Content Global Distribution of Forest Forest Introduction Forest Types and their Distribution in India Importance of Forest Reference
Global distribution of forest Introduction Forests, refers to the collection of trees in an area which can be either natural or artificial Forest resources ,is the renewable natural resources which found in different parts of the world
Global distribution of forest According to the food agriculture organization(FAO)global forest resources assessment(2000)report, forest cover almost 1/3of the world land or 3869 million hectors This implies 95% is natural forest 5% is planted forest Forest are distributed unevenly across the globe two third of the world forest is currently distributed among 10 countries: Russian federation, Brazil ,Canada , USA , China , Australia ,Democratic republic of Congo , Indonesia & Peru
Distribution of forest by countries
Global distribution of forest : Unevenly distribution depends on the nature of the area which means - Climate Land (fertility or infertility) Cultural aspect over the geographical area
Global distribution of forest : The following are the types of forest and their distribution . Tropical rain forest Subtropical evergreen forest Mediterranean forest and scrubs Temperate forest Midlatitude deciduous forest
FOREST TYPE IN INDIA The detail classification and studies was done by CHAMPION and SETH into 16 categories of forest -
Temperature and range of rainfall in Tropical Rainforests Wet Evergreen- Temperature: 15-30C Rainfall-more than 200cm Semi Evergreen- Temperature:24-27C Rainfall-200-250cm Moist Deciduous-Temperature:27C Rainfall:100-200cm Littoral and Swamp-Temperature:26-29C Rainfall: 75-500cm Dry Deciduous-Temperature:10C Rainfall: 750-1500mm Thorn Forest-Temperature:25-30C Rainfall: Less than 70cm Dry Evergreen-Temperature: 28C Rainfall: 100cm
Montane subtropical forest Broad leaved hill forest ii. Pine forest iii. Dry evergreen
Montane wet temperate forest Wet temperate ii. Himalayan moist temperate iii. Himalayan dry temperate
Sub alpine forest i. Sub alpine forest
Alpine forest i. Moist alpine scrub ii. Dry alpine scrub
Importance of Forest Forests cover about a third of the earth's land area and are essential to the health of our environment . For example, trees and forests absorb and store much of the carbon dioxide that otherwise would be contributing to climate change. Forests are home to about 80 percent of remaining terrestrial biodiversity.
