You are cordially invited to participate in the International Scientific Conference “Relict woody plants: linking the past, present and future” organized by the Institute of Dendrology of the Polish Academy of Sciences in Kórnik in collaboration with the Zelkova/Pterocarya team of the University of Fribourg (Switzerland) in Kórnik on June 19th, 2018. The aim of this conference will be to present the latest results of research in the field of phylogeny, paleobotanical research, taxonomy, phylogeography, dendrochronology, mycology and species protection, including biology of reproduction and storage of genetic resources. In addition to summarizing the current knowledge and exchange of experiences and ideas, the conference will also enable to use current knowledge in the protection of rare and endangered taxa of southern Europe and southeast Asia. Furthermore, it will facilitate sketching future directions and perspectives of research, including interdisciplinary research and allow for integration of international centers and scientific environments.

The island of Cuba: a jewel of biodiversity

During October 2017, an expedition was carried out, in order to document both subspecies of Juglans jamaicensis, two of the most endangered and extraordinary members of the Juglandaceae family. With the help of local guides and forest specialists, we discovered an astonishing biodiversity and some small populations of J. jamaicensis in Viñales National Park in the west, and in the Escambray Mountains in the center of the island. Juglans jamaicensis is very scattered and needs urgent conservation action programs both in situ and ex situ.

Project Zelkova abelicea - 2017

In 2017, the Zelkova abelicea conservation project entered a new phase after the completion of the initial phase that ran from 2014-2016. During this second phase, the applied conservation actions and efforts were pursued and adapted. There are now over 30 fenced areas containing Z. abelicea individuals throughout all the mountains of Crete.

Xiaolong Mountain
Pterocarya forests in Xiaolong Mountain (China)

Xiaolong Mountain National Nature Reserve is located in the western part of the Qinling Mountains (Gansu province in Central China). In August 2017, an expedition took place, in order to explore the Pterocarya forests of this area. It was organized and coordinated by Yi-Gang Song, our PhD student at the University of Fribourg and at the Shanghai Chenshan Botanical Garden. Vast virgin forests with large pure Pterocarya hupehensis stands, have been found and studied during the expedition. Additionally, two further Pterocarya species (P. macroptera and P. stenoptera) have been observed in this area, mainly along rivers.

Workshop and Symposium in Switzerland (June 2017)

Between the 26th and 30th of June 2017 a workshop organized by our Zelkova-team took place in Switzerland, gathering the international partners and members of our research and conservation networks of Pterocarya and Zelkova. At the end of the meeting a symposium entitled “Mediterranean meets Eastern Asia – international and interdisciplinary cooperation in research and conservation of relict trees” took place at the Botanic Garden of the University of Fribourg in collaboration with the Natural History Museum Fribourg (NHMF). Invited speakers from Switzerland, Italy, Poland, China, Vietnam and Japan presented their research projects and conservation actions carried out in different countries and regions of Europe and Asia.


Our research and conservation activities

  1. Basic and applied research on relict, rare and/or threatened woody species (biogeography, conservation biology, phylogeny, phylogeography, population genetics, population structure, dendrochronology, etc.).
  2. Conservation actions (in situ and ex situ conservation), action plans and conservation status assessments.
  3. Capacity building (teaching, internships, exchange of students and young scientists, etc.).
  4. Public awareness and outreach (exhibitions, books, workshops, etc.).
  5. Iconographic collections (scientific photography, scientific drawings, etc.)
