Towards positive synergies and wider horizons – A joint meeting of the International Phytolith Society and the European Association of Archaeologists in Kiel, September 2021


Kiel, 11.11.2020

Dear colleagues,


We hope this email finds you well, despite the challenging conditions the world is facing in the ongoing pandemic.

We would like to update you about the 12th International Meeting of Phytolith Research. We are thankful for your patience and understanding for the silence in the last months, during which we were re-arranging the meeting after cancellation.

The 12th IMPR will be hosted on 8–11 September 2021 (Wednesday–Saturday) by the Institute of Prehistoric and Protohistoric Archaeology of Kiel University in Kiel, Germany. In addition, for those who are interested, scientific excursions will take place on 7 and 12 September 2021 (Tuesday and Sunday).

The IMPR is for now planned as a hybrid meeting, allowing both in-person and remote participation. Updates on the possibility of a live event will follow in early 2021, as corona regulations and travel restrictions in Germany and elsewhere are updated.


News | This year, the IMPR will be exceptionally integrated within the 27th Annual Meeting of the European Association of Archaeologists (EAA). This year’s EAA meeting, titled “Widening horizons”, was scheduled at Kiel University ( Every year the EAA meeting attracts over thousands of scientists dealing with different aspects of archaeology and related fields of study of the human past, building a very broad and diverse platform for scientific discussion. In this frame, the organizers and EAA board are welcoming the phytolith community for an integrated 2021 event. As the organizing committee of the 12th IMPR, together with the IPS board, we consider this a chance for growth, visibility and exchange for the phytolith community.

Sessions | Following a bottom-up approach, the participants of EAA meetings can submit session proposals. In order to follow the IMPR tradition, we already submitted the sessions covering the topics previously announced on the 12th IMPR website. The sessions, labeled “IMPR-session title”, are listed below. In principle, the IMPR-sessions will not overlap with each other. The whole committee of 12th IMPR should be considered session organizer.


  • IMPR - Phytolith identification, classification and morphometry
  • IMPR - Phytoliths as a proxy for palaeoenvironmental reconstruction
  • IMPR - Phytoliths in integrated archaeobotanical and ethnoarchaeological studies
  • IMPR - Phytoliths in geoarchaeology and micromorphology
  • IMPR – Phytoliths biogeochemistry - From phytoliths formation and role in modern plants to new proxies for archaeology and palaeoecology
  • IMPR - Microscopy session: Phytoliths in soil thin sections


Registration and memberships | The logistics of the event will follow the procedures of the EAA annual meeting as explained on the website:

Important: A major change consists in the necessity to create an EAA account to register in order to submit abstracts for contributions and to participate. For the EAA account, the payment of the EAA annual membership is required ( ). However, in exceptional circumstances, this is not mandatory if one participates in IMPR-sessions only. If you are interested in presenting only in IMPR-sessions, and therefore wish to be exempted from the payment of EAA membership, it is necessary to send an email to with subject “EAA membership exemption”, specifying your name, affiliation and EAA membership ID number in the message. To obtain an EAA ID number, you will have to create an account, without proceeding to payment, and to log in and out at We will need this information for the EAA Office which will validate your EAA user account and allow you to register to the Annual Meeting. For participants interested in further EAA sessions in addition to IMPR-sessions, EAA membership should be valid or updated.

Note that to present a contribution at IMPR-sessions, IPS membership is required. To find out your benefits as a member and how to register, check the IPS website at the page:

Deadlines | The registration for the EAA annual meeting is now open. For an overview on deadlines see:

The following dates are particularly important:

  • The call for papers/posters opens on 16 December 2020 and closes on 11 February 2021.
  • The call for travel grants applications opens on 29 March 2021 ( ).
  • The deadline for early bird EAA membership fee is 31 March 2021.
  • The deadline for early bird Annual Meeting registration fee is 6 April 2021.


We hope that this unique format for the 12th IMPR will lead to a fruitful exchange beyond the respective discipline boundaries, while maintaining the possibilities for expert discussion among specialists, and widening our horizons.


We look forward to receiving your contributions and meeting you, both virtually and hopefully also in person!

Best wishes, and stay healthy!
