Forest Resource A term associated with forests and range including, without limitation, timber, water, wildlife, fisheries, recreation, botanical forest products, forage, and biological diversity.
Forest A land with tree crown cover of more than 10%, and area of more than 0.5 hectare (1 hector=10000 m*m) is treated as forest. (FAO-UN: Food and Agriculture organization)
Components of Forest : Biotic (living) Abiotic(non-living) Trees , herbs Land , Water Grass Sunlight Animals Air Birds Nutrients
Types of Forest (Location Based) 1. Tropical Forests: • Area bounded by 23.5 degree N and 23.5 degree S • Hot and Humid climate • Temperature: 20-25 C • Rainfall : Exceeding 200 cm (i) Low land tropical forests: > Rain falls almost daily (ii) Tropical clowd forests : > Higher Altitudes
Types of Forest (Location Based) 2. Temperate deciduous Forests: • Occuring between 30 to 60 latitudes • Temperature varying between -30 to +30 C • Soil is fertile • Rain : 75-150 cm throughout year (i) Deciduous forests: > Northern hemisphere (ii) Evergreen forests : >Southern hemisphere
Types of Forest (Location Based) 3. Coniferous Forests: • Called “taiga” • Northern hemisphere (50 to 60 N) • Low bio diversity • Snow form (40 to 100 cm) • Soil is thin , acidic (i) Grasslands: > Short period rain, more droughts (ii) Tundra : >Frozen, extreme cold
Type of Forest in India : Type of Forest States 1. Rain evergreen forest Western Ghats 2. Tropical wet evergreen forest Kerala , Assam 3. Tropical deciduous forest Gujarat, Rajasthan 4. Broad leaves deciduous forest Himalaya 5. Coniferous deciduous forest U.P, H.P , J & K 6. Mangrove forest coastal area
INDIAN SCENARIO: Forests Non forest (79.45%) Dence Forest(12.68%) Open Forest(7.87%)
INDIAN SCENARIO: Forests Unclassified Forest (17%) Protected Forest(28%) Reserved Forests(55%)

IMPORTANCE OF FOREST : Function 1.Protective functions: Protect against : flood, soil erosion, drought ,etc. 2. Productive functions: Produces: katha , pulp ,paper , bamboos,etc.
IMPORTANCE OF FOREST : Function 3. Regulative function: Regulates : Temperature,O2,CO2. 4. Accessory function: Helps in : aesthetics and habitats of flora & fauna.
IMPORTANCE OF FOREST : * Ecological Importance * Regulation of Global climate and temperatures: Reduction in Global warming Production of Oxygen Conservation of soil Important in a fertility of soil Control of water flow Habitats to Wildlife Absorption of noise Absorption of Air Pollution
IMPORTANCE OF FOREST : * Economical Importance * Timber Fuel food Raw material for wood based industries Bamboo Food Miscellaneous products
Deforestations : Before After
Deforestations : Deforestation refers to the long term or permanent loss of forest cover. 10% loss of canopy is considered as Deforestation.
Causes of Deforestations: Population explosion Shifting Cultivation Growing food demands Fire foods Raw material for wood based industries Infrastructure Development Forest Fires : (i) Ground fire (ii) Surface fire (iii) Crown fire (iv) human activities Over grazing : Mining activities Attack of insects Natural forces
Effects of Deforestations: Destruction of species habitats Extinction of species Loss of Bio-diversity Reduction of vegetation Soil erosion Loss of soil fertility Loss of mineral nutrients Landslides Destructs Oxygen cycle Pollution + Global warming Less forest products Quality of our life
Forest Degradation in India : Before 20th century : 30% of land was covered by forest After 20th century : Only 19.4% is covered, Nothing like Tropical, All reduced to coastal NFC(1988) recommends 33% plain land forest , but we cover only 20% “Chipko” movements only because of massive destruction in U.P The Deforestation rate per unit population in india is lowest among the major tropical country.
Afforestation: Before : After:
Afforestations : The conservation measure against the deforestation is Afforestation. The development of forest by planting trees on waste land is called afforestation.
Afforestations : *Objectives* • To control deforestation • To prevent soil erosion • To regulate rainfall & temperature • To protect ecosystem
Afforestations : *Dam buildings* • Sardar Sarovar Project, Gujarat • Narmad Sagar Projects,M.P • Bhodgath Project on indravati river, M.P • Tehri dam on Bhagirathi river, Uttrakhand.
GTU Questions 1. Enlist all the Factors leading to deforestation? What are the effects and remedies for that? 2. Write a short note on : Afforestation 3. Distinguish between afforestation and deforestation. 4. Explain Tropical forests ?
