Yucatán Reforestation

Since we planted our first tree on March 8, 2015, Our restoration team of now 124 people has planted over 6.3 million trees (as of Jan 2021) on the Yucatán Peninsula. Our goal: 100 million trees by 2030. Thanks to the incredibly dedicated and efficient work of our team, we are able to plant one tree for every euro donated.

Replanting Pastures and Restoring Forests

We are working to restore the forest landscapes in and around the Calakmul Biosphere Reserve. Our work takes place on 20,000 hectares, an area larger than Liechtenstein.

Our sites have suffered different levels of degradation: Some areas are recently abandoned cattle pastures with only a few scattered trees left (like parts of Las Americas 1 & 5).

Other areas were never fully deforested, but most economically valuable trees have been logged (like Las Americas 2 & 6), leaving behind relatively species-poor vegetation. By planting between the remaining vegetation in these areas we are adding back the commonly lost species. In other areas the forest is still full of many species and we are either conserving it or letting it grow back on its own (like Las Americas 3 & 4).

Planting ~20 Native Species

In the past, we mainly planted 8 native species. This year, we will plant at least 20 species to get closer to restoring the original level of tree biodiversity that existed in these forests. Many of the species we are adding back have very dense wood. Such species tend to grow slower but capture a lot of carbon.

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.

In the state of Campeche, where our work takes place, 8.1% of the original forest has been lost since 2002. 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.

Restoration Ecology Research

Since January 2020, we have been operating a 91 hectare research site. Here, scientists from ETH Zürich and Imperial College London conduct large-scale field trials for reforestation with the support of our team. Restoration outcomes are incredibly complicated and variable. Testing theories at this scale allows us to test hypotheses that will help to improve the design and implementation of forest landscape restoration projects. We hope the research will allow us – and other practitioners – to get better at restoring tropical forests.

In an experiment with 16000 trees, we try to understand what percentage of all trees planted should be nitrogen-fixing species to optimise overall survival and growth rates. Nitrogen-fixing tree species can help to fertilize the soil and help nearby tree species, without the ability to fix nitrogen, to grow.

We are also testing a hypothesis that a simple addition of forest-soil to a tree’s planting hole can increase survival rates.

We expect to be introducing symbiotic microbes through the soil addition and thus the soil microorganism diversity in degraded soil towards communities that ‘help’ the trees grow.

In addition to our work on the Yucatán Peninsula, we also work with partners to restore forest in central Mexico. Depending on where they are needed most, tree-donations to Plant-for-the-Planet are allocated to one of these two projects.

You will find an overview of our facts, figures and data since the start of the initiative in 2007 and the establishment of the Plant-for-the-Planet Foundation in 2011, above. In chronological order you can see our program work as we have been supporting children in their commitment to a better climate since 2008, our actions in public relations, the seedlings and trees and also how we have used your donations in the last 13 years.

There are national Plant-for-the-Planet organisations in Mexico, Brazil, the USA, Spain, Italy, the Czech Republic and Switzerland. The national organisations have honorary presidents who, just like Felix Finkbeiner and his parents, work for Plant-for-the-Planet on a voluntary basis, i.e. without pay. In addition to our pilot project on the Yucatán Peninsula in Mexico, we also maintain planting projects in Toluca (State of Mexico), Spain (Ejulve, Sadiz, Doñana, Granada) and Ghana.

After a few decades, tropical forests reach the peak of their carbon storage capacity. After that, the forest absorbs little more additional carbon. Under certain conditions, it can also make conditional sense to selectively remove smaller, weaker trees so that other, larger trees have better growth opportunities and can absorb more CO2. However, these felling operations are not done because of the wood. A forest managed in this way remains close to its maximum carbon storage capacity while financing further afforestation. We do not plan to do so, but we want to keep the option open that in future individual trees could be selectively harvested if this is good for the forest. Of course, this will also be reported on transparently.

