The Landes forest (pronounced [lɑ̃d]; La forêt des Landes in French) in the Landes de Gascogne (las Lanas de Gasconha in the Gascon language), in the historic Gascony natural region of southwestern France now known as Aquitaine, is the largest man-made woodland in Western Europe. The French word, landes and Gascon lanas, mean 'moors' or 'heaths', from Transalpine Gaulish *landa ("uninhabited/uncultivated area"); compare Irish lann, Welsh llan (“enclosure”).[1]

Key Information

Geography

[edit]
Map of Landes of Gascony.

The forest (also known as the 'moors of Gascony', and formerly, the 'moors of Bordeaux') covers a large portion of Landes and Gironde, two of the departments of France; it also spills over into parts of the Lot-et-Garonne department. The sources of several rivers can be found in this region, including the sources of the Leyre, the Boudigau, the Ciron, and the Gat Mort. The largest towns within the forest are Arcachon, Dax, and Mont-de-Marsan.

Origin as a pine plantation

[edit]

The forest is composed mostly of maritime pine, Pinus pinaster. Unlike many other European forests, the Landes forest is almost entirely created and managed by man for industrial purposes. This massive pine plantation was started in the 18th century in the Pays de Buch area of Gironde, to halt erosion and cleanse the soil.

History

[edit]

Most of the region now occupied by the Landes forest was swampy land that was sparsely inhabited until the 19th century, when the 19 June 1857 law ended traditional pastoralism and led to wide scale reforestation, in order to rehabilitate the landscape and provide for regional economic development. Prior to this period, the people of the Landes used stilt-walking to move from place to place in the wet terrain. Since the 1970s, parts of the forest have given way to intensive agriculture (in particular, grain farming.)

The area of the forest is estimated to be around 10,000 square kilometres (3,900 sq mi), of which nine-tenths is exclusively devoted to a monoculture of maritime pines (Pinus pinaster), but, in the centre of this pinhadar (pine plantation in the Gascon dialect of Occitan), there is a natural forest that survives from the post-glacial timbering of this part of southwestern France. There, pines co-exist with other species, chiefly oak, alder, birch, willow, and holly. This mixed temperate forest is most commonly found along watercourses, where the drainage is particularly good. The old-growth forest was probably more extensive prior to the Middle Ages, when a colder, more humid, climate took hold and changed the species composition. Because of the need for wood for fuel and construction, and because of a steady expansion in the grazing of sheep, the aboriginal forest was further depleted between the 15th and 18th centuries.

A major storm in January 2009 damaged approximately 300,000 hectares (740,000 acres) of forest, 90% of which was located in the Landes Forest.[2]

Agriculture and industry

[edit]

Before the mid-19th century, only the breeding of sheep on the moors (and the production of sheep manure as a soil amendment) allowed the cultivation of rye. Because of wet winters, it was necessary to top-dress the land with thatch to preserve it for the next growing season. The disappearance of the moors, because of the expansion of the pine plantations, brought about the end of this herding and wetland grain-growing culture, and the iconic image of shepherds on stilts disappeared as well. The shepherd image was replaced by the image of the resin-collector with his tools.

In the first part of the 20th century, extensive commercial exploitation of wood, paper, and pine resin began, and these industries became an important part of the regional economy. Many local people are still employed in forest-related pursuits, including forestry, sawmills, paper mills, woodcrafts like parquetry and joinery and furniture making, as well the fabrication of paper-based products like cardboard and fiberboard for construction. However, resin-collecting, which required hard labor, has almost completely disappeared because modern chemical processes for producing solvents and other useful chemicals often do not rely on pine resin or pine tar as a precursor. DRT is the largest company in this region that uses the byproducts of pine exploitation.

