Introduction

  • The coppice system is a traditional method of silviculture that involves the regular cutting of trees or shrubs at ground level to stimulate the growth of new shoots. This system has been practiced for centuries and is particularly useful for the production of wood fuel, poles, and other small-diameter timber products. 

Objectives of Coppice System

  • Sustainable wood production: The primary objective of the coppice system is to ensure a continuous and sustainable supply of wood products. By periodically cutting back the trees, new shoots are encouraged to grow, resulting in a renewable source of timber.
  • Maximizing land productivity: Coppicing allows for the efficient use of land by utilizing the same area for multiple rotations of tree growth. This maximizes the productivity of the land and ensures a continuous supply of wood without the need for extensive land clearing.
  • Biodiversity conservation: Coppice systems can promote biodiversity by creating a diverse range of habitats. The regrowth of trees after cutting provides opportunities for various plant and animal species to thrive, enhancing the overall ecological value of the area.
  • Soil protection and improvement: The regular cutting and regrowth of trees in the coppice system can help protect and improve the soil. The removal of older trees allows more sunlight to reach the forest floor, promoting the growth of understory vegetation and preventing soil erosion.
  • Carbon sequestration: Coppice systems can contribute to carbon sequestration by promoting rapid tree growth. As the new shoots grow, they absorb carbon dioxide from the atmosphere, helping to mitigate climate change.
  • Economic benefits: The coppice system can provide economic benefits to local communities by creating opportunities for sustainable forestry practices. It can support local industries such as timber production, firewood, and other wood-based products, contributing to rural livelihoods.
  • Wildlife habitat creation: The regrowth of trees in the coppice system provides valuable habitat for various wildlife species. The diverse structure of the coppice stands, with different age classes and vegetation layers, offers nesting sites, food sources, and shelter for a wide range of animals.
  • Landscape aesthetics: Coppice systems can enhance the visual appeal of landscapes by creating a mosaic of different tree heights and densities. This can contribute to the overall beauty and diversity of the natural environment.
  • Educational and recreational opportunities: Coppice systems can serve as educational and recreational spaces, allowing people to learn about sustainable forestry practices and enjoy nature. They can be used for activities such as hiking, birdwatching, and nature photography.
  • Cultural and historical preservation: Coppice systems have been used for centuries and are often associated with traditional land management practices. By maintaining and promoting coppice systems, cultural and historical heritage can be preserved, connecting present generations with the past.

Principles of Coppice System

  • Regeneration through cutting: The coppice system involves the periodic cutting of trees or shrubs at or near ground level to stimulate regrowth from the stump or root system.
  • Multiple stems: The coppice system aims to produce multiple stems from each individual tree or shrub, resulting in a dense stand of regrowth.
  • Rotation period: The coppice system follows a specific rotation period, which is the time interval between successive cuttings. This period can vary depending on the species and management objectives.
  • Sustainable management: The coppice system is designed to be sustainable, as it allows for the continuous production of wood or other forest products without the need for complete tree removal.
  • Selection of species: The choice of species for coppicing depends on their ability to regenerate vigorously from the stump or root system. Species with good coppicing ability are preferred.
  • Coppice stool management: The coppice system requires proper management of the coppice stools, which are the remaining stumps or root systems after cutting. These stools need to be protected from damage and disease to ensure successful regrowth.
  • Thinning and spacing: Thinning is often necessary in coppice stands to remove weaker or overcrowded stems, allowing the remaining stems to grow more vigorously. Proper spacing between coppice stools is also important to ensure optimal growth and resource utilization.
  • Harvesting and utilization: The coppice system allows for regular harvesting of the regrowth, which can be used for various purposes such as fuelwood, timber, or non-timber forest products. The harvested material should be utilized efficiently to maximize the benefits of the coppice system.
  • Biodiversity conservation: Coppice systems can contribute to biodiversity conservation by providing habitat for a variety of plant and animal species. The presence of different age classes and structural diversity within coppice stands enhances ecological diversity.
  • Adaptability to site conditions: The coppice system can be adapted to different site conditions, including soil types, climate, and topography. Proper site selection and management practices are essential to ensure the success of the coppice system.

Types of Coppice System

1. Simple Coppice System:

  • In this system, all the stems of a tree are cut down at the ground level.
  • New shoots emerge from the stump and grow into new trees.
  • This system is commonly used for species that have the ability to regenerate vigorously from the stump, such as oak and chestnut.

