A controlled burn in Niagara Falls, Ontario where the Burn Boss is watching a back fire (lit first and in the background) move towards a head fire (in the foreground) Back burning or a back fire is the term given to the process of lighting vegetation in such a way that it has to burn against the prevailing wind.
Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
Blackberries, wild roses, wood mints, California honeysuckle, currants, and others are common. The flora and fauna varies from area to areas, especially the southern and northern closed-cone pine regions. Soils have low nutrients and are stressed due to a lack of nitrogen. This promotes slow growth.
Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant. It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt , while plant-derived pitch, a resin , is known as rosin in its solid form.
Wood from other locations can also be used, such as the joints where limbs intersect the trunk. Although most resinous pines can produce fatwood, in the southeastern United States the wood is commonly associated with longleaf pine ( Pinus palustris ), which historically was highly valued for its high pitch production.
Destructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols.
