Documented climate envelope
| Variable | Observed range | Central range |
|---|---|---|
| Annual mean temperature | 23.75 – 28.85 | 24.51 – 28.49 |
| Temperature of the warmest month | 33.09 – 40.05 | 33.81 – 39.75 |
| Temperature of the coldest month | 14.29 – 22.87 | 16.49 – 22.39 |
| Annual precipitation | 601.36 – 3010.18 | 678.82 – 2783.44 |
| Precipitation seasonality | 50.64 – 127.5 | 53.4 – 125.22 |
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 | 5.71 – 39.86 | 7.25 – 28.9 |
| Clay | % | 12.31 – 34.1 | 15.55 – 31.1 |
| Coarse fragments | % | 4.54 – 28.91 | 6.6 – 25.3 |
| Total nitrogen | g/kg | 0.4 – 11.22 | 0.47 – 5.05 |
| pH | — | 5 – 6.88 | 5.2 – 6.5 |
| Sand | % | 32.52 – 71.47 | 38.92 – 65.05 |
| Soil organic carbon | g/kg | 4.73 – 90.21 | 6.28 – 53.1 |
These soil preferences should be compared with the site profile and the confidence of the local data.
