**Located in the heart of the Millevaches Regional Nature Park in Corrèze, the [Peyrelevade](https://www.reforestaction.com/en/projects/2720) project aims to reconstitute a diversified forest while respecting the natural growth and renewal processes of forests. Reforest'Action chose the [Assisted Natural Regeneration (ANR)](https://www.reforestaction.com/en/magazine/anr-expertise-thibaud-poulain) method to enhance 14,700 trees within this natural conservation site, which is part of the Natura 2000 protected areas network. Sasha Pinot, project manager for France at Reforest'Action, provides insight into why this method was chosen, its advantages, and the expected benefits of implementing the project within the framework of climate change adaptation.**

### What does the Peyrelevade project, in the Limousin region, involve?

_Sasha Pinot :_ This natural regeneration project aims to revive a diverse forest ecosystem while meticulously honoring the natural processes of growth and renewal. Today, 14,700 trees of diverse species including Douglas fir, larch, spruce, fir, and oak are being nurtured through meticulous care and effort. Ultimately, this forest in the making will contribute to local economic development, supporting the timber industry. Restoring this degraded ecosystem will help preserve the forest atmosphere and its picturesque landscape. Home to a rich biodiversity, this forest will also contribute to carbon storage and play a role in combating climate change. Located in the heart of the Millevaches Regional Nature Park in Corrèze, Limousin, this natural site holds a special place within the Natura 2000 network, a European initiative dedicated to conserving habitats and species of importance.
 
### What history does this forest have?

_Sasha Pinot :_ Both plots have been planted with Douglas fir, spruce, and Scots pine for the past 35 years. They intended to undergo clear-cutting in the years to come, to harvest the wood produced, and then to be replanted following the same intensive pattern. Clear-cutting involves abruptly opening up an area, resulting in the long-term destruction of many natural habitats essential to certain species. In most cases, it also involves the use of heavy machinery, which destroys soil life by compacting and plowing large areas. 

![Peyrelevade-1.jpg](/uploads/Peyrelevade_1_d8761206cf.jpg)
 
### How is the implementation of an ANR project necessary to restore it?

_Sasha Pinot :_ One of the primary objectives of this project is to halt the forest degradation caused by strict and simplified forest management practices. By embracing a gentler approach, such as Assisted Natural Regeneration, landowners choose not to disrupt the forest's delicate balance. To achieve this, they observe natural processes and only intervene when necessary, in specific areas. Movement within the plots is restricted to designated paths to prevent unnecessary soil compaction. This method not only allows natural cycles to unfold but also enables the silviculturist to reduce their workload, as much of the forest's maintenance is carried out naturally.  
 
### How were the species chosen for the project?

_Sasha Pinot :_ The project promotes a variety of tree species, such as Douglas fir, larch, spruce, fir, and oak, each serving multiple functions. These species are selected from both hardwood and softwood groups and are chosen for their excellent adaptation to the site conditions. Intending to achieve 80% natural regeneration, the project also fosters the growth of other species already present in the soil through their existing seeds.
 
### What's the difference between the ANR method and conventional silviculture?

_Sasha Pinot :_ Today, French forests confront numerous threats, notably those stemming from climate change. In response to these challenges and as a departure from conventional silviculture practices, the proprietors of the Peyrelevade plots have opted to transition towards Assisted Natural Regeneration.

The main distinction between intensive forestry and Assisted Natural Regeneration (ANR) resides in ecological succession. In a natural forest, the process begins with the germination of a select few trees. As the canopy matures and closes, conditions of shade and humidity become conducive to the development of more delicate forest species in the understorey. This understorey strengthens the ecosystem's structure, facilitating the establishment of plants over the long term until they reach maturity. Occasional disturbances, such as storms or natural die-offs, then stimulate the vitality of the ecosystem. A natural forest represents a mosaic of these stages, amalgamating diverse functional groups that mutually support one another.

In contrast, within intensively managed forests, vulnerable trees are typically planted on bare ground, thereby exposing them to various risks such as drought, flooding, and wildlife damage. Often comprised of only one or two species, these forests exhibit a simplistic environmental structure characterized by a singular stratum. Upon reaching maturity, all trees are harvested, necessitating a complete restart of the cycle. Such artificial forests lack resilience to disturbances and significantly curtail the environment's capacity for natural evolution.
However, it is imperative to enhance the resilience of our forests to ensure the continuity of their ecosystem services. Through the decision to honor the natural cycle of their forest and embrace ANR management, the proprietors of this project significantly enhanced their forest's capacity to withstand diverse threats.
 
