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.

New Book and Exhibition

The green heart of our planet: A journey through the world of trees

This book has been prepared as a catalog of an exhibition at the Forest Culture Center in Gołuchów (Poland), which opened its doors on 4th of June 2021. The main purpose of the book and of the exhibition is to show the beauty, uniqueness and importance of trees to our planet and ourselves.

Ulmus minor
Elm family reloaded!

Global biogeographical and ecological synthesis of Ulmaceae

Yann Fragnière (team of the Botanic Garden of the University of Fribourg) published a new paper entitled “Biogeographic overview of Ulmaceae: diversity, distribution, climatic and ecological preferences” in the journal Plants.

Negative effect of browsing

Exclusion of browsing and conservation of Zelkova abelicea

Laurence Fazan (Zelkova-team of the University of Fribourg) published 2021 a new paper entitled “Free behind bars: Effects of browsing exclusion on the growth and regeneration of Zelkova abelicea” in the journal Forest Ecology and Management.

Biodiversity Conservation and Forest Management - Trends and Perspectives

Special Issue of Forests edited by Dr. Anna K. Jasinska

The geographical ranges of plants in the world depend on many factors. One of the most important over the millennia has been, and is, the climate. The disappearance or expansion of the area covered by woody species as the foundation of forest ecosystems largely affects other species of plants, animals or fungi, and contributes to changes in the microclimate, matter circulation, and others. As a result of climate change, many species are doomed to extinction, and others may seize the opportunity to enlarge the area that they currently occupy. In both cases, scientists and foresters are faced with the challenges of properly preparing for these changes, examining them, trying to predict their effects, counteracting them and supporting selected species in expansion. The aim of the Special Issue will be to explore different aspects of forest ecology and biology, evolution and biogeography of woody plant species.

For this Special Issue of Forests, we therefore warmly welcome contributions (original research papers, reviews, perspectives and opinions) from different fields of research. Forests receives an IF of 2.762.


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.)
