Dante Alighieri D M Black Robert Pogue H Biography & Facts

Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests and woodlands for associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management plays an essential role in the creation and modification of habitats and affects ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as "sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important component of the biosphere, and forestry has emerged as a vital applied science, craft, and technology. A practitioner of forestry is known as a forester. Another common term is silviculturist. Silviculture is narrower than forestry, being concerned only with forest plants, but is often used synonymously with forestry. All people depend upon forests and their biodiversity, some more than others. Forestry is an important economic segment in various industrial countries, as forests provide more than 86 million green jobs and support the livelihoods of many more people. For example, in Germany, forests cover nearly a third of the land area, wood is the most important renewable resource, and forestry supports more than a million jobs and about €181 billion of value to the German economy each year. Worldwide, an estimated 880 million people spend part of their time collecting fuelwood or producing charcoal, many of them women. Human populations tend to be low in areas of low-income countries with high forest cover and high forest biodiversity, but poverty rates in these areas tend to be high. Some 252 million people living in forests and savannahs have incomes of less than US$1.25 per day. Forestry in the 21st century Today a strong body of research exists regarding the management of forest ecosystems and the genetic improvement of tree species and varieties. Forestry studies also include the development of better methods for the planting, protecting, thinning, controlled burning, felling, extracting, and processing of timber. One of the applications of modern forestry is reforestation, in which trees are planted and tended in a given area. Trees provide numerous environmental, social and economic benefits for people. In many regions, the forest industry is of major ecological, economic, and social importance, with the United States producing more timber than any other country in the world. Third-party certification systems that provide independent verification of sound forest stewardship and sustainable forestry have become commonplace in many areas since the 1990s. These certification systems developed as a response to criticism of some forestry practices, particularly deforestation in less-developed regions along with concerns over resource management in the developed world. Sustainable forestry operations must also adhere to the International Labour Organization's 18 criteria on human and social rights. Gender equality, health and well-being and community consultation are examples of mentioned rights. In topographically severe forested terrain, proper forestry is important for the prevention or minimization of serious soil erosion or even landslides. In areas with a high potential for landslides, forests can stabilize soils and prevent property damage or loss, human injury, or loss of life. Global production of roundwood rose from 3.5 billion m³ in 2000 to 4 billion m³ in 2021. In 2021, wood fuel was the main product with a 49 percent share of the total (2 billion m³), followed by coniferous industrial roundwood with 30 percent (1.2 billion m³) and non-coniferous industrial roundwood with 21 percent (0.9 billion m³). Asia and the Americas are the two main producing regions, accounting for 29 and 28 percent of the total roundwood production, respectively; Africa and Europe have similar shares of 20–21 percent, while Oceania produces the remaining 2 percent. Many lower- and middle-income countries rely on wood for energy purposes (notably cooking). The largest producers are all in these income groups and have large populations with a high reliance on wood for energy: in 2021, India ranked first with 300 million m³ (15 percent of total production), followed by China with 156 million m3 and Brazil with 129 million m³ (8 percent and 7 percent of global production). Foresters Foresters work for the timber industry, government agencies, conservation groups, local authorities, urban parks boards, citizens' associations, and private landowners. The forestry profession includes a wide diversity of jobs, with educational requirements ranging from college bachelor's degrees to PhDs for highly specialized work. Industrial foresters plan forest regeneration starting with careful harvesting. Urban foresters manage trees in urban green spaces. Foresters work in tree nurseries growing seedlings for woodland creation or regeneration projects. Foresters improve tree genetics. Forest engineers develop new building systems. Professional foresters measure and model the growth of forests with tools like geographic information systems. Foresters may combat insect infestation, disease, forest and grassland wildfire, but increasingly allow these natural aspects of forest ecosystems to run their course when the likelihood of epidemics or risk of life or property are low. Increasingly, foresters participate in wildlife conservation planning and watershed protection. Foresters have been mainly concerned with timber management, especially reforestation, forests at prime conditions, and fire control. Forestry plans 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 (by species) 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 (GIS) 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 subjec....
