Introduction on forest and wild life

  1. 1. FOREST AND WILDLIFE
  2. 2. FOREST • A FOREST IS USUALLY AN AREA FILLED WITH TREES BUT ANY TALL DENSELY PACKED AREA OF VEGETATION MAY BE CONSIDERED A FOREST • A FOREST, ALSO REFERRED TO A WOOD OR THE WOODS, IS AN AREA WITH A HIGH DENSITY OF TREES • TREE FORESTS COVER APPROXIMATELY 30 PERCENT OF TOTAL LAND AREA, THOUGH THEY ONCE COVERED MUCH MORE ABOUT 50 PERCENT OF TOTAL LAND AREA.
  3. 3. BIODIVERSITY • BIODIVERSITY IS THE DEGREE OF VARIATION OF LIFE FORMS WITHIN A GIVEN SPECIES, ECOSYSTEM OR BIOME. • "BIODIVERSITY" IS MOST COMMONLY USED TO REPLACE THE MORE CLEARLY DEFINED AND LONG ESTABLISHED TERMS, SPECIES DIVERSITY AND SPECIES RICHNESS. • BIOLOGISTS MOST OFTEN DEFINE BIODIVERSITY AS THE "TOTALITY OF GENES, SPECIES, AND ECOSYSTEMS OF A REGION". AN ADVANTAGE OF THIS DEFINITION IS THAT IT SEEMS TO DESCRIBE MOST CIRCUMSTANCES AND PRESENTS A UNIFIED VIEW OF THE TRADITIONAL THREE LEVELS AT WHICH BIOLOGICAL VARIETY HAS BEEN IDENTIFIED: SPECIES DIVERSITY ECOSYSTEM DIVERSITY GENETIC DIVERSITY
  4. 4. SPECIES • THE SPECIES ARE CLASSIFIED INTO SIX DIFFERENT SPECIES BASED ON IUCN THEY ARE: 1. NORMAL SPECIES 2. ENDANGERED SPECIES 3. VULNERABLE SPECIES 4. RARE SPECIES 5. ENDEMIC SPECIES 6. EXTINCT SPECIES
  5. 5. FLORA AND FAUNA • FLORA AND FAUNA REFER TO PLANT AND WILDLIFE, RESPECTIVELY. • THE INDIGENOUS PLANT AND WILDLIFE OF A GEOGRAPHICAL REGION IS OFTEN REFERRED TO AS THAT REGION’S FLORA AND FAUNA. • BOTH ARE COLLECTIVE TERMS, REFERRING TO GROUPS OF PLANT OR WILDLIFE SPECIFIC TO A REGION OR A TIME PERIOD. • FOR EXAMPLE, THE FLORA AND FAUNA OF A WARM REGION MAY CONSIST OF TROPICAL TO WARM-TEMPERATE VEGETATION AND EXOTIC SPECIES OF BIRDS.
  6. 6. DEPLETION OF NATURAL RESOURCES • HUMAN USE UP THE FLORAAND FAUNA IN DIFFERENT WAYS SUCH AS MEDICINES , DYES, , FOOD , FODDER ,ETC . • THE GREATEST DAMAGE INFLICTED ON THE INDIAN FORESTS WAS DURING THE COLONIAL PERIOD . ONE OF THE MOST IMPORTANT REASONS FOR THIS WAS CONSTRUCTION OF RAILWAYS . THER HAVE BEEN LOT OF TREES CUT FOR THE RAILWAY TRACKS WHICH WAS BUILT IN INDIA . • THE OTHER REASONS ALSO COULD BE AGRICULTURE , COMMERCIALAND SCIENTIFIC FORESTRY AND MINING ACTIVITIES
  7. 7. TYPES OF FORESTS THERE ARE THREE DIFFERENT TYPES OF FOREST • RESERVE FOREST • PROTECTED FOREST • UNCLASSED FOREST
  8. 8. DISTRIBUTION OF FOREST reserved forest 64% protected forest 25% un classed forest 11% reserved forest protected forest un classed forest HOME
