Documented climate envelope
| Variable | Observed range | Central range |
|---|---|---|
| Annual mean temperature | -13.19 – 21.85 | -11.39 – 20.95 |
| Temperature of the warmest month | 9.41 – 40.61 | 10.31 – 40.01 |
| Temperature of the coldest month | -37.73 – 7.91 | -35.13 – 3.53 |
| Annual precipitation | 29.72 – 3652.64 | 40.58 – 2625.26 |
| Precipitation seasonality | 6.8 – 141.52 | 7.22 – 137.44 |
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 | 21 – 37.38 | 24.9 – 31.8 |
| Clay | % | 16.6 – 33.04 | 23.3 – 29 |
| Coarse fragments | % | 8.32 – 22.9 | 11.6 – 19.2 |
| Total nitrogen | g/kg | 2.68 – 7.01 | 4.24 – 5.73 |
| pH | — | 5.06 – 6.56 | 5.3 – 6.1 |
| Sand | % | 21.6 – 50.3 | 27.4 – 39.9 |
| Soil organic carbon | g/kg | 46.89 – 132.35 | 64.05 – 106.97 |
These soil preferences should be compared with the site profile and the confidence of the local data.
