The Pollinators

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.

And get ready for Pollinator count in November … and some butterfly hilltopping activities …

 

Jamison Creek Catchment: Caring for Dwarf Mountain Pine

Protecting the Wentworth Falls population of the endangered Pherosphaera fitzgeraldii  from the very invasive Montbretia was the name of the game for our Jamison Creek Catchment Care Day this year. It was well received by some keen Bushcare volunteers, BMCC Bushland Operations Team (Bushcare Officers and Bush Regeneration Officers) and the NPWS Ranger for the Jamison Valley.

Having 2 extra Bush Regeneration team members involved for the first time meant we could divide into smaller groups and cover more of the creekline as well as share information about the management of the whole area while we worked.

One group met at Wentworth Falls Car Park, walked to the top of Wentworth Falls and then worked upstream (wading where necessary) to follow up woody weeds in the area worked last year.

The other groups met at the corner of Jamison and Fletcher streets, kitted up and after a short walk down to the creek, with some walking further down the Charles Darwin Track, started target ting Montbretia around the pools and cascades and all woody weeds and the along the track and creek banks. All three groups re-united for lunch and informative talks on the creek bank.

Montbretia is slow going so although the distance covered wasn’t huge, we removed lots of corms and enjoyed the beautiful weather and surroundings while we worked. There was lots of opportunity to discuss the creek condition, learn about the endangered Dwarf Mountain Pine (Pherosphaera fistzgeraldii).

Another target weed in this catchment is Erica lusitanica (Spanish or Portugese heath, often referred to simply as “Erica”, a woody shrub which has a similar appearance to native tea trees so is often mistaken for a native. Both Montbretia and Erica have the potential to establish in the rocky crevices on the cliffline adjacent to the waterfalls – taking up the space where Dwarf Mountain Pine grows. Annual Catchment Care Days are a valuable contribution to the ongoing work of Council’s Bushland Operations Team, contractors and the volunteer Bushcare Groups. Charles Darwin, Jamieson St Landcare, Wentworth Falls Lake, Water Nymphs Dell and Valley of the Waters groups were all represented this year and together we not only dealt with Montbretia and Erica but as Tutsan, Japanese honeysuckle and Small-leaf Privet as well.

Jenny Hill from Council’s Healthy Waterways Team delivered a very informative talk about the issues affecting the water quality of the catchment and the work underway to improve stormwater management.

Good food, good company and good work resulted in a very enjoyable and productive morning – made possible through funding from the NSW Office of Environment and Heritage “Saving Our Species” program. A huge thank you to SoS and the dedicated volunteers of Wentworth Falls!

 

Celebrate 80 years of Bush Regeneration in Broken Hill

Come to Broken Hill this coming August to see where it all started, learn about and celebrate the beginnings of Natural Regeneration in Australia.

In 1937 Albert Morris, his wife Margaret Morris, the Barrier Field Naturalists and 3 Mining Companies made history by starting the first professional scale natural regeneration project in Australia and possibly the world. This was inspired by Albert’s long held dream to fence an area ‘1/2 a mile wide around the town of Broken Hill’ to counter extreme dust storms and sand drift caused by overgrazing.

The Australian Association of Bush Regenerators (AABR) along with local community members is planning a few days of tours, field work and an awards dinner to celebrate this remarkable 80 years.

The idea is similar to other ‘regen holidays’ where visitors can contribute some regen work for two mornings (optional) and locals will run special tours of the reserves explaining the history and current management of this amazing project. After lunch we will be able to visit a range of activities including historical & art exhibitions, movies and a heritage tour.

There are many places of natural beauty to appreciate near Broken Hill as well as its rich union and mining history to explore.

Options for travel will include train, minibus or private cars. The train can be caught from Katoomba. Those travelling on minibuses will be on an organised tour – price details coming later – including an extra field trip on the way (Nyngan waterponding), and van park accommodation and transport within Broken Hill.

More details will be on the AABR website soon www.aabr.org.au If you wish to talk to someone local about the plan, contact Lyndal at the Bushcare office on 47805623 or email lsullivan@bmcc.nsw.gov.au

SWAMPCARE FIELD DAY

Swamp School photo by Paul Vale

A Blue Mountains Swamp near the airfield at Medlow Bath — in its flowering glory — attracted an  enthusiastic group of Swampcare volunteers to a field day in January 2017. The field day was part of a 10 year project to protect swamps, called “Swamped By Threats” whose partners include Central West Local Land Services, Blue Mountains City Council and National Parks and Wildlife Service.

The volunteers enjoyed a morning packed with information and good food topped off by a sighting of Blue Mountains Water Skinks – a well deserved reward for all their work during 2016! Unfortunately, the hoped for Giant Dragonfly did not make an appearance … this was not a good year for their emergence.

