Abstract:
Swietenia macrophylla is an economically important tree species. Its moderately fast growth and adaptability to different environmental conditions and good economic returns has made it a popular tree species in Karnataka. The present study aims to know the growth and carbon sequestration of mahogany tree in hilly zone of Karnataka. Twenty-five trees selected from each age gradation of one and half year to four and half year old were selected and evaluated for the growth and carbon estimation. A significant difference is observed among one and half year to four and half year-old mahogany trees for growth parameters such as height (2.73 to 5.11 m), GBH (10.80 to 28.04 cm) and the volume (2.20 to 24.18 m³/ha). Growth pattern of mahogany showed an increasing trend with tree age. Carbon sequestration also varied with tree age. Maximum carbon sequestered by four and half year-old plantation (8.07 t ha^-1) compared to the rest.
