Minnehaha Falls plunge pool – full of sediment washed into Yosemite Creek from many years of urban development
This year at the annual NSW Local Government Awards, the Blue Mountains City Council and the local North Katoomba community was recognised for its outstanding work over many years, winning the Division C and Overall Category Winner of the Natural Environment Protection and Enhancement: On-Ground Works Award, for the project the Return of the “Bottomless Pool’ in Yosemite Creek, North Katoomba.
The result is the culmination of decades of work addressing urban stormwater runoff and weed invasion, which had previously resulted in sedimentation, erosion and decline of Yosemite Creek’s water quality, as well as loss of habitat and aquatic biodiversity across the Katoomba and Minnehaha Falls Creek.
Local residents lamented the loss of their favourite swimming hole, as the ‘bottomless pool’ at the base of Minnehaha Falls had filled with sediment. A coordinated and collaborative approach with the Blue Mountains City Council, government agencies, businesses and the local community resulted in the successful restoration of Yosemite Creek and the return of the pools including Minnehaha’s ‘bottomless’ plunge pool.
Key to the success of the project has been the long term involvement of a number of Bushcare and Landcare groups in the broader Katoomba and Minnehaha Falls Creek both through on ground action and the coordination of annual sub catchment planning meetings. These groups have, through the leadership of Lyndal Sullivan, provided a well-coordinated approach to catchment management working closely with Council and NPWS through their yearly planning meetings.
The work of the Minnehaha Falls Bushcare Group needs special mention for its unfailing commitment and the positive results it has been able to achieve in significantly improving the health of the bushland and aquatic habitat of this stream.
The same pool – now clear of sediment and staying that way – thanks to bush regeneration (both paid and unpaid) and improved stormwater management throughout the Yosemite Creek catchment.
Over the past century, average land surface temperatures have risen by almost 1° C across the Australian continent. Models suggest this may have already had significant impacts on Australia’s ecosystems and biodiversity in some areas, but these impacts have not been systematically investigated.
CSIRO Land and Water and the Department of the Environment and Energy are undertaking an exciting project to collect stories and anecdotes that will help build a national picture of ecological change (or lack there-of) that has been observed in the past 10-20 years or more. We are looking for people with strong links to Australian environments (e.g. farmers, natural resource managers, ecologists, naturalists) to share their stories for an area they know well, including perceptions of the presence or absence of different types of recent ecological change.
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 will take about 30 minutes – please click here to undertake the survey.
Food A pollinator habitat garden is more than just flower beds. By providing an assortment of plants, which flower throughout the year, you are providing a consistent food supply which will encourage pollinating insects and birds to stay, feed, drink, shelter and even reproduce. It is recommended that you plant swathes or large patches of flowers, rather than scattering them randomly through the garden. By planting flowering food-crops in large patches, you encourage specialist pollinators such as bees to forage within these patches, cross pollinating the plants as they move efficiently from flower to flower.
Shelter The next thing you need to do is provide potential shelter. You can include hollow logs, pieces of thick bark and crowds of rocks which will provide shelter and nesting substrate for a variety of pollinators. Resin bees, leafcutter bees and solitary wasps will nest in large drilled holes in wood, which mimic the natural cavities produced by wood-boring insects. Hollow or pithy stems can be collected and bundled up when plants are pruned. These will attract reed bees and masked bees as well as small solitary wasps and ants. By providing small cavities in rockeries or with layers of rolled bark, you will be providing shelter for ladybeetles, resin bees and other pollinators.
In Australia, gardeners are encouraged to mulch their plants, to maintain soil moisture. However, some of our pollinators, such as solitary bees and wasps, nest in the ground and find it hard to dig through the thick layers of mulch. So leave an area of bare ground, at least a metre squared, to encourage ground-nesting bees into your garden.
Water is necessary for honey bees and birds so include a shallow bird bath, with a large rock in it to reduce the chances of insects drowning. A bowl filled with wet mud will provide minerals and water for some butterfly species and rocks provide insects with a warm place to bask.
Maintenance of your habitat garden is important if the plants and the pollinators are to thrive. Water deeply and regularly to ensure flowers produce plenty of nectar and pollen. Don’t use insecticides. If a plant is infested with many pests, it may need feeding, pruning or pulling out. A healthy garden will not only encourage pollinators, it will encourage wasps, shield bugs, spiders, dragonflies and other natural pest-predators. Keep the water and mud bowls topped up and place a seat out in the garden so you can sit, observe and enjoy your wonderful pollinator habitat garden.
