THE PLACE OF PINUS CONTORTA IN BRITISH SILVICULTURE
Forestry Commission
This north American pine has a wide geographical range and shows sufficiently marked differences between races to justify their consideration as two, if not three, distinct trees. Recent assessments in provenance collections have underlined these differences, and in particular the high value of the coastal race as distinct from the inland race as a shade-caster and as a suppressor of vegetation. While the pine's use is limited to the afforestation of the poorer moorland sites, there is within these limits considerable scope for its introduction in one or other of its forms, either pure on the poorest sites where often nothing else is worth planting, or in mixture on rather better sites to assist in the establishment of more valuable species. The author considers each site briefly in turn, using the classification in Anderson's Selection of Tree Species and drawing on his own experience of the value of the tree.