2. Coppice with Standards:

  • In this system, a few selected trees are left to grow to their full height and maturity, known as standards.
  • The remaining trees are cut down periodically to encourage the growth of new shoots.
  • This system provides a mix of mature trees for timber production and younger shoots for other purposes like firewood or charcoal.

3. Compound Coppice System:

  • This system combines both simple coppice and coppice with standards.
  • Some trees are cut down to ground level for regrowth, while others are allowed to grow into standards.
  • This system provides a diverse range of products, including timber, firewood, and other non-timber forest products.

4. High Forest Coppice System:

  • In this system, the coppice shoots are allowed to grow for a longer period before being harvested.
  • The trees are cut down at a higher height, typically above the reach of browsing animals.
  • This system aims to produce larger diameter timber and is suitable for species that can tolerate shade, such as beech and hornbeam.

5. Coppice Rotation System:

  • This system involves dividing the forest into compartments and cutting each compartment in a rotational sequence.
  • Each compartment is cut at regular intervals, allowing the shoots to regenerate and grow before the next rotation.
  • This system ensures a continuous supply of wood products while maintaining the overall health and productivity of the forest.

6. Coppice Conversion System:

  • This system involves converting an existing coppice stand into a high forest stand.
  • It requires selective thinning and removal of some coppice shoots to allow the remaining trees to grow into a high forest structure.
  • This system is used when the market demand for larger diameter timber increases or when the coppice stand becomes less productive.

7. Continuous Cover Coppice System:

  • In this system, the forest is managed to maintain a continuous cover of trees at all times.
  • Only a portion of the trees is cut down periodically, allowing the remaining trees to provide shade and shelter for the regenerating shoots.
  • This system aims to mimic natural forest dynamics and is suitable for species that prefer a more stable and diverse habitat.

Coppice with Standard System

1. Definition:

  • The coppice with standard system is a silvicultural practice that combines the regeneration of a coppice stand with the establishment of a few standard trees within the same area.
  • It involves the periodic cutting of the coppice shoots for fuelwood or other purposes, while allowing the standard trees to grow and develop into larger timber trees.

2. Regeneration:

  • The system starts with the establishment of a coppice stand through the cutting or clear-felling of the existing trees.
  • The stumps or root systems of the cut trees sprout new shoots, which form the coppice regeneration.
  • The coppice shoots are usually harvested after a certain period, typically ranging from 3 to 20 years, depending on the species and desired product.

3. Standard Trees:

  • Alongside the coppice regeneration, a few selected standard trees are retained and managed to grow into larger timber trees.
  • These standard trees are usually of high-quality timber species or have other desirable characteristics.
  • The standard trees are spaced adequately to allow them to develop a well-formed crown and straight stem.

4. Advantages:

  • The coppice with standard system provides a continuous supply of fuelwood or other products from the coppice shoots.
  • The standard trees offer the potential for higher-value timber production.
  • The system promotes biodiversity by providing different habitats for various species, including both shade-tolerant and light-demanding species.

5. Management:

  • The management of the coppice with standard system involves periodic cutting of the coppice shoots while ensuring the growth and development of the standard trees.
  • The cutting cycle for the coppice shoots is determined based on the desired product and the growth characteristics of the species.
  • The standard trees may require selective thinning or pruning to enhance their growth and form.

6. Suitability:

  • The coppice with standard system is suitable for species that have the ability to regenerate vigorously from the stump or root system.
  • It is commonly used for fuelwood production, but can also be applied for other products such as poles, stakes, or small-diameter timber.
  • The system is adaptable to different site conditions and can be implemented in various forest types.

Process of Coppice System

1. Definition and Purpose:

  • The coppice system is a method of forest management where trees are cut down to the stump and allowed to regrow from the remaining root system.
  • The purpose of the coppice system is to produce multiple stems or shoots from a single tree, resulting in a sustainable and continuous supply of wood or other forest products.

2. Selection of Species:

  • Certain tree species are more suitable for coppicing due to their ability to regenerate vigorously from the stump.
  • Common species used in coppice systems include oak, ash, hazel, willow, and chestnut.

3. Initial Cutting:

  • The first step in the coppice system is the initial cutting, where the trees are felled close to the ground, leaving a stump or "stool" behind.
  • The cutting is usually done during the dormant season to minimize damage to the remaining root system.

