### 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

**Between 2017 and 2022, Yagasu and Reforest'Action worked together to restore 415 hectares of mangrove in the north of the Indonesian island of Sumatra by planting more than a million mangrove trees of six different species. In November 2023, an audit carried out by Reforest'Action highlighted the excellent recovery of the mangroves and the wide range of socio-economic benefits generated by the project for local communities.**

![IMG_20231121_141657.jpg](/uploads/IMG_20231121_141657_3b10a7f915.jpg)

## Five years working to restore the mangrove

Initiated in 2017 in the provinces of North Sumatra and Aceh, Indonesia, the project was spread over four planting seasons for a total of five years, during which 260 plots of degraded mangrove were restored over a total area of 415.6 hectares. Consisting mainly of deforested riverbanks, coastal areas and abandoned fishponds, these plots were selected by our local partner Yagasu near 29 villages on the west coast of Sumatra.

![IMG20231120164535.jpg](/uploads/IMG_20231120164535_6bbbbaa638.jpg)

The aim is to regenerate mangrove forests where they have been deforested or severely degraded by the conversion of land to oil palm monoculture, and to help convert former intensive aquaculture ponds into natural mangrove areas or silvofishery ponds with moderated fishing activities. The planting of mangroves enables the original ecosystem to be reconstituted, along with its services such as fixing unstable soils and combating erosion and rising water levels. Because the existence of mangroves improves water quality and helps increase fish production, planting around or inside the ponds serves the dual purpose of maintaining the structural integrity of the ecosystem and providing a sustainable source of food for aquatic life.

![IMG20231122113205.jpg](/uploads/IMG_20231122113205_aafc5347bf.jpg)

## The conclusions of the audit carried out by Reforest'Action

A total of 1,040,478 mangrove trees were planted in the field after being produced in nurseries designed for the project. The diversity of species, which is essential to the quality and sustainability of mangrove restoration operations, was particularly observed through the selection of 6 different mangrove species adapted to the environment: Rhizophora spp, R. Apiculata, R. Stylosa, R. Mucronata, Avicennia and Ceriops. 
Thanks to the meticulous measurements carried out during the audit mission conducted by Reforest'Action in November 2023, the overall average survival rate of the trees for all the different seasons of the project was determined to be 89.88%. The plots are now in vigorous health and growth, and free of any plant disease.

## A wide range of socio-economic benefits generated by mangroves

### Raising community awareness of the valuable resources provided by mangroves

Over the five years the project has been running, it has directly benefited 4,552 people and indirectly 9,104 people. The mangrove restoration campaign led by our project implementer Yagasu has not only generated employment in the nurseries and planting operations but has also created income-generating socio-economic activities for local people. These include the creation of traditional batik fabrics using mangrove ink, the production of foodstuffs (crisps, crackers) from mangroves, and the practice of silvofishery, which exploits the natural fish resources (fish, prawns, crabs) of these forests by creating natural ponds within them.

![IMG-28763939 (5).jpg](/uploads/IMG_28763939_5_6eb90e170c.jpg)

By becoming aware of the benefits provided by mangroves, local communities are more inclined to adopt a conservation approach to these precious forests, and to contribute to their protection, in particular by setting up community patrols to survey the mangroves and report any deforestation activity.

### Creating local commercial channels

In terms of market opportunities for the production of batik and food products, Yagasu is working with communities to create genuine local commercial channels and raise awareness among consumers from local populations and visiting tourists. As far as silvofishery is concerned, Yagasu facilitates transactions between producers and end consumers through local intermediaries. 

Women's communities in particular benefit from these socio-economic programmes, which contribute to the development of their skills and their financial independence. In fact, the income generated by the socio-economic activities within the women's groups is equivalent to an increase of around 15 to 20% on their pre-project income.

![DSC01584.JPG](/uploads/DSC_01584_aea4f5f18e.JPG)

### Developing ecotourism to boost the local economy

In addition, the project is also enabling the development of ecotourism infrastructures and educational activities, such as nautical tourism, culinary tourism and tourism based on awareness of mangrove ecosystems. In Pasar Rawa, in particular, the ecotourism programme is generating employment for villagers and contributing to the local economy, while promoting a better understanding of the importance of mangrove conservation.

