Table 2: Factor differences from air baselines for pristine and logged forest soils. Air samples and pristine soil measurements were taken from a forest area approximately 200 yards from the mechanically logged forest region. In the logged forest, the carbon dioxide soil level is 0.75 that of the nearby pristine forest soil, and methane is 9.0.
| Carbon Dioxide | Methane | Water Vapor |
Pristine Forest Soil | 2.76 | 0.63 | 1.40 |
Logged Forest Soil | 2.22 | 5.1 | 1.37 |
