| Data note | Bosques Sostenibles publishes no annual report, so only cumulative snapshots exist: more than 290,000 trees and 190 ha in December 2017 (press), nearly 500,000 trees and 201 ha in January 2024 (founder interview), and 1,350,000 trees and 940 ha on its website in November 2026. The jump between early 2024 and 2026 is not explained by any published breakdown. The founding year is inferred from the website's 'más de 52 proyectos desde 2011' and 'más de 15 años de experiencia'; the legal form (SL) comes from a 2022 Ávilared article. HQ is Santander (Parque Científico y Tecnológico de Cantabria), not Madrid. |
