### 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.

**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.

Douglas

Érable sycomore

Situées sur une ZNIEFF dans la vallée de la Corrèze et de la Vimbelle, les parcelles à reboiser étaient initialement plantées en résineux. L'ancien propriétaire a effectué une coupe rase, aujourd'hui il ne reste que quelques régénérations naturels feuillus non entretenus depuis des années. Le nouveau propriétaire souhaite mener cette forêt vers une futaie irrégulière durablement gérée. Pour se faire, un mélange de feuillus et de résineux (érables sycomores et douglas) sera implanté sur le terrain délaissé. Ce sont donc 2 hectares de terrain qui vont devenir productif en termes de bois. Ce projet de reboisement permettra également la stabilisation du sol et la lutte contre l'érosion et perte de l'humus. 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.

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.

Situated in a ZNIEFF (natural zone of ecological, faunistic and floral interest) area in the Corrèze and Vimbelle valleys, the plots to be reforested were initially planted with coniferous trees. The previous owner carried out clear-cutting, and today only a few natural regenerations remain, of deciduous trees that have been left untended for years. The new owner wants to turn this forest into a sustainably managed irregular high forest. To achieve this, a mixture of deciduous and coniferous trees (sycamore and Douglas maples) will be planted on the abandoned land. This means that 2 hectares of land will become productive in terms of wood. This reforestation project will also help stabilize the soil and combat erosion and humus loss. The growth of this new sustainably-managed forest will capture atmospheric carbon dioxide, thereby combating global warming. The diversity of tree species will also enhance biodiversity.

Hêtre commun

Sapin pectiné

Situées sur une zone montagnarde du parc naturel régional de Millevaches dans le Limousin, les parcelles à reboiser ne présentent pas de signes de régénération. Le peuplement initial de cette forêt était jusque-là monospécifique, c'est-à-dire exclusivement composé d'une seule variété d'arbres, ici, l'épicéa. Un mode gestion risqué pour plusieurs raisons : appauvrissement des sols, baisse de la biodiversité et risque accru d’attaque biologique et aléas climatique. Dans le contexte de dérèglement climatique, il est nécessaire de changer ce modèle de gestion. Dans l'objectif d'irrégularisation de la structure de cette forêt, les arbres seront implantés au sein de trouées, afin d'éviter toute coupe rase. Ce projet d'enrichissement va donc permettre la diversification du massif. Ensuite, l'implantation d'essences adaptées la durabilité de l'habitat forestier. Les arbres stockeront également le carbone atmosphérique, contribuant à la lutte contre le changement climatique.

Located in a mountainous area of the Millevaches Regional Nature Park in the Limousin department, the plots to be reforested show no signs of regeneration. The initial stand of this forest was monospecific, i.e. composed exclusively of a single tree variety, in this case spruce. A risky management method for several reasons: soil impoverishment, reduced biodiversity and increased risk of biological attacks and climatic hazards. In the context of climate change, it is necessary to change this management model. With the aim of irregularizing the structure of this forest, trees will be planted in gaps, to avoid any clear-cutting. This enrichment project will enable the forest to diversify. In addition, the planting of suitable tree species will ensure the sustainability of the forest habitat. The trees will also store atmospheric carbon, helping to combat climate change.

Ce massif du bois d’Abbe, situé en Meurthe-et-Moselle, est principalement composé de chênes. Malheureusement, ce peuplement vieillissant a aujourd’hui besoin d’être renouvelé. Aujourd’hui, 22 500 arbres sont accompagnés par différents travaux sylvicoles, évitant ainsi la récolte du peuplement. Cette méthode, perturbera moins l’écosystème, tout en assurant l’implantation d’essences adaptées aux conditions de la station. Pour ce projet, des cloisonnements seront créés, afin de faciliter les déplacements et les travaux. Des débroussaillages seront effectués afin d’enlever les plantes envahissantes qui pourraient gêner le développement des plants. Cette démarche permettra de diversifier le massif, favorisant ainsi la biodiversité. Par ailleurs, les arbres stockeront du carbone, participant ainsi à la lutte contre le changement climatique.

The Bois d'Abbe forest in Meurthe-et-Moselle is mainly made up of oak trees. Unfortunately, this ageing stand is now in need of renewal. Today, 22,500 trees are being supported by various silvicultural works, thus avoiding the need to harvest the stand. This method is less disruptive to the ecosystem, while ensuring the planting of species adapted to site conditions. For this project, partitions will be created to facilitate movement and work. Clearing will be carried out to remove invasive plants that could hinder the development of the plants. This will help to diversify the planting, thereby promoting biodiversity. The trees will also store carbon, helping to combat climate change.

Dans le cadre du projet, des haies bocagères sont introduites sur une pluralité de parcelles, dont certaines dédiées à l’agriculture. Près de 10 000 mètres linéaires constitués d’essences diversifiées sont plantées, parmi lesquelles l’aubépine, le charme, le cornouiller sanguin, l’érable champêtre, le noisetier, l’orme champêtre, le tilleul, le troène et la viorne. Le rôle des haies est central puisqu’il permettra selon les projets de protéger les cultures, de limiter la dégradation des sols, et d’améliorer les trames vertes, refuges pour la biodiversité locale. Enfin, les arbres stockeront du carbone, participant ainsi à la lutte contre le dérèglement climatique.

