Sheep Flats blocks. — Three blocks were established of 17.5, 

 5.6, and 20 acres (7.1, 2.3, and 8.1 ha), respectively. The spe- 

 cies mix was approximately 80 percent ponderosa pine and 

 20 percent Douglas-fir. Slopes were generally less than 5 per- 

 cent, with the exception of about 2 acres (0.8 ha) with slopes 

 up to 15 percent. Leave trees were marked and the dominant 

 cutting practice was the shelterwood method with some com- 

 mercial thinning. These blocks were representative of a stand 

 with large harvestable trees that would also be attractive to con- 

 ventional logging operations. 



cruise summary was for 13.5- and 5.6-acre (5.5- and 2.3-ha) units in- 

 itially set up; 4 acres (1.6 ha) were added to the 13.5-acre (5.5-ha) upit. The ad- 

 ditional areas of 4 and 20 acres (1.6 and 8.1 ha) were similar to the cruised 

 units.