### How will the forest, restored through Assisted Natural Regeneration (RNA), be more resilient in the face of climate change?

_Sasha Pinot :_ This will be the case on five levels:
- The enhancement of ecosystem stability is notable. Without the disruptive effects of clear-cutting, natural forests maintain a consistent vegetation cover, yielding numerous benefits. Minimal fluctuations in humidity and temperature prevail, as the soil remains shielded from direct sunlight and air currents. The intricate structure of the ecosystem endures, serving as a habitat for a myriad of species, each fulfilling its unique role. The absence of habitat destruction fosters the proliferation of diverse life forms. 
- Trees derive added benefits from supplementary resources. Depending on the species, roots extract water from various depths. The diversity of these root systems enables the exploration of a broad spectrum of water sources, crucial during periods of escalating drought. Moreover, this subterranean complexity contributes to soil structuring, mitigating erosion.  
- The diversity of tree species aids in regulating pests and diseases, which are primary contributors to forest degradation. Predominantly, these issues arise in stands with limited species diversity, as they lack natural predators. In a diversified forest, all species—including animals, plants, fungi, and microorganisms—compete, thus restoring equilibrium between predators and prey.
- Game damage will be minimized. Trees grown from natural seedlings are considerably less appealing to wildlife than those raised in nurseries.  
- In the long term, the forest will yield greater profitability. A diverse array of tree species ensures a harvest, even in the event of disease affecting one species. Additionally, the fertility of the environment is sustained through a dynamic cycle of organic matter, with minimal impact on the soil.

### Why talk about sustainable forest management when it comes to ANR?

_Sasha Pinot :_ By choosing Assisted Natural Regeneration, landowners cultivate high-quality wood while preserving a diverse and thriving biodiversity within the ecosystem. 

Living, productive forests naturally form across the globe, independently of human intervention. Nature provides the necessary seedlings and optimal conditions for their growth, while the diverse flora and fauna maintain a delicate balance against diseases and pests. In the natural cycle, when a tree reaches the end of its life, it falls, creating space for new growth. Young trees from natural regeneration take advantage of these openings, thriving until the canopy is restored. The Assisted Natural Regeneration (RNA) method respects these intrinsic natural principles while favoring the growth of the most beneficial trees.

The species present in the Peyrelevade stand have organically developed. A significant portion of them is local, with genetics finely attuned to the specific conditions of the region. Over time, the stand undergoes natural evolution, favoring only the most competitive and adaptive species.

Numerous instances in the region showcase owners aligning their management practices with natural processes. Situated at the heart of the Millevaches Regional Nature Park, the Peyrelevade project actively contributes to this network, gradually restoring the French forest to its historical state. Its PEFC certification serves as additional confirmation of its commitment to sustainable management, reflecting a comprehensive understanding of the forest's multifunctional role. The PEFC label assures the stringent adherence to precise regulations by all forest stakeholders, including owners, operators, and forestry contractors.

To obtain the PEFC label, various commitments must be upheld, including promoting a diverse array of tree species, abstaining from fertilizer use, safeguarding soil integrity, preserving local fauna and flora, and maintaining dead trees, essential for biodiversity promotion.
 
### How does RNA contribute to sustainable wood production? 

_Sasha Pinot :_ The overarching goal of the Peyrelevade project is to establish a diversified, multifunctional, and resilient forest, while simultaneously benefiting the local economy. 

Unlike conventional silviculture, timber is not harvested from a large area in a single block. The forest's intricate structure calls for more regular, localized harvesting. For instance, rather than harvesting an entire parcel every 80 years, the silviculturist opts to selectively remove only the finest trees every 5 years. Despite the differing approaches, the financial returns remain nearly identical. However, under Assisted Natural Regeneration (ANR) management, the silviculturist benefits from more consistent income.

Implementing this method requires the expertise of skilled tradespeople, and sizable trees must be transported to specialized, smaller sawmills tailored for such operations. These ANR conversion initiatives not only create employment opportunities but also inspire younger generations to acquire and revive traditional knowledge. 

