September work & progress. And on Oct 18, come and learn about Kuringa Drive !

On Thursday 17th an exceptional turnout of Mt Rogers Landcare community members put 18 coir logs in position down the eroded track from the summit. There are four photos of this below. 

The hardest part proved to be creating a hole through each log four times so the stakes could be driven into the ground.
We loosened the compacted soil, scattered native grass seeds and covered the seeds. Some Capeweed plants were dug up to prevent them seeding but, as the second photo might show, the flowers continued to bloom. They still turn to the sun four days later….!
The alternative track across the grass to the north is being used….there are several others in the vicinity including the main vehicle tracks.
Thank you Margaret for surprising us with warm-from-the-oven morning tea that we eagerly ‘washed down’ with our supplies of water. 
Julie, Kerri-Ann, Mark, Michael, Neil, Phil G, Phil N, Ted have new skills for their CV’s and there were apologies from Angharad, Colette, Helen and Jennifer and Steve.

On Sunday 27th our next working bee is scheduled. 
I suggest we meet near the Flynn playground again and at 09.30am
There are several areas of native vegetation that have flatweed, thistles, prickly lettuce, capeweed, fumitory interfering with their wildflowers’ potential. 
Most of these pull out in the dampened soil at the moment…though hand weeders are currently the best tools for the job.
The growth of oats, introduced grasses is phenomenal and one must wonder how the ash from the prescribed Hazard Reduction Burn in 2018 (plus rain) has helped these grasses and weeds recreate the fuel load the HRB’s are supposed to reduce………
Angharad reported that the Frogmouths had abandoned the nest she found. 
I came across an Echidna near Snow Gum Corner today. Whilst showing it to Tracey I learned that there’s a pair again nesting in Schwarz Place trees.
I heard Friarbird calls today up near the Summit. They are returning to our region to breed.
Margaret had a wonderful observation of Superb Parrots feeding “a baby”….this very early breeding record has intrigued the COG*

There will be a gathering in the Kuringa Woodland (parallel to Kuringa Drive) on Sunday October 18th with the aim of introducing the woodland's habitats to their Fraser and Spence neighbours, from 10am. ALL WELCOME.
This is being organised by ecologist, Michael Mulvaney, of EPSDD (the “environment department) and Sarah Sharp, retired grassland ecologist. Perhaps a Landcare Group will eventuate for that area. 

On Saturday 19th there was a walk around the new wetlands at Melba. A similar walk is planned on 26th at the Evatt wetlands below the dam wall. Entry from Croke place and starting at 3pm.  
The native grassland experimental plots there will be explained. 
Both events are organised by Ginninderra Catchment Group (GCG) to show how water entering GInninderra Creek is filtered by such installations and how sediment is trapped by aquatic plants in the wetlands’ settlement ponds. 
The catchment group is the umbrella group for Landcare Groups in our area, supporting what volunteers do and what they hope to achieve for the special places we love. 

For the erosion work we had a great deal of partnership help from TCCS ‘rangers’, the operations team at Charnwood Depot and from the GCG staff…..your rates working for Mt Rogers (as well as all the other reserves around the bush capital).

Cheers,
Rosemary

Mt Rogers news September 2020

The eroding track down from the Trig Point towards the east

Previous newsletters reported on February’s efforts when twelve Mt Rogers Landcare Group volunteers had process discussions and began work on allowing the eroded track to and from the Trig Point to repair itself.

The track is straight up and down, and so feet, wheels and the effects of drought, wind and water-flow have worn away the thin soil and exposed rocks and tree roots. To avoid this track becoming a narrow but deepening and dangerous gully the group decided to initiate repair processes via a partnership with the Land Managers at Transport Canberra & City Services (TCCS), the Ginninderra Catchment Group and TCCS’ operational staff based at Dunlop Depot.

Here is an update from the project’s volunteer managers:

Mt Rogers Landcare Group is committed to meeting strong community requests to attempt to rehabilitate the summit track.  Accordingly a plan has been developed and the following measures will soon be implemented via a working bee (timing TBA) as well as some individual and TCCS effort.  This includes:

1. Temporary, physical barriers at the top and bottom of the track,

2. Signage explaining the action and the need for repair,

3. Coir logs across the slope to limit runoff, to limit erosion of soil and silt and to encourage regrowth of grass and other ground cover species.

4. Some planting of natural grasses,

5. Preparation of an alternate route to the summit which traverses across the slope a little further to the north rather than straight up, to limit the potential for erosion. 

 We’re close to having during-the-week dates for installing the coir logs, planting out grasses and covering the track and its sides. Branches will be used encourage seeds in the soil to germinate undisturbed and to prevent kangaroos eating any new plants.

Please let me know if you can spare a couple of hours to be part of the rostered working team for this project. No previous Landcare experience or attendance at our working bees is needed….enthusiasm for contributing muscle-power to Mt Rogers is probably the most needed attribute!!

 

And here’s the signage that will accompany the Summit Track EROSION works:

    

ATTENTION MT ROGERS COMMUNITY

 

·    THIS AREA IS TEMPORARILY CLOSED

·    TRACK REHABILITATION AND EROSION MITIGATION IS IN PROGRESS

·    PLEASE USE ALTERNATE ROUTES TO ALLOW NATURAL REGROWTH

·    YOUR COOPERATION AND ASSISTANCE IS APPRECIATED

THANK YOU

Mt Rogers Landcare

Explanatory note:

A combination of drought and increased use by people during COVID-19 has resulted in increased erosion of this already badly degraded track. In response to strong community concerns to protect this site, erosion mitigation measures and seeding of native grass will be undertaken.  For these measures to succeed, we have temporarily closed the area for community use. Please use the main vehicle tracks or alternate routes and avoid steep direct pathways straight up and down the hill – kindly “zig zag” or “contour” the slope to prevent erosion gullies developing.  This project is a joint initiative of your local Landcare Group and the ACT Government.

HOW MANY OF THESE EVERYDAY GARDEN WEEDS ARE NEAR YOUR PLACE THIS YEAR?

Each year weather conditions, together with rainfall amounts and sequences, lead to variety in the herbaceous weeds commonly found in gardens and on nature strips around the region. Once native plant diversity was altered after European settlement, seed banks of introduced plant species built up in the soil. The seeds wait for ideal germination conditions. I’ve not included grasses (except Wild Oats), though African Lovegrass is rampant on suburban nature strips.  

Species in bold are over-successful this year!

The species listed are those I’ve noticed in north Belconnen. Other areas may report additional or different species. In 2020 these weed species area also present in the territory’s reserves. Plant species are known as weeds when they have no predators, grazers or harvesters to control their numbers. Some species are edible for humans, at least when the plants are young. See The Weed Forager’s Handbook for details.

These weeds are accepted for high-temperature composting at the Green Waste sites…such as Corkhills’ and Canberra Sand & Gravel’s yards.

At home: if the weeds have set-seed put the seed-heads in a black plastic bag to ‘cook’ in the sun rather than putting them in a home compost bin or heap that may not be hot enough to kill the seeds.

Many households now have green bins to which weeds can be added for commercial composting.