From 1st July 2017 the NSW State Government has replaced the Noxious Weeds Act 1993 with the Biosecurity Act 2015. Under the Noxious Weeds Act all landowners had a responsibility to control noxious weeds on their property. Under the Biosecurity Act the same responsibility will apply and will be known as a General Biosecurity Duty.
General Biosecurity Duty
Under Part 3 of the Biosecurity Act 2015, landowners or land managers have a “General Biosecurity Duty” to prevent, eliminate or minimise the “Biosecurity Risk” posed or likely to be posed by priority weeds.
What is a Biosecurity Risk?
A biosecurity risk exists where priority weeds have the potential to negatively impact on agriculture, industry, the liveability of our city, human health or the environment.
The new name for invasive weeds
Under the Biosecurity Act 2015 invasive weeds are known as “Biosecurity Matter” or “Priority Weeds”.
The Greater Sydney Local Land Services have created a list of State and Regional Priority Weeds with expected outcomes and recommended measures for each species. Council has also nominated Local Priority Weeds that are a problem within the Local Government Area and specified expected outcomes and control measures for these weeds.
The Blue Mountains Bushcare Network proudly to presented their third Bushcare Network Conference on Saturday July 29. This year theme is Citizen Science so a Bioblitz seemed appropriate! The day focused on our beautiful and unique lower mountains vegetation communities. We were fortunate to be able to spend the day with experts to learn how to be “ears and eyes” on the ground. The data we collected will go into data bases for a wider audience.
Concurrent sessions occupied the morning. They included field-based citizen science activities at various locations around Springwood and two presentations at the Hub:
Hollows as Homes – Adrian Davis University of Sydney
Bushcare website update/setup – Hugh Todd
Aquatic Wildlife – Jenny Hill & Fitzgeralds Creek Streamwatch GroupRosenthal Lane, Sun Valley
Birds of the Deanei – Carol Probets & Graham Turner, Deanei Forest Reserve, Springwood
Monitoring the Fauna of Fitzgeralds Creek Catchment – Peter & Judy Smith, Valley Heights Creek, Sun Valley
Plants of Fairy Dell Reserve, Springwood Susan Jalaluddin & Helen Yoxall
The birds group, led by Carol Probets and Graham Turner, observing Bell Miners in the Deanei Forest Reserve, Springwood.
We all reconvened at the Blue Mountains Theatre and Community Hub in Springwood for lunch, informative and inspiring presentations from Margaret Baker and Jenny Hill, and hands on workshops including what to do with the data we collect.
The Hub presentations included:
Birds of Endangered Forests of the Lower Blue Mountains – Margaret Baker
Margaret’s talk introduced the endangered eucalypt forests (Threatened Ecological Communities) that are found on clay soils of the Lower Blue Mountains from Springwood to Hawkesbury Heights and to Lapstone. She described each of the communities, identifiedthe main trees and talked about some of the rare plants, but the focus was the diversity of birds to be found in each of the forest types, especially birds that are listed under NSW legislation as Threatened.
“Citizen Science in Action – what to do with your data” – Jenny Hill
Citizen science has emerged as a distinct field over the last 20 years and is now enjoying a boom. What are some successes? What are the factors critical to its success and what role does Bushcare, Landcare and Swampcare play in this success? How could citizen science grow to be part of the bigger story about restoration and protection in the Blue Mountains? This is brief overview of citizen science is an introduction to group presentations.
In her community volunteer role Jenny Hill is Coordinator with the Leura Falls Creek catchment working group, Bushcarer and Streamwatcher. Jenny has been involved in environmental education and learning for over 35 years and is currently Environmental Educator for Blue Mountains City Council. In this role she conducts citizen science and connects with nature programs across the mountains with schools and community groups. Jenny’s on-ground experience enriched her presentation and provided the bigger picture of citizen science in many different contexts.
Introduction to Biodiversity Atlases on the Internet – Margaret Baker
This talk provided an introduction to the biodiversity atlases that are available on the Internet. It focused on the Atlas of Living Australia – where to find it, how to use it to determine biodiversity in a selected area and how to record data as an individual or as a Citizen Science group. It showed how the kind of data collected in the field sessions of today’s conference can be readily entered into the global exchange of biodiversity information. The world-wide and unrestricted access to such information can however be problematic and so some issues related to atlas and database use was also be discussed.
