Elevated Cupressaceae pollen appear a week earlier than reported last year (2024). Overall, a wet winter this year and the prospect of above average rainfall and warm temperatures in the September to November period (BOM forecast) point to a challenging hay fever season ahead.

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.

See the full paper here, led by Matthew Adeleye, with images of remnant pedestals left after the peat fires.

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....

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?

Was extinction of New Zealand's avian megafauna an unavoidable consequence of human arrival?

Using process-explicit ecological models, the authors show that Moa persistence was not compatible with even low rates of hunting.

Hazy morning in eastern NSW as outback dust reaches Tasman Sea A huge dust storm whipped up in South Australia on Monday has swept over Sydney and other areas of NSW on Tuesday morning.

The dust originated from drought-stricken parts of SA and VIC as a strong cold front past over SE Australia. Observations from Canberra Airport reported haze overnight, with visibility reduced to 5-6 km for more than one hour as the dust blew over the ACT.

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.

Ancient pollen reveals stories about Earth’s history, from the asteroid strike that killed the dinosaurs to the Mayan collapse Palynologists who study tiny pollen fossils share 4 stories found in grains that fell hundreds to millions of years ago.

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.

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!
