of a sustained-yield plan by some 

 of the larger private operators 

 reduce the cut appreciably. 



In 1939 annual sawlog drain in 

 this unit totaled nearly 750 mil- 

 lion board feet, practically all 

 ponderosa pine. 



In the Deschutes River unit, 

 the second in volume of sawlogs 

 produced, large-scale operations 

 began about 1916 in the Bend dis- 

 trict and reached a peak in 1925 

 when approximately 345 million 

 board feet was cut. Although 

 this record was closely approached 

 in 1929, production remained fairly 

 stable during the period 1925-36. 

 It is doubtful whether the cut will 

 ever again reach the 1925 figure, 

 but it will probably average about 

 a quarter billion annually for a 

 considerable time. As in the Klam- 

 ath Plateau unit, the cut may 

 be considerably reduced through 

 adoption of sustained-yield man- 

 agement by the larger operators 

 and limitation in the sale of Fed- 

 eral-owned timber. Production 

 in the South Blue Mountain unit 

 showed a large increase during 

 the latter part of the period,
