characteristics of agencies charged with the protection of resources 

 and the provision of outdoor recreation facilities -- were equally 

 important. 



The principal causal factors noted and documented by the Outdoor 

 Recreation Resources Review Commission Reports were: 



(1) Growth 1n total population; 



(2) Growth in leisure time; 



(3) Increased mobility of the total population including 

 transportation; 



(4) Changing population characteristics of the total popu- 

 lation; and 



(5) Concentration of population in urban or metropolitan 

 centers. 



It was concluded that as the levels of these factors rose, the growth 

 of outdoor recreation demand for specific activities or opportunities 

 would accelerate faster than the net increase in total poDulation. 

 Sections 1 and 2 showed that these orinciDal factors in the growth of 

 outdoor recreation demand will exhibit sustained growth both nationally 

 and within the estuarine zone. Therefore, although no specific quan- 

 tification is presently available to project actual recreational demands 

 on and uses of the Nation's estuarine resources, they will certainly 

 increase at substantial rates in the future. It is uncertain at whe- 

 ther the supply of recreation resources will in fact be sufficient to 

 meet this large, if unquantified demand. Continued degradation and
