, and hand-lenses to identify, insects and possibly other invertertebrates in that grassland. No fauna or people should be harmed in this venture.
Meet: 9.55 am at the carpark at the ATSIC Cultural Centre, 245 Lady Denman Drive, ACT.
outdoor gear, solid footwear and sun protection.
Bring drinking water, and hand lenses if you have them.
Please email email@example.com to say you are coming.
Workparties to support native biodiversity, Sunday 28 February – Stirling Park 9.30 am – 12.30 pm
Our tasks: Cutting and daubing the last woody weeds left at the north end of Stirling Park ridge, and dealing with the heavy weedy growth around the spring. We may also be watering our plantings at the south end, and collecting rubbish.
Meet in Stirling Park, across Alexandrina Drive from the rusty DNA sculpture car park, about half-way between Mariner Place and Hopetoun Crescent. Look for the Friends of Grasslands signs.
Wear gardening clothes and solid footwear, and bring drinking water, sun protection and eye protection.
Contact Jamie.firstname.lastname@example.org or 0407 265 131 if you intend to come, so there are enough tools and morning tea.
Hot weather: The workparty will automatically be cancelled if the weather forecast the night before is for 35oC or more, or it is a total fire ban day. If the forecast is for more than 30oC the workparty may stop earlier than scheduled.
Saturdays 12 March & 2 April – Hall Cemetery, 9 – 11 am
These autumn work mornings are to continue our control of fleshy weeds, especially emerging thistles, and also of selected patches of exotic grass. The major action will be spot application of herbicide through the grassy woodland. Some physical removal can also be done. Morning tea is provided. Please dress for the weather and tall grass.
MOST IMPORTANT – so that enough gear (and morning tea) is on hand to match the enthusiasm of volunteers, REGISTER at least two days in advance, with email@example.com.
For other events see page 2.
Canberra Heritage Festival activities, April
1. ‘Discover our natural treasures’ – four events run by the Conservation Council ACT region
Discover Kama: Tuesday 5 April 7.30 am, Kama Nature Reserve
One of this year’s Canberra Heritage Festival activities is a walk organised by the Conservation Council ACT Region in Kama Nature Reserve.
The walk will last about 2 hours, starting early (7.30 am), and will follow established tracks, with the walkers in small groups (up to 10 people). Group leaders will include FOG members Kat Ng and David Johnson with John Fitz Gerald, as well as members of Canberra Ornithologists Group.
FOG will have Woodland Flora available for sale at this event ($20 for FOG members; $25 for others).
Kama is in the Belconnen region, on the north-east side of the Molonglo River. David Johnson is doing experimental work on forbs in this grassland, as part of his PhD studies at ANU Fenner School. The area offers plenty of plants of interest, including Themeda triandra, and lovely old trees and nest hollows and woody debris; it is moderately weedy in places. We hope the birds will be active early on this morning.
IMPORTANT: This activity will take only 20 people. If you are interested in attending, please register your interest with firstname.lastname@example.org before Easter. John will contact us at the end of March to let us know if there are enough places available for us to join in.
Discover three other natural treasures in ACT
The Conservation Council is also offering the chance to explore aspects of the nature reserves at Mulligans Flat (9 April,10 am), Kinlyside (14 April,10 am) and Red Hill (17 April,10 am).
2. ‘Discovering a forgotten woodland & rediscovering Ngunawal culture’ – run by Molonglo Catchment Group
Field day & barbecue: Saturday 9 April 9.30 – 12.30, Stirling Park (Block 2 Section 128 Yarralumla – opposite Canberra Yacht Club and Lake Burley Griffin)
Celebrate Ngunawal caring for country and local Landcare Living history, as told by a remnant corner of woodland, a tiny Button Wrinklewort plant and a Ngunawal family who camped on a creek on the side of present-day Capital Hill before the building of Canberra.
3. Callum Brae Nature Reserve – an event run by Greening Australia
Callum Brae Nature Reserve: Saturday 2 April.
Details to come.
More information will be available about these and other events on the website, http://www.environment.act.gov.au/heritage/heritage-and-the-community/heritage_festival or through the organisations running the activities.
Managing your land for the future: resilience and adaptation for climate change Friday 18 – Saturday 19 March
In the upper Murrumbidgee catchment the climate is changing. Temperature records are regularly broken, seasonal climate patterns are moving and extremes of drought and flood are predicted. Those living on the land or managing land and water resources are dealing with the changes on a daily basis. Managing for adaptation and resilience is essential.
