Have you ever thought as to why forests are important for human beings? Forests are renewable resources and play a major role in enhancing the quality of environment. Areas of heavy rainfall have more dense vegetation as compared to areas of less rainfall.
In India, almost the entire rainfall is brought in by the advancing southwest monsoon (June to September) and retreating northeast monsoons. Due to longer duration of sunlight, trees grow faster in summer. The variation in duration of sunlight at different places is due to differences in latitude, altitude, season and duration of the day. Table 5.1: Temperature Characteristics of the Vegetation Zones On the slopes of the Himalayas and the hills of the Peninsula above the height of 915 metres, the fall in the temperature affects the types of vegetation and its growth, and changes it from tropical to subtropical temperate and alpine vegetation. The character and extent of vegetation are mainly determined by temperature along with humidity in the air, precipitation and soil. TEMPERATURE, PHOTOPERIOD(SUNLIGHT) AND PRECIPITATION