![DJI_0576.jpg](/uploads/DJI_0576_dc277a52c5.jpg)

**The project run by Reforest'Action and Yagasu in Sumatra between 2017 and 2022 has thus contributed not only to the restoration and conservation of mangrove ecosystems located in two provinces of the Indonesian island, but also to the creation of profound socio-economic impacts among local communities by promoting sustainable livelihoods and their economic resilience.**

Sumatra: economic resilience depends on environmental restoration

**At Reforest'Action, the diversity of our solutions meets the diversity of the needs of forests, with common objectives: to make forests more resilient, to develop their multifunctionality, and to preserve and develop the carbon and biodiversity sinks of tomorrow. In this way, Assisted Natural Regeneration (ANR) plays an essential role in achieving global objectives relating to climate, biodiversity and ecosystem restoration, and is fully in line with our environmental and ecological ambitions and those of the foresters with whom we work. Reforest'Action frequently uses this method as part of its ecosystem regeneration projects in temperate zones.**

## Respecting and imitating the natural cycle of the forest
In practical terms, ANR is a method of regenerating forest ecosystems that involves intervening in existing forests that are showing signs of regeneration, but which are insufficient on their own to guarantee the renewal of the forest and the maintenance of its ecosystem services. This is a gentle method of silvicultural management that respects the natural cycle of the forest, the soil and existing biodiversity. It makes the most of what already exists to preserve and strengthen the forest heritage, making it more diverse and resilient in the long term. 

As part of an ANR project, the forester helps the forest to regenerate under optimum conditions. The aim is to encourage the growth of seedlings and juvenile trees of different species that are already naturally present in the soil, and to provide them with the light and space they need to develop in the best possible way. While taking care to maintain minority species to preserve the diversity of the forest, work is also carried out to promote the species best adapted to local conditions and climate change. To do this, the forester will carefully observe the evolution of the forest and, over time, carry out various types of forestry work (clearing, scrub clearance, pruning, maintenance of access roads and enrichment of islands, etc.) that will enable the most promising seedlings to grow thanks to the increased space and light. 

## A complementary solution to reforestation
In our projects, the choice between the planting method or the ANR method depends on the type of forest plot and the history of the forest to be restored. In France, and more generally in Europe, the challenge is to deal with the biotic and abiotic degradation of forests, rather than deforestation, which involves leaving plots of land bare. Given the increasing frequency and severity of natural and climatic hazards, where the situation permits, ANR appears to be the most appropriate method for restoring degraded forests. The funding of ANR work also makes it possible to encourage longer silvicultural cycles and more progressive, sustainable management. It is therefore common for Reforest'Action to support ANR projects in temperate zones.

## Preserving and developing carbon and biodiversity sinks
This method also focuses on preserving biodiversity and the carbon storage function of soils and above- and below-ground biomass throughout the process, by avoiding clear-cutting and bare soil. Thanks to artificial intelligence models and cutting-edge technologies based in particular on satellite imagery, Reforest'Action is now able to estimate above-ground and underground biomass at a given moment and deduce the carbon stored on our ANR projects. With a view to projecting and measuring impact, our ANR projects are designed as genuine projects to preserve carbon sinks and biodiversity.

Pin maritime

Pin sylvestre

Situé sur le domaine de Chantilly, accueillant près de 400 000 visiteurs chaque année. La forêt s’étend sur plus de 6000 hectares. Malheureusement, depuis 30 ans, le massif dépérit. En cause, les vagues successives de sécheresse. La majorité des chênes est en effet victime de la hausse des températures. De plus, depuis quelques années, des larves de hanneton ont fait leur apparition, causant d’importants dommages. Quant aux jeunes semis, ils peinent à se régénérer sous la pression du gibier, ce qui met en danger l’avenir de la forêt.  Afin de restaurer le massif, des essences diversifiées, adaptées aux conditions climatiques de la région, sont plantées pour redonner vie à un massif pérenne et résilient. En parallèle, des travaux de silviculture sur les jeunes arbres sont menés pour accompagner la régénération du peuplement. À terme, la forêt de Chantilly retrouvera toute sa vigueur et pourra continuer à remplir ses fonctions environnementales, paysagères, sociales et économiques. 

