| This study's objective was to assess carbon (C) pools and fluxes in an even-aged mature forest, a regenerating forest, and a pasture in sub-Boreal British Columbia near Hixon, and in the Aleza Lake Research Forest. Net flux of carbon dioxide (CO2) for the pasture was measured by micrometeorological methods in 2001 for the growing season and belowground respiration was measured for the non-growing season, resulting in a net flux of 32.1 ± 0.1 g C m−2. In an 8-year-old regenerating clearcut net CO 2 flux was measured over the growing season using micrometeorological methods, resulting in a net sink of −0.05 ± 0.004 g C m −2. Measurement of total C pools showed that the mature forest was the highest, the 18-year-old pasture was second highest, and the 18-year-old regenerating forest was lowest. Analysis of an orthophoto with a land type classifier program showed that the area surrounding the Hixon study sites was 66% mature forest, 16% regenerating forest, and 13% pasture. |
