Tidal Forests

 Indian Natural Vegetation

 Littoral or Tidal Forests

(a) Climatic Conditions: These forests are found in wet marshy areas, in river deltas, in tidal or other swampy areas and along the sea coasts.

(b) Distribution:  These forests are chiefly distributed in the deltas of large rivers on the eastern coasts and in pockets on the western coast in saline swamps of Sunderbans in West Bengal and coastal areas of Andhra Pradesh and Odisha.

(c) Characteristic Features:
    i> They are mainly evergreen species of varying density and height, usually associated with wetness.
    ii> The tree trunks are supported by a number of stilt like roots which remain submerged
under water during high tide and can be seen during low tide.
    iv> These forests have breathing roots called pneumatophores. Because of waterlogged conditions, the roots are deprived of oxygen during high tides. So, some mangrove roots extends vertically above the ground. These vertical roots have pores which enable the trees to breathe when other roots remain submerged under water during high tide.

The important trees include keora, amur, bhara, rhizophora, screw pines, canes and palms, sundari, agar, etc. Mangrove forests grow along in the coast in the salts marshes, tidal creeks, mud flats and estuaries. They are found in the Andaman and Nicobar Islands and West Bengal.. Other areas of significance include the Mahanadi, the godavari and the Krishna deltas.

These forests have Sundari trees, after the name of which these forests are known as "Sunderbans" in the Ganga delta.

(d) Economical Value: Mangrove trees are utilised for fuel whereas sundari trees provide hard durable timber.

Indian Natural Vegetation | Geography of India

           Natural Vegetation Natural Vegetation  refers to the plant cover that has not been distributed over a long time, so as to allow its individual species to adjust themselves fully to the climate and soil conditions. Thus, grasses, shrubs and trees, which grow on their own without any human interference, constitute the natural vegetation of an area. [1]      There is difference between flora, vegetation and forest.  Flora  refers to plants of a particular region or period, listed as species and considered as a group. For example, the Eastern Himalayas have about 4000 species of plants which vary with  increasing altitude from tropical to temperate and alpine. [2]      Vegetation , on the other hand,  refers to the assemblage of plants   species living in association with each other in a given environmental setup. For example, the redwood forests, coastal mangroves, roadside weed patches, cultivated gardens and lawns, etc., all are encompassed by the term vegetation.

       Artificial Intelligence (A.I) Real incident related to A.I. Did you know, the year 2017, was one of the most dangerous years as an experiment of facebook created panic in the month of july-august. Yes! I am talking about the same facebook which you use almost everyday. Actually what happened was that those people were engaged in making an advanced chatbot. There are chatbot which  you also use, the message you send and automatic response comes through a program, that is called chatbot. Actually you chat with a robot who chats with hi-hello, just like humans. So they were engaged in making such chatbot which not only hi-hello, but also laugh, cry, angry, feel sad, in human way and talks in human voice. During same experiment, a very intelligent engineer of facebook got an idea in mind that lets make two chatbot and make them talk to each other instead of humans. He named the both two, bob and alice. And in a very surprising way they both started talking to each other.
