We have estimated in this study the annual net ecosystem productivity (NEP) of Kaziranga National Park by using real-time eddy covariance data. We partitioned the net CO2 flux into gross primary productivity and ecosystem respiration (Re) using standardized method. Estimated annual NEP of the ecosystem 92.93 ± 1.7 g C m–2 year–1 indicated that the forest is a moderate sink of CO2 and is reported for the first time from a forest of Northeast India.

We partitioned the net CO2 flux into gross primary productivity and ecosystem respiration (Re) using standardized method. Estimated annual NEP of the ecosystem 92.93 ± 1.7 g C m–2 year–1 indicated that the forest is a moderate sink of CO2 and is reported for the first time from a forest of Northeast India.
