Short film on Taiwan – Zelkova serrata, landscapes, rare plants and animals.

The short movie (8 minutes) was realized using film material collected during our expedition to Tawian in 2013. The main aim of the field work was to find natural populations of Zelkova serrata and its enigmatic subspecies Z. serrata subsp. tarokoensis (shown in the movie: 2:20-2:40). The movie shows also fascinating landscapes of this pacific island, as well as many other interesting plants and animals.

Extension of the Project Zelkova: genus Pterocarya & Juglandaceae

Since 2015 an extension of the Project Zelkova was elaborated in order to explore and protect other genera and families of relict trees. The main focus is put on the genus Pterocarya and on the family Juglandaceae.

Field course and workshop on Sicily (9th-16th of May 2015)

The University of Fribourg (Switzerland) in collaboration with the Institute of Biosciences and BioResources of the National Research Center in Palermo (Sicily), organized an interdisciplinary and international field workshop on biogeography and relict woody species of Sicily.


Project Zelkova addresses five main objectives

  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.)