4. Regrowth and Management:

  • After the initial cutting, the stumps sprout new shoots, known as coppice shoots or "stools."
  • These shoots are allowed to grow for a specific period, typically ranging from 3 to 20 years, depending on the desired product and management objectives.
  • During this period, the coppice shoots are managed through thinning and pruning to promote healthy growth and prevent overcrowding.

5. Harvesting and Rotation:

  • Once the coppice shoots have reached the desired size or age, they are harvested by cutting them close to the ground.
  • The harvested material can be used for various purposes, such as firewood, charcoal, poles, or craftwood.
  • The rotation period, or the time between successive cuttings, varies depending on the species, site conditions, and market demand.

6. Regeneration and Succession:

  • After each cutting, new shoots emerge from the stumps, ensuring the continuous regeneration of the coppice stand.
  • Over time, the composition and structure of the coppice stand may change as different species or age classes dominate the area.
  • Proper management practices, including periodic thinning and regeneration techniques, are essential to maintain the health and productivity of the coppice system.

7. Benefits and Limitations:

  • The coppice system offers several benefits, including increased wood production, improved biodiversity, and enhanced habitat for wildlife.
  • It can also provide a sustainable source of renewable energy and contribute to carbon sequestration.
  • However, the coppice system may have limitations in terms of reduced timber quality, increased vulnerability to pests and diseases, and the need for regular management interventions.

8. Modern Applications:

  • While the traditional coppice system has been practiced for centuries, modern applications include agroforestry systems, biomass production, and ecological restoration projects.
  • The coppice system can be adapted and integrated with other land uses to maximize its benefits and address specific environmental or socioeconomic objectives.

Techniques of Coppice System

1. Coppice regeneration:

  • Cutting the trees or shrubs close to the ground level to stimulate regrowth from the stump or root system.
  • Commonly used for species that have the ability to resprout vigorously, such as oak, ash, willow, and hazel.

2. Stool coppicing:

  • Involves cutting the tree or shrub at a higher level, leaving a portion of the stem intact above the ground.
  • Allows for the production of larger diameter stems and longer rotation periods compared to coppice regeneration.
  • Commonly used for species like eucalyptus and poplar.

3. Coppice with standards:

  • Combines the benefits of coppice regeneration and high forest management.
  • Involves maintaining a coppice understorey while allowing selected trees to grow into larger, high-quality timber.
  • Standards are usually selected for their timber value or ecological importance.

4. Single-stem coppice:

  • Involves allowing only one stem to grow from each stump or root system.
  • Promotes the production of larger diameter stems and longer rotation periods compared to traditional coppice systems.
  • Suitable for species that have the ability to produce multiple stems but can be managed as single-stem coppice, such as sweet chestnut.

5. Continuous cover coppice:

  • Aims to maintain a continuous cover of trees or shrubs by selectively cutting individual stems or groups of stems.
  • Allows for a more diverse and uneven-aged forest structure compared to traditional coppice systems.
  • Suitable for species that can tolerate partial shade and have the ability to resprout, such as beech and hornbeam.

6. Pollarding:

  • Similar to coppicing, but involves cutting the tree or shrub above the ground level, typically at a higher level than stool coppicing.
  • Allows for the production of larger diameter stems and longer rotation periods compared to coppice regeneration.
  • Commonly used for species like willow, poplar, and mulberry.

7. Short rotation coppice:

  • Involves growing fast-growing tree species, such as willow or poplar, in a short rotation period (typically 2-5 years) for biomass production.
  • The trees are cut back to the ground level after each rotation to stimulate vigorous regrowth.
  • Used for bioenergy production or as a source of raw material for various industries.

Coppicing Cycle

A. Determining the cycle length in Coppice System in Silviculture:

1. Species characteristics:

  • Different tree species have varying growth rates and regeneration abilities.
  • Some species may require longer or shorter cycle lengths based on their growth patterns and ability to resprout after cutting.

2. Site conditions:

  • The site's soil fertility, moisture availability, and other environmental factors can influence the growth rate and regeneration potential of tree species.
  • Sites with favorable conditions may allow for shorter cycle lengths, while less productive sites may require longer cycles.

3. Desired products:

  • The intended use of the harvested wood products can influence the cycle length.
  • If the primary goal is to produce small-diameter wood for fuel or pulp, shorter cycle lengths may be preferred.
  • For larger timber or specialty wood products, longer cycle lengths may be necessary to allow for sufficient growth and quality.

