A eucalyptus plantation in final stages at Arimalam.. The type of tree planted may have great influence on the environmental outcomes. It is often much more profitable to outside interests to plant fast-growing species, such as eucalyptus, casuarina or pine (e.g., Pinus radiata or Pinus caribaea), even though the environmental and biodiversity benefits of such monoculture plantations are not ...
Ultisol, commonly known as red clay soil, is one of twelve soil orders in the United States Department of Agriculture soil taxonomy. The word "Ultisol" is derived from "ultimate", because Ultisols were seen as the ultimate product of continuous weathering of minerals in a humid, temperate climate without new soil formation via glaciation .
Pine trees are usually better adapted to a sandy or sandy loam soil, [9] while white spruce trees and fir trees, such as the Douglas fir, prefer fine-texture loams and clay loam soils. [9] Some trees grow well in all types of soil, but in any case, the land must be well-drained for a Christmas tree farm to have a chance of thriving. [9]
These are isolated populations on areas of acidic sandy soil, surrounded by alkaline clays that are poor for pine growth. A study using loblolly pines showed that higher atmospheric carbon dioxide levels may help the trees to endure ice storms better.
To help apply "free-to-grow" regulations in British Columbia and Alberta, management guidelines based on distance-dependent relations within a limited radius of crop trees were developed, but Lieffers et al. (2002) [68] found that free-growing stocking standards did not adequately characterize light competition between broadleaf and conifer ...

These trees grow best on well-drained, light-textured soils on the low ridges of second bottoms and on the high flats of silty alluvium. In the uplands it grows best on the loams and clay loams of lower slopes and coves. The species occurs in 35 different forest cover types. [10]
