Documented climate envelope
| Variable | Observed range | Central range |
|---|---|---|
| Annual mean temperature | 15.31 – 29.91 | 17.47 – 29.61 |
| Temperature of the warmest month | 20.23 – 40.91 | 21.85 – 40.37 |
| Temperature of the coldest month | 8.03 – 22.89 | 8.11 – 22.39 |
| Annual precipitation | 34.84 – 4960.86 | 64.48 – 4736.7 |
| Precipitation seasonality | 22.7 – 180.92 | 27.5 – 165.44 |
These values describe the documented climate envelope of the taxon. They are not, by themselves, a local recommendation.
Documented soil preferences
| Variable | Unit | Observed range | Central range |
|---|---|---|---|
| Cation exchange capacity (CEC) | cmol(+)/kg | 5.04 – 41.99 | 6.4 – 35.67 |
| Clay | % | 10.33 – 48.68 | 14.18 – 43.52 |
| Coarse fragments | % | 0.7 – 28.91 | 1.45 – 25.3 |
| Total nitrogen | g/kg | 0.36 – 11.22 | 0.4 – 5.05 |
| pH | — | 4.4 – 8.38 | 4.5 – 8.12 |
| Sand | % | 21.14 – 82.56 | 29.1 – 77.42 |
| Soil organic carbon | g/kg | 3.2 – 96.43 | 3.7 – 71.05 |
These soil preferences should be compared with the site profile and the confidence of the local data.
