1 Sampling error in terms of one standard error. 



2 Omitted entries indicate estimates are too crude for 

 use on a State basis. 



' States covered by Forest Survey since January 1, 1947. 



■• States and Coastal Alaska where little or no Forest 

 Survey data were available. In these States either 

 .special surveys were made or Forest Survey data taken 



prior to January 1, 1947, were adjusted to bring the 

 statistics up to date. A special survey was made in Coastal 

 Alaska, using probability sampling, which permitted 

 calculation of the sampling accuracies shown. 



5 States in which Forest Survey field work was sufficiently 

 advanced to furnish a data base for extension to the 

 remainder of the State.
