Class 7. Psammophytes (of formations on sand and gravel). Class 8. Chersophytes (of formations on waste land). 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.
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 ...
Mangrove vegetation is characteristic of estuarine tracts along the coast for instance, at Ratnagiri in Maharashtra. Larger parts of the coastal plains are covered by fertile soils on which different crops are grown. Rice is the main crop of these areas. Coconut trees grow all along the coast. Coconut and rubber are the main vegetation of ...
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]
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.
