D. The climate is very dry and decides the character of the vegetation; the properties of the soil are dominated by climate; the formations are also xerophilous: Class 9. Eremophytes (of formations on desert and steppe). Class 10. Psilophytes (of formations on savannah). Class 11. Sclerophyllous formations (bush and forest). E.
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.
An example of a vegetation type defined at the level of class might be "Forest, canopy cover > 60%"; at the level of a formation as "Winter-rain, broad-leaved, evergreen, sclerophyllous, closed-canopy forest"; at the level of alliance as "Arbutus menziesii forest"; and at the level of association as "Arbutus menziesii-Lithocarpus dense flora ...

[7] Canada: Canadian National Vegetation Classification (CNVC) Full taxonomic vegetation 8-level hierarchy based on floristic, ecological, and physiognomic criteria. Based on 'associations' and 'alliances'. [8] [9]
The system has been shown to fit not just tropical vegetation zones, but Mediterranean zones, and boreal zones too, but is less applicable to cold oceanic or cold arid climates where moisture becomes the predominant factor. The system has found a major use in assessing the potential changes in natural vegetation patterns due to global warming. [3]
Indian Forest cover map as of 2015. Tropical evergreen forests of India are found in the Andaman and Nicobar Islands, [a] the Western Ghats, [b] which fringe the Arabian Sea, the coastline of peninsular India, and the greater Assam region in the north-east. [c] Small remnants of semi-evergreen forest are found in Odisha state.
Foliage and cone of the Aleppo pine (Pinus halepensis).. The natural vegetation consists of forests, woodlands, and shrublands.The five chief plant communities are: Xeric pine forests and woodlands: The xeric pine forests are found mainly in the drier interior, near the transition to the Mediterranean dry woodlands and steppe, where rainfall averages 300 to 600 mm per year.
Mapping of the distribution and extent of natural vegetation of South Africa started in 1918 when the Botanical Survey of the Union of South Africa was established. Maps by Pole-Evans (1936), Acocks (1953), and Low and Rebelo (1996) preceded the current system, which is the combined effort of participants from various centres in the country. [2]
