been exercised over 140,000,000 acres ; working plans were au- 

 thorized for 2 million acres ; reforestation ordered on 12,000 acres ; 

 change of use permitted on 685,000 acres. 



Altogether, the impression is left of activity in all directions.

Twenty-three per cent, of the total area of 

 Swiss Statistics. productive soil is devoted to timber crops. 

 Of this the State forests occupy 5%, the 

 communal and corporation forests 69%, and private woodlands 

 26%. The character of the forested area is shown in the follow- 

 ing table : 



High Forest. Coppice. 



State forest, 94-9^ 5-i% 



Communal and corporation forests, 88.6% 11.4% 



Private wood lands, 89 % 11.0% 



The good effects of technical management are brought out by 

 the yield figures given below. While the average return from the 

 State forests is a little below that of the technically managed 

 communal and corporation forests, the latter probably occupy the 

 better sites. 



Yields per hectare in 1908 



Average for whole country, 2.42 cubic meters 



State forests, 4.08 cubic meters 



Communal and corporation forests, technically 



managed, 4.29 cubic meters 



Communal and corporation forests, not techni- 

 cally managed, 2.46 cubic meters 



Private wood lands, 1.55 cubic meters 



Seventy-six per cent, of the wood used in Switzerland is grown 

 at home while the remaining 24% has to be imported.