Moreover, Corrèze, being a heavily forested region with ample rainfall and a temperate climate, provides an ideal environment for forest development. Given these favorable conditions, the wood yielded by the Peyrelevade project will be of exceptional quality, thereby benefiting the entire local industry, including forest managers, loggers, and sawmill operators. 
 
### Une gestion forestière en RNA permet-elle de séquestrer autant de carbone qu’une gestion classique ?

_Sasha Pinot :_ The Peyrelevade project stands out notably for its carbon sequestration capabilities. Similar to conventional plantations, the trees continuously sequester carbon throughout their lifespan. This carbon is responsibly stored when the wood is utilized in construction or furniture. Additionally, the ANR method offers an added advantage over traditional silvicultural practices: the preservation of soil carbon. Unlike forests that export their entire production, this type of forest allows for the unimpeded growth of undergrowth and retention of deadwood. As this organic matter decomposes, the carbon it contains remains within the soil, preventing its release into the atmosphere, a common occurrence after clear-cutting and plowing.

It should be noted, however, that while carbon storage is a good indicator for studying climate change, it cannot be used to judge the quality of a forest. For instance, an intensive Douglas-fir monoculture will sequester more carbon on the same surface area than a diversified forest. Yet it is not sustainable, and its ecological value and resilience are much lower.

**As Assisted Natural Regeneration harnesses existing resources to preserve and fortify forest heritage, fostering long-term diversity and resilience, it emerges as particularly pertinent in the face of climate change. However, for ANR initiatives to materialize, funding is essential, notably from companies eager to contribute to forest restoration. Swiss Life Asset Managers exemplifies this commitment by supporting the Peyrelevade project showcased in this article. Across France, Reforest'Action is spearheading ecosystem regeneration endeavors rooted in the Assisted Natural Regeneration method, thanks to funding from dedicated corporate partners.**

"Assisted Natural Regeneration allows forests to be more resilient in the face of climate change": an interview with Sasha Pinot

**Our impact management process has been digitized and we have developed an MRV (Measurement, Reporting & Verification) platform. The aim is to offer investors a tool that provides centralized, selected information on nature-based projects, their monitoring and relative impacts over time. This tool will enable investors to demonstrate the value generated by these nature-based solutions, using key performance indicators and reliable, traceable and verifiable data.**

![MRV_maquette.jpg](https://backoffice.reforestaction.com/uploads/MRV_maquette_83b721a179.jpg)

## A data collection, analysis and reporting tool 

The MRV platform developed by Reforest'Action aims to collect, analyze and report reliable and verifiable data on the implementation, monitoring and impact measurement of our Nature-based Solutions. It enables us to combine all our impact management tools and report the results of project monitoring in the field and by remote sensing, in complete transparency.

The platform also provides impact projections, i.e. modeling and assessment of impacts prior to implementation, enabling us to gain information on projects, adjust their design, implement adaptive management measures and assess their level of performance over the long term.

Our MRV platform relies both on the collection of data from the field (type of species planted, nature of activities carried out in the field, impact on local communities, etc.) and from satellite imagery (forest cover density, actual carbon sequestration by above-ground biomass, number of trees in place, stand health, etc.).

It offers a solution that meets both the needs of project development and the transparency requirements of the companies that finance them:
- In the back office, Project Data Management enables our teams to manage projects, from identification to field monitoring, by centralizing all project-related data (design, audit reports, satellite measurements, etc.).
- In the front office, the dashboard can be used to display project-related key performance indicators (KPIs) for companies committed to monitoring the impact of the solutions they finance.

![Schema-plateforme MRV.png](https://backoffice.reforestaction.com/uploads/Schema_plateforme_MRV_afc2dffaee.png)

## A tool that meets the growing need for transparency and reporting 

Ultimately, Reforest'Action's MRV platform is intended to link all project stakeholders to improve transparency and add value, including in the field. In its first version, available at the end of 2024, it is dedicated to project financiers and provides key performance indicators and impact data, facilitating the monitoring of investments and reporting required by certification frameworks such as the CSRD.

