The survey for the second Swiss National Forest Inventory took place ten years after the first, from 1993-1995. The results showing the condition and development of the Swiss forest are extensively presented and discussed.

The main topics are: forest area, forest site, standing volume, increment, current and future yield, wood assortment, forest type, stand age, tree species, forest regeneration, forest damage, stability, accessbility, management, forest as a habitat, forest edge, biotope value, recreation, avalanche- and rockfall-protection forests, control of sustainability, results by canton, comparison with other European countries.
