Forest management


Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as [|silviculture], [|forest protection], and regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values. Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, [|planting] and [|replanting] of different species, building and maintenance of roads and pathways through forests, and preventing [|fire].
Many tools like remote sensing, geographic information systems, and photogrammetry have been developed to improve forest inventory and management planning. Scientific research plays a crucial role in helping forest management. For example, climate modeling, biodiversity research, carbon sequestration research, GIS applications, and long-term monitoring help assess and improve forest management, ensuring its effectiveness and success.

Role of forests

The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods. The working of a forest is influenced by the natural environment: climate, topography, soil, etc., and also by human activity. The actions of humans in forests constitute forest management.

Aims

Some forests have been and are managed to obtain traditional forest products such as firewood, fiber for paper, and timber, with little thinking for other products and services. Nevertheless, as a result of the progression of environmental awareness, management of forests for multiple use is becoming more common.
Forests provide a variety of ecosystem services: cleaning the air, accumulating carbon, filtering water, and reducing flooding and erosion. Forests are the most biodiverse land-based ecosystem, and provide habitat for a vast array of animals, birds, plants and other life. They can provide food and material and also opportunities for recreation and education. Research has found that forest plantations "may result in reduced diversity and abundance of pollinators compared with natural forests that have greater structural and plant species diversity."

Monitoring and planning

Foresters develop and implement forest management plans relying on mapped resources, inventories showing an area's topographical features as well as its distribution of trees and other plant covers. Plans also include landowner objectives, roads, culverts, proximity to human habitation, water features and hydrological conditions, and soil information. Forest management plans typically include recommended silvicultural treatments and a timetable for their implementation. Application of digital maps in Geographic Information systems that extracts and integrates different information about forest terrains, soil type and tree covers, etc. using, e.g. laser scanning enhances forest management plans in modern systems.
Forest management plans include recommendations to achieve the landowner's objectives and desired future conditions for the property subject to ecological, financial, logistical, and other constraints. On some properties, plans focus on producing quality wood products for processing or sale. Hence, tree species, quantity, and form, all central to the value of harvested products quality and quantity, tend to be important components of silvicultural plans.
Good management plans include consideration of future conditions of the stand after any recommended harvests treatments, including future treatments, and plans for natural or artificial regeneration after final harvests.
The objectives of landowners and leaseholders influence plans for harvest and subsequent site treatment. In Britain, plans featuring "good forestry practice" must always consider the needs of other stakeholders such as nearby communities or rural residents living within or adjacent to woodland areas. Foresters consider tree felling and environmental legislation when developing plans. Plans instruct the sustainable harvesting and replacement of trees. They indicate whether road building or other forest engineering operations are required.
Agriculture and forest leaders are also trying to understand how the climate change legislation will affect what they do. The information gathered will provide the data that will determine the role of agriculture and forestry in a new climate change regulatory system.

Forest inventory

Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems.

Wildlife considerations

The abundance and diversity of birds, mammals, amphibians and other wildlife are affected by strategies and types of forest management. Forests are important because they provide these species with food, space and water. Forest management is also important as it helps in conservation and utilization of the forest resources.Forest clearing to aid specific species of wildlife has been criticized because it can fragment forests leading to deleterious effects.
Approximately 50 million hectares of European forest land is protected for biodiversity and landscape protection. Forests allocated for soil, water, and other ecosystem services encompass around 72 million hectares. Over 90% of the world's forests regenerate organically, and more than half are covered by forest management plans or equivalents.

Management intensity

Forest management varies in intensity from a leave alone, natural situation to a highly intensive regime with silvicultural interventions. Forest Management is generally increased in intensity to achieve either economic criteria or ecological criteria.
Most of the forests in Europe have management plans; on the other hand, management plans exist for less than 25 percent of forests in Africa and less than 20 percent in South America. The area of forest under management plans is increasing in all regions – globally, it has increased by 233 million ha since 2000, reaching 2.05 billion ha in 2020.

Monitoring

Long-term monitoring studies are conducted to track forest dynamics over extended periods. These studies involve monitoring factors such as tree growth, mortality rates, and species composition. By observing forest changes over time, scientists can assess the health of forests and their responses to environmental shifts. Long-term monitoring is invaluable for informing sustainable forest management practices. Yet such monitoring is usually of the type that provide "early warning" only, while a more valuable approach would be to combine long-term monitoring and long-term experiments, thereby revealing causality
Scientific research employs remote sensing technologies and geographic information systems to monitor changes in forest cover, deforestation rates, and forest health over time. These tools provide valuable data for forest assessments and support evidence-based decision making in forest management and conservation. By remotely monitoring forest changes, scientists can respond more effectively to threats and challenges facing forests.
Researchers conduct biodiversity assessments to gain insights into the diversity and distribution of plant and animal species in various forest ecosystems. These studies are essential for identifying areas of high conservation value and understanding the ecological importance of different habitats. By studying biodiversity patterns, scientists can recommend targeted approaches to forest management that protect and promote the richness of forest life.

Effects of climate change on forests

Research explores the specific impacts of climate change on forest ecosystems, including extreme heat and drought events. Understanding these effects is vital for developing adaptive strategies to mitigate climate change impacts on forests. By recognizing the vulnerabilities of forests to changing climatic conditions, scientists can implement conservation methods that enhance their resilience.
Scientific research plays a crucial role in forest management by utilizing climate modeling to project future climate scenarios. These models help scientists understand potential changes in temperature, precipitation patterns, and extreme weather events, enabling them to assess the impact of these changes on forest ecosystems. By predicting climate trends, researchers can develop more effective strategies for forest management and conservation.

Methods for creating or recreating forests

The term forestation is sometimes used as an umbrella term to include afforestation and reforestation. Both of those are processes for establishing and nurturing forests on lands that either previously had forest cover or were subjected to deforestation or degradation.

Hardwood timber production

Hardwood timber production is the process of managing stands of deciduous trees to maximize woody output. The production process is not linear because other factors must be considered, including marketable and non-marketable goods, financial benefits, management practices, and the environmental implications, of those management practices.
The more biodiverse the hardwood-forest ecosystem, the more challenges and opportunities its managers face. Managers aim for sustainable forest management to keep their cash crop renewing itself, using silvicultural practices that include growing, selling, controlling insects and most diseases, providing manure, applying herbicide treatments, and thinning.
But management can also harm the ecosystem; for example, machinery used in a timber harvest can compact the soil, stress the root system, reduce tree growth, lengthen the time needed for a stand to mature to harvestability. Machinery can also damage the understory, disturbing wildlife habitat and prevent regeneration.