Join land managers, science, government and industry at this forum at Murrumbateman NSW (18 March) and Queanbeyan NSW (19 March), to hear key speakers in the mornings and go on field trips in the afternoons. The forum is run by the Upper Murrumbidgeee Catchment Coordinating Committee.
Book: Eventbrite > UMCCC forum.
Cost: $50 for both days or $30 for one day, all inclusive.
Program and details: www.umccc.org.au.
National Seed Science Forum 14–16 March , Mt Annan NSW
Forum registration closes on Monday 29 February
Forum on next generation environment laws, Thursday 24 March, 12 – 2 pm
A public forum reviewing the way nature, wildlife and people are cared for in Australia to see where protection of nature can be improved. One of several being held across Australia.
Place: Alan Barton Forum, ANU College Business & Economics, Kingsley St, Acton ACT.
Details & registration: http://conservationcouncil.org.au (scroll down to Upcoming Events, righthand side of the screen).
Community planting at Queanbeyan, Sunday 1 May 9.00 – 12.00
We are invited to help the Molonglo Catchment Group and its members with this planting activity for the Stringybark/Environa Biodiversity Connectivity Project. The project is a consequence of recent environmental offsets related to planned roadworks near Queanbeyan.
Meet at the corner of Bicentennial Drive and Balcombe Street, Jerrabombera Park.
Wear gardening clothes and sun protection and bring gloves.

Maree Gilbert, of Kambah ACT
Friends of Yass Gorge, of Yass NSW
Dr Ken Hodgkinson, of Evatt ACT
Michelle Storey, of Gundaroo NSW.
ActewAGL released a Vegetation Management Consultation Paper for public comment. FOG was concerned about the impact of the proposed significant increase in minimum clearance distances around electrical infrastructure occurring in the Bushfire Abatement Zone, and urged that smaller clearance distances be used in high conservation value areas or areas supporting threatened species.
FOG supported TAMS’s proposed nature strip guidelines as long as there is no increase in nutrients or an increase of organic matter entering the drainage system. It also recommended the addition of some more native plants to the list of recommended plants in the guidelines.
The full text of FOG submissions appears on our website.
If you find a renewal form with this newsletter, your renewal has not yet reached our records. Renewals are due on 1 January for the calendar year.
FOG members receive earliest notice of FOG activities, including: visits to grassland and grassy woodland areas with expert guides; mornings restoring grassy areas and chatting over morning tea (which FOG provides); the mid-winter afternoon of talks and ‘slides’; the end-of-year picnic in December; and the AGM in March. FOG members can join FOG’s subgroups, such as for advocacy. Members get the newsletter promptly as soon as it is published, every two months (it’s two months old when it reaches the website).
As indicated on page 1, Sarah is standing down as President. The current committee is therefore calling for nominations for this role, and also invites other FOG members to join us on the committee. Some information is provided here to help you decide if you would like to join us. We would love it if you did!
The rules state that the president will:
1. Chair AGM, committee meetings, and other meetings of FOG, and oversee the preparation of agenda and minutes for formal meetings. (Note that some of these duties may be delegated.)
2. Act as spokesperson for FOG, represent FOG at meetings/forums, and sign correspondence and submissions (may be delegated).
3. Ensure that the committee and activities of FOG are effective, that the newsletter/eBulletin, program, correspondence and submissions are done to a high standard and consistent with FOG’s objectives, values and policies (shared with the committee).
4. Show leadership, encourage membership participation, and seek decision making with respect and by consensus wherever possible. Show respect for the views and opinions of all (potential) stakeholders (shared with the committee).
In other words, the President has an overseeing role for all of FOG’s activities, liaisons and memberships, with some representation and follow-ups shared with other committee members. Other tasks/roles can be filled by the President or delegated to other committee members, including representing FOG at meetings or in other fora with other groups and government, depending on interests, time and expertise.
We welcome anyone to consider joining us on the committee, to become more involved in the many sides of FOG. We especially would love to welcome someone with the skills listed above who would consider nominating for President. You certainly don’t need to be knowledgeable about the ecology of grassy ecosystems; just someone with the skills to direct the group.
Please email Sarah on email@example.com to discuss this further. For more information on how the committee and the FOG organisation works, go to the website, http://www.fog.org.au/statement.pdf.
