The next scheduled Mt Rogers working bee is on Monday 7th March. We’ll meet at Wickens Place, Fraser by 09.00am and return to the task of tackling weed species that will be dispersing their ripening seeds within the next few weeks.
With the determined efforts of dozens of volunteers over the past 25 years Mount Rogers is relatively free of woody weeds such as privet, cotoneaster, firethorn, honeysuckle and hawthorn. Woody weeds come into the 65 hectare reserve as berries that birds have feasted on while in suburban gardens or the ACT’s green spaces on public land. Several infestations of Blackberry are constantly monitored. They and Chilean Needlegrass, Serrated Tussock and African Lovegrass attract assistance from TCCS* rangers and employed contractors.
Landcare volunteers at Mount Rogers are dispirited by the extent of weed growth due to the rains and the fact that the seeds of many species have germinated and grown after years of dormancy in the soil’s seedbanks. We are planning to continue the Bradley method of weeding where we work from the centre of each biodiverse section of the reserve cutting or treating any species that are a threat to the biodiversity of the native plants and animals. https://www.aabr.org.au/learn/what-i-bush-regeneration/general-principles/the-bradley-method/ We also weed by concentrating on specific places, track sides and learning identifications by focusing on one weed species at a time.
Where the soil is damp most of these species pull out quite readily with steady but gentle effort with some species and especially Verbascum (also called Mullein) needing attention now. We cut the flowering heads off and bag them leaving the pulled, green stems and leaves to dry and then rot down and fertilise the soil. Later in the season we will dig out many rosettes of Verbascum leaves. The grey-green leaves are quite attractive and soft to touch.
The biodiversity in some sections of the reserve is an extraordinary contrast to the rest of the reserve even though the native wildflowers are often hidden by annual weeds and introduced grasses thriving on the rain events of the last nine months.
Grass
species from other countries were brought to Australia in the days when few
landholders or even “agriculture departments” understood the land and
Australian soils and plants in the way Indigenous peoples did. They expected to
succeed by transferring European farming methods to the very different landscapes
of the ancient continent. The species were often introduced to fix specific
problems such as erosion but without the insects and grazing animals that
controlled plant numbers in their original regions, the new arrivals thrived to
became invasive species that threatened the survival of native grasses and
wildflowers.
The mowing operators have recently reached Mount Rogers again. They have an enormous job trying to keep up with the growth of African Lovegrass resulting from the regular rain events coming through the ACT. I expect it’s possible to find out from the ACT Government’s website how many hectares need mowing in the ACT but it’s many, many thousands. As you’ll have noticed, several different types of mowing machines are required. I doubt if any are manufactured in Australia.
All through Sprummer individual Landcare volunteers have continued their observations, reporting and weeding efforts. St John’s Wort is a prime target because each plant can produce thousands of seeds and the plants also spread with sucker-like roots through the soil.
Ideally SJW, this very invasive
species, needs to go to the tip to be deeply buried.
We have chosen to work on SJW now
because, with the ground being still damp, the plants pull out with a
determined, steady pull. Normally pulling causes the suckering roots to break
off, a signal to the plant to respond by growing new plants from the broken
root pieces.
The plants are more mature than
those in photos with numerous capsules containing seeds maturing but not yet
ready to be dispersed. There are several articles about SJW on ’the web’ one of
which stated that one plant could produce 33,000 seeds.
The seeds remain viable in the
soil for 12 years which is why Mt Rogers has seen a rash of SJW patches through
the reserve this sprummer in spite of the Landcare Group’s consistent action
against the invasive species over a decade or two.
Why work on only one weed? There
are so many invasive species that have gone berserk with all the rain. We are
concentrating on weeding near and outwards from Mt Rogers' best vegetation
areas or on specific species that spread thousands of seeds. (Currently Thistles,
Euphorbia, Fleabane, Verbascum, Mustard.) Ann has posted some photos in the new 'page' (right hand column of the screen) called
'2022 summer weeds gallery', on the blog site, mtrogerslandcare.blogspot.com
Here is mustard, close up,
and below is a view of the effects of mustard's yellow blooms on the Ginninderra Creek landscape beyond West Macgregor in 2020.
During a working bee on Monday 7th
February Phil and I pulled up hundreds of St John’s Wort plants whilst Steve D
returned to Bridget’s to repeat spot-spray an infestation of African Lovegrass
there as we worked north of Jacob Place. The Sunday 23rd session saw
three of us working on isolated plants north of the main carpark in Fraser. Ted
walks daily with a wand to daub specific invasives as he comes across them.
Each of our regular landcarers carries a pair of gloves whilst focussing on
weed species they know as they walk on ’the hill’.
1st
Monday and the 4th Sunday. The meeting places vary according to the
tasks that are prioritised each time.
