The Canberra grass pollen daily count for 2025 started with a bang and ended with a whimper. - strong grass pollen season began in late September - by mid November the daily counts began to plateaus to reach below average levels by end of December. - only 3 EXTREME grass pollen days were recorded.

The figure depicts the cumulative pollen count curve from October to December 2025 and compares it to all other years with data. The 2025 October to early November counts tracked those from previous above average years (2020-2023). However, by mid November the daily counts began to stabilise to moderate-low levels and the cumulative curve plateaus to eventually reach below average levels by the end of December.

An inset histogram graph depicts the proportion of recorded grass pollen levels (LOW, MODERATE, HIGH, EXTREME) for 2025 compared to El Niño and La Niña years showing that 2025 lies between the proportions that characterise El Niño years vs. La Niña years.

It seems a little early to start talking about the pollen-hay fever season in Canberra, but over the weekend we saw the first hint of elevated pollen levels in Cupressaceae pollen (Cypress pine family) - 14 grains/m3 - still LOW, but hinting at the beginnings of elevated levels to come.

Our latest paper on degradation of peatland systems on King Island (Lutruwita/Tasmania) shows how vulnerable peatlands are under current land management practices. Is the sudden loss if ~4000 years of peat from this site a “canary in the coal mine” for Tasmania/Australia? doi.org/10.1111/aec....

Palaeoecological Analyses Reveal Recent Fires Have Destroyed Late‐Holocene Peat Deposits in Tasmania's Largest Ramsar Reserve

Australian peat-forming wetlands, including those in Tasmania's largest Ramsar reserve—Lavinia State Reserve (LSR), are under threat from climate change, wildfires and human activities. A palaeoecolo....

Who else is presenting at #ICCB2025 ? So many exciting talks and posters in the program! Repost this slide and let us know when / where to find you!

Wondering what was in the air during the dust storm that passed over Canberra this week? Our daily pollen monitoring slide collected on the morning of the 27/5/25 shows the dense brown particles captured over the event. The fine particles of dust can be seen at 400x magnification.

Humans in Africa’s wet tropical forests 150 thousand years ago. The onset of human occupations at Bété I found to be ~150 ka, linking them with Homo sapiens. Plant wax biomarker, stable isotope, phytolith and pollen analyses all point to a wet forest environment. rdcu.be/ebrSR

The summer Elm pollen season is well underway this year with an early start in late January and EXTREME levels experienced over the last few day. Extended and elevated tree pollen seasons in winter and summer are becoming increasingly common in Canberra.

Still can’t shake the sneezing and wheezing this summer? One of the reasons may be the onset of She Oak (Casuarina) and Chinese Elm (Ulmus parvifolia) summer pollen season - a very CBR phenomenon. This year (and last year) we saw a much earlier onset of these allergenic tree pollen in Canberra

Chinese Elm tree or Ulmus parvifolia pollen is increasing in Canberra this week marking the beginning of the late summer-autumn pollen season. If you are experiencing hay fever symptoms this might be the culprit!