Members of the Minnehaha Bushcare group were joined by about twenty of Ruth Ley’s friends on Saturday 1st April to celebrate Ruth’s birthday at the Minnehaha picnic area. Ruth was one of the founding members of the Minnehaha Bushcare group and was an active member for 25 years. She was also a founding member of the Katoomba Creek Group and active for 20 years, as well as being an active member of 3 other groups.
One of Ruth’s missions in Bushcare was to rid Yosemite and Katoomba creeks of Montbretia. Her many friends gathered to help continue her legacy in getting revenge against the Montbretia in Yosemite Creek. They also helped to install a plaque in her honour and planted a memorial garden adjoining the Bushcare site. The group would like to thank all of Ruth’s friends who made contributions towards the memorial plaque.
Following many weeks of miserable weather, we were very grateful to be treated to a glorious sunny day to work together and enjoyed morning tea, including date muffins and other goodies. We then shared some of our favourite memories of Ruth, who was a good friend and inspiration to us all. The group plans to continue this tradition on 1st April each year.
It is with a very sad heart that we say goodbye to John. He was dearly loved by his family, cherished by his many friends and his dedication to the community is a loss that will be felt by everyone who had the privilege to know him. I can only imagine part of the loss that his family is feeling and pass on our sincere condolences and support.
I met John many years ago when we teamed up to walk our dogs. I say “our dogs” but really, John was walking his neighbour’s dog as the neighbour did not have time and the dog needed exercise. It was a classic example of the help that John gave without fuss or any strings attached. During these daily walks I not only marvelled at his fitness but also his pride in his family and commitment to the community.
He was a long standing and well regarded member of the Warrimoo Bushfire Brigade. He held many positons in the Brigade and at all times provided non-judgemental support and wise counsel to all members. Many of the members referred to John as “father” as a mark of their respect. The Brigade recognised him as a life member, an award that must be earnt by at least 10 years of meritorious service. John was a more than worthy recipient of this award.
John was an inaugural member of the Cross Street Bushcare and the Long Angle Landcare groups. He regularly attended work days for many years while he was physically able. His dedication and concern for us and the protection of the bushland was appreciated by all. He had a sense of humour that lifted our spirits and we enjoyed his contributions to our conversations at the afternoon tea. We have missed him at the volunteer BBQs held in recent years but still remember his joyous company of past times. I am sure we will continue to contemplate the “good old days” of John’s company of past times for many more years.
There were many other groups that John generously gave his time to. These included the Warrimoo Citizens Association and Warrimoo Tennis Court and Hall Committees. John was also a proud volunteer for the Sydney Olympics. It gave him great satisfaction to reflect on the time that he was the driver for the Israeli athletes and officials. This was a demonstration of John’s character as he enjoyed helping others in need without any expectation of personal reward; the opportunity to help was reward enough.
John and one of his many friends
Many probably do not know that John was also a skilful negotiator. On two occasions, as a result of John’s manoeuvring, I ended up owning dogs that I had not bargained for. On the first occasion after waiting for his chance (it was a well-timed manoeuvre) , John suggested that I take a rescue dog home to see if it would fit into the household. Of course the rest of the story was predictable. On the second, we were at a BBQ and were trying to convince John and Doreen to take on a dog that a family reluctantly had to give up. John was too wily a negotiator for us and when my wife Joan, in frustration said that if no one else wanted the dog we would take it on, he made his move. Before we could change our minds John arranged for the dog to be delivered to us. Of course he knew we were dog lovers and that they would be well looked after. He also knew we were in need of the dogs and so, while he was quick to strike, he also knew that both the dogs and us would benefit from his match making. These ordinary examples of John’s insightful and compassionate nature are a tribute to his character and my fond memories of him.
I have treasured memories of the afternoons that Joan, Doreen, John and I spent relaxing on his porch in pleasant conversation while watching the happenings in the street. John would occasionally greet passers-by and some would call in to catch up. John loved Warrimoo and was surrounded by many dear friends who have had the good fortune to have a shared the life of a modest, genuine, caring man.
To respect John’s legacy, we should strive to continue with his high standards of commitment, compassion, practical help and loyalty that was at all times willingly volunteered. This is the very least that we can do to honour a very dear mate.
Following up on the great success of the Native bee hotel making workshop at the annual Bushcare picnic in April, Bushcare is launching “The Pollinators” group web page … an online tool for everyone to get involved and post what pollinators are in the hotels, any information you have or would like and gain access to recources and events about pollinators – bees, flies, butterflies, birds …
The coordinator for this page is Phil Nelson, I think you will all remember him from the day – very busy with a drill in hand.
So send your information to him via email and he will upload it to the page.
