Douglas Fir and Oak: Good in uneven-aged woods. 

 Underplant the Oak at 40 years, and both species will 

 then arrive at maturity together. 



Douglas Fir and Scots Pine: Not a good mixture in 

 even-aged woods, as the fir grows too fast. 



Larch and Silver Fir: Good in uneven-aged woods. 



Larch and Spruce or Sitka Spruce: Fairly good in 

 uneven-aged woods where there is a good supply of 

 moisture. 



Larch and Scots Pine: Fairly good on soil suited to 

 the Pine. The soil is apt to deteriorate, when either 

 species may be taken out and the other underplanted at 

 about 30 years. 



Larch and Corsican Pine: On moist sandy soils this 

 mixtm'e is good, even height growth being maintained. 

 Very good for pit wood. 



Spruce and Scots Pine: Not a good mixture, as the 

 Scots Pine will suppress the Spruce in early life, while if 

 Spruce are in greater number the Scots Pine will be 

 dominated later. 



Scots Pine and Beech: Fairly good mixture if pro- 

 tection is given to the Beech while young. Beech 

 does well as an undercrop to Scots Pine under a hght 

 canopy. 



Beech and Oak: A good mixture on soil suited to the 

 Oak, but is better in uneven-aged woods. 



Scots Pine and Corsican Pine: Good mixture on moist 

 sandy soUs, especially for pitwood. A percentage of the 

 Scots Pine can be left, and underplanted with Beech and 

 Douglas Fir.
