What is Carbon Sequestration in a High‐elevation, Subalpine Forest about?

## Abstract We studied net ecosystem CO~2~ exchange (NEE) dynamics in a high‐elevation, subalpine forest in Colorado, USA, over a two‐year period. Annual carbon sequestration for the forest was 6.71 mol C m^−2^ (80.5 g C m^−2^) for the year between November 1, 1998 and October 31, 1999, and 4.80 mol C m^−2^ (57.6 g C m^−2^) for the year between November 1, 1999 and October 31, 2000. Despite its evergreen nature, the forest did not exhibit net CO~2~ uptake during the winter, even during periods of favourable weather. The largest fraction of annual carbon sequestration occurred in the early growing‐season; during the first 30 days of both years. Reductions in the rate of carbon sequestration after the first 30 days were due to higher ecosystem respiration rates when mid‐summer moisture was adequate (as in the first year of the study) or lower mid‐day photosynthesis rates when mid‐summer moisture was not adequate (as in the second year of the study). The lower annual rate of carbon sequestration during the second year of the study was due to lower rates of CO~2~ uptake during both the first 30 days of the growing season and the mid‐summer months. The reduction in CO~2~ uptake during t