4. Market demand:

  • The demand for specific wood products can also impact the cycle length.
  • If there is a high demand for certain products, shorter cycle lengths may be necessary to meet market needs.
  • Conversely, if demand is low or fluctuating, longer cycle lengths may be more appropriate to avoid overproduction.

5. Management objectives:

  • The overall objectives of the forest management plan can influence the cycle length.
  • If the goal is to maximize timber production, shorter cycle lengths may be preferred to ensure a continuous supply of harvested wood.
  • However, if the focus is on biodiversity conservation or ecosystem services, longer cycle lengths may be necessary to allow for natural regeneration and habitat development.

6. Monitoring and adaptive management:

  • Regular monitoring of the coppice system's performance can help determine the appropriate cycle length.
  • By assessing the growth rates, regeneration success, and market conditions, adjustments can be made to optimize the cycle length over time.
  • Adaptive management approaches allow for flexibility in modifying the cycle length based on new information or changing circumstances.

B. Factors affecting cycle length in the coppice system in silviculture include:

1. Species characteristics:

  • Growth rate: Faster-growing species tend to have shorter cycle lengths as they can regenerate more quickly.
  • Sprouting ability: Species with a high sprouting ability can regenerate more effectively, allowing for shorter cycle lengths.
  • Tolerance to cutting: Some species can tolerate frequent cutting, enabling shorter cycle lengths.

2. Site conditions:

  • Soil fertility: Highly fertile soils can support faster growth and regeneration, leading to shorter cycle lengths.
  • Moisture availability: Adequate moisture levels are essential for growth and regeneration, influencing the length of the cycle.
  • Light availability: Sufficient light is necessary for photosynthesis and growth, affecting the speed of regeneration and cycle length.

3. Management objectives:

  • Timber production: If the primary objective is timber production, longer cycle lengths may be preferred to allow for larger tree sizes and higher wood quality.
  • Biomass production: For biomass production, shorter cycle lengths may be desired to maximize the yield of woody biomass.
  • Biodiversity conservation: Longer cycle lengths can promote biodiversity by providing more time for the development of understory vegetation and habitat for various species.

4. Market demand and economic considerations:

  • Market demand: The demand for specific products from coppice systems can influence the cycle length. If there is a high demand for certain products, shorter cycle lengths may be chosen to meet market needs.
  • Economic viability: The economic feasibility of managing coppice systems can impact the cycle length. Longer cycle lengths may be preferred if the costs of management and regeneration outweigh the potential benefits.

5. Environmental factors:

  • Climate: Climate conditions, such as temperature and precipitation patterns, can affect the growth and regeneration rates of coppice species, influencing the cycle length.
  • Pest and disease pressure: Higher pest and disease pressure can impact the health and vigor of coppice stands, potentially leading to longer cycle lengths to allow for recovery and regeneration.

6. Silvicultural practices:

  • Cutting intensity: The intensity of cutting, such as the percentage of trees removed, can influence the cycle length. Higher cutting intensities may require longer cycle lengths to allow for sufficient regeneration.
  • Cutting frequency: The frequency of cutting can affect the cycle length. More frequent cutting may result in shorter cycle lengths, while less frequent cutting may require longer cycles.

Silvicultural Practices in Coppice System

1. Regeneration:

  • Clearcutting: The entire stand is harvested at once, allowing for the regeneration of new shoots from the stumps.
  • Shelterwood cutting: A two or three-stage process where mature trees are removed in a series of cuts, providing partial shade and protection for the regeneration.

2. Coppicing:

  • Cutting back: The stems of the harvested trees are cut back to ground level, stimulating the growth of new shoots from the stump.
  • Rotation period: The time interval between successive coppicing cycles, which can vary depending on the species and management objectives.

3. Thinning:

  • Selective cutting: Removing some of the competing or undesirable stems to improve the growth and quality of the remaining trees.
  • Crown thinning: Removing branches or stems from the upper canopy to allow more light penetration and promote the growth of understory vegetation.

4. Soil and site preparation:

  • Site selection: Choosing suitable sites with appropriate soil conditions, drainage, and exposure for the coppice system.

