CHAPTER NATURAL VEGETATION H ave you ever been to a forest for a picnic? You might have surely gone to a park if you live in a city or to a mango‚ guava or coconut orchard‚ if you live in a village. How do you differentiate between the natural vegetation and the planted vegetation? The same variety may be found growing wild in the forest under natural conditions and the same tree may be the planted one in your garden under human supervision. Natural vegetation refers to a plant community

The following are the principal types of natural vegetation in India: (1) Tropical Evergreen Rain Forests‚ (2) Deciduous or Monsoon Type of Forests‚ (3) Dry Deciduous Forests and Scrubs‚ (4) Semi- Desert and Desert Vegetations‚ (5) Tidal or Mangrove Forests and (6) Mountain Forests. • Tropical evergreen rain forests: These forests grow in areas where rainfall is more than 200 cm. They are mainly found on the slopes of the Western Ghats and the Northeastern regions of Arunachal Pradesh‚ Meghalaya

Taiga Taiga (Boreal forest) - The boreal forest or taiga exists as a nearly continuous belt of coniferous trees across North America and Eurasia. Overlying formerly glaciated areas and areas of patchy permafrost on both continents‚ the forest is mosaic of successional and subclimax plant communities sensitive to varying environmental conditions. Taiga is the Russian name for this forest which covers so much of that country. However‚ the term is used in North America as well. Climate: The

Mediterranean Scrub Introduction: Regions of Mediterranean-type climate occur roughly between 30° and 40° latitude on the west coasts of continents‚ where offshore there are cold ocean currents. Each region in which the Mediterranean shrublands and woodlands occur is island-like in character and thus there is frequently a high degree of endemism. Comparative studies of the several regional expressions of this biome reveal interesting examples of convergent evolution in plant families and birds (but

Mixed forests are vegetational transition between coniferous forests and broad leaved deciduous forests. Common trees are ash‚ hemlock‚ oak‚ birch‚ maple‚ pine‚ fir‚ spruce‚ and cedar can be found in the mixed forest. Natural Vegetation brings up plants and tree growth without any human interference. Brampton is not really a natural vegetation whatsoever

TERRESTRIAL BIOME Introduction Many places on Earth share similar climatic conditions despite being found in geographically different areas. As a result of natural selection‚ comparable ecosystems have developed in these separated areas. Scientists call these major ecosystem types biomes. The geographical distribution (and productivity) of the various biomes is controlled primarily by the climatic variables precipitation and temperature. The maps in Figures 1 and 2 describe the geographical locations