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

Preservation of local biodiversity by providing suitable habitats and resources.

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 located on the Chantilly estate, which welcomes almost 400,000 visitors every year and whose forest covers more than 6,000 hectares. Unfortunately, over the past 30 years, the forest has been declining. The cause is successive waves of drought that threatens the majority of oak trees. Moreover, in recent years, cockchafer larvae have made an appearance, causing considerable damage. As for the young seedlings, they are struggling to regenerate under the pressure of game, which is jeopardizing the future of the forest. In order to restore the forest, a wide range of tree species adapted to the region's climatic conditions are being planted to give new life to a sustainable, resilient forest. At the same time, silvicultural work is being carried out on young trees to support the regeneration of the stand. Eventually, the Chantilly forest will regain its full vigor and be able to continue fulfilling its environmental, landscape, social and economic functions.

Située au Nord-Est de la ville de La-Roche-sur-Yon, cette ancienne terre agricole a été abandonnée il y a quelques années. Deux essences feuillues, le chêne et le charme, ont été choisies pour être plantées sur cette parcelle car elles sont adaptées à la station et résistantes aux aléas climatiques et biologiques locaux. De plus, divers arbres fruitiers forestiers seront implantés et permettront la diversification du peuplement. La croissance de cette nouvelle forêt durablement gérée permettra de capter du dioxyde de carbone atmosphérique, luttant ainsi contre le réchauffement climatique. La diversité des essences permettra un meilleur accueil de la biodiversité tout en fournissant des matériaux et une source d'énergie durable. De plus, les arbres assureront une continuité forestière et la formation d’un patrimoine forestier sur la zone.

Located northeast of the town of La-Roche-sur-Yon, this former farmland was abandoned a few years ago. Two deciduous species, oak and hornbeam, have been chosen for planting on this plot, as they are adapted to the site and resistant to local climatic and biological hazards. In addition, a variety of forest fruit trees will be planted to diversify the stand. The growth of this new sustainably-managed forest will help capture atmospheric carbon dioxide, thereby fighting global warming. The diversity of tree species will provide a better habitat for biodiversity, while supplying materials and a sustainable source of energy. In addition, the trees will ensure forest continuity and the formation of a forest heritage in the area.

Dans les Pays de la Loire, la parcelle vendéenne peuplée essentiellement de saules et de quelques chênes fait l’objet d’un reboisement. Afin de dynamiser cet espace qui ne présente plus de signe de régénération naturelle, la parcelle accueille 9000 arbres issus 10 essences à dominante feuillue. Cette démarche rendra la forêt plus résistante face aux aléas extérieurs, tout en favorisant le développement d’une biodiversité riche et variée. Par ailleurs, la reconstitution de cet écosystème permettra de stocker du carbone, participant ainsi à la lutte contre le changement climatique. Une fois matures, les arbres contribueront aussi à la production durable de bois d’œuvre. Ils assureront également une continuité forestière sur la zone et participeront pleinement à la formation d’un patrimoine forestier résilient

In the Pays de la Loire, a plot of land in the Vendée region, populated mainly by willows and a few oaks, is being reforested. To revitalize this area, which no longer shows any signs of natural regeneration, the plot is planting 9,000 trees of 10 predominantly deciduous species. This approach will make the forest more resistant to external hazards, while encouraging the development of a rich and varied biodiversity. In addition, the reconstitution of this ecosystem will enable carbon to be stored, thereby helping to combat climate change. Once mature, the trees will also contribute to sustainable timber production. They will also ensure forest continuity in the area, playing a full part in the creation of a resilient forest heritage.

Situé en Vendée, dans les Pays de la Loire, ce projet a pour objectif de boiser une parcelle agricole située sur le pourtour d'une habitation. Le propriétaire souhaite constituer un patrimoine arboré en introduisant un panel de 17 essences feuillues diversifiées. Ces différentes essences sont adaptées au sol et aux conditions de la station, rendant ainsi la forêt plus résistante face aux aléas extérieurs. À terme, cette forêt constituera un lieu d'accueil pour la biodiversité environnante et permettra d'améliorer la structure et la fertilité des sols agricoles de la zone. Par ailleurs, les arbres plantés stockeront du carbone, participant ainsi à la lutte contre le changement climatique. Enfin, les arbres plantés assureront également une continuité forestière et participeront pleinement à la formation d’un patrimoine forestier.

