As a result of such "quality" factors, lumber 

 and veneer plants — particularly those dependent 

 on hardwoods — are experiencing increasing diffi- 

 culties in obtaining the quality of timber needed 

 for profitable operations. 



Some of the continuing decline in quality of 

 timber has been offset by technological improve- 

 ments in logging and manufacturing, and by de- 

 velopment of new products such as hardboard and 

 particleboard. Further technological changes are 

 undoubtedly to be expected. But quality of tim- 

 ber resources nevertheless can be expected to 

 continue to be of major importance in deter- 

 mining the competitive strength of the timber 

 industries.