from Grokipedia
The Landes forest is the largest artificial woodland in , encompassing approximately one million hectares of primarily maritime pine () plantations across the departments of Landes and in southwestern . Originally a landscape of shifting sand dunes, marshes, and heaths prone to and flooding, the forest was systematically developed starting in the late through drainage projects and tree planting initiatives, with major expansion driven by the French law of 19 June 1857 under to stabilize the terrain and promote economic development via resin and timber production. Today, it forms a monoculture-dominated that supports one of 's leading industries, while also harboring diverse understory vegetation such as heather, ferns, and oaks, alongside wetlands, lagoons, and river valleys that foster including over 300 bird species, dragonflies, and migratory cranes. A significant portion—336,100 hectares—falls within the Landes de Gascogne Regional Natural Park, established on 16 October 1970 to preserve its , promote sustainable management, and facilitate activities like canoeing on the Leyre and in protected deltas. The forest faces ongoing challenges from , including increased risks and storm damage, as seen in the devastating 2009 storm that affected 300,000 hectares and the 2022 wildfires that burned over 20,000 hectares in the region, prompting adaptive reforestation efforts to enhance resilience.

Geography

Location and Extent

The Landes forest, also known as the Forêt des Landes de Gascogne, is located in southwestern within the region. It spans the departments of , Landes, and , forming a vast continuous expanse that borders the along the Atlantic coast. This positioning places it in the historic area, where the forest's western edge meets coastal dunes and its eastern limits approach agricultural plains. Covering approximately 10,000 km² (3,900 sq mi) of forested land, the Landes forest represents the largest artificial woodland in , with around 1,000,000 hectares dedicated primarily to production . Its boundaries extend from the Atlantic Ocean's dune systems in the west, including areas near , inland across a sandy plateau to the River valley in the east. The forest is centered around coordinates 44.18°N 0.58°W, encompassing diverse hydrological features such as the sources of the Leyre, Boudigou, and Ciron rivers, which originate within its interior and contribute to regional wetland systems. Key towns situated within or on the periphery of the forest include on the coast, Dax and in the central and southern zones, and Mimizan along the southern edges, serving as gateways for access and local administration. These settlements highlight the forest's integration with human landscapes while underscoring its role as a dominant natural feature in the region.

Physical Characteristics

The Landes forest occupies a vast, flat sandy plain formed from marine deposits and eolian dunes, characterized by low relief and a gentle of approximately 1.25% from southeast to northwest. This terrain features complex microrelief that influences local drainage and distribution, with no prominent hills or valleys except for small incised river channels 10-20 meters deep. Elevations are generally low, ranging from along the coast to 150 meters in the east, with an average of 50-70 meters across the plateau; coastal dunes reach heights of up to 25 meters. The soils are predominantly podzols and spodosols, derived from sandy parent materials with high content, resulting in poor, acidic conditions ( 4.5-5) and low nutrient availability. These soils consist mainly of (about 95%), with minimal clay (2.4%) and (2.9%), making them infertile and prone to leaching, though drainage improvements render them suitable for maritime cultivation. Hydromorphic variants, such as redoxisols and reductisols, occur in wetter depressions. The is oceanic and temperate Atlantic, with mild winters (average temperatures of 5-10°C), warm summers (20-25°C), and an annual mean of about 12°C. is abundant, totaling 800-1,200 mm annually, concentrated in spring and autumn maxima, while frequent storms, driven by Atlantic influences, contribute to high winds and occasional summer droughts. Hydrologically, the forest features a shallow aquifer (10-130 deep) and poor natural drainage due to the flat terrain, leading to widespread swamps, peat bogs, and lagunes, particularly in the Grande Lande region. Key river systems include the Eyre (formed by the of the Grande and Petite Leyre), which traverses the area with an average flow of 19.3 m³/s and supports habitats. These features historically included mobile dune encroachment along the , which was stabilized through pine plantations initiated by the 1857 law.