Environmental and Ecological Considerations

Environmental Considerations:

  • Biodiversity conservation: Coppice systems can promote biodiversity by creating a diverse range of habitats for different plant and animal species. The regrowth of coppiced trees provides opportunities for various species to thrive, including understory plants, insects, birds, and mammals.
  • Soil conservation: Coppicing can help prevent soil erosion by maintaining a continuous cover of vegetation. The regrowth of coppiced trees also contributes to the accumulation of organic matter, improving soil fertility and structure.
  • Water management: Coppice systems can have positive effects on water management. The dense regrowth of coppiced trees can help reduce water runoff and increase water infiltration, thus minimizing the risk of flooding and improving water quality.
  • Carbon sequestration: Coppice systems can contribute to carbon sequestration as the regrowth of coppiced trees absorbs carbon dioxide from the atmosphere. This can help mitigate climate change by reducing greenhouse gas emissions.

Ecological Considerations:

  • Succession and habitat dynamics: Coppice systems mimic natural disturbance regimes, promoting ecological succession and creating a mosaic of different successional stages. This allows for the development of diverse habitats and supports a wide range of species with varying habitat requirements.
  • Wildlife habitat: Coppice systems provide valuable habitat for many wildlife species. The regrowth of coppiced trees offers nesting sites, food sources, and cover for birds, mammals, and insects. The diverse structure of coppice stands can support a higher abundance and diversity of wildlife compared to unmanaged forests.
  • Nutrient cycling: Coppicing enhances nutrient cycling by promoting the decomposition of organic matter and the release of nutrients back into the soil. This can improve nutrient availability for both the regrowth of coppiced trees and other plants in the ecosystem.
  • Genetic diversity: Coppice systems can help maintain genetic diversity within tree populations. By allowing multiple stems to regrow from the stump, coppicing preserves a wide range of genetic traits, increasing the resilience of the population to environmental changes and potential threats such as pests and diseases.
  • Landscape aesthetics: Coppice systems can enhance the aesthetic value of landscapes by creating visually appealing and diverse woodland structures. The presence of different successional stages and the regrowth of coppiced trees can provide a more dynamic and visually interesting landscape compared to uniform, unmanaged forests.

Advantages of Coppice Systems

1. Increased productivity:

  • Coppice systems allow for multiple harvests from the same area over time, resulting in higher overall productivity compared to single rotation systems.
  • The regrowth from the cut stumps grows rapidly, leading to a quicker turnover of biomass and subsequent harvests.

2. Cost-effective:

  • Coppice systems require less initial investment compared to other silvicultural systems as they utilize existing root systems and stumps for regrowth.
  • The reduced need for replanting and site preparation contributes to lower overall costs.

3. Sustainable utilization of resources:

  • Coppice systems promote sustainable utilization of forest resources by utilizing the regrowth from previously harvested trees.
  • By selectively cutting only certain trees or sections of the stand, the remaining trees can continue to grow and provide habitat for wildlife.

4. Diverse habitat creation:

  • Coppice systems create a diverse range of habitats due to the varying stages of growth and different tree species present in the regrowth.
  • This diversity supports a wide range of plant and animal species, contributing to overall biodiversity conservation.

5. Increased carbon sequestration:

  • The rapid regrowth of coppiced trees leads to increased carbon sequestration, helping to mitigate climate change.
  • The repeated cutting and regrowth cycles allow for continuous carbon uptake and storage in the forest ecosystem.

6. Enhanced landscape aesthetics:

  • Coppice systems can contribute to the aesthetic appeal of the landscape, particularly in areas where traditional management practices are valued.
  • The presence of regenerating trees and the visual diversity of different growth stages can create a visually appealing and dynamic forest landscape.
  • 7. Local community benefits:
  • Coppice systems can provide opportunities for local communities to engage in sustainable forest management and generate income through the sale of coppice products.
  • The availability of coppice wood for fuel, construction, and other purposes can also contribute to local self-sufficiency and reduce dependence on external resources.