Between 2000 and 2012, FOG used to undertake working bees to control weeds at Old Cooma Common Grassland Reserve (OCCGR) in southern NSW. Although our work ceased several years ago, we are reluctant to see the condition of OCCGR deteriorate to the level of most of the surrounding countryside, with ever-encroaching St John’s Wort (SJW) (Hypericum perforatum) and African Lovegrass (ALG) (Eragrostis curvula), especially given their threat to the populations of the Monaro Golden Daisy (MGD) (Rutidosis leiolepis) that grow at OCCGR and two nearby sites.
We therefore sought grant funding to pay contractors to continue our earlier fight against the weeds.
As reported briefly in the January–February 2016 News of Friends of Grasslands, FOG has recently secured a $32,000 grant from NSW Local Land Services (LLS) to cover various weed reduction activities on OCCGR, on Crown Land to the north of the Common, and on the Firing Range over the road to the south of the Common. The grant runs for three years, from late 2015 to late 2018. Populations of the MGD grow at all three sites, within natural grassland, but they are threatened by invading weeds, especially SJW and ALG. (The photo, courtesy of Cooma-Monaro Shire Council, shows signs at OCCGR.)
We aim to contract-out spraying of SJW and ALG; to monitor the weed populations and MGD annually; and to conduct three field days. We intend to undertake best practice weed management for these weeds and to document and communicate the results. Our results will be demonstrated at the field days and published in reports to LLS, in the FOG newsletter and in the Cooma print media.
Like all grant applications, the securing of the grant took some time, with several levels of applications involving a number of people. The satisfying news that we had been successful with our application came in September 2015, although there were still some documents to prepare after that. This project involves a high degree of cooperative work. Luke Pope of the LLS and Brett Jones of Cooma-Monaro Shire Council will provide on-going assistance with organising and liaising with contractors for the spraying, and with conducting the field days later on.
We began the monitoring program before the start of the weed control, and mapped the populations of the MGD. The monitoring methods were developed with Rainer Rehwinkel to be consistent with those used by NSW Office of Environment and Heritage for monitoring weeds and threatened species. The monitoring will be repeated every year at the same time.
The initial monitoring was done in early January 2016. Three transects on the Common (SJW x 2 and MGD x 1) and three on the Firing Range (SJW x 1, MGD x 1 and ALG x 1) were established and measured. When surveying the northern Crown Land site we saw very little obvious MGD or SJW, but that site has been continually grazed for many years, which may account for the difficulty in locating our target species. Another visit will be paid to the site at a more promising time.
In the second week of February, this year’s spraying began. For best practice, our main concern is to take care to prevent overspraying, and also to ensure all the weeds are treated. I have discussed our strategy with the contractors, and explained that we would like them to pursue the SJW and ALG from a closer range than they may normally do things. They know that we realise the job will take longer if this care is taken, thus costing more, but we wish to demonstrate that better outcomes will be achieved as a result. We shall spend nearly half of the total spraying budget in this first year in an attempt to hit the SJW and ALG hard, prioritising the areas where the MGD is present. The amounts spent on contractors will be reduced in each of the following years, as fewer weeds recover. Our aim is to demonstrate the outcomes against the budget, enabling a cost-benefit analysis – the benefit being protection of the threatened species and other grassland flora, and significant reduction in the threatening weeds.
Once we have something to communicate to the world, we shall conduct our first field day.
We still have a long way to go with this project, and we would love to hear from FOG members who would like to be involved with future monitoring and field days.
No specific skills are required, just a wish to be part of an enthusiastic team of fellow volunteers. Please contact me (mob. 0427 788 304).

Our four work mornings during 2015 in the grassy woodland block surrounding Hall Cemetery have involved in total around 70 volunteer-hours. Continuing the trend of recent years, little effort has been needed for large woody weeds: a few tenacious Briar Roses and Hawthorns were the exceptions. Instead, control has focused on fleshy weeds including various Thistles, Plantain, Cleavers and Capeweed, via both physical removal and application of herbicide. The persistence of the Cleavers is particularly annoying.
In addition we have further pushed back the areas of exotic grasses by attacks on Phalaris, Perennial Rye and Tall Fescue, but this is a big job. The exotic grass flowering was huge in 2015, including the species above together with Yorkshire Fog, Giant Brome and Sweet Vernal, so a lot of new germination is likely in future years.
