Dear colleagues, the Organizing Committee of the Joint IUFRO-SECF Meeting "Adaptative silviculture of complex pine stands: challenges for forest persistence", to be celebrated in Madrid on April 2027, has decided to extend abstract submission deadline until 18th October. We remind you the proposed sessions, with some indications of topics that fall within the session's objectives: 1. Vulnerability and adaptive capacity of pine forests Keywords: decay, resistance/resilience to biotic/abiotic perturbances, genetic to adapt pine stands, post-fire recovery 2. Adaptive management of pure and mixed pine stands Keywords: silviculture, eco-hidrology, post-fire regeneration treatments, uneven-aged stands 3. Non native pine species as alternative management strategy Use of non-native pine species from a region in commercial or protective plantations, effects of these established plantations, or the replacement of these pine species with alternative species that are better adapted 4. Browsing as a challenge to forest regeneration in pure and mixed pine stands Browsing in regenerated pine or mixed stands 5. Agroforestry with pine species Also non-wooded forest products in pine stands, or substitutions of pine stands with agroforestry alternatives More information is also available on our page about the program (https://blogs.upm.es/iufro-madrid2027/program/) and the invited speakers (https://blogs.upm.es/iufro-madrid2027/invited-speakers/) featuring a very interesting panel of speakers with international standing.
