SIMULATING CANOPY GAP FRACTION OF COMPLEX 3D FOREST SCENES OF PICEA SITCHENSIS (SITKA SPRUCE)
Forestry 3D canopy modelling gap fraction
2015/9/8
We present an application of 3D canopy modelling for assessing the structural accuracy of complex 3D structural models of
Sitka spruce. Such models can be used to simulate canopy reflectance at the l...
Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands
soil calcium depletion Welsh uplands plantation forestry
2009/6/5
A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop wi...
Cycling of nutrient base cations in a twelve year old Sitka spruce plantation in upland mid-Wales
Forestry base cations
2009/3/24
The effects of the early growth of plantation forestry on the biogeochemical cycling of potassium, calcium and magnesium have been investigated in a stand of 12 year old Sitka spruce and adjacent moor...
Effects of five years of frequent N additions, with or without acidity, on the growth and below-ground dynamics of a young Sitka spruce stand growing on an acid peat: implications for sustainability
acid canopy application nitrogen acid organic soil soil water young Sitka spruce
2009/3/5
A field manipulation study was established to demonstrate effects of simulated wet N and S deposition on a young (planted 1986) stand of Sitka spruce growing on a predominantly organic soil in an area...
Variation in Growth of 20-Year-Old Provenance Trial of Sitka spruce(Picea sitchensis(Bong.)Carr.)in Great Britain
Sitka Spruce Site-Seed Origin-Provenance Growth Rate-Tree Volume-Tree Diameter at Breast Height
2009/1/14
Variation in growth of the cambial age (tree diameter) and tree volume was investigated in eight seed origins of Sitka spruce Picea sitchensis (Bong.) Carr.) grown at two sites in Great Britain. The ...
The Effect of Wood Specimen Length on the Proportional Saturation of Preservative Fluid in Sitka Spruce(Picea sitchensis(Bong)Carr.)and Corsican Pine(Pinus nigravar.mantima)
Softwood Anatomy Preservation Longitudinal Flow Full Cell Proportional saturation
2009/1/14
In this study, the proportional saturation and the fluid uptake of preservative liquid (that was) applied under the same pressure was investigated comparatively on the various longitudinal length of ...
Effects of Seed Origin and Site on Wood Density of Sitka Spruce(Picea sitchensis(Bong.)Carr.)Grown in Britain
Seed Origin Site Wood Density Sitka Spruce Plantations
2009/1/13
Since density may have a direct influence on wood properties and because density is a factor under genetic control, this study details the effects of seed origins and sites on density. In addition to...
