Dear colleagues, Within the frame of the next IUFRO World Congress (Salt Lake City, October 5-11, 2014, http://iufro2014.com) we are organizing a Technical Session on "Multiple Risks Management in Planted Forest" (Session N°135) under the congress theme "Forest Health in a Changing World". We would like to invite you to submit an abstract for a presentation to this session. We are particularly interested in presentations addressing interactions between multiple biotic or abiotic hazards (e.g. storm and bark beetles, drought and defoliators, etc.) that can affect planted or plantation forests. We plan to publish a special issue for this session in the online open-access forestry journal "Forests" (http://www.mdpi.com/journal/forests) The editor of the journal has kindly offered to publish 5 papers free of charge for this issue. We hope that the topic will be of interest to you and that you will be keen to submit an abstract to this session. * **The deadline is approaching, don't miss it: October 15, 2013!* Very best regards, The organizers Hervé Jactel, Christophe Orazio, John Moore -- Hervé JACTEL Directeur de Recherches Laboratoire d'Entomologie Forestière & Biodiversité Laboratory of Forest Entomology & Biodiversity UMR BIOGECO - INRA 69, route d'Arcachon 33612 CESTAS cedex, France Tel + 33 - (0)5.57.12.27.39 Fax + 33 - (0)5.57.12.28.81 http://www.pierroton.inra.fr
