The trees / Larch - europeisk lärk, sibirisk lärk - Larix decidua, Larix sibirica

Larch

European larch, the most common larch, was brought here as late as the 18th century and can now be found in the south and middle areas of Sweden. Siberian larch, another species, grows in the north. There are several other species and hybrids of larch, growing in plantations and as ornamentals. The needles are light green and thinner than pine- or spruce needles. The larch is the only conifer felling its needles in autumn. The cones are egg shaped and brown. They usually remain on the tree several years after felling the seeds. The bark is smooth and grayish brown, later turning fissured with reddish purple inside. The larch is a strong growing, storm proof tree with deep, coarse roots. It prefers light, slightly moist soils and can get 600 years old and 40 meters high.


The wood

The wood has reddish brown heartwood and a thin layer of light yellow sap wood. The heartwood is hard and rich in resins and very decay resistant. It is difficult to season without checking and distortion since it shrinks a lot. It is easy to work and to split. Larch has been used in construction work when decay resistant wood was needed. Today it is usedfor construction  work, flooring, windows, telegraph poles, boatbuilding and more.