It meets the market's need for transparent, robust and reliable data, addressing the following needs:
- ensuring companies comply with regulatory frameworks (CSRD, Net Zero, etc.)
- supporting companies' reputations and their need to demonstrate the impacts of the NbS they finance
- providing a clear return on investment (ROI) for financed solutions

**Our impact monitoring approach, supported by our digital data reporting tool, enables us not only to work for the health of restored ecosystems, but also to make Nature-based Solutions a reliable impact investment solution.**

Measuring the impact of NbS projects: launch of our MRV platform

**Defined by the IUCN in 2009, the concept of Nature-based Solutions (NBS) is founded on the idea that natural processes, and not just technological ones, can make a significant contribution to tackling major contemporary challenges such as climate change and biodiversity erosion. Nature provides vital services to all living things, and in particular to humankind. It is therefore essential to preserve, restore and manage it sustainably to ensure our future.**

![Nature-Based-Solutions-forest.jpg](https://backoffice.reforestaction.com/uploads/Nature_Based_Solutions_forest_f54ea0ac1f.jpg)

## What are Nature-based Solutions?

Nature-based Solutions are defined by IUCN (International Union for Conservation of Nature) as “actions to protect, sustainably manage and restore natural or modified ecosystems to directly address societal challenges in an effective and adaptive manner, while ensuring human well-being and producing benefits for biodiversity.”

This concept was formulated by IUCN at the Copenhagen Conference in 2009, when forests were proposed as a solution for mitigating climate change. It was at COP21 in 2015 that the place of Nature-based Solutions in climate action was recognized by States, notably via the Paris Agreement.

These are actions that aim to protect, restore and sustainably manage natural ecosystems - be they forests, rivers, wetlands or even bocage meadows - in a logic of mutual benefit, since these ecosystems generate benefits for humanity. Nature-based Solutions also bring benefits for [biodiversity](https://www.reforestaction.com/en/magazine/what-biodiversity-definition-and-issues), by integrating this objective into the very design and implementation of these actions.

![EN_NbS.jpg](https://backoffice.reforestaction.com/uploads/EN_Nb_S_775d13cbc8.jpg)

## How are ecosystems and human societies interconnected?

### A multitude of services to humanity

Ecosystems are multifunctional by nature. The variety of ecosystem functions they produce are not man-made, but the result of slow, patient work shaped by Nature over millions of years. Today, [natural ecosystems](https://www.reforestaction.com/en/magazine/reconnecting-living-sustainable-humanity) make vital contributions to people's lives, such as the production of food, energy and raw materials, as well as a multitude of ecosystem services. For example, forests store carbon, regulate the water cycle, limit local heat peaks, reduce the risk of soil runoff and landslides, and meet vital human needs such as the production of timber and energy, food and medicinal products, and places of well-being and recreation.

### Nature's services to human societies are not unlimited

The worldwide overexploitation of ecosystems leads to their degradation, and thus to their inability to provide resources in the long term. The Global Footprint Network's annual Earth Overshoot Day is a direct illustration of this idea. This date, which marks the day when humanity has consumed all the natural resources the Earth can produce in one year, is obtained by comparing mankind's ecological footprint (which measures the exploitation of the Earth's natural resources) with the planet's biocapacity (its capacity to replenish its reserves and absorb greenhouse gases). Still in surplus in 1961, with a quarter of its reserves unused, the Earth became in deficit in the early 1970s. This day was changed from October 10 in 1999 to August 1 in 2024.

In most regions of the world today, Nature has been significantly altered by multiple human factors, and the vast majority of indicators relating to ecosystems and biodiversity show a rapid decline. For example, the IPBES estimates that today :

- 75% of natural terrestrial environments are degraded;
- 66% of oceans have been altered;
- 85% of wetlands have disappeared;
- 5% of the world's animal and plant species are threatened.

Forests, which are home to 80% of the Earth's biodiversity and support 25% of the world's population, are in constant decline. On a global scale, forest area today represents around 68% of its estimated pre-industrial level. According to the FAO, 240 million hectares of forest were lost to deforestation in tropical zones between 1990 and 2015. In temperate zones, the effects of climate change are affecting forest health: 42% of tree species are now threatened with extinction in Europe, according to the IUCN. Forest animal biodiversity has fallen by [53%](https://www.dw.com/en/worlds-forest-animal-population-sinks-drastically-wwf-report/a-50015580) since 1970.

