Bosgroep | Ecology of the past

On the 17 and 18 October 2024 the Palynologische Kring (Dutch Palynological Society) held a seminar afternoon and excursion near Apeldoorn in the Netherlands.

During the seminar afternoon (17 October) we heard four talks. The first from Harm Smeenge and Ariët Kieskamp (both Bosgroep) introduced the sites we were to visit on the excursion the next day. This focused on the landscape ecology and ecological history of the bogs on the eastern slopes of the Veluwe. The second talk, by Roy van Beek (Wageningen University & Research), focused on the Celtic field systems around the Veluwe. He explained the latest archaeological and archaeobotaincal work investigating the age and origins of these field systems. The third presentation was by Jasper Candel (Wageningen University & Research) and focused on the geomorphological features from glacial activity in the Veluwe region and how this has effected the development of mire ecosystems. I (William Gosling) gave the final talk, presenting the outputs of the research theses of Sanna Wessel, Chiara Raino and Roos Dik who all completed projects at the University of Amsterdam and worked together to investigate how different mega-herbivore populations in the Dutch landscape were represented by the dung fungal spores preserved in the soil.

The University of Amsterdam (UvA) palaeoecology course is underway. The course is part of the BSc Biology program and the “Earth & Ecology” minor of the BSc Future Planet Studies.

Week 1 (last week) we got everyone up to speed with the fundamentals of palaeoecology (including: key principles, depositional environments, dating methods) and laboratory skills (pollen, phytolith and macrofossil identification). This week (week 2) we are out and about (coring sediments, surveying vegetation and visiting the archaeology department). By the end of the week the students will (should!?) have generated sufficient data in the laboratory and field to be able to identify the location from which their mini-project “mystery slides” were taken. Next week (week 3) will be number crunching to generate the statistical support for their ideas and inferences.

Students collecting sediments using a Russian corer at Langenboom (September, 2022). These samples were recovered in collaboration with the BosGroep Zuid Nederland as part of an ongoing project to gain new insights into the nature of the past landscape in the Netherlands and aid conservation efforts.
