Protection Forest
Protection forests are forests that mitigate or prevent the impact of a natural hazard, including a rockfall, avalanche, erosion, landslide, debris flow or flooding on people and their assets in mountainous areas. A protection forest generally covers the sloping area between a hazard potential (e.g. an unstable rock cliff or an avalanche release zone) and the endangered or exposed assets. In the Alps, protection forests are increasingly considered equal to engineered mitigation measures against natural hazards. In French, German, Italian and Slovenian protection forests are called respectively, ''ForĂȘt de protection'', ''Schutzwald'', ''foreste di protezione'', ''varovalni gozdovi'', and even their maintain function is to protect soil and to prevent it from eroding or blowing away. Austrian law The Austrian law makes it clear the difference between a protection forest ''Schutzwald'' and a protected forest Bannwald. In this case it can be seen that a protection forest is larg ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

Windthrow
In forestry, windthrow refers to trees uprooted by wind. Breakage of the tree bole (botany), bole (trunk) instead of uprooting is called windsnap. Blowdown refers to both windthrow and windsnap. Causes Windthrow is common in all forested parts of the world that experience storms or high wind speeds. The risk of windthrow to a tree is related to the tree's size (height and diameter), the 'sail area' presented by its crown, the anchorage provided by its roots, its exposure to the wind, and the local wind climate. A common way of quantifying the risk of windthrow to a forest area is to model the probability or 'return time' of a wind speed that would damage those trees at that location. Another potential method is the detection of scattered windthrow based on satellite images. Tree senescence can also be a factor, where multiple factors contributing to the declining health of a tree reduce its anchorage and therefore increase its susceptibility to windthrow. The resulting dama ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Forest Protection
Forest protection is a branch of forestry which is concerned with the preservation or improvement of a forest and prevention and control of damage to forest by natural or man made causes like forest fires, plant pests, and adverse climatic conditions (global warming). Forest protection also has a legal status and rather than protection from only people damaging the forests is seen to be broader and include forest pathology too. Due to the different emphases there exist widely different methods forest protection. In German-speaking countries, forest protection would focus on the biotic and abiotic factors that are non-crime related. A protected forest is not the same as a protection forest. These terms can lead to some confusion in English, although they are clearer in other languages. As a result, reading English literature can be problematic for non-experts due to localization and conflation of meanings. The types of man-induced abuse that forest protection seeks to preven ...

Protected Forest
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, funga, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals d ...

Water Transportation
Water transportation is the international movement of water over large distances. Methods of transportation fall into three categories: * Aqueducts, which include pipelines, canals, tunnels and bridges A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually somet ... * Container shipment, which includes transport by tank truck, tank car, and tanker (ship), tank ship. * Towing, where a tugboat is used to pull an iceberg or a Flexible barge, large water bag along behind it. Due to its weight, the transportation of water is very energy-intensive. Unless it has the assistance of gravity, a canal or long-distance pipeline will need pumping stations at regular intervals. In this regard, the lower friction levels of the canal make it a more economical solution than the pipeline. Water transportation ...

Holy Spring
A holy well or sacred spring is a well, spring or small pool of water revered either in a Christian or pagan context, sometimes both. The water of holy wells is often thought to have healing qualities, through the numinous presence of its guardian spirit or Christian saint. They often have local legends associated with them; for example in Christian legends, the water is often said to have been made to flow by the action of a saint. Holy wells are often also places of ritual and pilgrimage, where people pray and leave votive offerings. In Celtic regions, strips of cloth are often tied to trees at holy wells, known as clootie wells. Names The term ''haeligewielle'' is in origin an Anglo-Saxon toponym attached to specific springs in the landscape; its current use has arisen through folklore scholars, antiquarians, and other writers generalising from those actual 'Holy Wells', which survived into the modern era. The term 'holy-hole' is sometimes employed.A. Ross, ''Pagan Celtic B ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Snowdrift
A snowdrift is a deposit of snow sculpted by wind into a mound during a snowstorm. Snowdrifts resemble sand dunes and are formed in a similar manner, namely, by wind moving light snow and depositing it when the wind has virtually stopped, usually against a stationary object. Snow normally crests and slopes off toward the surface on the windward side of a large object. On the leeward side, areas near the object are a bit lower than surrounding areas but are generally flatter. The impact of snowdrifts on transportation can be more significant than the snowfall itself, such as in the US during the Great Blizzard of 1978. Snowdrifts are usually found at or on roads, as the crest of the roadbed or the Furrow (other), furrows along the road create the disruption to the wind needed to shed its carried snow. Snow fences may be employed on the windward side of the road to intentionally create a drift before the snow-laden wind reaches the road. Photo gallery File:Long Mynd s ...

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 forest 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, GIS and photogrammetry modelling 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 appli ...