We regularly maintain the areas under our steadily growing Bursarias (e.g. photo at left), to keep the groundcover low.
Hall Cemetery has become one of the sites specified in the fantastic Canberra Nature Map website and mobile phone app. By mid-Feb 2016, over 88 sightings of species of native plants, fungi, birds, frogs and reptiles were listed for this location ... and spiders and insects including moths were yet to be added!
Braving the heat of summer, FOG volunteers have been hard at work in the past two months restoring Stirling Park. In late December, a sturdy band of people watered the trees planted over the last two years, to ensure that they survived the limited rain until that point. A few volunteers returned a few days later to cut & daub and spray weeds missed in previous efforts on the western and northern ends of the ridge. In particular, St John’s Wort outliers were targeted for spraying.
On 31 January, 13 FOG volunteers gathered at Attunga Point on the shores of Lake Burley Griffin to re-weed this important site for Button Wrinklewort Rutidosis leptorrhynchoides. FOG weeded this site in 2009, and it was pleasing to see how little the fenced area had been re-infested in the intervening years. We were able to push out the boundary of the weeded area to cover the disturbed land between Attunga Point and the main area of Stirling Park. A veneer of weed trees along the shoreline of the lake await sufficient funding for their safe removal. Our enthusiastic labour also enabled removal of the modest weed regrowth in some previously worked areas of the adjacent area of Stirling Park.
We are making great progress in removing woody weeds at Stirling Park and hope to complete the first cut-over of the area at the workparty on 28 February. Sadly it has been bountiful growing season for African Lovegrass, Blackberry and St John’s Wort, and further effort is needed by land managers to spray these weeds.
Three FOG representatives met with Malcolm Snow, Chief Executive, and Peter Beutel, Manager of the National Estate for the National Capital Authority (NCA), on 9 February to discuss the conservation of ecologically significant national lands. The NCA has provided a further, and welcome, $6000 in 2016 to support FOG’s conservation activities on national lands. FOG welcomes the NCA’s ongoing management activities, including a timely revision of the 2009 ecological management plan for these lands. Priorities for future environmental work were discussed. FOG also expressed its concern that the recent revision of the National Capital Plan failed to improve the protection afforded the natural heritage values of these lands despite FOG’s submission. The NCA officers explained the Authority’s intention to undertake a further, finer-scale planning process in 2016 which would consider development controls at Stirling Park.
In January, FOG also acquitted a $6000 grant for 2014–15 from the ACT Regional Delivery of the National Landcare Program administered by the ACT Environment and Planning Directorate, titled ‘Restoration of Grassy Ecosystems and Endangered Species Habitat in Central Canberra’. These funds enabled FOG to significantly enhance weed control and revegetate strategic areas at Yarramundi Reach and Stirling Park. Monitoring at Yarramundi Reach and Stirling Park shows an ongoing reduction in woody weed cover but mixed results for herbaceous weeds. FOG contributed nearly $21,000 in volunteer labour to the project; nearly $50,000 was contributed in management activities by the NCA and Rural Fire Service. FOG thanks the ACT Environment and Planning Directorate for their strategic support.
On a warm lazy-feeling Monday afternoon in late summer, 18 members and friends of grasslands, accompanied by one very small well-behaved lass in-arms, assembled at Croke Place to visit the grassland restoration trial run by Dr Ken Hodgkinson with the North Belconnen Landcare Group.
In the shady carpark, Ken gave us a short introduction to the aims of the trial and the burning and mowing treatments (and reseeding, til that was made inviable by drought). Then we walked along the path towards the Lake Ginninderra dam wall, turning off before reaching it. There, running up the slope between an old track (now rich in weed grasses) and William Webb Drive, we found posts marking five very different rectangles of native grassland. These plots (Ken is pointing them out in the photo, left), originated around 8 years ago as a demonstration, but Ken is now measuring the treatment effects. You can read about the trial and the results to the end of 2014 in Ken’s spoken presentation published at www.fog.org.au > forum proceedings.
The plots are astonishingly different. Ken sent us all off to walk along the plot boundaries (photo, right) to see if we could identify which treatment had been applied to each plot. That was not an easy task, I found!