Located in Vendée, in the Pays de la Loire, this project aims at reforesting an agricultural plot located on the periphery of a house. The landowner wishes to constitute a wooded heritage by introducing a mix of 17 diversified deciduous species. These different species are suited for the soil and the conditions of the stand, and make the forest more resistant to natural hazards. Eventually, this forest will constitute a welcoming place for biodiversity and will increase the structure and fertility of the agricultural soils in the area. Besides, the trees planted will store carbon, which will help fight climate change. Finally, the trees planted will ensure forest continuity in the area and fully participate in creating a forest heritage.

Situé en Seine et Marne, sur la commune de Chartrettes, le projet vise à dynamiser un peuplement forestier ayant souffert d'un manque de gestion et d'exploitation durant une longue période. Pour se faire, le propriétaire souhaite travailler avec l'existant, à savoir la régénération naturelle, déjà installée. Le peuplement actuel se compose de chênes, chataigniers, alisiers torminale, érable sycomore, bouleau, tremble, tilleul et charmes. Cette grande hétérogénéité d'essence sera conservée au profit de la biodiversité. De même, des arbres de biodiversité et du bois mort au sol seront maintenus.

Seine et Marne is the leading agricultural department in the Ile-de-France region, with almost 60% of its land dedicated to various crops. Likewise, the Ile-de-France region has an afforestation rate of 23%, well below the national average of 31%. The project therefore makes perfect sense in a context dominated by agriculture and urbanization. It will serve as a refuge for numerous plant and animal species.

Located in Seine et Marne, in the city of Chartrettes, the project aims at galvanizing a forest stand which suffered from a lack of management and of cultivation for a long period of time. To do so, the landowner wishes to work with what's already there, which is the regeneration already at work. The current population is made up of oaks, chestnut trees, checker trees, sycamore maples, birches, aspens, lime trees and hornbeams. This great heterogeneity of varieties will be preserved to benefit the biodiversity. Biodiversity trees and dead wood on the ground will also be preserved. In the long term, the project will support a rich biodiversity, resistant to biotic and abiotic hazards.

Dans le Grand Est, cette parcelle de la Meuse a été fragilisée par le réchauffement climatique et par des ravageurs. Le peuplement, affaibli par des étés chauds et secs, a subi une attaque destructrice de scolytes. Ces insectes creusent un réseau de galeries sous l'écorce des arbres pour s'y nourrir et se reproduire. Afin de restaurer l’écosystème forestier de cette parcelle, un projet de régénération naturelle est initié. Ce mode de gestion douce permet de valoriser la forêt existante pour lui permettre de s’adapter au changement climatique. Le peuplement sera enrichi d’essences développées localement. Aujourd’hui, 27 000 arbres font ainsi l’objet de travaux sylvicoles, en partenariat avec la commune de Ligny en Barrois. À terme, le peuplement régénéré sera plus résistant aux attaques d’insectes et au aléas climatiques.  Les arbres pourront accueillir une biodiversité et contribueront à lutter contre le réchauffement climatique grâce au carbone qu’ils permettront de stocker.

This plot of land located in the Meuse department has been weakened by the combined action of global warming and insect pests. The network of tunnels dug by the bark beetles under the tree bark to feed and reproduce has greatly weakened them.

This project focuses on the natural regeneration of a plot of land weakened by global warming and pests. Located in the Meuse department (Grand Est region), it aims to restore the plot’s forest ecosystem using an agile management method. This approach makes it possible to enhance the existing forest to enable it to adapt to climate change. The local stand will thus be enriched with locally developed species. 
27,000 trees are currently undergoing silvicultural work, in partnership with the town of Ligny-en-Barrois.
The regenerated stand will eventually be more resistant to insect attacks and climatic hazards. And the trees will be able to host a biodiversity and contribute to the fight against global warming thanks to the carbon they will store.
