NFI Cockpit - Trends of Forest Indicators in Switzerland

The National Forest Inventory NFI is the most important source of data on the state and change of the Swiss forest. The NFI’s indicator set currently consists of 64 international and national indicators for sustainable forest management. This large number of indicators makes an overall interpretation difficult. Therefore, the mathematical-graphical instrument Swiss NFI Cockpit was developed to show the general trends in space and time:

NFI indicators by criteria

Legend

The NFI indicators are grouped according to the 6 European criteria for sustainable forest management. If a positive or negative change in value of an indicator between two inventories is statistically significant, a numerical value of +1 or -1 is given. If the change was not significant a zero is given. If data is missing (in either or both of the inventories compared), the indicator is not considered (no value available). For each criterion the mean of all indicators is calculated. The general trend is calculated as the mean of these criteria trends.
