measures. On certain types of forest, renewal will 

 result from fire protection alone. In many instances 

 of unrestricted exploitation, however, fire protection 

 alone does not suffice to secure renewal and to pre- 

 vent the lands becoming waste. If protection alone 

 does not suffice to secure forest reproduction, the 

 owners should be required to adopt such measures as 

 may be necessary to accomplish this, with cooperative 

 aid by the public in working out the problem as a 

 practical undertaking. As in the case of fire pro- 

 tection, the additional measures necessary for forest 

 renewal should be made a part of a systematic pro- 

 gram in which the public and private owners engage 

 in a joint undertaking with a common objective. 



The first steps in this undertaking are to deter- 

 mine in each region : 



1. The circumstances under which fire protection 

 alone will not suffice to prevent wasting of the land 

 under prevailing methods of lumbering. 



2. The additional measures necessary to secure 

 conditions favorable for natural renewal. 



3. The classes of land upon which forest growth 

 should be continued. 



4. The cooperation that should be given by the 

 public to make feasible in practice the measures that 

 may be necessary for the owners to take. 



5. The legislation needed to bring these measures 

 into practice, as a part of the State's program of 

 forestry. 



As in the case of fire protection, the plan for spe- 

 cial measures and for forest renewal should be work- 

 ed out through State legislation and administration,