As
mentioned above our community members contribute numerous landcaring acts each
time they are in the reserve. Observing nature, recording wildlife and plant
species, welcoming newcomers, collecting rubbish when found, monitoring erosion
run-offs, sharing enthusiasm for the reserve and its habitats.
Our group is one of over 25 energised communities determined to make a difference for wildlife, waterways and habitats in the Ngunawal land catchment area of Ginninderra Creek. The creek rises in Mulligans Flat making its way through its floodplain until water reaches the spectacular 40m waterfall in NSW at Parkwood, and the Murrumbidgee River beyond Macgregor. If you’d like a map of Ginninderra Catchment a new one was published in 2021.
The catchment’s Landcare and Parkcare groups come under the ‘umbrella’ of Ginninderra Catchment Group (GCG) based at Kippax. GCG provides ecological and land management advice and networking. We also have considerable operational and liaison support with other government agencies from *TCCS (Transport Canberra & City Services) volunteer co-ordinating staff.
There are
other ways to contribute to nature’s health with volunteering opportunities
through Frogwatch, Turtlewatch and Waterwatch. Their co-ordinators are also
based at Kippax.

Greetings to Mt Rogers’ carers’ community as, in theory, a new year of twice-monthly Landcare activities begins.
Seven people made a difference in the reserve on Sunday 28th November. There were two apologies. Thank you Colette, Grace, Kerri-Ann, Phil, Roger and Ted.
In spite of occasional light showers as I walked through the reserve there was quite a flurry of bird activity including at least 5 Superb Parrots feeding from the flowering eucalypts.
Here’s a reward for our volunteers' painstaking work against the rocks-dumper’s activities a month ago. There were four of these Fringed Lilies in bloom at ‘Bridget’s’ yesterday.All four plants were in the area landcarers cleared of garden debris.
Steve’s work against the African Lovegrass ‘near’ the red gate is remarkable.
Monday 6th December will be the final scheduled working-bee for 2021 and we’ll likely meet at Rechner Place, Flynn for another walk and weed session against weeds threatening the best quality areas in the south-west of the reserve.For our next two Mt Rogers sessions:On Sunday 28th November the WORKING BEE volunteers will meet at Mildenhall Place, Fraser at 09.00am.Ted has highlighted a patch of Euphorbia to behead and bag and then pull out.There are also Verbascum and Fleabane to attend too.And detailed weeding near the Cryptandra patch all tasks we could walk and weed to if enough people are able to be there.
THANK YOU!,Rosemary
Dear Landcarers
In theory there are three more scheduled working bees before the end of 2021:
Working bees
The Landcare Group’s
next working bees are scheduled for Sunday 25th July and
Monday 2nd August. We will be looking amongst the
grasses for the soft-leaved Verbascum rosettes, having found they often
dig out fairly easily and without too much soil disturbance now the ground is
wet. We’ll meet at Schwarz Place’s eastern arm at 09.30 on 25th.
Bird sightings
Chris and I have
seen Scarlet Robins on separate occasions. I’m not sure if the Robins' numbers
are down for this winter spent on and around Mt Rogers. They move to the high
country in early spring in order to nest there, but how many of these species
that make those seasonal migrations were caught up in the devastating fires may
still be unknown. A couple of weeks ago I saw a group of Choughs scrabbling
away beside the trunk of an old tree east of the Notice Box. They are fun to
watch and a bit like a flock of chooks with a definite sense of humour. Any
time now there will be insectivorous bird activity in the flowering Cootamundra
Wattles as the seek out any invertebrates that are amongst the yellow blossoms
when the sun has warmed them up.
Drainage
Rain events during
this wet winter show how the water flows from Mt Rogers’ ridge-line both over
the currently saturated ground and by seeping out from under vegetation. Phil’s
run-offs are effectively channelling water away from cross-country paths and
tracks and into the landscape. The water reaches Ginninderra Creek and
eventually the Murrumbidgee River.
There are many streets in Flynn, Fraser, Spence and Melba where water is also draining down under or between houses. Perhaps some of these seepages are following ancient routes that would once have watered Grassy Woodland, ancient eucalypts, Native and Rocky grasslands and the shrubs and wildflowers of diverse pre-grazing habitats. Once in the streets’ drains the stormwater makes its way, piped, towards Ginninderra Creek. Waterwatch volunteers regularly test its quality, oxygen levels and temperature.
Pollution
You’ll have driven
past the ‘new’ rain-garden and wetlands at Florey, Evatt and Melba. Their
plants act as filters taking chemicals and fine particles out of the stormwater
from the suburbs’ drains before the water can enter the creek. In reality, all
the stormwater drains that serve the suburbs need wetlands for filtration and
to slow the water down. Fast flowing water causes the erosion of creek banks
and, surely, downstream residents shouldn’t have to drink some of the fluids
that leave our properties. See ‘H2OK: Keeping our Waterways healthy’ (at https://www.environment.act.gov.au/water/act-healthy-waterways/h2ok-keeping-our-waterways-healthy).