History

Early Conditions and Traditional Uses

Before the 19th century, the Landes region consisted of vast, flat expanses of swampy moors known as landes, interspersed with shifting coastal sand dunes and wet pastures that rendered much of the area infertile and sparsely vegetated with stunted bushes and dry heath. These landscapes were marshy during winter, accumulating stagnant waters that fostered unhealthy conditions, while summer droughts and periodic burnings for grazing exacerbated erosion and flooding risks, leading contemporaries to describe the area as a desolate "desert" or "empty space," often likened to the "French Sahara." The traditional economy revolved around and limited resource extraction, with nomadic shepherding as the dominant activity. Shepherds, often on foot or using wooden called chassons or tchangues (up to 1.2 meters high) to traverse the muddy terrain, managed large flocks of sheep—estimated at around one million by the mid-19th century—for and production, roaming up to 20 kilometers daily across communal moors to graze on the poor, sandy soils enriched by sheep manure. Sheep breeding supported a subsistence , supplemented by modest cultivation of and on small 3- to 5-hectare plots without periods, as well as from scattered wild maritime pines—a practice dating to the —and occasional harvesting from the wetlands for fuel. Population density remained extremely low, under 10 people per square kilometer in the early 1800s, reflecting the harsh environment and isolation, with inhabitants clustered in small villages near rivers like the Adour and engaging in seasonal tied to Gascon . This sparse settlement pattern underscored the region's perception as a wasteland, prompting initial 18th-century experiments in dune stabilization in the Pays de Buch area by figures such as the de Ruat family, who planted vegetation to curb sand encroachment. These efforts foreshadowed later large-scale pine plantations but remained localized before state intervention.

Reforestation and Development

Early efforts to stabilize the shifting dunes and marshy terrains of the Landes region began in the , with engineer Nicolas Brémontier conducting pioneering experiments in planting maritime pines () to fix coastal sands in the basin between 1784 and the early 1800s. These initiatives, building on smaller-scale trials, demonstrated the pine's effectiveness in anchoring dunes and improving soil conditions, laying the groundwork for broader strategies. The systematic transformation accelerated with the French government's Law of 19 June 1857, enacted under , which mandated the of approximately 1 million hectares of communal moors and dunes across the and Landes departments to combat erosion, drain swamps, and promote economic development. Funded initially by the state and later sustained through timber and resin sales, the program was directed by hydraulic engineers such as Henri Crouzet from the Corps des Ponts et Chaussées, who oversaw the implementation of drainage networks and . Key methods included extensive swamp drainage via a grid of ditches and canals—such as elements of the Canal des Landes system—and the planting of maritime pines in straight rows to facilitate access and resin collection. Infrastructure for resin-tapping, including V-shaped incisions on trunks to collect gomme-résine, was integrated from the outset to ensure financial viability. By 1900, these efforts had resulted in over 800,000 hectares of planted forest, fulfilling much of Napoleon III's vision for modernizing the region's economy through sustainable timber production and aligning with broader Second Empire goals of infrastructural and agricultural reform. Socially, the reforestation shifted the local population from —where shepherds herded sheep on across wet moors—to settled communities, reducing traditional numbers from around 1 million sheep in 1850 to 295,000 by 1890 and diminishing prevalence through . This transition also fostered a burgeoning pine resin economy, with gomme-résine extraction providing income for smallholders and fueling industries for and production, often through leased tapping operations that supported local livelihoods.

