Mediterranean meets Eastern Asia

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.

The meeting started with the participation in the 6th Global Botanic Gardens Congress in Geneva. On 27th of June 2017, the members of our networks presented several oral presentations and posters (e.g. on Zelkova sicula and Z. abelicea). The congress in Geneva was followed by a scientific expedition to Western Prealps in order to explore the dendroflora of the the Canton of Fribourg. The participants visited among others the Vanil Noir Nature Reseve, biogeographically one of the most interesting regions in Switzerland.

On the 30th of June 2017 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.

Unique woody species of Eastern Asia

The main focus is put on the East-Asiatic Zelkova species: Z. serrata, Z. schneideriana and Z. sinica and since 2015 the East-Asiatic members of the genus Pterocarya (Juglandaceae): P. rhoifolia, P. stenoptera, P. hupehensis, P. macroptera and P. tonkinesis. The East-Asiatic part of the Project Zelkova and Pterocarya addresses following objectives: (1) Basic and applied research on relict, rare and/or threatened woody species of Eastern Asia (China, Taiwan, Japan, North and South Korea, etc.). (2) Capacity building activities (teaching, internships, exchange of students and young scientists, etc.). (3) Public awareness and outreach (exhibitions, books, workshops, etc.). (4) Iconographic collections (scientific photography, scientific drawings, etc.).
