We hope you have had a wonderful holiday season! Now, it is January and that time when many of us reassess our busy lives and think about what we want to accomplish or do to balance our lives during the next year. With that in mind, here’s to peaceful days on your Bushcare sites with friends.
Here’s hoping that time off over the holiday season has not had too much impact on your Bushcare site. It is inevitable that with the recent storms and heat across the Blue Mountains that your patch may have undergone significant changes while you were gone.
Bushcarers are doing people and would just love to get in there and get the site cleaned up straight away. Stay safe in the hot weather by taking a few precautions:
Schedule your workday by weeding in shaded areas
Take regular breaks
Drink lots of water
Wear light and loose-fitting clothing
Pace yourself and rest when you need to
Keep an eye on each other for signs of heat exhaustion
We have a fun filled program planned for Blue Mountains Bushcare this year. It is different to previous years with new training courses and workshops in that you will be taking part in to enhance your knowledge of your site and the surrounding catchment, so keep an eye out for these on the Bushcare Website, Gecko and Bulletin.
Looking forward to catching up with you all over the year ahead.
This research may be of interest to Bushcare Groups that have worked their patch for over 10 years.
See details below on how to participate: The Department of the Environment and Energy, together with the CSIRO are undertaking an investigation to understand how Australia’s biodiversity has been changing in recent years. As a part of this investigation we are seeking to understand how the 1°C increase in surface temperature experienced over the past century may have contributed to recent changes in biodiversity across the Australian landscape.
To this end we are very interested in hearing about the experiences and observations of people who are familiar with different parts of Australia. We hope that their insights and stories will provide us with a unique view of how things are changing. To participate, you would need to be able to select a natural area (e.g. your local region or farm, a Nature Reserve, urban bushland) that you have been familiar with for at least the last 10 years. Note that we are interested both in areas where change has been observed and where change has not been observed. The survey can be found here<https://csirolandandwater.au1.qualtrics.com/jfe/form/SV_dcjRc0gqVUMKeiN> and is made up of a series of observational questions and an open section for people to tell us their stories. It would take about 30 minutes. Additional information about the project can be found here<https://research.csiro.au/biodiversity-knowledge/projects/recent-history-climate-driven-ecological-change-australia/>”.
Last year marked 20 years for this stalwart group of volunteers and they have successfully confronted just about every issue a Bushcare group can face – not just weeds but serious erosion and the ongoing impacts of urban development. To celebrate this achievement the film Blue Mountains Bushcare: South Lawson Park has been produced by Peter Ardill and Vera Hong. Directed by Vera Hong (Seconds Minutes Hours Productions) the film examines bushland values, the ongoing threats that urban bushland faces and how the bushcare group has managed these challenges. The film contains some beautifully filmed scenes of the Lawson Creek catchment and is available for viewing at https://vimeo.com/verahong/south-lawson-bushcare Thanks to Greater Sydney Local Land Services, the Australian Government’s National Landcare Program and Blue Mountains City Council for project support and funding.
The South Lawson Group first started in mid-1995 with the then only Blue Mountains City Council Bushcare officer, Virginia Bear. Our aim was to regenerate and maintain the health of the upper catchment of Lawson Creek, which flows into Bedford Creek and the Nepean River.
The early years were spent mostly at the top of the Waratah St/Honour Ave section of the reserve (see map below) where Japanese honeysuckle, Privet, Montbretia, Blackberry and Broom were major invasive weeds. Some seed collecting, planting and track work were done, the latter with help from TAFE students under the guidance of a Bushcare Officer/TAFE teacher.
We expanded our weeding to the creekline and over the years to the surrounds of the BMX track and soccer field. In more recent times we have been extending the riparian buffer zone along the creek and swamp of the former golf course area by planting and allowing the bush to regenerate naturally. Some of us are also actively involved in Streamwatch and this process has been both informative and complementary for our Bushcare work.
Extending the buffer to the riparian corridor by planting with local natives.
The main vegetation communities along the creek are Eucalyptus woodland, Blue Mountains Swamp and a riparian strip of assorted native plant species, including rainforest species. The threatened species Persoonia acerosa and the endemic species Acacia ptychoclada are also present.
