Best reforestation projects in Spain

This Sustainable Forests project is a restoration initiative in a highly valuable protected natural area, the Montseny Natural Park. It seeks to restore an old quarry, contributing to the promotion of biodiversity and the sustenance of essential ecosystem services in the area.

This foundation works on the restoration of damaged ecosystems, sustainable forest management, and climate leadership training, using a collaborative model. Its vision that environmental restoration must be accompanied by social and economic benefits makes it a key player for a sustainable future.

This project is the largest reforestation and emissions reduction initiative in Spain, with a triple positive impact approach. Its goal is to reforest 70,000 hectares to offset 16 million tons of CO2 emissions, generating local employment and significant environmental impact.

This company is a pioneer in the use of new technologies such as big data, smart seeds, and drones to reforest large areas efficiently. Its innovative approach allows repopulating hard-to-reach areas and those devastated by fires up to 100 times faster than traditional methods.

It has consolidated its position as a leader in carbon credits in Spain, transforming traditional reforestation into an integral model with environmental and social impact. It manages 3,000 hectares of forestry projects, combining CO2 absorption, ecosystem restoration, and long-term forest management.

This large-scale project, initiated in 2009, has recovered over 1,000 forest hectares in 21 enclaves across 13 autonomous communities. It has planted over 850,000 trees and shrubs, with an investment of 3 million euros, and is expected to fix 260,000 tons of CO2.

Retree uses algorithms and manual labor to regenerate grasslands and reforest, having regenerated 123.48 hectares in various regions of Spain and Portugal. Its 'smart reforestation' approach allows optimizing efforts and protecting nature against climate change and desertification.

This non-profit NGO is dedicated to conservation and reforestation, with active projects in various autonomous communities. Its commitment to reversing environmental degradation and the participation of volunteers make it a relevant entity in the reforestation landscape in Spain.

Launched in March 2026, these projects by the Junta de Andalucía are very current and reinforce the role of forest ecosystems as natural carbon sinks. They aim to capture over 3,500 tons of CO2 in less than 80 hectares through strategic reforestation and ecological restoration.

This project stands out for the use of innovative technologies such as big data, smart seeds, and drones for more efficient and rapid reforestation over large areas. Plantings are scheduled for next autumn, recovering areas devastated by fires and plots without trees.

This ambitious project aims to plant more than 6,000 trees and 16,000 native shrubs along 8 km at the mouth of the Guadalquivir. It promotes landscape recovery and allows fauna to develop with greater independence from the anthropized environment, being an active and relevant project.

This Plant-for-the-Planet initiative is crucial for recovering the ecosystem and biodiversity in approximately 9,000 hectares of the Las Peñuelas pine forest, affected by the 2017 fire. It addresses an urgent reforestation need in a natural area of high ecological value.

This program is a benchmark in regional forest management, with a significant impact on expanding forest resources and improving their quality. It has afforested over 200,000 hectares, investing over 500 million euros and absorbing more than 29 million tons of CO2 by 2022.

This initiative, supported by Abanca since 2020, has allowed the planting of over 650,000 trees and the restoration of a considerable area in the four Galician provinces. It promotes the planting of native species in forest areas degraded by fires or catastrophes, with the aim of offsetting CO2 emissions.

This Reforesta project, with plantings in 2021-2022 and emergency irrigation in March 2026, addresses the problem of low species diversity and fire risk. It planted 1,216 trees and shrubs with color codes to increase biodiversity and fire resistance in a previously affected area.

Announced in January 2024, this initiative by the Ministry of Environment is recent and large-scale, combining repopulation with environmental awareness. More than 12,000 trees of 50 native species will be planted in 77 reforestation and environmental education activities, involving children and young people.

These reforestation days, scheduled for March 2026, are very current initiatives that seek to strengthen environmental awareness and promote concrete actions to protect the natural environment in the region. They combine the participation of companies and citizens for environmental recovery, within the framework of the Year of the Environment 2026.

This Sustainable Forests project is a long-term restoration initiative in an area of great conservation value within the Sierra de Gredos Regional Park. Active after the 2009 fire, it seeks to restore the forest mass in Public Utility Mountain No. 134 of Orzaduero, curb erosion, and promote biodiversity.

This Sustainable Forests project contributes to CO2 emissions offsetting and the promotion of sustainable forest management on private properties. It focuses on creating a forest carbon sink on private land in Dos Aguas, Valencia, demonstrating the feasibility of reforestation on this type of property.

This Plant-for-the-Planet initiative, in collaboration with the City Council, addresses the problem of 'seca' (cork oak decline) and promotes the recovery of emblematic species of the Mediterranean forest. It seeks to plant and restore cork oaks, recovering biodiversity and the landscape in Alcalá de los Gazules, Cádiz.