### Ecosystem degradation also weakens populations

Ecosystems, biodiversity and climate are interdependent. Ecosystems and their biodiversity influence climate, helping to regulate temperature and precipitation. They are essential players in the carbon, water and nitrogen cycles. They help absorb some of the heat and greenhouse gases emitted by human activities. These feedbacks between climate and biodiversity are at the origin of the dynamic balance of the environment in which human societies have developed, and which is today affected by both climate and ecosystem changes. Alterations to ecosystems and the climate-biodiversity pair make human beings more vulnerable, with the loss of food sources, the deterioration of water quality, the [development of new diseases](https://www.reforestaction.com/en/magazine/destruction-ecosystems-favours-rise-new-diseases-and-pandemics) and the exposure of societies to extreme climatic events (droughts, storms, etc.).

Strategies and actions to combat climate change must therefore not only drastically reduce greenhouse gas emissions, but also invest in protecting ecosystems. [Healthy ecosystems](https://www.reforestaction.com/en/magazine/ecosystem-restoration-essential-climate-and-biodiversity) not only help mitigate climate change, but also enable human societies to adapt to its consequences.

## Nature-based solutions for today's societal challenges

### Preserving nature is essential to ensure the future of human societies and businesses

According to the IUCN, the use of NbS would enable us to achieve current societal objectives such as :

- Reducing natural hazards
- Socio-economic development
- Food security
- Water and energy supply
- Health and well-being for all
- Adapting territories to climate change
- Mitigating the effects of climate change on populations (rising sea levels, fires, heatwaves...)

According to the IPBES, these natural solutions will account for 37% of the climate change mitigation measures needed by 2030 to achieve the goal of global warming below 2°C by 2100. But implementing NbS on the scale required to meet these societal challenges requires the involvement of all stakeholders, including private sector companies.

### Forests: a key component of Nature-based Solutions

NbS value the services provided by ecosystems that have been preserved, restored or sustainably managed, and are based on various underlying concepts listed by the IUCN. Among these Nature-based Solutions is the restoration of forest landscapes. This process aims to mobilize and involve local communities in restoring the multifunctionality of forests, in order to sustainably meet human needs. This type of project can be implemented through a variety of actions involving the preservation, restoration and sustainable management of forests. All these actions enhance forest biodiversity, and increase carbon capture, which helps mitigate the risks of climate change:
- Preservation of existing forests in good ecological condition
- Restoration of degraded forests or creation of forest ecosystems
- Adoption of sustainable forest management practices
- Creation of protected areas (national or regional parks, nature reserves, etc.) to protect associated territories and preserve ecosystem services
- Reforestation and ecological restoration of degraded forest habitats using adapted and diverse species, giving priority to indigenous species;
- Creation of hedgerows and [agroforestry systems](https://www.reforestaction.com/en/magazine/agroforestry) to regulate climate and the water cycle, conserve soil and create biological corridors for flora and fauna;
- Exclusion of unsustainable practices such as monospecific plantations, clear-cutting that weakens soils and overexploitation of stands;
- Development of [Assisted Natural Regeneration](https://www.reforestaction.com/en/magazine/assisted-natural-regeneration-complementary-solution-tree-planting-restore-degraded-forests);
- Creation of islands of senescence, made up of ageing trees which, as they decompose, promote the fertility of forest soils, the main reservoir of biodiversity in the forest;
- Promoting wood products from sustainably managed forests.

Le projet s'inscrit dans le Domaine de Grangemenant Beautheil, au Sud-Est de Paris. Des peuplements clairsemés, principalement constitués de chênes sessiles (gros bois et semis) occupent aujourd'hui les quatre parcelles concernées par ce projet. Ils sont accompagnés par des semis chêne pédonculé, charme, tremble. La surface couverte par la régénération atteint 75% de la surface du projet. Les semis, issus des semenciers, permettront d’entamer un nouveau cycle sylvicole. Cette continuité sera adaptée aux conditions climatiques et biotiques. Par ailleurs, le projet vise à accompagner la régénération naturelle du massif par l'implantation de nouvelles essences de fruitiers forestiers. Ces dernières permettront de diversifier la régénération déjà en place, et d'enrichir les trouées. Ce projet propose diverses opérations qui permettront d'accompagner les semis afin de garantir un renouvellement de la forêt. Le projet permettra donc d'améliorer la multifonctionnalité de la forêt.

Preservation of local biodiversity by providing suitable habitats and resources.