Two eminent swamp experts were on hand to generously share  their knowledge deepen our understanding of swamp plants and animals and their dependence on groundwater. Doug Benson is a highly respected plant ecologist and Honorary Research Associate with the Royal Botanic Gardens Sydney. He has studied swamps of the Blue Mountains and Newnes Plateau for more than 40 years, satisfying his curiosity about how and when they developed. Ian Baird drew on more than 13 years of research on the threatened Giant Dragonfly and swamps generally, to share his extensive knowledge of the fauna that dwell in them.

Our current swamps formed up to 15,000 years ago as the land warmed up and became wetter after the last Ice Age.   How the unique swamp plants formed and where they were during these cold and dry periods are particular questions of interest.

Flowering shrubs such as the rare Acacia ptychoclada and Grevillea acanthifolia were admired along with sedges such as Empodisma minus and Xyris ustulata. Two of the shrubs present in swamps, Banksia ericifolia and Hakea teretifolia, are killed by fire because they do not resprout from a lignotuber and do not store seed in the soil. Individual plants can take up to 8-10 years to flower and fruit and even more years are needed between fires to establish a seed bank to ensure the continuation of viable populations of this species in this location.

Plants adapted to sandstone areas only drop seeds close to the parent plant, which is in contrast with northern hemisphere plants where seed moves much greater distances due to reliance on wind dispersal. The presence of Mallee eucalypts in swamps may be understood in terms of opportunities to thrive without the competition of larger trees. Adapted to wetter conditions and fire, some of these Mallees have lignotubers at least 50-100 years old.

Using a 1.8m steel soil probe, Ian demonstrated the significant differences in the depth of soft peaty soil over the swamp and the patches of drier sandy loam. These soil differences are reflected in the plants, and determine where Giant Dragonflies can reproduce.

Ian identified patches suitable as breeding habitat and those which were not, and discussed the importance of damp or saturated peaty soil with a high water table for egg-laying and larval establishment.  It is believed that they then spend at least 6 years in their larval burrow. The deepest larval burrow Ian has found, also the deepest recorded, was 75cm.

A very young Blue Mountains Water Skink, plus two adults were sighted. One adult water skink sat still on top of the grass watching the group for some time. Genetic studies indicate that this species has been in swamps in the Blue Mountains for at least 2 million years, but where were they during the ice ages which have occurred over that time? They are currently solely dependant on peat swamps in the mid-to upper Blue Mountains for their survival.

Blue Mountains Water Skink

Ian gave some insights into the range of less appreciated fauna found in swamps which also need groundwater for survival, from the small invertebrates and skinks which may survive fire under patches of wet litter, to the Common Eastern Froglets, burrowing crayfish and swamp rats. Blue Mountains Water Skinks can sometimes use these burrows, and those of Giant Dragonflies, for protection from fire and predators. Crayfish burrows are found in areas with groundwater seepage or a high water table which they can access in their burrows. Swamp rat tunnels may also be abundant; one of which was inspected (these are more horizontal).

Both Doug and Ian explained how Blue Mountains Swamps are important for holding and filtering water. The conservation of swamps is a key concern of those present and an interesting debate on fire, sedimentation and climate change followed. The predicted hotter, drier conditions and more frequent fires will threaten the swamps’ survival.

This event was organised by Blue Mountains City Council Bushcare and assisted by the New South Wales Government Environmental Trust Fund, NSW Local Land Services and NPWS

Pollinator week in the Mountains – a Buzz of activity !

Bee Hotel workshop – Upper Kedumba Bushcare Group November 2016

Birriban Katoomba High School Landcare, Upper Kedumba Bushcare, Central Park Bushcare and Leura Public School Swampcare all participated in activities to promote and encourage pollinator awareness and habitat.

Upper Kedumba Bushcare group hosted a pollinater habitat (Bee Hotel ) making workshop. Three types of habitats for different bee species were constructed and installed in appropriate places around the site. A simple hanging Bamboo home , an elegant bee box with asorted materials and entry sizes to enhance habitat variey and a sturdy mud home with besser blocks for ground dweling bees, such as our favorite, the Blue Banded Bee.

Some participants also made smaller versions to take home. The group reports that those installed on site already have evidence of happy occupants – within the month !! David Rae installed his “Bee Hilton” which he constructed prior to the day, and reported that he advanced his knowledge of the subject through the workshop. “The production of the clay infill for the blocks was a very useful exercise I think. I have since played around with this at home using a mix of Builders Clay, sand & soil” he said.

The final product!

Philip Nelson spent many hours preparing for the day and having materials ready so the group could simply construct and has written out a comprehensive “how to” information sheet. His advice to those planning a similar event is to construct some hotels first to work out what is best done prior to the day and what are the most suitable tools and materials to use.”

Central Parks Jo Goozeff found a lovely simple way to construct 4 bee hotels out of a hard wood log , these were quickly inhabited by resin bees , cuckoo and mud wasps all fantastic pollinators.

The Birriban Landcare students spent 3 months planning, preparing and making 5 very beautiful bee hotels. The day of installation was marked with a ribbon cutting by a group of school dignitaries and the planting of bee friendly plants in the Birriban habitat garden. Cheekily promoted as “the biggest hotel opening The Blue mountains has seen” the installation warranted an article in the Blue Mountains Gazette.

