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.

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?

Bogong moths use a stellar compass for long-distance navigation at night

Each spring, billions of Bogong moths migrate up to 1,000 km

They use stellar cues and the Earth’s magnetic field for long-distance nocturnal navigation towards a specific destination.

Does climate play a role in tree longevity?

A paleo study in Georgia suggests that might be a possibility: www.pnas.org/doi/10.1073/...

Fossil pollen from Goat Paddock Crater, Kimberley Plateau, are restricted to the Late Cretaceous Epoch.

Pollen grains from 123 million years ago show the grooved shape characteristic of eudicots. The findings, from the Lusitanian Basin of Portugal, are the earliest known tricolpate pollen and provide insight into the diversification of flowering plants. In PNAS: www.pnas.org/doi/10.1073/...

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.

Great podcast by Madeleine Bessel-Koprek, ANU PhD student, with a fascinating discussion about her research on reconstructing the past vegetation and fire history of Long Island (Tasmania).

Outreach stretching 16,750km to the southern shores of Long Island (New York, USA)!

>50,000-year-old worked tree resin from the Raja Ampat islands, north-west of New Guinea. Resin was used by ancient humans for fire-lighting, hafting tools and constructing boats. This is the oldest example of tree resin processing outside of Africa!

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.

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.
