Sanctuaries help protect bilbies from cats and foxes, giving the vulnerable marsupial a chance to survive. And it's working! #30DayChartChallenge

Greater Bilby Populations in Sanctuaries. The latest Australian Wildlife Conservancy’s Annual Bilby Census estimates there are about 5,330 total bilbies in their sanctuaries. This estimate includes about 1,834 bilbies at the Scotia Wildlife Sanctuary on Barkandji country in far western NSW as well as bilbies across 5 other sanctuaries. A visualisation. 1 circle = ~10 bilbies. Yellow dots are Scotia Wildlife Sanctuary. Blue dots are 5 other sanctuaries. The counts grow year by year from 1230 bilbies in 2021 to 5330 in 2025.

What Are Neglected Tropical Diseases (NTDs)?
Neglected tropical diseases are a group of conditions caused by viruses, bacteria, parasites, fungi and toxins, and can cause significant disfigurement, disability, and death.
They include preventable and treatable diseases that affect more than 1 billion people globally, especially impoverished communities in tropical regions.
These diseases are “neglected” because they’re barely present on the global health agenda. Limited resources are dedicated to tackling them.

The World Health Organization's List of Neglected Tropical Diseases: Buruli ulcer; Chagas disease; dengue and chikungunya; dracunculiasis; echinococcosis; foodborne trematodiases; human African trypanosomiasis; leishmaniasis; leprosy; lymphatic filariasis; mycetoma, chromoblastomycosis and other deep mycoses; noma; onchocerciasis; rabies; scabies and other ectoparasitoses; schistosomiasis; soil-transmitted helminthiases; snakebite envenoming; taeniasis/cysticercosis; trachoma; yaws

Have We Eliminated Trachoma in Australia?
Trachoma is a preventable eye infection that can lead to blindness. Australia's the only high-income country that has trachoma.
A couple of years ago, we reached the World Health Organization's threshold for “elimination as a public health problem”. The prevalence is really low now. So long as our trend of squashing it continues, we'll be able to declare it eliminated.
2025 could be the year!

These days you can look up hourly air quality measurements online for a bunch of places, but those numbers won't help you with your cooking. #30DayChartChallenge

Total Dust Emissions Across Australia
Airborne soil particles are worse in summer where ground is dry and there's less vegetation cover compared to winter.
A grouped bar chart of amount of dust in tonnes per hectare to June 2020 grouped by Emission, Dry deposition, and Wet deposition shows the highest emissions from Nov to Jan around 3k tonnes per hectare. Dry depositions are also much higher than wet depositions.
Data: Emmerson KM & Keywood MD (2021). Australia state of the environment 2021: air quality, © Commonwealth of Australia, CC BY 4.0, https://soe.dcceew.gov.au/
Chart: @DiDoesDigital

Dust Travels Everywhere
From July 2019 to June 2020, the estimated total dust emissions in Australia was 40 tonnes per hectare.
Dust that's swept into the atmosphere ranges from smaller than 2.5 micrometres to hundreds of micrometres.
The larger particles cause visibility issues and filthy solar panels. They “deposit” onto the ground swiftly, meaning they don't get to travel far.
The smaller particles, however, stay in the air longer and can waft thousands of kilometres onto cities far away.
Source: Emmerson KM & Keywood MD (2021). Australia state of the environment 2021: air quality, © Commonwealth of Australia, CC BY 4.0, https://soe.dcceew.gov.au/

Dust Can Be Gross
Airborne dust can muck up your respiratory system. Mineral dust contains metals like iron that cause lung inflammation.
Thanks to the extra droughts and bushfires from climate change, we’re likely to see an increase in the number of dust days too.
Vegetation programs might help keep the dust down.
Australia generally has great air quality, except during specific events like dust storms and bushfires. There’s increasing demand for real-time air monitoring to help people know when to close the windows or mask up.

Down under, you can use the Southern Cross to tell time and direction. Aboriginal Australians are among the world's first astronomers. The southern cross forms part of the Emu in the Sky, a dark constellation, which has featured in storytelling for thousands of years. #30DayChartChallenge

Find South Using the Stars
In the southern hemisphere, you can use the Southern Cross (aka “Crux”) and The Pointers constellations to find South.
The chart of the Southern Cross and The Pointers shows a line drawn from the highest star of the cross, Gracux, through the lowest star of the cross, Acrux, and another line drawn perpendicular from Alpha Centauri and Beta Centauri, and the two lines marked as roughly south, not far from where the South Pole is marked.
Chart: @DiDoesDigital