Leura Public School Swampcare Group celebrated Pollinator week by constructing a mixed material bee hotel in the bushland behind the school. Four students re-used an old wooden Antechinus nesting box as the hotel’s foundations and filled it with lengths of bamboo, various widths of holly stems (previously cut from the site) with holes of various widths drilled into them, tree fern stalks and eucalyptus bark. The hotel was then mounted on a cut stump of dead holly, making further good use of the weeds on site.

Pollinator week participants were surprised to learn that not only do native bees exist, but we have so many species (over 1500) in Australia. Like most people, the only bee species they were previously aware of was the European Honeybee and while honey is most appreciated, the role played by other pollinators is critical to a well-functioning ecosystem and crop production.

 

Bringing Back the Birds in Blackheath

A misty and cold Saturday morning was brightened and warmed by local families at Popes Glen in Blackheath recently. It was an informal idea amongst friends about getting together to spend some time, while getting their kids together and giving them something great to do. Then everyone has a nice bit of morning tea and a chat while the kids run off some more of that energy!

Little people making a Big difference!

Little people making a Big difference!

And what better thing to do in the outdoors than pop down and meet a local Bushcare group?

Well, that is just what a group of friends in Blackheath did. A wonderful little army of youngsters and their equally wonderful families came down to help the Popes Glen volunteers plant out their third Small Bird Habitats.

These habitats are small, strategically placed areas which are then densely re-vegetated with a mixture of native shrubs and ground cover plants. As they grow and develop these plants will form very dense thickets, perfect for providing shelter, protection and food for many species of small native birds which are known to live in Popes Glen.

Surveys have shown us that these small birds are using several large piles of timber debris left on the site after the treatment and felling of several large Willow trees. This fantastic fact demonstrates the ability of a recovering Bushcare site to provide new habitat and resources for native creatures, where in the past those creatures have only seen their habitat diminish.

With the news that the small birds are moving in to Popes Glen for the new habitat came a potential problem. While these debris piles provide the perfect opportunity for small birds to move in, they are not going to last forever. The wood is steadily breaking down into humus. Not so good for birds, but perfect for plants.

And there was the answer to the problem. The Popes Glen volunteers decided to take advantage of the rich soil by planting shrubs which will grow to replace the structure of the piles as they break down. Then the birds which are depending on their pile of logs for their home can watch their new home grow around them, before their old houses fall down!

What a nice way to spend a misty Spring morning!

By morning tea time, Popes Glen had one hundred and forty new plants. They were all guarded, watered and ready to grow into a palace for small birds! There was a wonderful atmosphere of smiling and fun. Everybody had a contribution no matter how big or small! What a wonderful day at Bushcare!

Where would we be without BUBBLES!

Researching the Ecology of the Yellow-tailed Black Cockatoo

Is there anyone who doesn’t appreciate the sight of a flock of Yellow-tailed Black Cockatoos (YTBC) flying overhead ? It seems that very little is really known about them and you can help to change that and potentially influence planning for their conservation.

Jessica Rooke is an Advanced Science (Biological Sciences) student at the University of New South Wales. She is currently undertaking Honours in Ecology with the Centre for Ecosystem Science, supervised by Professor Richard Kingsford, Dr John Martin and Dr Kate Brandis.

Jessica’s project focuses on the well known Yellow-tailed Black-Cockatoo. However, not many people know that this iconic species has been largely understudied, and is in significant decline. The project’s objectives are to investigate the species habitat, foraging and breeding ecology, with an overall aim of creating a management plan to help conserve the Yellow-tailed Black-Cockatoo.

In particular, it would be helpful for you to report any sightings of YTBC (regardless of location) using the online survey which can be found on the Centre for Ecosystem Science website: (https://www.ecosystem.unsw.edu.au/content/conservation-practice/threatened-species/foraging-and-habitat-ecology-of-the-yellow-tailed-black-cockatoo). Further, if you know of any YTBC nesting sites in the Blue Mountains and wider areas that would be extremely useful to researchers investigating the breeding ecology.

If you have any further information, questions or queries, particularly regarding locations of breeding/nesting sites, please contact Jessica: j.rooke@student.unsw.edu.au

Banksia Park Bushcare volunteers recently observed some Yellow-tailed Black Cockatoos boring into Tea trees, apparently to extract wood-boring invertebrates. The group had intentionally planted Hakeas and Banksias to provide a food source for them so we were pleasantly surprised that the Tea trees planted alongside were also providing food for the iconic species! Jessica advises that literature suggests that Yellow-tailed Black Cockatoos increase this behaviour during breeding time, and when juveniles are fledging (around June-July, although this is based on limited studies, and is said to change across their range). If your groups has any similar observation, please take the time to record them and upload the data to the easy to use survey. The more we can contribute to these Citizen Science type projects, the more chances we’ll have to help protect the habitat of the species being studied.
