1
Consider the climate of the area where grow pines and larch. In European Russia the climate is mild, the wood of larch and pine in its properties is very different from the kinds of trees that grow in Siberia. Wood of a larch of the middle band is loose and easily comparable to the normal wood pine. The thickness of the annual rings they are about the same - 4 mm.
2
When trying to distinguish pine from larch not only rely on the texture. The breed they have one sound. Perhaps, only an expert will feature a bright and decorative wood larch. Often in the literature it is recommended to evaluate the resin-passages, characteristic of conifers. They are thin channels filled with resin. Pine, they are larger and much more. But in practice this method is used rarely.
3
Pay attention to the bark of trees edging the boards of coniferous wood. From larch by the action of oxygen, air and light, the crust acquires a cherry red color sharply different from the color of pine bark. In addition, the boards of larch is much harder.
4
To distinguish between these two wonderful tree, the most basic property of a larch. With a long stay in water, it sinks. Partly this is due to the limitation in wider use. Lower the piece of wood with a thickness of 5 mm and watch him for 2-3 weeks. If not drown, it is pine.
5
The larch is easier to compare with the oak than pine. For example, Venice stands on piles made of larch, because of the pile of concrete is not kept in the water the load. But its wood is much harder to handle than pine wood. It is about 30% denser and heavier. Gently hold a wooden surface with your fingernail. If it remains a trace, then it's pine. Note that the wood of the Siberian Angarsk pine wood is denser than its "European cousin".
6
Consider one more time. In the same forest grow a variety of different pine and larch, which vary greatly in appearance and in their internal characteristics. Pine, for example, grown on the Sunny and high ground is more dry and dense wood than a tree that grew near the swamps. The wood of this pine is softer.

For the identification of wood of one or another tree, use fire, observing all safety precautions. According to the research, which was conducted by specialists of the Moscow State Forest University, increased fire resistance of wood of the Siberian larch 2 times higher than normal wood pine.
