The forests are to be divided into protection and 

 non-protection forests (by the cantons with sanction 

 of the Bund), the former being such as are located at 

 headwaters or furnish protection against snowslides, 

 landslides and rockfalls, floods, and climatic damage. 

 Most of this segregation had already been made and 

 mapped in consequence of the law of 1876. In 1904, 

 71% of the total forest area had been classed as pro- 

 tective forest; nearly 80% of the communal, and over 

 50% of the private forest property. 



All public forests are to be surveyed and their cor- 

 ners permanently marked by the cantons according 

 to instructions by the Bund, the latter furnishing the 

 needed triangulation survey, and inspecting and re- 

 vising any older surveys free of charge. 



The surveyed public forests are to be fully regu- 

 lated according to a sustained yield management, 

 under working plans made according to instructions 

 by the Cantons, to be sanctioned by the Bundesrath. 

 For the unsurveyed forest areas at least a provisional 

 felling budget is to be determined, as nearly as possible 

 representing the sustained yield. In protection forests 

 the working plans must conform to the objects of these 

 forests, and clearings in these are as a rule forbidden. 

 The fellings are to be made under direct supervision 

 of foresters, and, after being cut, the wood must be 

 measured. Sale on the stump is forbidden, otherwise 

 no interference in the management is intended. 



Up to 1902, under the law of 1876, working plans 

 for 540,000 acres had been made, In 1907, 90,000 

 acres of State forest, and over one million acres of 

 corporation forests were under working plans.
