40 Volunteers turned up to Maple Grove, Katoomba for the annual Clean Up Australia event to help remove the rubbish recently deposited by the large rainfall event in February. Aunty Sharyn and David King welcomed us and talked of why this yearly event is so important to the health of the system and the Community. David has been involved with Clean Up Australia since the early beginnings of the program.
The group collected a huge amount of rubbish and felt a great sense of achievement keeping the rubbish out of the Kedumba system whilst gathering with members from Scenic world and the Blue Mountains World Heritage Institution.
And then off course we had a delicious morning tea. See you there next year!
A very large Gully Oreades Roost tree (Eucalyptus oreades) came down in April during a windstorm. Council’s Natural Area Operations team made the area safe and cut the old tree up into usable pieces for use in Middle and Top Swamp for erosion control, water retention, habitat and organic matter.

Some of you may remember when Kirsten Cowley came and talked to Garguree about her PhD which involves assessing the physical attributes of upland swamps, such as water quality, carbon sequestration potential and sedimentology and how these attributes change along a geomorphic degradation spectrum. (To read more see link below).
The fallen Oreades are used to form check dams across the contour lines to slow down water movement across the swamp. These sediment control measures will contribute to the health and resilience of the swamps in ways that were outlined by Kirsten in her talk (attached below a short explanation of her research methods) by placing more organic matter into the systems and slowing the flow of water.
Recently found in a couple of sites around Blackheath has been the weed Datura stramonium or Common Thornapple belonging to the nightshade Family Solanaceae. It has been noticed on sites adjacent to former agricultural land that has been disturbed by recent fires. Such behaviour lends credibility to the long viability of seeds of this species. Additionally it has been noticed producing seed while quite young.
Common thornapple is a short-lives plant that grows in disturbed sites. It is a stout herb, glabrous or sparsely hairy with non-glandular hairs. Flowers are white-lilac 6-8 cm long. Seed capsules are large and oval shaped with numerous spines varying in lengths.
The plant has a strong smell, reminiscent of Green Cestrum, a white flower and grows to about one metre.
Thornapple is highly toxic to humans, capable of causing serious illness or death. All parts of the plant, particularly the flowers, seeds and nectar are poisonous, causing thirst, increased temperatures, rapid pulse, incoherence and convulsions.
The entire plant is also poisonous to livestock and pets.
What to do if poisoning occurs:
If the patient is unconscious, unresponsive or having difficulty breathing dial 000 or get to the emergency section of a hospital immediately.
If the patient is conscious and responsive call the Poisons Information Centre on 13 11 26 or your doctor.
If going to a hospital take a piece of the plant for identification.
Have you seen dead or dying trees in your area? Go to the “Surveys” section and choose “Add a record”. You can then upload photos of your trees and answer a few questions to help identify the possible causes. You’ll find some information about each of these causes in the “Resources” section. Here are some photos from B Medlyn.
How tough are Australian trees? We tend to think of Australian trees as being pretty tough – well-adapted to drought and high temperatures. Research shows, however, that most tree species have a fairly tight ”safety margin”. That is, their adaptations enable them to survive typical droughts in their native environments, but more extreme droughts are likely to tip them over the edge. In Australia, widespread tree death has followed intense drought in some places such as river redgums along the Murray, and jarrah forests in WA.
Records needed For most other forests around Australia, we don’t know what levels of drought they can survive. During the Millennium Drought, there are very few records of trees dying from drought – but is that because few trees died, or because no-one made records? We do know that many of the trees around Cooma died in the years following the Millennium Drought, but scientists are uncertain of the cause because no-one knows when the trees started to die.
How you can help Taking photos of dead and dying trees to record where and when trees die in your area will help scientists trying to work out the level of drought that different species can tolerate. You can send in photos via the website or by email. Trees can die for a lot of reasons besides drought, so the survey asks a few questions to help work out the likely cause of your trees’ death. You might also like to check up on the trees over time to see if they recover.
What will happen to the data? The data will be stored in the Atlas of Living Australia main database. The records will be freely available, so that everybody will be able to track tree death in their area. Scientists will combine these data with weather data to work out the severity of drought likely to cause tree death in different areas. Results using the data will be published on the Dead Tree Detective blog, in scientific publications and in the media.
The recent bushfires throughout Australia have resulted in a variety of reactions from the community. As the immediacy of the devastating effects on communities and bushland diminish, a genuine concern has emerged for the fauna and flora of our burnt bushland. Read more
AABR are seeking your seedling photos and expertise!
The post-fire recovery has reached a phase where targeted weed removal is now possible to aid the native flora in gaining a dominant position in the landscape, creating healthy and diverse habitat.
Seedling growth and resprouting is well underway in many areas, seedling recognition resources are now being developed and we need your help! However (because of the COVID-19 restrictions) it now needs to be done by individuals working on their own properties.
If you use Facebook and have seedling or resprouting images to share, or expertise in identification, please join in and be an enthusiastic participant in AABR’s Seedling recognition Facebook group. AABR is also seeking quality images for inclusion in video and educational resources to support landowners with post-fire recovery.
Photo usage: By posting the images to the facebook group or sending them through to AABR you would be agreeing for AABR to use your images for educational purposes on our social media platforms and website.

Answers to Week 3 Native Birds of the Blue Mountains Crossword Puzzle
Are you wanting to be part of this “Blue Mountains Frog Search” citizen science project?
The ‘Blue Mountains Frog Search’ citizen science program aims to monitor three key threatened frog species around the Blue Mountains region using acoustic data loggers. These data loggers will be installed near waterbodies across various sites and allow for the detection of frog species using their unique calls. As part of the project, citizen scientists have the opportunity to manage an acoustic data logger (including installation, maintenance and retrieval), as well as learn how to identify the unique calls for each frog species and analyse the data collected. Training will also be provided in the use of mobile phone apps, such as ‘iNaturalist’ and ‘FrogID’.
Online training is currently being provided via Microsoft Teams, however this will be extended to include face-to-face workshops and field trips in the coming months. If you are interested in becoming involved in the project or would like to know more, please contact Alana at Alana.L.Burton@uon.edu.au or on 0448 462 004.
