Close to nature forestry

Close to nature forestry is a forest-management approach that treats the forest as a functioning ecological system rather than simply as a timber plantation. Its objective is to produce wood while maintaining or improving the forest’s capacity to regulate itself, regenerate, support biodiversity, protect soil and water, provide wildlife habitat, and deliver recreational and landscape benefits. The approach seeks to narrow the divide between conventional silviculture and ecological conservation by integrating multiple functions within the same forest area instead of separating land into exclusively productive and exclusively protected zones. The method is associated particularly with the peri-Alpine countries of Europe, including Switzerland, France, Germany, and Slovenia. Its intellectual and practical development draws on sustainable forestry practices that were already emerging in the late nineteenth century, although the modern movement became more organized during the twentieth century. A central premise is that foresters should work with existing tree populations, natural regeneration, ongoing ecological processes, and established forest structures. Human intervention is not eliminated, but is limited to actions intended to accelerate or guide processes that nature would otherwise perform more slowly. Uneven-aged and mixed-species forests are especially important to the approach. In an uneven-aged forest, trees of different ages and sizes occupy the same area, creating a continuous canopy and ongoing regeneration. Individual-tree or group-selection systems, including the German Plenterwald tradition, are commonly associated with this model. Such structures can provide more continuous soil protection, improve habitat conditions, reduce exposure to some natural disturbances, and maintain a diverse vertical and horizontal forest structure. Pro Silva, an organization created after a 1989 meeting in Slovenia, has been an important advocate of these principles. Close to nature forestry normally emphasizes low-intensity, carefully directed thinning rather than clear-cutting or large-scale uniform harvesting. Operations are intended to retain promising trees, avoid damaging remaining stands, limit soil compaction, and prevent excessive light from producing an overly dense understory or undesirable epicormic growth. A frequently cited management pattern is relatively infrequent thinning at low intensity, although the appropriate schedule depends on site conditions, species, stand structure, and management objectives. The approach also addresses the selection of tree species. Native vegetation is treated as the foundation of planning, while the use of introduced or exotic species is controversial. Some close-to-nature advocates reject introduced species altogether; others allow them only where careful qualitative and quantitative trials demonstrate ecological and silvicultural benefits without unacceptable risks to native biodiversity. The possibility that introduced species may become invasive is therefore a central consideration. Herbivore management is another practical issue. Deer and other browsing animals can damage seedlings and young trees, threatening continuous regeneration. This is particularly difficult in uneven-aged forests, where regeneration is ongoing rather than confined to a defined harvest cycle. Excessive wild herbivore populations or unrestricted grazing may therefore conflict with the model. The approach has also been discussed in economic terms. In developed economies, forestry has faced lower timber prices and higher operating costs. Because close to nature forestry generally requires fewer intensive interventions, it may reduce labor and operating requirements. Its proponents also argue that forests managed in this way can develop greater ecological, scenic, and landscape value, potentially supporting public benefits and future payments for ecosystem services. The approach is not a conventional consumer brand or corporate enterprise; it is better understood as a forestry philosophy, silvicultural framework, and management label used by forestry organizations and practitioners.

Close to nature forestry developed as a response to the perceived limitations of forestry systems focused primarily on maximizing timber output. Its underlying idea is that a forest should be managed as an ecosystem whose productivity depends on maintaining living and non-living relationships, including soil conditions, species diversity, regeneration, habitat, water, and resilience to disturbance. The approach is strongly associated with central and Alpine Europe. Germany’s Working Group for the Close to Nature Forestry, known by its German initials ANW, was established in 1950. The organization helped consolidate a movement that favored management based on natural forest structures and processes. The movement gained visibility as ecological awareness increased, concerns grew about damage to regular forest stands, and public expectations expanded beyond wood production to include biodiversity, recreation, landscape quality, and other forest services. Slovenia became an especially important setting for close-to-nature management. A 1948 forestry law that prohibited clear-cutting resulted in many Slovenian forests being managed through methods compatible with continuous cover and natural regeneration. In 1989, ANW promoted a meeting at Robanov Kot in the Julian Alps. Representatives from ten countries participated, and the meeting led to the creation of Pro Silva, an organization dedicated to promoting forest management based on natural processes. Pro Silva later established its headquarters in the French region of Alsace. The principal silvicultural model associated with the movement is the uneven-aged forest. Trees of different ages and dimensions are retained together, and harvesting is conducted through the selection of individual trees or small groups. Advocates argue that this arrangement maintains more stable forest cover, protects soil, supports biodiversity, and provides suitable conditions for wildlife. Low-intensity thinning is used to guide stand development, favor trees with strong future prospects, and maintain a balance between canopy cover and regeneration. The close-to-nature concept has also been developed outside Europe. In the United States, Thomas J. McEvoy presented related ideas in Positive Impact Forestry, connecting the movement with European forestry traditions and with the ecological thinking of Aldo Leopold. The Ecoforestry Institute and related organizations in the United States and Canada have promoted forestry based on ecological principles that overlap substantially with the close-to-nature model. In Britain and Ireland, the related term continuous cover forestry is often used. The framework is not identical everywhere. Some practitioners support uneven-aged, multi-species systems as the preferred model, while others consider high regular forests compatible with close-to-nature objectives if regeneration occurs under generous canopy cover and management avoids severe soil exposure or abrupt ecological change. Views also differ over exotic species. A strict interpretation excludes them, whereas Pro Silva-related guidance may permit carefully evaluated introductions when they complement local conditions and do not threaten natural forest systems. The approach remains constrained by practical factors. Browsing by deer and other herbivores can prevent regeneration, particularly where forests are continuously regenerating. Soil compaction, damage to retained trees, disease, fire, windthrow, and other disturbances must be considered alongside harvesting when assessing sustainability. Economic pressures are also significant, because timber prices and operating costs can make forestry less profitable in developed countries. Supporters argue that lower intervention requirements and the production of broader ecosystem and landscape values may help offset these pressures, although the economic results depend on local markets, forest conditions, and policy arrangements.

  Slovenian restrictions on clear-cutting

  [1]Ecoforestryen.wikipedia.org

  A Slovenian forest law introduced a ban on clear-cutting, contributing to the development and preservation of forest-management practices compatible with continuous cover and close-to-nature principles.

An ecosystem-based alternative to intensive plantation forestry and clear-cutting, combining timber production with biodiversity, habitat, soil, water, recreational, and landscape objectives.

• Silvicultural system

  Uneven-aged forests

  Forests containing trees of different ages and sizes, usually maintained through individual-tree or group selection. The system supports continuous canopy cover, ongoing natural regeneration, habitat complexity, and protection of soil and water. It is a central practical expression of close-to-nature forestry.

• Forest management approach

  Continuous cover forestry

  A related management terminology used especially in Britain and Ireland. It describes harvesting and regeneration practices that avoid extensive clear-cutting and retain forest cover over time, aligning with the close-to-nature emphasis on natural processes and structural continuity.

• Forest operation

  Ecological thinning

  Low-intensity removal of selected trees to guide stand development, favor trees with strong future prospects, maintain appropriate light conditions, and limit damage to soil and retained vegetation. The operation is intended to assist natural processes rather than replace them.
