New publication on Pinus cembra (Pinaceae)

Y. Fragnière, V. Sonnenwyl and B. Clément published new publication in the journal New Forests. The title of the paper: "Large scale afforestation failure with Pinus cembra in Western Prealps." The publication shows results of the Master Thesis of V. Sonennwyl carried out at the University of Fribourg and supervised by Y. Fragnière. The research was done in collaboration with the University of Bern and the Swiss Federal Institute for Forest, Snow and Landscape (WSL, Birmensdorf, Switzerland).

Launch of the Project Ptilostemon

The main goal of the project is to ensure the long-term conservation of Ptilostemon greuteri (Asteraceae), a critically endangered and endemic woody species of Sicily. This phylogenetically isolated taxon is one of rare examples of woodiness among Mediterranean Asteraceae. It consists of only few very small subpopulations occurring on north-facing cliffs and ledges, on Mt. Inici (western Sicily). As the species has been discovered only recently (2006), many aspects of its biology, biogeography and conservation needs are poorly understood.

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.)