Contributes to the mitigation of the greenhouse effect and influences precipitation patterns and the local microclimate.

Influences the quality and integrity of the soil-water system, and the cycling of water and nutrients.

Supports human well-being, by providing resources, income, education, and supporting recreation and heritage.

The project is part of the Grangemenant Beautheil estate, south-east of Paris. The four plots involved in this project are currently occupied by sparse stands of sessile oak (large trees and seedlings). They are accompanied by seedlings of pedunculate oak, hornbeam and aspen. The area covered by regeneration represents 75% of the project area. The seedlings, grown by the seed companies, will be used to start a new silvicultural cycle. This continuity will be adapted to climatic and biotic conditions. In addition, the project aims to support the natural regeneration of the massif by planting new forest fruit species. These will help to diversify the existing regeneration and enrich the gaps. The project proposes a range of operations to accompany the seedlings and ensure forest renewal. The project will thus enhance the forest's multifunctionality.

Situé au cœur du Parc Naturel du Gatinais, ce vaste massif forestier est composé de feuillus, notamment de chênes en taillie ou taillie sous futaie. Malheureusement, les peuplements présents sur les 3 parcelles concernées sont relativement pauvres en raison d’une gestion inappropriée, de la présence d’une population excédentaire de gibier et d’une gestion forestière dépassée (basée sur des rotations de coupes à blanc par blocs). L’objectif aujourd’hui est de modifier le mode de gestion du massif et de rétablir l’équilibre et la diversité du peuplement. Le projet prévoit donc de conserver les semenciers présents, de conduire des dépressages et dégagements des semis et d’enrichir le peuplement d’essences diverses indigènes pour accélerer la régénération des peuplements. Cette démarche permettra d’enrichir les services écosystémiques du massif mais également d’augmenter sa capacité de production de bois.

Located in the heart of the Gatinais Nature Park, this vast forest is made up of deciduous trees, in particular coppiced oak. Unfortunately, the stands on the 3 parcels concerned are relatively poor due to inappropriate management, the presence of an excess game population and outdated forest management (based on block clear-cutting rotations). The aim today is to change the way the massif is managed and restore the balance and diversity of the stand. The project therefore involves conserving existing seed trees, carrying out depressurization and seedling removal, and enriching the stand with a variety of native species to accelerate regeneration. This approach will not only enrich the ecosystem services of the massif, but also increase its wood production capacity.

En effet, la diversité d'essences permet d’améliorer l’accueil de la biodiversité. Enfin, cette typologie de plantation permet également de créer des continuités arborées entre des petites parcelles forestières alentours. Cette continuité est favorisée par ces implantations de haies qui permettent de créer des corridors écologiques.  L'impact paysager n'est donc pas négligeable, d'autant plus que cette haie protégera les parcelles agricoles des aléas climatiques (vents, pluie, soleil).

On the Montjean plain in the Val de Marne, the introduction of a mixed bocage hedge into this non-wooded agricultural landscape was initiated by the farmer who owns the plot. Tomorrow, 26 species of mixed deciduous trees will make up this Val-de-Marne hedge. This hedgerow planting project will create a completely different agricultural landscape, while improving the environment for local flora and fauna. Bocage hedges also improve the life of agricultural soils. In fact, the diversity of species helps to improve the reception of biodiversity. Last but not least, this type of planting also creates tree continuities between small forest plots in the surrounding area. This continuity is encouraged by the hedges, which create ecological corridors. The landscape impact is therefore not negligible, especially as this hedge will protect the agricultural plots from climatic hazards (wind, rain, sun).

Peuplier

Érable sycomore

Non loin d'Épernay dans la Marne, ces parcelles situées sur les communes de Saint-Martin-d'Ablois et Boursault, totalisant 49 hectares, ont été mises en régénération cette année. La Régénération Naturelle Assistée est une méthode qui consiste à accompagner de jeunes plants jusqu'à l'âge adulte. Cet accompagnement se matérialise par des travaux sylvicoles qui permettent de valoriser les arbres afin d'obtenir un peuplement pérenne. Dans ce peuplement, les arbres promus et valorisés sont majoritairement des chênes (sessiles et pédonculés) ainsi que diverses essences d'accompagnement telles que le châtaignier, l'aulne glutineux, le charme, le tremble et le bouleau. Ce projet propose diverses opérations qui permettront d'accompagner les arbres en place. Il permettra aussi la sauvegarde d'arbres à valeur environnemental forte et d'accompagner les futures pousses. Le projet permet donc d'améliorer la multifonctionnalité de la forêt (biodiversité, économique et carbone).