The no-treatment plot looked overfull, with thick vegetation above knee-high. The autumn-burn plot and low-mow plot were the best looking, and the spring-burn and high-mow plots looked in intermediate condition – at this visit, anyway. There was Kangaroo Grass Themeda triandra in flower in both the burnt plots, while the low-mow (as low as possible) and high-mow (to ~15 cm above ground) plots were green.
Ken said that his aim ultimately was to find a way to restore Canberra’s grasslands to high floristic richness, with many different flora species – so people can enjoy them. Apparently this trial is succeeding in doing that because he is finding most native forbs – such as Blue Devils Eryngium ovinum, Bulbine Lilies Bulbine bulbosa and native Plantain Plantago varia in the autumn-burnt plot. It also has fewest weeds, especially uplope – some Vulpia, Briza minor and Avena fatua Wild Oats. Some of the native forbs in the burnt plots are not found at all in the mown or control plots, and would probably die out here if there was no burning being done.
Karissa Preuss, Landcare Coordinator for Ginninderra Catchment Group (GCG) (the plots are close to Ginninderra Creek), explained to the group that this trial was the first stage in a larger trial that GCG initiated to find ways to restore the native grasslands of this catchment. The message coming from these plots, about the value of autumn burning, is now about to be trialled further in a series of different grassland locations along the creek. I hope we shall hear more about that initiative.
Thank you, Ken, for a most interesting visit.
Lucky we were able to have this end-of-year ‘picnic’ under cover (with a portable barbecue for those who needed it) at the Jerrabomberra Wetlands office! There was heavy (but welcome) rain for the first hour or more, upsetting the schedule of walks to the bird hides. However, several people went out and explored later, after the rain, before dark.
This was a very cheerful informal gathering of ~30 FOG members and guests. The newsletter was packed and stamped for postage by a chatty group of record-large size, who then joined in the general munching and conversation.
It was an opportunity to informally ‘launch’ the first print run of Woodland Flora. FOG provided champagne and finger food; Sarah said a few words (see photos); and of the (literally) hot-off-the-press copies she had brought with her, none was left for her to take home! Imminent online publication of the FOG Forum (2014) Proceedings was also flagged. The evening was so pleasant we plan to run a similar event this year.

Mexican Feathergrass was found at Fraser Primary School and approximately 200 m away on suburban nature strips and adjacent parkland by a former ACT Government weeds officer.
Control measures are highly labour intensive and require good hygiene, including removal of plants, mulch and the soil seed bank, with double bagging of removed materials and deep burial at the Mugga Lane Resource Management Centre.
Follow-up control will be required for at least 5–6 years based on likely longevity of the soil seed bank.
Five Bridal Creeper plants were detected on the edge of the Barton Highway adjacent to the Gold Creek village.
Plants were hand pulled and sprayed and follow-up will need to occur for 5–6 years.
Established populations are currently being treated at Isabella Pond, Lake Ginninderra and Lake Burley Griffin.
Alligator Weed in Yerrabi Pond has been treated for 8 years to reduce the weed to single stems.
An incursion was detected inside the ACT border on the Kings Highway and the plants were pulled by hand.
A ranger detected incursions at Mt Gingera and Mt Ginini and pulled the plants by hand.
NSW has advised that eradication is achievable for this species because unlike most daisies the seed is not spread by wind.
Also occurs at Lake George and two areas in Wamboin.
This species of daisy is native to the Southern Highlands and other areas of NSW but not the ACT.
Plants have been found along Mugga Lane towards the entrance to the Resource Management Centre and seed was most likely spread off the back of a trailer. Plants in flower are being pulled up.
One plant detected in the long grass adjacent to Majura Road was removed.
Control activities in Crace and Forde continue to be successful in containing and suppressing imported-turf-related incursions, due to an excellent contractor and Jenny Conolly’s efforts identifying and removing seedlings before they flower. Note that seedlings can come into flower within a few weeks after emergence. Control activities will need to continue at these sites for at least 5 years.
Madagascan Fireweed has also been detected in imported turf in Coombs and Charnwood and may also come into the ACT with nursery plants and stockfeed. Imports from the Bega Valley are a potential source of contamination. Pathways for incursion need to be blocked.
No more Madagascan Fireweed plants have been detected along Mugga Way.
Five ACT Parks and Conservation Service staff went to Kosciuszko National Park to participate in a foot search for Mouse-ear Hawkweed in known infested areas in collaboration with NSW NPWS. The goal of the program is to eradicate the Mouse-ear Hawkweed incursion from the main range.