Disadvantages of Coppice Systems

  • Reduced timber quality: Coppice systems often result in the production of smaller diameter and lower quality timber compared to traditional forest management practices. This is because the trees are cut at a young age, leading to the formation of multiple stems that compete for resources and grow rapidly, resulting in weaker and less valuable wood.
  • Increased risk of disease and pests: The regrowth of coppiced trees is more susceptible to diseases and pests due to the increased density and proximity of the stems. This can lead to higher mortality rates and reduced overall productivity of the coppice stand.
  • Limited species diversity: Coppice systems tend to favor a few dominant tree species that are well-adapted to resprouting. This can lead to a reduction in overall species diversity within the forest, as other less competitive species may be outcompeted and eventually disappear from the stand.
  • Soil degradation: Repeated cutting and regrowth cycles in coppice systems can result in soil degradation over time. The removal of aboveground biomass during harvesting reduces the organic matter content in the soil, leading to decreased fertility and nutrient availability. Additionally, the repeated disturbance of the soil during harvesting operations can cause erosion and compaction.
  • Reduced wildlife habitat: Coppice systems often provide less suitable habitat for certain wildlife species compared to mature forests. The dense regrowth and lack of large trees and deadwood can limit the availability of nesting sites, food sources, and shelter for various wildlife species, particularly those that rely on specific forest structures.
  • Increased management requirements: Coppice systems require regular monitoring and management interventions to ensure proper regeneration and control the growth of competing vegetation. This can be labour-intensive and costly, especially in large-scale operations, making it less feasible for some forest owners or managers.
  • Limited economic value: The lower quality and smaller size of coppiced timber can result in reduced economic value compared to timber from mature forests. This can make it less financially viable for commercial timber production, particularly in areas where alternative sources of timber are available.
  • Lack of aesthetic appeal: Coppice systems often lack the aesthetic appeal of mature forests, as they typically consist of dense and uniform stands of young trees. This can impact recreational and tourism values associated with forests, potentially reducing their attractiveness to visitors and local communities.

  • These regulations may include guidelines on the minimum and maximum rotation periods, cutting techniques, and sustainable harvesting practices.
  • The legal framework ensures that coppice systems are managed in an environmentally responsible and sustainable manner.

2. Sustainable Harvesting:

  • Best practices in coppice system management emphasize sustainable harvesting techniques.
  • This involves selectively cutting only a portion of the coppice shoots, allowing the remaining shoots to regenerate and continue the growth cycle.
  • Sustainable harvesting ensures the long-term productivity and health of the coppice stand.

3. Rotation Period:

  • The rotation period refers to the time interval between successive coppice harvests.
  • Best practices recommend determining an optimal rotation period based on the species, site conditions, and desired products.
  • Longer rotation periods allow for greater biomass accumulation and potentially higher-quality wood, while shorter rotation periods may be suitable for certain fast-growing species.

4. Cutting Techniques:

  • Proper cutting techniques are crucial for the successful regeneration and growth of coppice stands.
  • Best practices suggest using clean and precise cutting tools to minimize damage to the remaining shoots and promote healthy regrowth.
  • Cutting at the appropriate height and angle helps stimulate vigorous shoot development.

5. Regeneration Methods:

  • Various regeneration methods can be employed in coppice systems, including natural regeneration and artificial regeneration.
  • Natural regeneration relies on the existing seed bank or the sprouting ability of the root system to regenerate new shoots.
  • Artificial regeneration involves planting seedlings or propagating cuttings to establish new coppice stands.

6. Monitoring and Assessment:

  • Regular monitoring and assessment of coppice stands are essential to ensure their health and productivity.
  • Best practices recommend periodic assessments of growth rates, stand density, and overall stand condition.
  • Monitoring helps identify any issues or disturbances that may require intervention, such as pest outbreaks or disease infestations.

7. Biodiversity Conservation:

  • Coppice systems can contribute to biodiversity conservation by providing habitat for various plant and animal species.
  • Best practices emphasize the importance of maintaining a diverse range of tree species and age classes within coppice stands.
  • This promotes ecological resilience and supports a wide array of wildlife and plant communities.

8. Stakeholder Engagement:

  • Effective stakeholder engagement is crucial for the successful implementation of coppice systems in silviculture.
  • Best practices encourage involving local communities, forest owners, and relevant stakeholders in decision-making processes.
  • Engaging stakeholders helps ensure that the management of coppice systems aligns with local needs, cultural values, and sustainable development goals.

Conclusion

The coppice system in silviculture offers numerous benefits, including increased productivity, sustainable utilization of forest resources, and diverse habitat creation. Effective management techniques, such as appropriate cutting cycles and regeneration methods, are crucial for maintaining the health and productivity of coppice stands. However, it is important to consider potential drawbacks, such as reduced timber quality and limited species diversity, when implementing the coppice system. Overall, the coppice system remains a valuable and versatile approach to forest management, particularly for the production of wood fuel and small-diameter timber products.
