The rapid changes in the environment due to human activities and climate shifts pose a significant threat to the habitats of rare and endangered plant species, pushing them closer to extinction. It remains crucial to preserve these species to uphold the functioning of ecosystems. Our objective is to comprehend the impact of traits like seed morphology and physiology in endangered species on their capacity to endure extended storage periods. By investigating the relationship between these traits and seed longevity, especially in habitats like less fertile soils or transitional zones, our aim is to enhance the prioritization of in situ protection or alternative conservation cultures for certain species, as well as those suitable for long-term ex situ storage in gene banks. Additionally, our analysis of habitat features and seed longevity data using Ellenberg indicator values (EIVs) aims to unveil why particular habitats favor short-lived or long-lived plant species. Our focus within Bavaria, Germany includes understanding how species, including those stored in projects like Bayern Arche establish their abundance in specific habitats based on seed longevity and environmental factors. This research endeavors to establish a direct connection between seed viability and essential traits, providing valuable insights to optimize seed conservation strategies and improve species selection for storage in seed banks.