Check the Star Clock: Part 1
Imagine a 24-hour clock face. Around 1st April, Crux appears high in the sky at midnight. At the 20 hour mark, it's ~8pm.
The 24-hour clock face has 0 at the top, labelled (midnight), 6 to the right, 12 at the bottom, labelled (midday), and 18 to the left. The Southern Cross constellation is positioned at the 20 hour mark with repeating, fading copies of it clockwise indicating the direction of travel. The chart is labelled 1st April  8pm.
Chart: @DiDoesDigital

Check the Star Clock: Part 2
For each month after April, take 2 hours. At 1st May, if Crux is at the “20” mark, subtract 1 month × 2 hours to get 18: ~6pm.
The 24-hour clock face has 0 at the top, labelled, 6 to the right, 12 at the bottom, and 18 to the left. The Southern Cross constellation is positioned at the 20 hour mark. An arrow points anti-clockwise, labelled "Subtract 2 hours". The chart is labelled 1st May 6pm.

You Can Find South and the Time!
Around 1st June, when Crux appears at the “6” hour mark, subtract 2 months × 2 hours to get 2, which means it’s ~2am.

Our Geological Heritage is Precious
Geoheritage helps define Australia through its iconic landscape. Our geoheritage has significant aesthetic, cultural, economic/tourism, and environmental value. It also informs our future climate.
Like biodiversity, geoheritage is a form of natural heritage but benefits from separate recognition. For example, it requires different conservation strategies to plants and animals.
Australia has an old and stable land mass, so we have heaps of preserved geological features rarely found elsewhere.
McConnell A, Janke T, Cumpston Z & Cresswell I (2021). Australia state of the environment 2021: heritage, independent report to the Australian Government Minister for the Environment, Commonwealth of Australia, Canberra, DOI: 10.26194/7w85-3w50.

Tasmania Has Special Old Rocks
Tasmania is a global geodiversity hotspot with rocks of every geological period from the Mesoproterozoic.
Unlike most of Australia, Tasmania keeps a nice record of geoconservation sites. You can find info about:
- 39 globally significant sites
- 26 rarities
- 32 outstanding references
Entries in the Tasmanian Geoconservation Database also include the geoconservation values the sites encompass, their significance to conservation, their sensitivity to disturbance, and advice on site management.
Data: Natural Values Atlas (www.naturalvaluesatlas.tas.gov.au), 21 Apr 2025, © State of Tasmania · Analysis: @DiDoesDigital

Can We Protect Our Geoheritage?
The pressures having the greatest impact on geoheritage include:
- “Inadequate resourcing for heritage conservation/management.”
- “Inadequate protections (poor statutory controls and poor governance)”
The highest priority action to improve the management of geoheritage is:
- “Improved recognition, including at the statutory level, and moving beyond land-based-only heritage”
Vote for representatives who pledge conservation action.

I went on a lot of side quests in pursuit of a more complex and interesting chart than this but they mostly didn't pan out. Here's a simpler but shinier visualisation instead. According to the ABS, lots of Aussie businesses cease trading in the December quarter each year. #30DayChartChallenge

The Green Catbird's genus name is Ailuroedus, from the Greek for "cat-singer" or "cat-voiced". Instead of "Good morning", it says, "heeeir-Ieee-aaa-aarr!" #30DayChartChallenge

Times I've Heard a Catbird Wail
The Green Catbird is territorial and likes to attack its reflection in my bedroom window.
5:30 AM. How dare you.
The circles for times of day a catbird wail is heard ranging from 5:30 AM to 6:31 PM, with overlapping circles between 6:40 AM and 7:08 AM as well as between 4:35 PM and 4:54 PM.

The meaning of "mateship" can be positive or a bit spicy and has changed over time. Have a read of the Wikipedia page, especially the section on "mate": en.wikipedia.org/wiki/Mateship Mate. #30DayChartChallenge

Interest in Mateship Trending Down
The Google search interest in the topic of “Mateship” is trending downward since its last peak in May 2005.
Interest on the Y axis ranges from 0 to 100
Dates on the X axis range from 2004 to 2025, with tick labels for 2005, 2010, 2015, 2020 and 2025.
The interest is very spiky year to year with few peaks and dips each year without an obvious recurring pattern. Until 2010, interest tends to score between 30 and 100. After that it's mostly below 40, except for large spikes in March 2010 at 50, April 2015 at 57, and April 2020 at 61. It's remained below 26 since 2020.

Numbats used to be all across mainland Australia but by the '70s there were only about 300 individuals in Western Australia. We've done well to control predators and improve fire management but they still need our help! www.numbat.org.au #30DayChartChallenge

Numbats Eat 15,000+ Termites a Day
The adorable, stripey numbat only eats termites, which are not very nutritious so they have to eat a lot to stay alive.
15,000 tiny termite icons packed in.