Our group is very committed and we are fortunate to have a few bush regeneration practitioners amongst us. Our website is also worth a look at: http://southlawsonpark.bushcarebluemountains.org.au It has some interesting photos and excellent educational material.
Greater Sydney Regional Weed Committee is very keen to hear from as many people as possible on the plan so we hope you can make one of the information sessions.
INVITATION TO A PUBLIC CONSULTATION FORUM on the Draft Greater Sydney Regional Strategic Weed Management Plan
The draft Greater Sydney Regional Strategic Weeds Management Plan (GSRSWMP) will be released for public consultation on 8 February 2017. The plan has been developed as part of the NSW Government’s Biosecurity reform process in response to the Natural Resources Commission’s review which identified the need for a more coordinated approach to managing weeds.
It is estimated weeds cost the NSW agricultural industry about $4.3 billion every year. Weeds also have serious implications on our lifestyles and the natural environment. Native biodiversity in particular has suffered declines in the distribution of many species as a result of invasive plants.
The GSRSWMP will provide the framework for improved management of weeds on both public and private lands by guiding investment to achieve the greatest outcomes in prevention, eradication and containment.
The draft plan was developed by the Greater Sydney Regional Weed Committee in partnership with Local Control Authorities (i.e. local governments), NSW Department of Primary Industries, National Parks and Wildlife Service, environmental interests (i.e. Nature Conservation Council), Landcare, NSW Farmers Association, Nursery and Garden Industry Association and Aboriginal and public land managers.
The Plan will now be made available for public consultation for feedback before being finalised. As part of the consultation process, Greater Sydney Local Land Services and the four subregional weed committees will host five public forums across the region. The purpose of the forums is to explain the contents and impacts of the draft plan, respond to questions and assist anyone who is considering commenting on the draft plan.
A Forum will be held in Penrith at the Cambridge Park Community Hall 97 Oxford St Cambridge Park on Tuesday 7 February from 5pm -7pm.
This year BMCC sponsored 2 one-day workshops for Bushcare. Bushcare Boosters is a three-part course which was designed by the Sydney Metro CMA, Volunteers Co-ordinators Network in conjunction with the Australian Association of Bush Regenerators and several local councils.
We’re aiming to ensure that our community conservation program volunteers are up to date with the current best practices in Bushcare and the opportunity to develop the highest standards possible—the ones we are used to!
To that end, we decided to hire an expert trainer, Geoff Bakewell, who is very experienced in Bushcare and is certified to teach the Bushcare Boosters program, a combination of classroom and field based learning. Geoff has worked as a Bushcare Officer and has delivered Bushcare Boosters to Bushcare volunteers for both local and state government.
So far, we have covered two of the three modules. Module 1, “Bushcare and the Big Picture” looked at the history of Bushcare, the values, problems, plants and animals present on Bushcare sites and the development of site strategies. It was held at South Lawson Park, a good example of a site with many values and complex issues to keep its Bushcare volunteers busy.
Module 2, “The Birds and the Bees of Bushcare” was at another long-term Bushcare site: Jackson Park, Faulconbridge. We spent half a day discussing habitat— how to assess it, find evidence of fauna occupying it, how to look after it.
The third module will cover weed control technique and safe work practices. It is yet to be scheduled, but we will run it as soon as we can—so stay tuned for more information or contact Monica at the Bushcare Office on 4780 5528 or email@example.com
by Dan Marshall, Coordinator Three Gullies Landcare Group
Three Gullies Landcare (3GLC), as its name implies, consists of three gullies in an area of land bordered by the railway line and Bruce Rd Glenbrook, south of Eureka Rd to number 39 Bruce Rd. The three gullies are fed by watercourses from the east and ultimately deliver the water to Glenbrook Creek via culverts under the railway corridor.
The three gullies are the intermediary from the much higher eastern side residential dwellings, road and water drainage systems and in heavy rain carry significant water flows. Over time, this water flow has caused significant erosion, particularly in Gully One.
During my time with 3GLC, we have used traditional log retaining walls to help slow down the flow. The logs were sourced on site from fallen trees and from removal of weeds. These log walls are situated at various locations along the creek and are of varying heights and widths (depending on the logs available at the time). Although these log walls worked well, retaining silt during low water flows, they were no match for the rate of flow during periods of high rain fall and more importantly didn’t stop erosion of the creek beds.
