SAMPLE PLOTS IN SILVICULTURAL RESEAECH 89 



Where this is not possible and no natural area is available, it may be highly 

 desirable to add to the experimental forest an area in which the timber is not 

 yet mature, to be maintained without use so that in time it will develop into 

 a natural area. Where suitable natural areas are not already included in 

 national forests, acquisition by other means suggested under Experimental 

 Forests should be considered. 



UTILIZATION OF NATURAL AREAS 



Within natural areas scientific and educational use will be exclusive. The 

 cutting of timber, and as soon as possible grazing use also, should be pro- 

 hibited. General or promiscuous public use will be incompatible with the 

 scientific use of the area, and should be restricted as far as practicable ; and if 

 this is impossible, carefully regulated. The present laws are inadequate to 

 permit the total exclusion of the public or prevent the location of mining 

 claims or the establishment of easements under public-land laws. 



SCTENTTFIO VALUE DEPENDENT UPON PERMANENCY AND STABILITY 



The highest value of natural areas can be maintained only by the total 

 exclusion of all forms of use. Consequently no utilization shall be authorized 

 or changes made in boundaries without the prior approval of the Forester, 

 which will not be granted unless there is certainty that the change will not 

 react adversely upon the plans of the Forest Service or of any related research 

 agency. 



AV ATT, ABILITY OF NATURAL AREAS TO OTHER RESEARCH AGENCIES 



While natural areas will be established primarily to meet the needs of the 

 Forest Service, their use by other research or educational agencies for pur- 

 poses which do not conflict with Forest Service projects shall be allowed under 

 appropriate cooperative agreements approved by the Forester.
