Bamboos with vigorous biomass production can sequestrate considerable amount of carbon in their biomass and helps in combating global climate change. Thyrsostachys oliveri is a perennial clumping bamboo species with very solid culm and quick growing in nature and it is one of the most preferred bamboo species by farmers. The present study was conducted in a farmer’s field located at Alanellur, Palakkad, Kerala. The clump structure of the bamboo plants was recorded and the destructive sampling was adopted for biomass and carbon storage estimation. Results indicated that the average number of culms at the age of seven years was 3725 ha-1. The average clump circumference was 2.40±0.15 m which accommodated 20.58±3.85 culms. The biomass accumulation Thyrsostachys oliveri at 6th and 7th year was to the tune of 44.11±4.96 and 50.04±14.13 Mg ha-1, respectively and carbon storage was 20.92±2.12 and 23.92±6.14 Mg ha-1 respectively. Higher biomass and carbon storage was observed in aboveground components than below ground, especially in the culms. Soil carbon storage at depths of 0-20, 20-40 and 40-60 cm of the plantation was 19.29±0.30, 20.34±1.49 and 14.40±0.00 Mg ha-1 leading to a cumulative total of 54.02±3.17 Mg ha-1. Based on the growth performance of the species we recommend this species for incorporating in Agroforestry systems and plantations under the humid tropical conditions of Kerala.