Mouse-ear Hawkweed has been detected previously in the ACT at Nursery Swamp but no plants were found during monitoring this year. Incursion is most likely in the ACT along high-use walking tracks.

It was with much sadness that we learned on Saturday 20 February that Benj had passed away at the very young age of 41. Benj was a passionate advocate for conservation, and, amongst other significant contributions, as an active member of FOG he for some years helped facilitate changes to the status of grasslands in the ACT and inspired others to care deeply for this poorly protected environment. Over the past years he became less involved as his illness restricted him more.
To quote from the Canberra Times notice:
‘Benj was well known around Canberra with his love of native plants, trees, birds, grasslands and The Pinnacle. He died peacefully at his place when his heart finally gave up. Gone too soon at 41.
A celebration of Benj’s life will be held at Crosbie Morrison Amphitheatre, Australian National Botanic Gardens, 12.30 pm, Friday 26 February 2016. Please bring a picnic rug or something to sit on.’
In memory of Benj
I met Benj about 18 years ago. He was a passionate young man loving all things in nature and who had a great knowledge of the natural world. He was then a bird keeper which may have sparked his wider interest. Having kept birds myself, I felt that this gave me some insight into him.
Recognising his passion, knowledge, social interaction and organising ability I quickly enticed him to join the Friends of Grasslands Committee – it didn’t require much effort. He became an active FOG member attending many events, contributing to all aspects of FOG, organising events and challenging those around him to think about the deeper issues of conservation, sometimes taking us beyond our comfort zone.
Benj always lived with his dicky heart and he endured long periods when he was not well and had to undergo medical procedures. Even when he was well, he was aware that his heart could let him down or limit his activities. Benj did not allow this to stop him leading a full life.
When he became more fully involved in Field Nats, being President of that organisation for many years, he applied his skills and energy in that group and always sought to work with FOG by organising combined FOG and Field Nats events.
My mum always said that only the good die young. I don’t know where this saying comes from but it is true in Benj Whitworth’s case. Thank you Benj for all the good that you have done. We will miss you.
Benj put his professionalism as an ecologist into action through membership of FNAC, Friends of Grasslands and COG but these involvements were based on love of and respect for ‘the bush’ that began in childhood. The natural history that Benj learned from the outdoors, and The Pinnacle in particular, was regularly shared and often informed his comments and submissions about land management in local reserves.
‘Twin Rivers’ is on Tuross Road, Nimmitabel, NSW. The property’s 225 acres is mostly bush, with approx. 5 acres cleared around the dwelling (see photo below). The environment is native bush with abundant wildlife, including platypus.

The photo at right is of Panicum effusum Hairy Panic, which is seeding prolifically in many places at this time of year.
The image is a collection of 4 spikelets, each carrying two florets, a pattern characteristic of this grass. Note that these spikelets were cut from their inflorescences and arranged for this photo. The stem of each inflorescence is about 40 cm long, carries a few hundred florets, and detaches as a rigid structure when mature and dry so that seeds are readily blown about by wind.
You may have heard in the last few days that at Wangaratta in Victoria the Hairy Panic has boomed this summer, and some homes have been troubled by huge banks of its seed heads piling up against doors and fences. See: http://www.bordermail.com.au/story/3739376/hairy-panic-strikes-photos/?cs=2452.
The photo was taken at the Seedbank of the Australian National Botanic Gardens. The white scale bar (at the bottom right of the image) represents 1 mm.
On the way back from the Pilliga in early spring last year, I came across the Dunedoo Woodland Learning Centre, next to the cemetery just outside Dunedoo east of Dubbo. This is an area of Box–Gum woodland remnant that was formerly a Travelling Stock Reserve. The site was protected and developed as a learning centre through a cooperative project involving the local community, the shire council, Landcare, NSW National Parks and Wildlife Service, Greening Australia and several others, with Natural Heritage Trust assistance. The theme expressed is ‘People and Nature: Educating, Conserving and Balancing’.
There is a 2 km track through the reserve, with a wealth of informative signs along the track. The signs include information about the tree species in the reserve, vegetation classification, common and rare woodland birds, woodland mammals and reptiles, and Aboriginal plant use.
