| Terms for subject Environment (5878 entries) |
| غابات المناطق المعتدلة | temperate forest (Mixed forest of conifers and broad-leaf deciduous trees, or mixed conifer and broad-leaf evergreen trees, or entirely broad-leaf deciduous, or entirely broad-leaf evergreen trees, found in temperate regions across the world; characterized by high rainfall, warm summers, cold winters occasionally subzero, seasonality; typically with dense canopies, understorey saplings and tall shrubs, large animals, carnivores dominant, very rich in bird species) | |
| غابة | forest (A vegetation community dominated by trees and other woody shrubs, growing close enough together that the tree tops touch or overlap, creating various degrees of shade on the forest floor. It may produce benefits such as timber, recreation, wildlife habitat, etc.) | |
| غابة أصلية | indigenous forest (Forests which are native to a given area) | |
| غابة استوائية | tropical forest (A vegetation class consisting of tall, close-growing trees, their columnar trunks more or less unbranched in the lower two-thirds, and forming a spreading and frequently flat crown; occurs in areas of high temperature and high rainfall) | |
| غابة بدائية - غابة أولية | primary forest (Forest which originally covered a region before changes in the environment brought about by people) | |
| غابة تديرها الدولة | state forest (Forest owned and managed by the State) | |
| غابة جبلية | mountain forest (An extensive area of woodland that is found at natural elevations usually higher than 2000 feet) | |
| غابة خاصة | private forest (No definition needed) | |
| غابة خصبة | timber forest (Forest whose trees are all in the adult stage and have reached the reproductive period) | |
| غابة صغيرة | wood (A dense growth of trees more extensive than a grove and smaller than a forest) | |
| غابة صنوبر | coniferous forest (A forest type characterized by cone-bearing, needle-leaved trees. They are generally, but not necessarily, evergreen and relatively shallow-rooted. Since they grow more rapidly than most broad-leaved trees, conifers are extensively planted as a source of softwood timber and pulp. They are tolerant of wide-ranging climatic conditions, of many different types of soil and of considerable differences in terrain. Thus, they are found from the polar latitudes to the tropics, on most types of soils (especially, thin acid soils) and from mountain summits to coastal environments) | |
| غابة طبيعية | natural forest (A forest area that has developed free from the influence of humans and remains largely unaffected by their activities. The natural forest may include, but is not necessarily equivalent to, an old-growth forest) | |
| غابة متجددة الأوراق | deciduous forest (The temperate forests comprised of trees that seasonally shed their leaves, located in the east of the USA, in Western Europe from the Alps to Scandinavia, and in the eastern Asia. The hardwood of these forests have been exploited since the 16th century. The trees of deciduous forests usually produce nuts and winged seeds) | |
| غابة محمية | forest reserve (Forest area set aside for the purpose of protecting certain fauna and flora, or both) | |
| غابة مختلطة | mixed woodland | |
| غابة مختلطة | mixed forest (A forest composed of several tree species) | |
| غابة مطيرة | rain forest (A forest of broad-leaved, mainly evergreen, trees found in continually moist climates in the tropics, subtropics, and some parts of the temperate zones) | |
| غابة مطيرة استوائية | tropical rain forest (The most valuable and the richest ecosystem on Earth. It plays a critical part in the Earth's life support systems and house 50%, and possibly as much as 90%, of all the species on Earth. It is a key storehouse of foods, oils and minerals, and a source of ingredients that make up a range of medical treatments. It also represents home and livelihood for many people. However, more than half of the rainforests have disappeared, chopped down for valuable tropical hardwoods, or cleared to provide areas for cattle grazing or human habitation. The forests play an important part in climate patterns, and deforestation is thought to be responsible for 18% of global warming. Furthermore, as they disappear there is also an albedo effect - a damaging increase in the sunlight reflected - which affects wind and rainfall patterns) | |
| غاز | gas (A substance that continues to occupy in a continuous manner the whole of the space in which it is placed, however large or small this place is mad, the temperature remaining constant) | |
| غاز احتراق | combustion gas (The exhaust gas from a combustion process. It may contain nitrogen oxides, carbon oxides, water vapour, sulfur oxides, particles and many chemical pollutants) |
