Documented climate envelope
| Variable | Observed range | Central range |
|---|---|---|
| Annual mean temperature | 13.41 – 29.17 | 15.81 – 28.79 |
| Temperature of the warmest month | 20.23 – 41.31 | 21.85 – 41.25 |
| Temperature of the coldest month | 1.05 – 22.89 | 2.01 – 21.99 |
| Annual precipitation | 9.08 – 4960.86 | 13.28 – 4736.7 |
| Precipitation seasonality | 22.7 – 197.44 | 27.5 – 184.48 |
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 | 4.61 – 39.19 | 6 – 26.27 |
| Clay | % | 12.31 – 48.68 | 15.55 – 43.52 |
| Coarse fragments | % | 0.7 – 26.79 | 1.45 – 21.07 |
| Total nitrogen | g/kg | 0.45 – 6.97 | 0.53 – 4.83 |
| pH | — | 4.4 – 8.38 | 4.5 – 8.2 |
| Sand | % | 21.16 – 82.56 | 35.7 – 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.
