Why
The forests of the Yucatán Peninsula are being rapidly destroyed. Since 2015, we are working to restore and protect them. We do so by supporting the government in protecting its reserves, by restoring forests in and around the reserves on larger degraded areas and by supporting farmers in planting trees on their property.
8.1% of Campeche’s forest has been lost between 2002 and 2023. We need to fight back.
How
How we restore forests
the seven steps from devastation to biodiversity
1
Analyse Sites
Our botanical team analyses the soil conditions, precipitation and species in the degraded areas and nearby sites to understand what needs to be planted to restore the lost forests.
2
Collect Seeds
The seeds for many of the rarer species are gathered in nearby ecosystems by external collectors.
3
Grow Seedlings
Our Research Nursery in Constitución, Campeche focuses on growing the rare species that are essential for restoring the ecosystem. Additionally, we work closely with a partner nursery in Chuina, Campeche to grow the rest of our seedlings.
4
Prepare Sites
Before planting can begin, we remove grasses around the planting holes. To seed up the process, this is usually done by cutting lines with machetes.
5
Plant Seedlings
The most likely moment for a seedling to die is in the process of being out planted. To increase their chance of survival, we only plant in the rainy season when there is sufficient water for the seedlings to establish themselves.
6
Protect Seedlings
Rapidly growing grasses endanger the seedlings in the early years by competing with them for water and sunlight. Depending on the size of the seedlings and the grass growth rate, we cut the grass around the seedlings to give them a better chance of surviving.
7
Monitor
Monitoring the planted seedlings and the ecosystem more generally is essential to learn from mistakes and to measure to impact of our work. The most important component is a set of distributed monitoring plots. A team of three collects data all year.
Two Approaches
Agroforestry & Landscape Restoration
Most of our tree planting efforts focus on restoring larger swaths of degraded forest areas inside
and near natural protected areas. However, in collaboration with the environment ministry of the government of Campeche, we also work with local farmers to support them in restoring their farmland by planting trees.Balam Beh
Protecting Jaguars by Connecting Forests
The forests of the Yucatan peninsula is home to the largest jaguar population outside Brazil. But the fragmentation of the forests endangers the population. With our partners, we are working towards connecting the jaguar subpopulations.
Restoration Ecology Research Station
Our restoration work allows our in-house academic research team and visiting scholars to conduct large-scale field trials to test restoration methods.Learn More

Semi-evergreen Tropical Forest
We aim to restore a seasonal semi-evergreen tropical forest. Unlike the wetter forests we imagine when we think of the tropics, these forests have 4–6 month long dry seasons where only little rain falls. Where we work, 25–50% of the trees drop their leaves during that time because they are water stressed.
A Biodiversity Hotspot
Restoring this ecosystem is not just important for plants, but also the animals. In Campeche, jaguars and tapirs are in danger of extinction because of deforestation, habitat fragmentation and incidental deaths by human encounters.
In our sites, we often wake up to the sound of howler monkeys near the camp and see box turtles while planting. So far, only Nicolas, Juan and Jose have seen Jaguars.
41 Tree Species
We want to restore these forests to capture carbon and to protect the local biodiversity of plant, animal, fungal and other species. We are continually increasing the number of species we plant. This includes many early successional species for our restoration in formerly pasture sites and dense wood species in our enrichment planting work.

Project Data
Trees Planted
In 2024, we planted 1,745,514 trees between the 18th of July and the 5th of December.
Watch our Progress
Planting sites are registered daily with TreeMapper, a free forest monitoring app we built.
What Affects Survival?
Survival rates vary widely and depend on species planted, soil type, soil quality, ecosystem degradation, and rainfall and other factors. We prioritize biodiversity over maximizing survival and increase planting density in degraded areas to support
long-term forest development.Measured Survival Rates
One-year survival rates by planting year for Las Americas & INIFAP Bacalar sites2021: 0.1% – 79%
2022: 30% (0%*) – 64%
2023: 10% (0%*) – 73%
*Monitoring plots affected by fires resulted in 0% survival; lower-bound values exclude fire-affected areas.
Survival Rates
We monitor tree survival through a series of monitoring plots plotsince 2021. Our research effort look at how different restoration methods may increase survival rates and growth rates.
Restoration Incidents
Managing environmental incidents, like flooding and fires are an important part of our work. In the interest of transparency, we are logging all such incidents.Restoration Incidents

Behind the Scenes
Our team of ecologists plans and manages our ecosystem restoration and conservation from our office in the village of Constitución, Campeche. It is the closest village to our project sites and home to many of our team members.

Program Partners
Our work is possible thanks to the close colloboration of the government and local research institututions.
