How is pine tree useful?

Answer 1

Pines are among the most commercially important of tree species, valued for their timber and wood pulpthroughout the world. In temperate and tropical regions, they are fast-growing softwoods that will grow in relatively dense stands, their acidic decaying needles inhibiting the sprouting of competing hardwoods. Commercial pines are grown in plantations for timber that is denser, more resinous, and therefore more durable than spruce (Picea). Pine wood is widely used in high-value carpentry items such as furniture, window frames, paneling, floors and roofing, and the resin of some species is an important source of turpentine.

Many pine species make attractive ornamental plantings for parks and larger gardens, with a variety of dwarf cultivars being suitable for smaller spaces. Pines are also commercially grown and harvested forChristmas trees. Pine cones, the largest and most durable of all conifer cones are craft favorites. Pine boughs, always appreciated, especially in wintertime for their pleasant smell and greenery, are popularly cut for decorations. A number of species are attacked by nematodes, causing pine wilt disease, which can kill some quickly. Pine needles serve as food for variousLepidoptera. See List of Lepidoptera which feed on Pines.

Because pines have no insect or decay resistant qualities after logging, they are generally recommended for construction purposes as indoor use only (ex. indoor drywall framing). This wood left outside can not be expected to last more than 12-18 months depending on the type of climate it is exposed to. It is commonly referred to as several different names which include North American timber, SPF (spruce, pine, fir) and whitewood.

Answer 2

pine trees are oxygen and they grow pine cones which open and close when predicting rain

Answer 3

Conifers (pines, firs, etc.) are an important source of softwood for paper making, fence poles, and so on. Conifers are extensively grown commercially in large plantations and forests.

Answer 4

Pine trees help reduce CO2 output because of photosynthesis. It also provides a source of shelter to some animals and a resource to us.
