For over 15 years the McMaster Ecohydro Lab has awarded the #NobelPeatPrize to the authors of the best peatland or peat paper of the year.

It’s that time of year again where we review papers and finalize a list of nominees.

Do you have a fave paper for 2025 you would like us to consider?

Our new paper in QSR, led by Dr. Donna Hawthorne, explores the various successional pathways that the huge peat swamp forests of the central Congo Basin have taken during the late Quaternary. Open access link available until 21 Nov eur03.safelinks.protection.outlook.com?url=https%3A...

Back from a visit to 🇸🇪 🇫🇮 & 🇪🇪!

Enjoyed meeting ecology, biogeochem, and hydrology researchers to talk about #peatland wildfire, restoration, and resilience.

Sweden’s two #NobelPeatPrize laureates (Gustaf Granath, Betty Ehnvall) were in the audience of my Uppsala Uni seminar.

I started working at MAC 30 years ago this week teaching courses for two geography legends: hydrology (M-k. Woo) and biogeography (G. MacDonald). That experience and mentoring from Profs Woo and Rouse helped shape a research career in the emerging (at that time) field of ecohydrology. #BestJobEver

Our latest paper!

Regional Wildfire Smoke Reduces Boreal Forest Carbon Uptake

Smoke-related inhibition of photosynthesis via reduced light availability should be considered when quantifying the net impacts of boreal wildfires on net radiative forcing & carbon balance

New paper out - Regional wildfire smoke reduces boreal forest
carbon uptake

iopscience.iop.org/article/10.1...

Wildfires are a source of carbon and they can reduce the carbon sink from the forest. Cumulative Net Ecosystem Exchange (NEE) shows a big drop in 2011 Day 138 due to wildfire smoke.

Cumulative Net Ecosystem Exchange (NEE) observed at the eddy covariance tower for DOY 128–168 in years 2009–2011. Note the large decrease around DOY 138 in 2011 due to wildfire smoke.

Canada now has over 500 out of control (OC) wildfires (299 Monitored and 208 Actioned =507 OC fires). These numbers are similar to the 2023 record smashing season except this year only half the country is on fire.

Q: How does a peat scientist that enjoys adventure spend the #WorldBogDay weekend?

A: 180+ km of trekking, paddling, MTB, and orienteering across the peaty northern Ontario landscape at the Wilderness Traverse 24 hour Adventure Race.

CBC getting the word out there on peatland wildfire emissions, an increasingly important topic as fire seasons keep getting worse in Canada.

Carbon emissions from Canada's wildfires are spiking. But that's not counting our vast peatlands | CBC News

A new government model to estimate peatland emissions and their impact on climate change could provide a new perspective on the problem — and spark new discussions about solutions.

Area burned in Canada for 2025 is now at 5.6 M ha exceeding the total for the entire 2024 fire season. This fire season is not as bad as 2023 that had 9.37 M ha burned by July 12, 2023. However, 2025 is a very active year with 365 fires out of control and 2 months still left in the fire season.
