Switzerland's dominant tree species exhibit masting behavior, characterized by irregular, sporadic seed production patterns. These patterns significantly impact tree regeneration and ecosystem dynamics. Environmental factors and climate change influence these patterns. Despite their ecological importance, many phenological networks overlook seed masting. Our workshop aims to unite managers from various phenological networks to establish an ORD protocol for collecting seed mast data. This standardized method can be integrated into existing phenology networks. Researchers, including modelers, physiologists, and ecologists, will benefit from this comprehensive data collection. The curated data will be publicly available on MastWeb's ORD platform, fostering collaborations with global phenology networks.
