UPSC CSE 2025 (Prelims) CSAT Official Paper (25-May-2025)

India's diverse geography supports various forest types:

  1. Tropical Evergreen: High rainfall, dense canopy (Western Ghats, NE).

  2. Tropical Deciduous: Most widespread, shed leaves in dry season (teak, sal).

  3. Tropical Dry Deciduous: Less rainfall, sparse (acacia).

  4. Montane: Varies with altitude (pines, deodars).

  5. Mangrove: Coastal, tidal, salt-adapted (Sundarbans).

Crucial Ecosystem Services:

  1. Climate Regulation:

    • Carbon Sequestration: Forests absorb CO2 (carbon sinks), mitigating global warming by storing carbon in biomass and soil.

    • Temperature Regulation: Moderate local temperatures and influence rainfall through evapotranspiration.

  2. Water Cycle Regulation:

    • Groundwater Recharge: Forest soils enhance water infiltration, recharging aquifers.

    • Erosion Control: Roots bind soil, preventing erosion, landslides, and improving water quality.

  3. Biodiversity Conservation:

    • Habitat: Critical habitats for immense flora and fauna, including endangered species, supporting complex food webs.

    • Genetic Resources: Reservoirs of genetic material for crop improvement and medicine.

  4. Soil Health:

    • Nutrient Cycling: Organic matter decomposition enriches soil fertility.

    • Soil Formation: Roots aid soil formation.

  5. Economic & Social Benefits:

    • Products: Provide timber, fuelwood, medicinal plants, NTFPs (honey, resins), supporting livelihoods.

    • Recreation/Culture: Offer aesthetic, recreational values, supporting ecotourism and embodying cultural significance for indigenous communities.

These services highlight forests' indispensable role in ecological balance and human well-being.
