Ecology of the past

The June 2023 meeting of the Dutch palynological society (Palynologische Kring) took place at the offices of the Dutch National Cultural Heritage Agency (Rijksdienst Cultureel Erfgoed) in Amersfoort. The focus of this meeting was the past forest landscape of the Netherlands. The meeting included the annual report of the society, three scientific talks, and a prize giving for the best MSc thesis.

The annual report of the society showed a healthy finances and membership (>100 members). Two key events from last year were the award of the societies highest award, the Jongmanspenning, to Margaret Collinson for her massive contribution to the field, and the annual excursion; in 2022 this was to Leiden and included visits to Roman archaeological sites.

The scientific part of the meeting was kicked off my Roy van Beek who presented results from his ongoing project on the peatlands of the Netherlands which suggest peatland expansion occurred between 5500 and 3500 years ago (van Beek et al., 2023). The second talk was by our host, Otto Brinkkemper, and traced the history of woodlands across the Netherlands on the basis of macrofossil finds; including huge tree stumps remarkably preserved in peatlands (Bazelmans et al., 2021; Kooistra et al., 2006). The final talk was given by Jos Bazelmans who showed the remarkably high volume of tree stumps that have been recovered from the Netherlands, and how tree rings from these 100s of record are being used to reconstruct forest histories and past climate change. It was interesting to hear that the average age of the tree stumps found was around 250 years, and that some of the trees had lived to around 400 years in exceptional cases.

The final section of the meeting was the prize giving. Corrie Barkels, on behalf of the independent judging panel, announced Kelly van Leeuwen as the winner for her thesis entitled “Using soils samples and footwear to improve forensic palynology”. Her thesis was conducted at the University of Amsterdam as part of her MSc Earth Sciences degree and was conducted in collaboration with the Netherlands Forensic Institute. Congratulations Kelly!