20th and 21st Century Events

In the early , the industry in the Landes forest reached its peak, with production exceeding 1.5 million hectoliters annually following , supporting thousands of resiniers and numerous factories across the region. This era of prosperity ended by the 1930s due to economic crises and competition, accelerating after with the rise of synthetic alternatives like petroleum-based resins, which proved cheaper and more reliable, leading to the closure of the last resin factory in 1992. During both World Wars, the forest faced intensified for timber to support needs; in , Canadian forestry units harvested approximately 1.5 million pines from the Landes and adjacent forests between 1917 and 1919 to supply Allied front lines. brought further devastation through uncontrolled blazes in the 1940s that razed over 66,000 hectares in 1942 alone, including 45,000 in a single month. Post-war reconstruction shifted the forest's focus to wood and paper production, with the marking an intensification of practices, where maritime pines are harvested on a 40-year rotation cycle to maximize timber yield. The 21st century brought major natural disruptions, beginning with the devastating Storm Klaus on January 24, 2009, which affected over 234,000 hectares of forest—primarily in the Landes de Gascogne—with damage exceeding 40% in many stands, resulting in 42.5 million cubic meters of fallen timber equivalent to several years of normal harvest. The storm's economic toll reached €1-1.4 billion in insured losses alone, prompting extensive salvage logging operations and a massive replanting effort involving over 250 million seedlings across 200,000+ hectares. In the 2010s and 2020s, wildfires added to the challenges, such as the 2017 fires that burned nearly 1,000 hectares of pine stands near the Landes border, and the 2022 mega-fires in the and Landes de Gascogne region that destroyed over 30,000 hectares of forest. Recurrent outbreaks of the pine processionary moth (Thaumetopoea pityocampa) defoliated thousands of trees, exacerbating tree stress in weakened areas. subsidies, totaling hundreds of millions of euros through funds like the European Agricultural Fund for , supported restoration post-Klaus, replanting and recovery. Recent years have seen prolonged droughts stressing the forest, while emerging pests have added to vulnerabilities; in October 2025, the pine wood nematode (Bursaphelenchus xylophilus) was detected in Seignosse, prompting mandatory abatement of affected pines within a 500-meter zone and restrictions on wood movement to prevent spread. These events have underscored the forest's economic reliance on timber, where post-disaster salvage operations temporarily boost output but strain local processing capacities.

Ecology and Biodiversity

Forest Composition

The Landes forest is predominantly composed of maritime pine (Pinus pinaster), which accounts for approximately 87% of the total standing volume and forms the backbone of its artificial plantation structure. This species was extensively planted starting in the to stabilize sandy soils and dunes, resulting in vast even-aged monocultures managed on rotation cycles typically lasting 35 to 50 years, depending on the intended timber products such as or pulp. The uniform planting density and silvicultural practices create a highly engineered , with limited natural regeneration and a focus on productivity over . The in these pine-dominated stands is notably sparse, primarily due to the dense canopy that limits light penetration to the forest floor. Common species include bracken fern (), heather (Calluna vulgaris), and various grasses, which form a low-lying layer adapted to the acidic, nutrient-poor conditions. These contribute minimally to overall but play roles in and microhabitat provision, though their growth is often suppressed in mature stands. Species diversity within the forest remains low, reflecting its plantation origins, with native broadleaf trees comprising only about 13% of the volume, including scattered oaks (Quercus spp.) and birches (Betula spp.) that represent roughly 5-10% in mixed areas. are minimal, confined to occasional non-native shrubs or invasives, while preserved peat bog remnants in undrained zones harbor ancient such as mosses and sundews, remnants of the pre-plantation wetland . Structurally, the forest features uniform stands of maritime pines reaching 20-30 meters in height at maturity, with straight trunks and a closed canopy that promotes even growth across large areas. Variations occur between coastal and inland zones, where coastal stands are sparser and more wind-exposed, while inland areas support denser, taller formations due to reduced exposure and slightly better moisture retention. Maritime pines are well-adapted to the forest's poor, sandy soils through symbiotic mycorrhizal associations with fungi, which enhance nutrient uptake—particularly and —from the infertile substrates, enabling survival and growth where other would struggle. This adaptation underpins the forest's productivity but also contributes to its vulnerability in monocultural settings.

