Seeds are an adaptation to survive unfavorable conditions and to disperse in space and in time, thus playing a key part in the assembly and regeneration of existing and future plant communities. Seed-based restoration harnesses the practicality and diversity of these attributes to revegetate, enrich, or conserve plant communities. This is especially true and important as restoration sites worldwide are increasingly altered and degraded by extreme wildfires, invasive species, fragmentation, mining and climate change. For these situations, seed-addition is essential along with management to achieve restoration goals. The native seed sector has advanced in recent decades, however, there are many challenges and opportunities associated with the use of native plant seeds in restoration. This symposium covers best-practices and current research relevant to obtaining seeds for restoration including seed needs assessment, seed sourcing, seed procurement models, seed collection, seed technology, seed innovations, and seeding and deployment.
