Scots Pine (Pines sylvestris) "Urwald" occurs t} r pically in High- 

 land Valleys on the slopes, the form is frequently strip-like or 

 wedge-shaped along the Valley. Locheil Old Forest (Invernessshire) 

 is described in detail (including measurements of trees; the ground 

 Vegetation consists of Calluna, Erica Tetralix, Vaccinium Myrtülus, 

 Pteris. Juniper occurs in open places in both birch and pine woods 

 and sometimes forms a fringing belt at the Upper limit. 



Oak (Quercus) "Urwald" occurs up to 300 metres, but in the 

 Highlands only up to 200 metres altitude. These woods occur 

 mainly on the lower Valley slopes or fringing lakes, and have been 

 almost universally coppiced for long periods. 



Referring to plantations as opposed to natural woods, it is noted 

 that in plantations ranging from 50 to 200 years old, there is a 

 varied and in some cases a vigorous ground Vegetation, but in no 

 case examined was there a typical woodland fiora comparable to 

 that of natural woods. Observations are also given on the habit of 

 trees growing in plantations as compared with "Urwald". The 

 application of these observations to future afforestation is also dealt 

 with. W. G. Smith.
