CHAPTER-6.    NATURAL VEGETATION & WILDLIFE

VEGETATION

        Forest

        Grassland

        Shrubs

FACTORS AFFECTING VEGETATION

        Varies with height

        Temperature

        Moisture

        Slope

        Soil Thickness

CATEGORIES OF VEGETATION

        Forest- Region of plenty of rain and temperature

        Grass lands- Moderate Rain

        Shrubs- Dry Region

 

TROPICAL EVERGREEN FOREST

        Also called Tropical Rainforest

        From equator to tropic

        Hot and humid

        Rain throughout the year

        Sunlight don’t penetrate down

        Rosewood, mahogany, ebony

 

TROPICAL DECIDUOUS FOREST

        Monsoon forest in India

        North Australia

        Central America

        Have Seasonal changes

        Trees shed leaves in dry months to conserve water

        Sal, teak, neem, shisham- furnitures

        Tiger, lions, elephants, monkeys

 

TEMPERATE EVERGREEN FOREST

        Mid latitudinal coastal areas

        East margin of SE USA, S. China and SE Brazil

        Oak, pine, eucalyptus

 

TEMPERATE DECIDUOUS FOREST

        At higher latitudes

        NE USA, China, Newzeland, Chile, W.Europe

        Shed leaves in dry season

        Deer, fox, wolf, pheasants, and monals

 

 

MEDITERRANEAN VEGETATION

        East and NE margins of temperate and deciduous forests

        Mediterranean Sea region, California, SW Africa, SW Australia and S. America

        Hot dry summer-thick bark and wax coated leaves- reduce transpiration

        Mild rainy winters

        Orchards of the world

        Oranges, figs, olives, grapes

 

CONIFEROUS FORESTS

        All higher latitude (50-70 degree) North and South

        Taiga (pure in Russian) – untouched

        Tall, softwood evergreen – pulp, paper, match box, packaging

        Chir, pine, cidar

 

TROPICAL GRASSLANDS

        Either side of equator

        Low to moderate rain

        Tall up to 3 to 4 meters

        East Africa- Savannas

        Venezuela- Lianos

        Elephant, Zebra, Leopard, Deer, Giraffe

 

TEMPERATE GRASSLANDS

        Mid-latitude and interior of continent

        Short and nutritious grass

        Wild Buffalo, Bison, Antelope

        Argentina- Pampas

        North America- Prairies

        South Africa- Velds

        Central Asia- Steppe

        Australia- Downs
