Thinning Response and Thinning Bias in a Young Scots Pine Stand
The study analyses the annual post-thinning response and thinning bias of a young Scots pine stand as a function of tree size, competition faced by the tree, and competition that is removed around the tree in the thinning treatment. The thinning response of a tree was defi ned as the change of tree growth due to a thinning treatment. The thinning bias was defi ned as the difference between the ...
متن کاملThinning Response and Growth Trends of Seeded Scots Pine Stands at the Arctic Timberline
Growth patterns and reactions of Scots pine (Pinus sylvestris L.) to thinning in extremely harsh climatic conditions were studied in two seeded Scots pine stands located on the arctic timberline. Coniferous trees usually do not form closed stands at the timberline, but occur only in scattered tree groups. The trial was established in two stands in 1985–1986 when the trees were at an age of 47 a...

متن کاملEffect of Early Thinning on the Diameter Growth Distribution along the Stem of Scots Pine
The absolute and relative effects of the fi rst thinning on the diameter growth distribution along the stems were studied in 98 Scots pines (Pinus sylvestris L.) at heights of 1.3, 4, 6 and 8 m. The data cover one 3-year pre-thinning period and four 3-year post-thinning periods in plots with densities varying from 575 to 3400 stems ha–1. A shift in the point of maximum diameter growth down the ...
متن کاملCan Thinning and Fertilizing Young Lodgepole Pine Mitigate Future Timber Supply Challenges?
The effects of factorial combinations of post-thinning density (6, 11, and 16 stems per hectare [sph]) and repeated fertilization on the growth and development of young lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) were investigated in central British Columbia. After 14 years, the effects of density and multi-nutrient fertilization (applied at , 5, and 1 years) on tree h...