I discussed this with Tracy Williams and Eric Mahony from Blue Mountains City Council’s Bushcare program for their input. As a result, the plan for an onsite practical workshop was proposed. Timing is everything in life and presently funding is available for assistance and the main material (flat sandstone rock) is cheaply available from expanded pits at the local Blaxland tip.
So on Thursday 9th June, 2016, after initial discussions and a briefing session, and with a workforce headed by Eric Mahony and contractors from “The Bush Doctor” under Shane Grundy, Tracy Williams, the 3GLC and neighbouring Landcare groups (Bush Place, Raymond Rd and Cox Reserve), the work began. Well, mainly the “Bush Doctor” group (about 9 fit young men!) did the heavy lifting of moving the sandstone from the roadside down the gully to appropriate locations along the creek.
Of course, the starting point was at the lowest spot in the gully at the Railway built culvert and then using a step of 300mm (ruler length) the first step was installed using a bed of Bidim (Geotextile fabric). The Bidim was laid and dug in along the leading (upstream) edge, and covered by flat rock at the spill over point and underneath the water fall. The sides were lined by sandstone pieces wedged into the side of the creek wall to reinforce the wall and to direct the water over the flat rock.
Other materials were used such as skinny coir logs held in place by wooden stakes to fill undercut sections of the creek. Existing native plants in the creek bed were protected by hessian mat with appropriate cut outs for the coming plantings. Ultimately further 300mm (ruler) steps continued up the creek until a flat stretch of the creek was reached where future planting of natives will further aid in slowing the flow. Ultimately approximately half the creek was upgraded and plans were made for another day later this year. It is hoped this allows more plants to be laid and the new work to be settled in.
Log retaining walls are fine provided the wall is lower in the centre, otherwise the water will flow around the outside creating more paths;
Drops should only be 300mm or less to prevent “boiling” causing undercutting;
The base of drops must be solid impermeable material;
Natural bends in the creek can be reinforced on the sides but its best to keep drop offs some distance away to minimise the rate of water flow entering the bends;
Deep pools can be used or encouraged as spots for aquatic creatures (platypus would be great but unlikely)
Silt gathered before walls needs to be monitored and removed where necessary.
Finally it was a pleasure to have a break from weeding for 3GLC and to meet the members of the nearby Landcare groups as well as to have the input from Eric Mahony and the Bush Doctor workforce. Of course the excellent morning tea supplied by Tracy Williams fully replenished us all so we could carry on working until knock off time.
The members of 3GLC look forward to the next instalment.
The next meeting is scheduled for Wednesday February 1 at the Mountains Community Resource Network meeting room, Lawson Library building, Lawson. All welcome, especially the co-ordinators of each Bushcare group. The main item on the agenda is the purpose and future direction of the Network. Please come and contribute to the development of your Bushcare Program!
On May 2 the Leura Falls Creek and Jamison Creek Catchment Working groups came together along with Blue Mountains City Council Natural Areas and Healthy Waterways teams to do “catchment crawls” (minibus tours of the key work sites) in each other’s catchments. Residents of the Vale St end of the Leura Falls Creek catchment were also invited.
In the morning, the Leura Falls Creek tour showcased the recently constructed stormwater upgrades including the Vale St Baramy Trap and raingarden – shown below in full flow with the recent heavy rains in early June. The Jamison Creek Working Group had an opportunity to see what types of stormwater management systems will be installed in the Jamison Creek Catchment in the near future.
After lunch, a tour of Jamison Creek Catchment gave us a chance to learn about where the upgrades are planned and how they will be constructed.
The stormwater improvement projects in both catchments are an initiative between Water NSW and Blue Mountains City Council. The catchment crawl was filmed by KFM Media, Katoomba. Thanks to the tour guides, Eric Mahony and Geoffrey Smith from Blue Mountains City Council and Peter Bennet who designs the Baramy Traps. Thanks to Monica Nugent for driving the bus. And thank you to every one who came on the tour.
At a special awards dinner on Wednesday 6 April, the Leura Falls Creek Improvement project was announced as joint winner of the 2016 NSW Award for Excellence in Integrated Stormwater Design. Congratulations to all the Blue Mountains City Council staff and contractors involved in the project and the Leura Falls Creek Catchment Working Group.
