| Data note | ARBA publishes no consolidated annual planting totals. The only organisation-wide figure is an undated statement on its Restauraciones page that in 'thirty years' (i.e. about 2016) it had planted just over 250,000 native trees and sown more than three million seeds. Local groups publish their own activity reports (ARBA Albacete-Chinchilla 2020-2022, ARBA Educa 2019-2022, ARBA Valladolid 2018) that list individual plantings but no aggregated counts. The 2,000 figure is current membership, not a volunteer count. |