Wildlife and Flora

The Landes de Gascogne Regional Natural Park supports a diverse array of mammals, including (Capreolus capreolus), (Cervus elaphus), (Sus scrofa), red foxes (Vulpes vulpes), and European badgers (Meles meles), which thrive in the forest's mosaic of woodlands and open areas. These contribute to the park's role as a corridor, with populations of deer facilitating ecological connectivity between habitats. Other notable mammals include the European (Lutra lutra) along riverine zones and various bats such as the barbastelle (Barbastella barbastellus), (Rhinolophus ferrumequinum), and greater noctule (Nyctalus lasiopterus), which utilize tree cavities and wetlands for roosting and foraging. The park's avifauna is particularly rich, with over 300 bird species recorded, including rare and protected ones like the (Dryocopus martius), which has colonized the mature pine stands in recent decades. Migratory raptors such as the short-toed snake-eagle (Circaetus gallicus) and (Pandion haliaetus) frequent the area, while wetlands and lagoons host abundant waterfowl, including the (Grus grus) and various waders like the whimbrel (Numenius phaeopus). Forest specialists like the (Caprimulgus europaeus), golden oriole (Oriolus oriolus), and (Sylvia undata) further highlight the site's importance for breeding and passage birds. Reptiles and insects add to the understory's vibrancy, with species such as the asp viper (Vipera aspis), viviparous lizard (Zootoca vivipara), and European pond turtle (Emys orbicularis) inhabiting damp forest edges and peat bogs. Insect diversity is notable, encompassing processionary caterpillars (Thaumetopoea pityocampa), diverse beetles like the great capricorn (Cerambyx cerdo), and butterflies including the large copper (Lycaena dispar); the park records over 60% of France's dragonfly species (Odonata) in its wetlands. Riverine zones along the Leyre River serve as key hotspots for amphibians, supporting species like the Iberian tree frog (Hyla molleri) and fire salamander (Salamandra salamandra), which rely on these moist corridors for breeding. Beyond the dominant maritime pines, the forest's flora includes over 20 species of wild orchids, such as pyramidal orchid () and bee orchid (), scattered in clearings and grassy margins. Peat bog areas harbor carnivorous plants reminiscent of species, notably intermediate sundew (Drosera intermedia) and 16 types of sphagnum mosses ( spp.), which create acidic, nutrient-poor niches. Edible mushrooms like the red-footed boletus () and king bolete () emerge in autumn under oaks and pines, enhancing the understory's mycorrhizal networks. Overall, these elements underscore the park's status as a vital refuge amid the pine , fostering habitats for non-arboreal life.

Ecological Issues

The Landes forest, dominated by even-aged stands of maritime pine (Pinus pinaster), exhibits high vulnerability to biotic disturbances due to its uniform composition, which facilitates rapid spread of species-specific pests and pathogens. The pine processionary moth (Thaumetopoea pityocampa) is a primary defoliator, with cyclical outbreaks occurring approximately every seven years and causing up to 93% reduction in radial growth through needle consumption, though rarely leading to tree mortality. Similarly, the pine weevil (Hylobius abietis) infests young plantations post-harvesting, resulting in 50-80% tree mortality without intervention, while the root rot fungus Heterobasidion annosum induces disseminated decay and mortality in stumps and roots, contributing to widespread economic losses estimated at €800 million annually across European pine forests. These risks are amplified in monocultures, as the lack of limits natural resistance mechanisms, such as associational effects from non-host plants that could disrupt pest host location. Wildfires pose a recurrent threat to the forest, exacerbated by the resinous from maritime , which accumulates flammable and bark, promoting rapid ignition and intense surface fires. Prior to the , annual burned areas in the Landes typically ranged from 1,000 to 2,000 hectares, with notable events including 1,100 hectares in 2017, reflecting a of frequent but relatively contained incidents influenced by dry conditions and human ignition sources. However, the 2022 wildfire season was exceptional, burning over 20,000 hectares in the Landes forest and causing significant loss and impacts. This litter-driven flammability contributes to soil and volatilization, hindering post-fire regeneration in the sandy substrates. Intensive harvesting practices in the Landes accelerate soil degradation through nutrient depletion and , as whole-tree removal extracts essential elements like , , and without adequate replenishment in the nutrient-poor, acidic podzols. Clear-cutting operations further exacerbate , with exposed sandy soils losing layers via and runoff, leading to reduced and compaction that impairs penetration in subsequent rotations. These processes diminish long-term site , as decline and acidification compound the baseline limitations of the region's low soils. Historical drainage efforts to convert former wetlands into productive forest land have resulted in over-drainage of peat-rich areas, causing peat drying, subsidence, and associated carbon losses through enhanced oxidation and decomposition. This alteration lowers water tables, exposing peat to aerobic conditions that release stored carbon as CO₂, with drained peatlands globally emitting up to 12 tons of CO₂ equivalent per hectare annually, a dynamic applicable to the Landes' modified hydrology. Invasive species, such as Himalayan balsam (Impatiens glandulifera), further disrupt wetland remnants by outcompeting natives along drainage channels, promoting bank erosion and altering hydrological flows. Biodiversity in the Landes is markedly reduced compared to natural forests due to the dominance of a single tree species and simplified understory, limiting habitat niches for understory plants, insects, and vertebrates. Road networks fragment the landscape, creating edges that favor generalist species while isolating core habitats, thereby reducing connectivity and increasing extinction risks for forest specialists. Storms, such as the 2009 Cyclone Klaus, have occasionally caused extensive windthrow, felling 40 million cubic meters of timber across 600,000 hectares in the Landes, highlighting the forest's structural vulnerability to high winds.