Not far from Épernay in the Marne department, these 49-hectare plots of land in the communes of Saint-Martin-d'Ablois and Boursault have been regenerated this year. Assisted Natural Regeneration is a method that involves supporting young plants until they reach adulthood. This support takes the form of silvicultural work to enhance the value of the trees and create a perennial stand. In this stand, the trees promoted and developed are mainly oaks (sessile and pedunculate), along with various companion species such as chestnut, black alder, hornbeam, aspen and birch. This project proposes a range of operations to accompany the existing trees. It will also safeguard trees with high environmental value and support future growth. The project will therefore enhance the forest's multifunctionality (biodiversity, economic and carbon).

Poirier sauvage

Dans le département de Seine-et-Marne en Ile-de-France, les arbres de cette ancienne parcelle forestière ont été ravagés par la tempête Lothar de 1999. Le projet vise à redynamiser le peuplement grâce à l’introduction de 4 essences feuillues permettant de rétablir un couvert forestier de qualité. Aujourd’hui, l’introduction de 20 000 arbres permet de redonner vie à un écosystème plus résiliente face aux changements climatiques. Le massif, enrichi d’une nouvelle diversité, accueillera une faune et une flore locale et contribuera à harmoniser le couvert forestier de la zone. Les arbres captureront le carbone et contribueront à la lutte contre le dérèglement climatique. Finalement, ils assureront également une continuité forestière sur la zone et participeront pleinement à la formation d’un patrimoine forestier résilient.

In the Seine-et-Marne department in the Ile-de-France region, the trees in this former forest plot were devastated by the Lothar storm of 1999. The aim of the project was to revitalize the stand by introducing 4 deciduous species, thereby re-establishing a high-quality forest cover. Today, the introduction of 22,200 trees has given new life to an ecosystem that is more resilient to climate changes. Enriched with new diversity, the massif will host local flora and fauna and help harmonize the area's forest cover. The trees will capture carbon and help combat climate change. Finally, they will also ensure forest continuity in the area and play a full part in creating a resilient forest heritage.

Ce projet mené en lien avec l’association Haie Magique, est situé en Moselle. Il regroupe 12 projets de plantation visant l’implantation de haies bocagères, aux nombreux avantages tant environnementaux que sociaux. Aujourd’hui, 4 321 arbres d’essences diverses sont désormais plantés autour des parcelles concernées. Cette diversité favorisera l’enrichissement de la biodiversité locale, en créant des corridors écologiques liés les uns aux autres. De plus, cette plantation située en milieu urbain sensibilisera les riverains sur les enjeux liés à la forêt et à la sauvegarde de la biodiversité, tout en améliorant leur qualité de vie. En parallèle, les arbres plantés stockeront du carbone, participant ainsi à la lutte contre le changement climatique. De plus, les arbres assureront une continuité arborée dans la zone.

SUSTAINABLE_CITIES_AND_COMMUNITIES

This project brings together 12 projects carried out in urban areas by the Haie Magique association. These plantings, which are often participatory, raise awareness among local residents while improving the green fabric of the countryside. These projects will create islands and hedges that will host local biodiversity and help to improve ecological continuity in these cities, which are largely devoid of vegetation. These plantings will also improve soil quality, both in terms of structure and composition. Soil that has been decompacted by vegetation will allow water to infiltrate better, thus avoiding extremely compacted urban soils. Finally, these projects often include a few edible species, enabling local residents to learn about and enjoy these plants.

This project, run in conjunction with the "Haie Magique" association, is located in Moselle. It brings together 12 planting projects aimed at creating hedgerows with numerous environmental and social benefits. To date, 4,321 trees of various species have been planted around the plots concerned. This diversity will enhance local biodiversity by creating interlinked ecological corridors. What's more, this planting in an urban environment will raise local residents' awareness of forestry and biodiversity issues, while improving their quality of life. At the same time, the trees planted will store carbon, helping to fight climate change. What's more, the trees will ensure continuity throughout the area.
