Tórtoles de Esgueva is a municipality in the province of Burgos, Castile and León, Spain, situated at 930 meters above sea level on the limestone moorland of the Castilian plateau. The soils are basophilic with calcium carbonate stones, and the native vegetation is dominated by Quercus ilex forest, with scattered Juniperus thurifera and shrub species including Rosa canina, Prunus spinosa, and Rhamnus saxatilis. The project site had been under dry-land cereal and legume cultivation for over 70 years, replacing a native Quercus ilex forest. This land use was ecologically unproductive and reliant on agrochemicals. The plantation aims to restore native forest cover through a sustainable truffle-producing agroforestry system, delivering benefits including soil restoration, carbon storage, elimination of agrochemical inputs, and long-term economic value through Tuber melanosporum production. Plantation updates: - Planting date: March–April 2025. - 1,600 trees planted, of which 984 trees sponsored by Go Forest clients: 100% Quercus ilex, mycorrhized with Tuber melanosporum, at 400 plants/ha over 4 hectares - Seedling quality: Two-year-old mycorrhized seedlings from Viveros Fuenteamarga (Valladolid), with a mean height of 36 cm, mean stem diameter of 6.8 mm, and an average mycorrhization rate of 29%. - Site preparation: Cross subsoiling and shallow tillage, with a 5 x 5 m planting spacing. Fencing and an irrigation system were installed to mitigate wildlife browsing risk during establishment. - Maintenance planned: A 5-year silvicultural plan includes soil tillage in 2025; irrigation and replacement of dead plants in 2026–2027; and pruning from 2028 onwards. - Future outlook: The plantation is managed under a 40-year continuous canopy forest plan, with natural regeneration expected after approximately 30 years. A truffle-growing school and guided visits are planned to support knowledge transfer and local engagement.

In the course of 2026, these trees will be planted in the Yunga and Chaco regions of northern Argentina. Our approach rests on two complementary pillars, co-designed with local communities based on what is most needed in each territory. Pillar 1 — Agroforestry restoration We reforest large, now-protected community forests damaged by logging, focusing on native trees of high ecological, cultural and food value — such as carob, mistol and chañar. Following the indigenous logic of native forest enrichment, we restore degraded patches and recover the forest's capacity to feed and sustain the communities who have always lived from it, allowing families to gather fruits and other resources as they have always done traditionally. The planting model prioritises an irregular native forest structure: multiple tree and shrub species of different ages, a complex vertical structure across various strata, and a spatial distribution that emulates the natural patterns of the local ecosystem. Pillar 2 — Intensive agroforestry Since 2025, we have added a second, complementary approach. On defined plots, we develop multi-strata agroforestry systems that replicate forest structures at higher productive intensity, combining native and non-native species — mango, banana, avocado, citrus and moringa — alongside vegetables, legumes, aromatic plants and medicinal species. This pillar directly addresses the malnutrition and health issues caused by forest loss. As neighbouring communities come to learn and establish their own systems, the approach generates a powerful multiplier effect across the region. Once planting has taken place, this section will be updated with the confirmed species, geolocations, pictures and approach (agroforestry restoration or intensive agroforestry)
