For everyone who works on topics related to biosecurity risks associated with tree seeds,
we are inviting you to submit an abstract for oral/poster presentation at IUFRO 2024 World
Congress (Stockholm, Sweden, June 23-29, 2024;
https://iufro2024.com/)
Session title: The biosecurity risks of international movement of tree seeds
Session number: T1.32
Session organizers: Iva Franić (SLU, Sweden), Ana Perez-Sierra (Forest Research, UK),
Marie-Anne Auger-Rozenberg (URZF INRAE, France), Thomas Boivin (URFM INRAE, France),
Michelle Cleary (SLU, Sweden), David Kolotelo (BC Provincial Tree Seed Centre, Canada),
Olle Rosenberg (Skogforsk, Sweden)
Session Description: Tree seeds have been considered as a minor introduction pathway for
pests (i.e., insects and fungi) in comparison with seedlings. Consequently, tree seeds are
often exempt from the existing restrictions that aim to mitigate the risk of pest
introductions, although the regulations vary across countries. Tree seeds have shown to
carry pests that may pose immense danger to natural forests and nursery stock with
consequences to forest biodiversity and state’s economy. Some tree seed pests may be
biologically predisposed as good invaders because they can stay dormant for long periods
of time while showing no signs of presence in seeds and thus easily stay unnoticed during
inspections. This however might differ between insects and fungi, and between pests
specialized on angiosperm and gymnosperm hosts. Although the risks of pest introductions
via seed movements seem to be significant, there is a lack of knowledge required for a
proper risk assessment, especially when considering the changes in the global trade
volumes, routes as well as the impacts of climate change. This session aims at gathering
contributions from entomologists, phytopathologists and other seed specialists working
with gymnosperm and angiosperm seeds that might help to improve the assessment of the
biosecurity risks associated with seed trade. More specifically, we aim at covering topics
related to: volumes and directions of international tree seed movements, international
legislation for tree seed exchange, the diversity of tree seed pests, tools and methods
for their detection, as well as the topics related to different aspects of the ecology of
tree seed pests that might be relevant for their introduction, establishment and
spread/impact in times of global change.
Abstracts can be submitted at

We are looking forward to receiving your abstracts and meeting you in Stockholm!
Kind regards,
Session organizers.