The areas on which the trees are to grow also include areas that do not belong to Plant-for-the-Planet. A team of ecologists reviews eligible areas, both state and municipal, and in individual cases, areas owned by small farmers, under the premise that the trees will be cared for and protected, and then recommends individual planting plans. It is up to the owners of those areas to decide. Together with ecologists and also researchers from ETH Zurich, we are currently investigating another 1,000 hectares and making a proposal for optimal reforestation. The owners of those areas then have to decide. So we also plant on municipal land ("ejidal"), and in the future also on state-owned land, under the premise that the trees are cared for and protected.

We have been planting on the Yucatán Peninsula since March 2015, and since 2018 we have been in close collaboration with the Crowther Lab established in 2017 at ETH, Zurich. The Crowther Lab evaluates the field data we collect during the planting process to monitor our recovery efforts and can thus scientifically monitor our activities. Since January 2020, we have also been working with ETH, Zurich and Imperial College, London to implement additional research projects in accordance with the research institutions' study priorities. The scientists' findings also benefit the reforestation strategy in Yucatán.

100% of all contributions (donations) that are earmarked for trees, 1 Euro = 1 tree, go to Planet-for-the-Planet A.C. in Mexico. Of all revenues of the Plant-for-the-Planet Foundation, the following percentages went to the sister organisation Planet-for-the-Planet A.C. in Mexico: 50% in 2015, 61% in 2016, 48% in 2017, 54% in 2018 and 73% in 2019. In addition to earmarked donations for trees, everyone can support the further work of Plant-for-the-Planet and donate unrestrictedly, thus supporting our other programme work. This includes the promotion of children and young people, mobilisation and public relations work, or the further development of the Plant-for-the-Planet App. These revenues make up the difference to the above mentioned 50%, 61%, 48%, 54% and 73%. These earmarked donations are also used to cover administrative costs, which average less than 9%.

In the first few months, it is crucial for the grass surrounding the tree to be kept short, otherwise, they are competing for the sunlight. This is why we always plant our seedlings in rows and at the same distance from each other, so our employees can better identify the seedlings in the grass. Our high survival rate is probably the result of this regular manual cutting of the grass, which is reflected in the consumption of 720 machetes and 7,800 files per year to sharpen them. Presumably, the above-standard payment and the high social benefits for our currently more than 100 employees on the planting area and in the tree nursery also contribute to this and the fact that we do not pay piecework payments or unit premiums, as is often the case with planting, but instead focus on quality and care.

Volcano Valley Reforestation near Toluca

The forests in Mexico, the most populous state in the country, are under increasing threat due to the destruction of large areas of forest through deforestation, forest fires and overgrazing. Poor management of natural resources is worsening the situation. Often the soil quality has already deteriorated to such an extent that natural regeneration of the forests is no longer realistic. Sustainable reforestation is the last option here to prevent further erosion by renewing protective vegetation and increasing soil fertility. As a result, the remaining forests and their resources can be saved for the future. With this goal in mind, Plant-for-the-Planet Mexico A.C. and PROBOSQUE, an organization assigned to the Mexican Ministry of the Environment, agreed to cooperate in the state of México (capital Toluca) in September 2019. The first 2.8 million trees were planted in the same year. The particular feature of this project is that the reforestation covers a total of 197 sub-areas of varying sizes, all of which are managed in small, mostly rural structures. Of these, 92 are jointly managed ejidos (a total of 1,913,775 trees), the remaining areas are divided between small farmers (619,925 trees) and cooperatives (290,300 trees). Within the framework of the planting cooperation with Plant-for-the-Planet, they not only receive support for the reforestation itself but are also advised on how to care for their forests and save them for the future in terms of sustainable forest management, as well as protecting them as an ecosystem on the whole. All restored areas have been declared protected areas. When selecting the newly planted trees, care was taken to ensure that a mixture of indigenous tree species suitable for this part of the country was selected. These include various species of pine, agaves, a mimosa species and the Mexican cypress. They integrate optimally into the still existing forests and by this contribute to the preservation of the local biodiversity of secondary plants and animals. By the end of 2020, we will have planted another 1,500,000 million trees together with the small farmers organized in cooperatives, thus spreading the responsibility of tree care over many shoulders.
