W. MACKENZIE. Underplanted Larch plantations at Novar in 

 Scotland. Transaction of the Royal Scottish Arboricultural 

 Society, Vol. XXIII, Part. I, January 1910, p. 35-38. 



It is a sylvicultural impossibility in these days to grow a full 

 healthy crop of larch. This has been found to be the case in 

 most parts of Scotland, England, and Ireland. Larch is peculiary 

 susceptible to a fungoid disease, which if given full sway would 

 do an irreparable amount of damage. 



Attempts have been made heretofore to fight this disease, with 

 only mediocre success. But the system employed at Novar has been 

 found by the author, so far, to be a satisfactory solution of the 

 difficulty: that is, he anticipates having a fuller crop of larch at 

 the end of the rotation than would otherwise be the case. 



The larch is planted pure. When the plantations reach the 

 age of from 12 to 15 years the diseased stems are cut away, and 

 none but the soundest and healthiest are allowed to remain, these 

 usually numbering 350 to 600 per acre, according to the activity 

 of the disease. The cut stems can be utilised down to those i x /4 

 inch in diameter, which goes to show that an havoc wrought by 

 the disease can be made good to a certain extent. Scots fir at 

 that age is quite useless, whilst all sizes of larch posts find a ready 

 market, which makes larch plantations particularly fitted for plant- 

 ing with an undercrop. No time is lost in shocking the thinned 

 area with an undercrop, 2 years' seedlings being used. The species 

 used are those that can endure the shade of the 350 to 600 larches 

 that have been retained per acre. Areas have been planted with 

 Abies Menziesii, A. Albertiana, A. grandis, Cupressus Laivsoniana, C. 

 macrocarpa, C. sempervirens, Picea nobilis, P. abies concolor, Thuja 

 gigantea, spruce, silver fir, Douglas fir and beech. 



What revenue may be derived from the wood as a whole can 

 only be conjectured at this stage, but there is no reason to anticipate 

 anything, the author would conclude, but a profitable and satisfactory 

 return.