Economy and Human Use

Forestry Industry

The forestry industry in the Landes forest, centered on the maritime pine (Pinus pinaster), plays a pivotal economic role through timber production and processing. The region yields approximately 10 million cubic meters of timber annually, accounting for over 25% of France's total wood production, with maritime pine comprising about 56% of the regional harvest. This output primarily supports construction materials, pulp for , and wood panels, leveraging the pine's straight grain and content for durable applications. Key products include sawn wood for structural timber, for packaging and furniture, and pulp that feeds a substantial portion of the French industry, with local mills like Gascogne Papier sourcing over 100,000 tons annually exclusively from the surrounding forests. Byproducts from pine , such as historically extracted for naval stores, have shifted toward modern essential oils and derivatives used in adhesives, fragrances, and nutraceuticals; the decline in traditional resin tapping since the late reflects evolving market demands. Prominent companies drive this sector, including DRT (Dérivés Résiniques et Terpéniques), which specializes in resin-based chemicals from local sources, and major processing facilities such as sawmills and plants in Tonneins and Saint-Sever. Approximately 91% of the area is privately owned, fostering a fragmented yet productive managed by around 40,000 proprietors who oversee the majority of operations. The industry sustains about 34,000 direct jobs in harvesting, , and , contributing an value of approximately €1.6 billion annually as of 2016 through shipments of timber and derived products to and beyond. Common practices involve clear-cutting mature stands followed by systematic replanting, enabling a cycle of 45-50 years suited to the sandy soils; is bolstered by PEFC , covering a majority of the harvested wood to ensure environmental and social standards.

Tourism and Recreation

The Landes forest attracts a significant number of visitors seeking outdoor leisure and experiences, with tourism peaking during the summer months due to its mild climate and proximity to the Atlantic coast. Integrated with nearby coastal sites like the Dune du Pilat, which draws over two million visitors annually for its panoramic views of the forest and ocean, the woodland serves as a natural extension for exploration, combining forested trails with dune landscapes. Key attractions include extensive hiking trails, such as sections of the GR8 coastal long-distance path that traverse the forest from Hourtin to , offering moderate routes through pines and dunes spanning approximately 86 kilometers in the region. Cycling enthusiasts utilize over 2,300 kilometers of marked cycle paths, including the Vélodyssée 1 route, which winds through the forest's shaded avenues. Horse riding is also popular, with dedicated equestrian trails allowing riders to navigate the sandy undergrowth. Adventure seekers can experience canopy walks via tree-climbing courses and aerial circuits in areas like Léon and Saint Julien en Born, providing elevated views of the pine canopy for all ages. Arboretums such as the Arboretum d'Ychoux, nestled within the pine forest, showcase diverse tree collections amid wetlands, offering educational strolls through native and exotic species. Recreational activities emphasize the forest's natural appeal, including along designated trails where species like grey herons and cranes can be observed in reserves such as Courant d'Huchet. Mushroom is a seasonal pursuit from late summer to autumn, with visitors collecting edibles like cèpes under the pines, subject to annual permits issued by local authorities to ensure sustainable harvesting. Demonstrations of traditional stilt-walking, a historical practice of Landes shepherds known as "tchangues," occur at regional festivals, highlighting amid the woodland setting. In February 2025, the Landes de Gascogne Regional Natural Park, encompassing much of the forest, was designated an International Dark Sky Reserve, enhancing opportunities for stargazing with observable views of up to 4,000 stars on clear nights. Recovery efforts following the 2022 wildfires have bolstered resilient tourism infrastructure, promoting sustainable access to affected areas. Supporting infrastructure includes more than 3,500 kilometers of marked paths for , , and horseback riding, facilitating safe access across the vast woodland. Numerous campsites and eco-lodges dot the area, such as those near Lake Léon, providing shaded accommodations integrated with the forest environment. Events like the annual de la Nature in May promote through guided walks and family-oriented forest activities. contributes substantially to the regional economy, bolstering local development through sustainable practices in the Landes de Gascogne Regional Natural Park, which emphasizes "green" branding to attract eco-conscious travelers.