The Avesnois Regional Nature Park has been working for several years to improve ecological corridors in its territory in the Nord department (Hauts-de-France). As part of the project, bocage hedges are being introduced on a number of plots, some of which are dedicated to agriculture. Nearly 10,000 linear metres of diverse species are planted, including hawthorn, hornbeam, dogwood, field maple, hazel, field elm, lime, privet and viburnum. Depending on the project, hedges play a central role in protecting crops, limiting soil degradation and improving green screens, which are refuges for local biodiversity. Finally, the trees will store carbon, helping to combat climate change.

Mélèze

Bouleau

À Sornac en Nouvelle-Aquitaine, ce projet se situe au cœur du parc naturel de Millevaches, sur un plateau à plus de 750m d'altitude. Les parcelles concernées ont été abattues par les précédents propriétaires avant d’être récupérées par le nouveau propriétaire en sol nu, plus ou moins enfrichées. Après des travaux de nettoyage, les parcelles accueillent une démarche de restauration des écosystèmes. Des essences comme le douglas, le mélèze et le bouleau sont introduites par îlots pour maintenir une diversité d’espèces sur la zone. Le projet permettra de maintenir un couvert forestier continu, et participera à la reconstitution et la préservation des sols. Les arbres plantés participeront à la formation d’un patrimoine forestier. À terme, le peuplement participera à la lutte contre le réchauffement climatique grâce au stockage de carbone.

In Sornac, in the Nouvelle-Aquitaine region, this project is located in the heart of the Millevaches nature park, on a plateau at an altitude of over 750m. The plots in question were felled by previous owners before being reclaimed by the new owner as bare soil, more or less overgrown. Following a clean-up operation, the plots are now being used for ecosystem restoration. Species such as Douglas fir, larch and birch are introduced in patches to maintain species diversity in the area. The project will maintain a continuous forest cover, helping to reconstitute and preserve the soil. The trees planted will contribute to the formation of a forest heritage. Ultimately, the stand will help fight global warming by storing carbon.

Bouleau commun

Pin maritime

Dans le département de la Gironde, au cœur du parc naturel régional des Landes de Gascogne, ces 5 parcelles forestières s’étendent sur une surface totale de 22 hectares. Composées de pins maritimes, ces monocultures ont été fortement affectées par les ouragans Martin en 1999 et Klaus en 2009, ce qui a poussé l’ancien propriétaire à réaliser des coupes sanitaires. Le projet prévoit de diversifier le massif en implantant divers feuillus aux côtés des pins maritimes. Cette démarche permettra de lutter contre les invasions de chenilles processionnaires, fréquentes dans les environs, mais aussi de protéger la forêt face aux aléas climatiques. Tempêtes et incendies peuvent, en effet, avoir des conséquences désastreuses sur les massifs en particulier les monocultures. Plus résiliente, la forêt pourra stocker du carbone sur le long terme.

In the Gironde department, in the heart of the Regional natural park Landes de Gascogne, these 5 forest plots extend to a total of 22 hectares. Made up of maritime pines, these monocultures have been highly damaged by the storms - Martin in 1999 and Klaus in 2009. This pushed the previous landowner to do sanitation harvest. The project aims at diversifying the forest by introducing diverse deciduous trees to go with the maritime pines. This process will help fight invasions of pine processionary caterpillars, which happen frequently in the area. It will also protect the forest against climate hazards. Storms and wildfires can have disastrous consequences on forests, especially on monocultures. More resilient, the forest will store carbon in the long run.

Située dans la Nièvre, à Montreuillon, ces parcelles forestières anciennement constituées d’épicéas, vont faire l’objet de travaux de RNA visant à assurer l’avenir des arbres. Cette méthode, plus douce et naturelle que la plantation, apportera de multiples bénéfices, en plus de permettre le renouvellement du peuplement. Aujourd’hui, 77 055 arbres font l’objet de travaux sylvicoles visant à favoriser leur croissance dans de bonnes conditions. Cette démarche diversifiera la composition du peuplement, le rendant ainsi plus résistant face aux aléas climatiques et biologiques. La densité d'arbre sera réduite pour laisser de la place aux tiges d’avenir. Des voies d’accès seront aussi mises en place, permettant d’effectuer les travaux sans perturber l’écosystème. Cette gestion favorisera le développement d’une biodiversité, tout en préservant le sol. Par ailleurs, la restauration de cette forêt permettra de stocker du carbone, participant ainsi à la lutte contre le changement climatique. 

This forest is located in the Morvan Regional Nature Park, a highly touristic area where the planting and exploitation of Douglas fir is much criticised, particularly for reasons of landscape, biodiversity and soil protection. The owner is currently faced with the decline of the pectin fir, Douglas fir and spruce, and therefore wishes to work towards an irregularisation of the stand based on the natural regeneration present, and thus obtain a mixed hardwood/softwood stand with a view to moving towards a mosaic forest.

Located in Montreuillon in the Nièvre region, these forest plots, which used to be made up of Spruce trees, will undergo assisted natural regeneration (ANR) work to ensure their future. 
77,055 trees are already undergoing silvicultural work to promote their growth under good conditions. More gentle and natural than planting, the ANR method will allow the renewal of the stand and its diversification to make it more resistant to climatic and biological stresses.
This management will encourage the development of biodiversity, while preserving the soil. And by restoring this forest, it will be able to store carbon to help fight climate change.