Evatt wetlands (left and below).
I was watching a video about the River Wye that runs along the border
between England and Wales, the other day. The river’s aquatic life is being
killed by pollution from poultry and pig farms. Chemicals from the animals’
dung are washed into the Wye. There are regulations against this but
insufficient resources to ensure compliance. Fertilisers from our gardens can
have similarly toxic effects here, causing algal blooms in waterways.
From our gardens
Until this last
year the Landcare volunteers were able to cautiously rejoice that the majority
of ‘woody weed’ species could be seen growing in people’s gardens rather than
in the Mt Rogers reserve. Once the drought broke and the seed bank in the
rehydrated soil was stimulated, germination of these dormant seeds reached epic
proportions. The numbers of annual and biennial weed plants reached trillions.
Simultaneously native orchids, lilies, daisies astounded naturalists by
appearing in large numbers or in places where they’d never been sighted before.
Berries
The trees and
shrubs in gardens responded to the rain by producing millions of flowers that
fed thousands of pollinators. Neighbours’ gardens and suburban laneways have
berries of all colours; red, orange, black-purple, yellowy green, black and
steel blue. Silvereyes, rosellas, currawongs, starlings, Indian Mynas, King
Parrots, Bowerbirds – species both native and introduced – have feasted on
these berries. Some bird species enhance seeds’ chances as the fruits make
their way through digestive systems; others crush the seed beyond viability.
There will be plenty of woody weed seedlings germinating from birds’ poo that is
dropped into the reserve.

Resources for
Landcare & Ginninderra Catchment Group
On 24th June,
Landcare volunteers received this message from Kat McGilp, who is the co-ordinator
of Ginninderra Catchment Group.
“It has
recently been announced that the ACT Government's commitment to funding
the three Catchment Groups for four years was confirmed by Minister Vassarotti
in the Legislative Assembly early today.
The annual funding
amounts are yet to be finalised, but it has been indicated that each catchment
group will receive base funding, as well as Waterwatch and Frogwatch
funding.”
The vital news is that this funding seems to be assured for 4 years, meaning that the Catchment Groups’ ecology and land management-trained staff won’t have to spend hours seeking funding as the end of each financial year approaches. The commitment also indicates that there is some acknowledgement, in senior government ranks, that the landcaring we do on land that is not part of Canberra Nature Park’s reserve system is as important as the ‘parkcaring’ done by our volunteering ParkCare colleagues. ParkCare groups work just like we do in landcare, but they are on land in the Canberra Nature Parks – which have held higher conservation status for decades.
There are three catchment groups in the ACT. Each is an umbrella organisation advising and supporting the hundreds of volunteers who care for open spaces and waterways’ corridors that were initially mainly important for hosting utilities such as powerlines, roads, paths, sewer lines.
As people made time to explore beyond their homes and beyond the Canberra Nature Park (CNP) Hills and Ridges that frame Australia’s bush capital, they discovered remnant woodlands, residual Natural Temperate Grasslands, groups of boulders that protect native species, and views and creek-lines that revealed how Indigenous peoples had thrived on and travelled through Country for millennia prior to colonisation.
People from all walks of life became informal landcarers and citizen scientists, emerging with native species lists, weed lists, tools to tackle the most invasive species and, occasionally, with family projects to plant, build cubbies, make extra tracks and commemorate loved ones. They’d discovered local places where recording and conserving cultural, natural and inspirational treasures was as important as collecting data from the CNP gazetted reserves managed by the ACT Parks and Conservation Service.
The ACT’s open spaces, smaller reserves and some riverine corridors are managed by land managers from TCCS (Transport Canberra & City Services). Ginninderra Catchment Group (GCG) supports volunteers working on the TCCS-managed lands where rainwater drains into Ginninderra Creek. There are TCCS rangers or Coordinators who provide liaison and links between GCG’s landcaring volunteers and the ACT Government’s processes and personnel.
For mobile fauna species and the plants whose pollen, spores and seeds they disperse it’s vital that areas of bush and complex habitats are of appropriate size and shape and that they’re not disconnected from other similar areas. For native animals and plants, consistent and respectful landcaring suited to their habitats’ needs will help them thrive and reach their potential. Healthy habitats and ecosystems bring enormous benefits to the reserves’ thousands of visitors and appreciators.
‘Engaged communities for healthy habitats’ is GCG’s motto. There’s a brochure with a map of the catchment available through me (ph 6258 4724) or via GCG (ph 6278 3309 in office hours) if you’d like to see the extent of our habitat and find out where the Landcare Groups are located.