Other Economic Activities

The Landes forest environment supports ancillary agricultural activities on its cleared margins and adjacent lands, where crops such as and sunflowers are cultivated, contributing to the region's specialization in field crops. These practices occupy about 18% of the massif's and reflect ongoing diversification from historical land uses. Remnants of traditional persist in some areas, though the sector has significantly declined since the due to falling demand and land abandonment, paving the way for . is another key activity, with the Landes hosting productive hives producing notable quantities of forest honey from heather (Calluna vulgaris and Erica spp.) and polyfloral sources, which forms part of Nouvelle-Aquitaine's annual honey output. Renewable energy initiatives leverage the forest's resources, particularly through from wood waste, which has seen significant growth in demand since 2010, contributing to regional heating and energy needs and aligning with Nouvelle-Aquitaine's goals to exceed production relative to consumption by 2050. Wind farms are developed in open areas near the forest, such as projects in and , enhancing diversification into clean energy without encroaching on core woodland. Food processing industries, notably Armagnac distillation, draw on the forest's oak edges for aging barrels, with chêne pédonculé () from Landes woodlands imparting and flavors during the eau-de-vie maturation process. This activity underscores the forest's role in supporting high-value agro-food products in . The broader forest economy indirectly bolsters regional GDP through linked sectors like agri-food and , following diversification after the 1930s resin industry decline, when gemmage (resin tapping) waned due to synthetic alternatives and market shifts. Approximately 10,000 jobs in agri-food and stem from these interlinkages, aided by EU funds for transitions that promote sustainable and agricultural .

Management and Future Challenges

Current Management Practices

The Landes forest, covering approximately one million hectares in southwestern , is predominantly under private ownership, accounting for about 75% of the area, with 15% managed communally and 10% under state control. This fragmented ownership structure influences , where operations are coordinated through long-term 40-year cycles involving initial planting of maritime pine seedlings, periodic to promote growth, and final clear-cutting at maturity. These cycles ensure sustained timber production while adapting to site-specific conditions, such as sandy soils requiring careful spacing during planting. Harvesting relies on mechanical methods, including heavy machinery for and extraction to minimize disturbance in the forest's fragile ecosystems. Pest monitoring incorporates drone technology for early detection of threats like pine processionary moth infestations, enabling targeted interventions. In nutrient-poor areas, selective fertilization with organic amendments supports tree vigor without widespread application, aligning with sustainable intensification goals. emphasizes biological controls and cultural practices over broad-spectrum chemicals, reducing environmental risks across the forest. Governance is shaped by the French Forest Code, which includes provisions for sustainability. Additionally, subsidies under the European Union's incentivize sustainable practices, such as reduced and biodiversity-friendly thinning, providing financial support to private and communal owners for compliance. On a broader scale, annual replanting efforts help maintain the forest's productive capacity post-events like the 2009 storm recovery. Advanced tools like (GIS) mapping are integral for stand assessment, integrating satellite data such as imagery to evaluate growth, health, and harvest readiness across fragmented properties. Certification under schemes like PEFC covers approximately 80% of the forest area, verifying adherence to these practices through independent audits focused on chain-of-custody and environmental standards.

