FIRST STEPS TOWARDS AFFORESTATION 17 



allowance of at least 10 per cent, should be made tu 

 spread over the time taken to establish the crop, usualh/ 

 two or three years. This leaves 115,200, enough to plant 

 32 acres. 



Thus it will be seen that to plant annually an area of 

 32 acres, 3 acres of ground are needed for transplants 

 alone. 



To this figure must be added sufficient ground for 

 seed-beds and for other trees that may be needed apart 

 from the plantations. 



Another acre should be left for this, making 4 acres 

 in all, equal to one-eighth of the area to be annually 

 planted. 



If the lines are only 9 inches apart, about one-third 

 less ground for transplants will be needed. (The ad- 

 vantages and otherwise of this are discussed under 

 " Lining Out," Chapter III.) 



If the plants are to be twice transplanted to encourage 

 the growth of fibrous roots, another acre will be needed, 

 unless they are replaced upon the same beds from which 

 they are lifted. 



Hardwoods and Larch require more growing space 

 in the lines than the majority of conifers, so if all or a 

 proportion of these plants are to be used, a corresponding 

 addition must be made to the size of the nursery. 



When ploughed ground or very clean old woodland 

 is to be planted, 2-year 1-year or 1-year 1-year trans- 

 plants or 2-year seedlings may be used. In these cases 

 the area of nursery can be reduced accordingly.
