Widowmaker (forestry)
In forestry, a widowmaker or fool killer is a detached or broken limb or tree top. The name indicates that such objects can kill forest workers by falling on them, thus "making widows" of their spouses. The U.S. Occupational Safety and Health Administration describes widowmakers as "broken off limbs that are hanging freely in the tree to be felled or in the trees close by." Etymology The phrase "widow maker" was first applied to eucalyptus trees by early European settlers logging in Australia. If a limb or tree top fell on a logger, their spouse a widowed. The logging industry was exclusively male at the time, hence why the phrase became "widow maker" instead of "widower maker". Causes Widowmakers are often caused by fungal growth over a sustained period. They can also occur with age, as old trees will carry dead wood in their canopies. While this dead wood is usually sturdy enough to not fall on its own, a storm or heavy wind can cause it to fall. Other causes include damage f ...

Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests and woodlands for associated resources for human and Natural environment, environmental benefits. Forestry is practiced in plantations and natural Stand level modelling, 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 resources, water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as "Carbon dioxide sink, sinks" for Earth's atmosp ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Occupational Safety And Health Administration
The Occupational Safety and Health Administration (OSHA; ) is a regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act (OSH Act), which President Richard Nixon, Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance." The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival. History The Bureau of Labor Standards of the Department of Labor has worked on some work safety issues since its creation in 1934. Economi ...

Grit (newspaper)
''Grit'' is a magazine, formerly a weekly newspaper, popular in the rural America, rural U.S. during much of the 20th century. It carried the subtitle "America's Greatest Family Newspaper". In the early 1930s, it targeted small town and rural families with 14 pages plus a fiction supplement. By 1932, it had a circulation of 425,000 in 48 states, and 83% of its circulation was in towns of fewer than 10,000 inhabitants. History The publication was founded in 1882 as the Saturday edition of the Williamsport, Pennsylvania, Williamsport, Pennsylvania, ''Daily Sun and Banner''. In 1885, the name was purchased for $1,000 by 25-year-old German immigrant Dietrick Lamade (pronounced Lam'-a-dee), who established a circulation of 4,000 during the first year. Lamade was born February 6, 1859, in Bretten, Gölshausen, Baden-Württemberg, Southern Germany, one of nine children of Johannes Dietrick and Caroline Stuepfle Lamade.

Chainsaw
A chainsaw (or chain saw) is a portable handheld power saw, power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, Log bucking, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of Wood fuel#Firewood, firewood, for use in Chainsaw carving, chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century. A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. History In surgery A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (–1785) by two Scot ...

Snag (ecology)
In forest ecology, a snag is a standing dead or dying tree, often missing a top or most of the smaller branches. In freshwater ecology the term ''snag'' refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris. Snags provide habitat for a wide variety of wildlife but pose hazards to river navigation. When used in manufacturing, especially in Scandinavia, they are often called dead wood and in Finland, kelo wood. Forest snags Snags are an important structural component in forest communities, making up 10–20% of all trees present in old-growth tropical, temperate, and boreal forests. Snags and downed coarse woody debris represent a large portion of the woody biomass in a healthy forest. In temperate forests, snags provide critical habitat for more than 100 species of bird and mammal, and snags are often called 'wildlife trees' by foresters. Dead, decaying wood supports a rich comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