Conservation Efforts

The Landes de Gascogne Regional Natural Park, established in 1970, spans 336,100 hectares (3,361 km²) and serves as a key protected area dedicated to preserving the forest's unique ecosystems, including pine woodlands and associated wetlands. This park integrates conservation with sustainable development, focusing on maintaining biodiversity amid historical monoculture forestry. Complementing this, Natura 2000 sites cover significant portions of the region's wetlands, safeguarding habitats for migratory birds and rare flora through regulated management plans that limit drainage and promote natural hydrology. Key initiatives include the SUPERB project, running from 2021 to 2025, which targets restoration in the region of the Landes forest by implementing mixed planting strategies, such as integrating broadleaved species into pine-dominated stands to enhance resilience and habitat diversity across a 20,000-hectare pilot landscape. Additionally, EU-funded programs support peat bog revival efforts, involving rewetting techniques and vegetation recovery to restore carbon-storing wetlands degraded by past agricultural and forestry activities. Conservation goals emphasize increasing in forest cover, alongside developing anti-fragmentation corridors to connect isolated habitats and facilitate movement. Public is advanced through interpretive trails and visitor centers that highlight ecological restoration, fostering community involvement in monitoring and protection activities. Partnerships between the Office National des Forêts (ONF), France's National Forest Office, and NGOs such as the WWF drive these efforts, coordinating on-site interventions and policy advocacy. Funding from grants under the LIFE and frameworks supports these collaborative projects. Notable achievements include efforts to manage populations and remove invasives to aid native recovery and reduce ecological threats.

Climate Change Impacts and Adaptation

The Landes forest, predominantly composed of maritime plantations, has experienced significant observed impacts from , particularly intensified and heatwaves between 2022 and 2025. These events led to substantial tree mortality, with French forest mortality rates overall rising 80% over the past decade, driven by prolonged dry conditions that reduced by approximately 30% in 2022 compared to previous years like 2018. In the Landes region specifically, the 2022 summer heatwave and contributed to massive wildfires that burned over 30,000 hectares, exacerbating dieback through water stress and heat-induced physiological damage. Growth reductions in maritime stands averaged around 20% during this period, as measured by net primary productivity declines in southern French forests, highlighting the vulnerability of systems to . Fire risk in the Landes has also escalated markedly, with danger conditions showing a substantial increase under anthropogenic ; the 2022 burnt area was 16 times the 2006–2021 average, attributed to compounded hot, dry, and windy conditions. Projections indicate further deterioration, with maritime productivity expected to peak mid-century under moderate emissions scenarios like RCP 4.5 before declining due to rising temperatures and reduced , while under high-emissions RCP 8.5, continuous declines could drop growth below current levels by 2050, increasing inter-annual variability. Foresight studies for the Landes de Gascogne forest by 2050 emphasize the need for diversification to counter these trends, projecting that without adaptation, frequency could reduce viable habitats by up to 10% in rainfall. The currently acts as a net at approximately 1.6 tC/ha/year through accumulation, though historical drainage has released stored emissions, and unmanaged degradation risks tipping it into a net source amid rising disturbances. Adaptation strategies focus on enhancing resilience through diversification and innovations. Efforts include introducing drought-resistant broadleaf , such as oaks and black locust, aiming for mixed stands comprising up to 30% broadleaves by 2040 to buffer against and improve stability, as outlined in regional foresight scenarios. Pilot systems are being tested in vulnerable stands to mitigate stress during establishment phases, while programs target heat- and drought-tolerant maritime pine varieties to maintain productive monocultures where feasible. These measures align with the EU Forest Strategy for 2030, which promotes resilient, biodiverse forests through incentives and to combat climate extremes. However, challenges persist, including economic trade-offs from reduced timber yields in diversified systems and the need for flexible policies, with 2025 initiatives emphasizing genetic improvement to balance resilience and productivity in pine-dominated landscapes.
