This Special Issue of Reforesta, International Practices for Regenerating and Restoring Forest Trees by Seeding, brings together regional practice and research from North America, South America, Europe, Asia, and Oceania on using broadcast and direct seeding to create forest cover. It presents a significant range of seeding activities inclusive of species, forests, sites, and climates. Seeding has regained interest because of its scalability and cost-effectiveness, particularly for remote or inaccessible areas, sites with low productivity where planting seedling costs are prohibitive, or when aiming for a more natural forest structure. Technological innovations, particularly in seed treatments, automation, and precision seeding improve success of large-scale seed dispersal.

Seeding pines in the Mediterranean region

Extensive disturbance to the ecologically, socially, and economically important pine (Pinus spp. L.) forests of the Mediterranean region has created a strong need for forest restoration throughout the region. Seeding could potentially be a viable option for regenerating some of the 10 pine species that occur in the region, especially the fire-adapted serotinous species, but previous seeding efforts have been marked with inconsistent success. From our synthesis of available literature and practical experience, we briefly summarize the history of applied trials and pine seeding research, examine the factors that determine pine seeding success, and discuss what we have learned that can make seeding an ecologically and economically viable approach to pine forest establishment in the Mediterranean region. Future refinement of autonomous drones for seed delivery, selection of favorable sowing microsites, and improvement of seed coating technologies that minimize seed predation and support seedling establishment will support “precision restoration” practices that promise to advance pine seeding to an operational scale in the Mediterranean region.
