Table 1 shows ecological and soil health indicators across five distinct conservation management zones within the Whinfield Forest Reserve.
Table 1
| Conservation Zone | Soil Organic Carbon Stock (t C/hat\text{ C/ha}t C/ha) | Mean Soil pH | Vegetation Cover (%) |
|---|---|---|---|
| Zone Alpha | 142.4 | 5.4 | 88 |
| Zone Beta | 98.6 | 6.2 | 74 |
| Zone Gamma | 115.3 | 4.8 | 65 |
| Zone Delta | 156.1 | 5.1 | 92 |
| Zone Epsilon | 124.6 | 5.5 | 81 |
Calculate the mean Soil Organic Carbon Stock across these five conservation zones.
