STOCKING THE GBOUND 107 



If the trfies are raised from seed in the home nursery, 

 these decisions must be arrived at several years before 

 the ground is to be stocked. It is for this reason that 

 a planting scheme should be drawn up for at least five 

 years ahead (from which it will be possible to answer all 

 such questions). 



Species for Different Soils. 



The first thing, then, to consider is what soil will suit 

 each individual species. 



To plant a tree on soil totally unsuited to its require- 

 ments is to court disaster. 



When Larch was first introduced into this country it 

 was often planted on any or every class of soil, with the 

 result that in many cases its vitality was lowered and 

 it became more predisposed to attacks of the canker 

 fungus, Peziza Willkommii. 



The best loams are seldom given up to forestry opera- 

 tions, but any small area of this class that may be found 

 in the woodlands should be reserved for growing Ash, 

 which will only grow at its best on these soils. 



Oak, Spanish Chestnut, Larch and Douglas Fir, also 

 require good soil to grow to the best advantage. 



On Stiff Clays : Pedunculate Oak and Spanish Chestnut 

 should form the main crop. 



On Milder Clays: Oak, Spanish Chestnut, Sycamore, 

 Maple, Beech, Elm, and Ash, with Alder, Black, White, 

 and Black Italian Poplars where there is more water in 

 the soil. Also Larch, Norway and Sitka Spruces, Douglas
