Documented climate envelope
| Variable | Observed range | Central range |
|---|---|---|
| Annual mean temperature | 10.97 – 23.51 | 12.23 – 22.61 |
| Temperature of the warmest month | 26.71 – 34.89 | 28.57 – 34.59 |
| Temperature of the coldest month | -4.89 – 13.49 | -3.51 – 13.01 |
| Annual precipitation | 456.14 – 1915.64 | 557.48 – 1788.38 |
| Precipitation seasonality | 8.76 – 64.28 | 11.04 – 56.72 |
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 | 7.2 – 25.52 | 11.5 – 19.7 |
| Clay | % | 1.82 – 27.28 | 3.1 – 12 |
| Coarse fragments | % | 0.2 – 7.98 | 0.9 – 3.8 |
| Total nitrogen | g/kg | 2.37 – 19.96 | 5.82 – 13.31 |
| pH | — | 4.5 – 6.8 | — – — |
| Sand | % | 28.42 – 94.9 | 75 – 92.5 |
| Soil organic carbon | g/kg | 14.72 – 111.42 | 29.4 – 64.4 |
These soil preferences should be compared with the site profile and the confidence of the local data.