Trees in the reserve include Yellow Box Eucalyptus mellidora, White Box E. albens, Grey Box E. macrocarpa, Blakely’s Red Gum E. blakelyi and Rough Apple Bark Angophora floribunda. When I was there on a short visit in early September, the White Box was flowering, as was Senna artemisioides and Cryptandra amara. Forbs in flower included Vittidinia spp., Stackhousia monogyna, Craspedia variabilis, Chrysocephalum apiculatum, Bulbine bulbosa, Ajuga australis and Asperula conferta.
I managed an even shorter visit on the way back from Brisbane a few weeks later, when more was in flower. There were more daisies (including Xerochrysum viscosum), a couple of species of Goodenia, and Wahlenbergia, Lomandra filiformis, Diuris sulphurea and a few other forbs I was unable to identify. I’m sure a longer stop would have revealed more.
If you are going up past Dubbo, a stop at this little reserve is well worthwhile.
Bush Stone-curlew Burhinus grallarius, a nocturnal ground dwelling bird
Bush Stone-curlews were once distributed throughout Australia but their range has been reduced significantly since European settlement. They are ground dwelling birds that like a spacious habitat, such as Box–Gum grassy woodlands, grassy plains and open forest. They are large, with a wingspan of 55–60 cm, and are also nocturnal, feeding mainly on small animals of all kinds, such as insects, spiders, molluscs, frogs and lizards, and less often seeds and tubers. During the day they are usually inactive, sheltering among vegetation. More often heard than seen, their presence is recognised by their eerie drawn-out call of ‘wer-loo’, usually done at night. Their feathers are mottled and streaked with brown, black, grey and cream colours, with male and female being quite similar. This plumage makes them hard to see when standing motionless in tall grass or crouching on the ground in dappled shade, and this is a major ploy for protection from predators. They seem reluctant to fly, and when approached their habit is to walk away stealthily with head down, and if pressed they will fly away a short distance. They nest in a small cleared space on the bare ground. Although common in the north of Australia, they are listed as endangered in New South Wales. Locally they are extinct in the wild, having last been seen in Canberra in the 1970s. The main reasons for this are changes to their natural habitat and the introduction of foxes and cats.
When we look at the reasons for the decline of particular animals, the superficial causes may be similar to this case. But looking back in time we see there are more universal reasons. When Britain colonised Australia the industrial revolution was gaining momentum in Europe but world population was still relatively low, approaching one billion. With the improving farming methods the production of food became easier and populations expanded. At that time empire building was very popular and the Europeans sought to increase their wealth and influence by creating colonies and exploiting the abundance of other continents. There seemed to be an unlimited supply of natural resources in the far-flung places of the globe. The new colonies grew rapidly and the numbers of people increased everywhere. Along with this expansion and labour saving machines, industries became more and more productive. At the same time, the landscape was being transformed by the expansion of agriculture, forestry and towns, to feed and house the growing populations, leaving an ever-decreasing amount of land for the wild creatures. In the natural world, species’ populations fluctuate with the seasons and living conditions. But with advances in technology and medicine our numbers have increased continually and there are now over seven billion people on Earth.
During the twentieth century economics developed as a social science and became a prominent political tool. With it evolved the idea that a good economy is one that is constantly growing. Nowadays whenever our economy is not growing there is great concern. If there is a downturn and our economy shrinks it is called a recession and is regarded as a major problem. This attitude is common throughout the world. Poorer countries are constantly trying to catch up with the wealthier ones, which in turn compete with each other to be near the top. Such a philosophy inevitably leads to the need for more and more resources – more land, water, energy, trees and mines. But the planet is finite in size and the world’s resources are not unlimited. This continuous growth has come at a great expense. As rapidly as our population and prosperity have grown, biodiversity has gone downwards and species are frequently becoming extinct.
It is wonderful thing to have children and raise a family. It is an essential part of life. And it is only natural for people to want to live in comfort and increasing prosperity. But our own comfort and prosperity, and the number of children we have, are inevitably at the expense of the wellbeing of the wild animals and plants. So it is an extremely difficult issue. There are very few of us who would choose the safety, comfort and abundance of other living creatures ahead of our own. How do you convince seven billion people to do so?
I did the drawing of the Bush Stone-curlews from photos I took at the National Zoo and Aquarium. There is also an experiment at Mulligans Flat Nature Reserve where some birds are successfully living in the protective enclosure there. This is very satisfying. So too are many of the things FOG has achieved. However, as long as the two trends of increasing population and continuous economic growth persist then FOG will have work to do and new challenges.