There are only ~1,400 left in the wild
Numbats are preyed upon by invasive foxes and feral cats. Fires and land-clearing cause loss of habitat. Collection of firewood also depletes important shelter sites for numbats.

Numbats are unique marsupials
Awake in the day
Termites only move to the surface when the ground warms up during the day. Because numbats only eat termites, they have to be awake then. They’re one of the only marsupials active solely during the day!
Long tongues
Numbats have a long, slender sticky tongue around 10–11cm long to slurp up their lunch.
No pouches
Unlike other marsupials, numbats also have no pouches!

Auslan (Australian Sign Language) is a natural language and visual language using hand shape, orientation, location, movement and expression. Apparently Australian Indigenous sign language is not only used by people with hearing loss: many Indigenous languages are multi-modal! #30DayChartChallenge

Auslan vs Steno Fingerspelling
Australian Sign Language fingerspelling vs stenographic fingerspelling and the English alphabet
The letters a, b, c shown in Auslan gestures, stenographic keyboard layout, and English.
The Auslan fingerspelling sign for "a" is Left hand FIVE handshape with palm facing back and right hand ONE handshape with palm facing forward, touching pointer to left thumb-pad. The fingerspelling sign for "b" is both hands OK handshape with palms facing each other, touching both hands pointer and thumb tips together. The fingerspelling sign for "c" is right hand OPEN CIRCLE handshape with palm facing to the left.
The stenography keys for fingerspelling "a" are A and asterisk. The steno keys for "b" are P, W, and asterisk. The steno keys for "c" are K, R, and asterisk.

About Auslan and Stenography
Auslan (Australian Sign Language) is the sign language used by the majority of the Australian Deaf community. It’s a natural language distinct from spoken or written English. The two-handed manual alphabet in Auslan is used to fingerspell proper nouns, technical terms, and words for which there is no widespread sign: maybe around 10% of conversation.
A machine stenographer presses multiple keys together like playing a piano chord to produce whole words at over 200 words per minute. Key combinations usually correspond to sounds like “ch” or the “oi” sound in “ploy” rather than individual letters. When a whole word cannot be written, however, a stenographer may use fingerspelling instead to type the word out 1 letter at a time.
Auslan and stenography both offer ways to communicate at conversational speeds using your hands!

You can tamper with Git history by using `--date=<date>` to change the "author date". For example: git commit --amend --date="Wed Apr 9 22:00 2025 +1000" --no-edit My commit dates are usually skewy from interactive rebasing. #30DayChartChallenge

A Git Commit Date Is Not the Same as the Author Date
Here are my commits over a period of 150 days and the delay in days from authoring to committing. History diverges!
The chart shows commits as violet lines spread evenly over the X-axis. The length of the lines represents the delay in days from authoring to commit up to 2 days. There is one clump with many commits delayed by hours. There are 2 separate commits that have a large, 2-day delay.

Thankfully category 5 cyclones are uncommon, but did you know cyclones Monica (2006) and Marcus (2018) reached rather terrifying sustained winds of 250km/hour? Thank goodness they don't generally make landfall at category 5! #30DayChartChallenge

Most Aussie Cyclones are Category 2
The histogram shows 135 category 1 cyclones, 162 category 2 cyclones, 138 category 3 cyclones, 101 category 4 cyclones, and 61 category 5 cyclones.
Note: The number of cyclones since 1974 at each category are calculated from estimated maximum mean wind speeds over 63, 89, 118, 160, & 200km/h, respectively.

Lismore (NSW, Australia) doesn't usually get as much rain as I imagine it does. The memorable floods of recent years are striking anomalies. The highest flood on record in Lismore was on 28 February 2022, when the flood level reached 14.4m. #30DayChartChallenge

Lismore doesn't always flood
The total rainfall in Lismore each month over 22 years shows how unusually high it's been in recent years.
The line chart shows overlapping lines for 22¼ years of rainfall with higher rainfall during Summer and March. The high points for 2020, 2022, 2017, and 2025 are annotated. They range between 500mm and 900mm. All the other values are below 400mm.
Note: The data is mostly from Lismore Airport AWS. 16 missing values are filled using data from nearby Tuncester and McLeans Ridges sites.

The latest theme for the 30 day chart challenge is "Florence Nightingale". I gave the "Nightingale rose chart" a whirl and I don't like it! While it may be fun to look at, it's not particularly effective for reading. I certainly like it better as data art without labels. #30DayChartChallenge
