Abstract

Abstract

To characterize soil CO2 under different forest types and several years after a clear-cut harvest, soil CO2 evolution and soil air CO2 concentrations were measured at three sites in Maine: the Howland Integrated Forest Study (HIFS) site, the Bear Brook Watershed in Maine (BBWM) site, and the Letter E township (Letter E) site. Soil CO2 evolution means ranged from 0.19 to 0.32 g m−2 h−1 among sites, whereas soil air CO2 concentration means ranged from 1023 µL L−1 for the O horizon to 3296 µL L−1 for the C horizon for the 1990 growing season. Soil CO2 evolution and soil air CO2 concentrations were similar under deciduous and coniferous forests and 4 to 6 yr after harvest. Limited multiple-year data suggest that significant annual variations in temporal patterns of these properties exist as a function of short-term climatic factors. These data suggest that soil CO2 evolution and soil air CO2 concentrations may be somewhat similar across a diversity of soil types, forest types, and forest conditions at any point in time for northern New England.
