| Condition variable | Subvariable | Unit | Condition 2015 | Condition 2018 | Change 2018 to 2015 |
|---|---|---|---|---|---|
| The values of the condition variables present the yearly arithmetic average for the respective ecosystem, if not definied differently by the measurement unit. 1: Values are based on data sources that are recorded over long time periods. Changes over time presented here therefore reflect change due to ecosystem extent conversions rather than changes in the data source of the condition variable. - = No figures or magnitude zero. . = Numerical value unknown or not to be disclosed. | |||||
