NATURAL VEGETATION – this guide gives you a concise, exam-ready overview of NATURAL VEGETATION from Class 11 Geography, written by ConceptScroll editors and reviewed against the latest NCERT textbook.
Tropical Evergreen Forests
Tropical evergreen forests are found in regions with heavy rainfall exceeding 200 cm and consistently high temperatures throughout the year. These forests are dense, multi-layered, and remain green all year round due to the absence of a dry season. The trees are tall, straight, and have broad leaves that are shed gradually, not seasonally. The forest floor receives little sunlight because of the dense canopy. These forests are rich in biodiversity and include species such as mahogany, rosewood, ebony, and rubber. They are mainly found in the Western Ghats, the Andaman and Nicobar Islands, the northeastern states of India, and the foothills of the Himalayas. The dense vegetation helps in maintaining high humidity and contributes to the water cycle through transpiration.
🔗 Connection: Leads to study of tropical deciduous forests with distinct wet and dry seasons.
Frequently asked questions
What is natural vegetation and how does it reflect the climatic and soil conditions of a region?
Natural vegetation is the plant life that grows naturally in a region without human intervention. For example, tropical rainforests in the Western Ghats reflect high rainfall and temperature conditions.
Which of the following factors is the most significant in influencing the distribution of natural vegetation?
Temperature and rainfall
Explain how altitude affects the types of natural vegetation found in mountainous regions.
Altitude affects temperature, which decreases with height, leading to changes in vegetation from tropical forests at lower altitudes to alpine vegetation at higher elevations. For example, in the Himalayas, tropical deciduous forests occur below 1500 m, coniferous forests between 1500 and 3000 m, and alpine vegetation above 3000 m.
