Natural Vegetation And Wildlife Class 9 PDF
Have You Looked At The Many Kinds Of Trees, Shrubs, Grasses, And Birds In The Parks And Fields Near Your School? Do They Resemble One Another Or Do They Differ? Given The Size Of India, You Can Imagine The Range Of Bio-forms That Are Present There.
One Of The Top 12 Nations In The World For Biodiversity Is India. India Is Fourth In Asia And Tenth In The World For Plant Diversity, With Over 47,000 Plant Species. Approximately 15,000 Blooming Species, Or 6% Of All Flowering Plants Worldwide, May Be Found In India.
The Nation Is Home To Several Ferns, Algae, And Mushrooms, Among Other Non-flowering Plants. In Its Fresh And Saltwaters, India Is Home To More Than 90,000 Animal Species And A Wide Range Of Fish.
A Plant Community That Has Evolved Organically Through Time And Without Human Intervention Is Referred To As Natural Vegetation. We Refer To This As Virgin Vegetation. Thus, Orchards, Planted Fruits, And Other Types Of Vegetation Are Not Considered To Be Natural Vegetation.
Plants From A Certain Area Or Time Are Referred To As Flora. Animal Species Are Referred To Similarly As Fauna. The Following Elements Account For The Vast Variety Of The Flora And Animal Kingdom.
Both Directly And Indirectly, Land Has An Impact On Natural Vegetation. Do You Anticipate The Same Kind Of Vegetation In Dry And Rainy Locations As Well As In Hilly, Plateau, And Plain Areas? The Kind Of Vegetation Depends On The Land’s Characteristics. Agriculture Is Often Focused On The Fertile Level. Grassland And Forests Grow On The Undulating And Rocky Terrains, Providing Refuge For A Variety Of Species.
The Soils Differ Spatially As Well. Different Kinds Of Soils Serve As The Foundation For Various Plant Species. Cactus And Prickly Shrubs Grow On The Sandy Desert Soils, Whereas Mangroves And Other Deltaic Plants Grow On The Moist, Swampy Deltaic Soils. Conical Trees May Be Found On Hill Slopes With Considerable Depth Of Soil.
Temperature, Air Humidity, Precipitation, And Soil Moisture All Play Major Roles In Determining The Kind And Amount Of Vegetation. Above A Height Of 915 Metres, The Himalayan Slopes And The Hills Of The Peninsula Experience A Transition In Flora From Tropical To Subtropical Temperate And Alpine As A Result Of The Temperature.
Have You Ever Considered The Significance Of Woods To Humans? Forests Are A Significant Factor In Improving The Environment Since They Are A Renewable Resource. They Alter The Surrounding Temperature, Prevent Soil Erosion, Manage Stream Flow, Sustain A Wide Range Of Enterprises, Provide Numerous Populations A Means Of Subsistence, And Provide Panoramic Or Picturesque Views For Leisure.
They Influence Temperature And Wind, And They Can Bring Forth Rain. They Provide The Soil Humus And Shelter To The Animals. Due To A Number Of Circumstances, Including The Rise In Agricultural Demand, The Expansion Of Industries And Mining, Urbanisation, And Overgrazing Of Pastures, India’s Natural Vegetation Has Seen Significant Changes.
In Many Portions, India’s Vegetative Cover Is No Longer Really Natural. The Majority Of Areas’ Vegetation Has Been Altered, Replaced, Or Degraded By Human Habitation, With The Exception Of Certain Difficult Locations Like The Himalayas, The Hilly Region Of Central India, And The Marsthali.
These Forests Are Only Found In The Western Ghats’ High Rainfall Regions, As Well As The Island Groups Of Lakshadweep, Andaman, And Nicobar, The Higher Reaches Of Assam, And The Coast Of Tamil Nadu. They Do Best When There Is A Short Dry Season And More Than 200 Cm Of Rainfall Each Year.
The Trees Rise To Lofty Heights Of Up To 60 Metres Or More. The Area Has A Lush Vegetation Of All Types, Including Trees, Bushes, And Creepers, Giving It A Multilayered Structure Since It Is Warm And Humid Throughout The Year. Trees Don’t Always Lose Their Leaves At The Same Time Every Year. Because Of This, These Woods Seem Green All Year Round.
