in the North of Sweden forests has been the rapid growth of the north american kontorta pine with the help of. The rapid growth means that forests absorb more efficiently the carbon dioxide from the atmosphere. This will prevent climate change.

a resource centre, the researcher thinks that kontorta pine viljelyjä should also consider Finland to the forests to obtain additional growth.

– Effective carbon sequestration is the opinion of a good justification for such a foreign type of wood use, natural resources center special researcher Seppo Ruotsalainen said.

kontorta pine faster growth in nordic conditions has been confirmed in Sweden.

It grows to harvesting the mature 35-40% faster than ordinary pine, Sweden Skogforsk-forest research institute forest tree breeding research Mari Suontama tell.

Also Luke Seppo Swedish according to kontorta pine quick stature, but is strong evidence.

– Its volume growth is up to one-third of domestic species of wood better.

Both in Finland and Sweden was studied already in the 1970s kontorta pine growth.

At the time, the reason was not climate change but the fact that in both countries, the forests had grown slowly. The bottom of the bay on both sides woke up to take care of the forest industry raw material adequacy in the future.

kontorta pine from the sought forests grow faster.

Finland kontorta pine were planted in the end about 10 000 hectares. After this, the plantations, the practice was discontinued.

in Sweden instead kontorta pine plantations continue to this day and has become the North of Sweden the third most important forestry tree species domestic pine and spruce after.

kontorta pine planting in Sweden is only allowed 60 of latitude, i.e. in practice the Stockholm above. There it is planted on approximately 600 000 hectares.

Diseases and pests threaten the Finnish species of wood

the type of wood park, executive director Jukka Reinikainen think Finland would be the time to think about foreign tree species growing in the forests of the global warming caused by the disease and pest risk.

Visit tree species threat can be reduced.

– Our own species, you do not necessarily stay so healthy in the new situation at. Now, for example, printed insect has already done extensive damage to our six sizes, Reinikainen says.

Finnish tree species are plagued by disease and pests are often damaging foreign species.

for Example, the North American west coast native douglas fir is not printed on the can.

– Douglas fir is quite different puusuku than Finnish spruce. Printed no part in that increase, and certainly never learned about it.

Reinikainen, the Finnish conditions are suitable, in particular the three foreign species of wood. They are douglas fir, a variety of larch and kontoramänty.

All these types of wood is already grown in Finland, but extensive cultivation, they have not come.

Swedish company with extensive kontorta forests

Swedish higher around 280 000 hectares kontorta forests are Swedish SCA forest left in. The company started kontortan plantations in the 1970s and has continued them ever since.

– the Largest plantings we did in the 1970s and 1980s. In the 1990s the pace was a little slower. Today, we’re planting about 20% of our forests kontortalla, SCA-company information director Björn Lyngfelt tell.

Also Lyngfelt assure that kontorta pine will grow about 40 percent faster than ordinary Swedish pine.

a Fifth raw material

the Swedish company’s first major kontorta forests come in final felling in 10-15 years from now, i.e. about 20-30 years earlier than the usual Swedish pine would become.

Kontortan is becoming the largest raw material source of SCA.

When logging starts, kontorta pine share of raw aineestamme is about one-fifth i.e. about one million tonnes to five million tonnes, Björn Lyngfelt says.

to date, the SCA has used thinning and storm damage come kontorta pine mainly kuitupuuna pulp to the soup. Lyngfelt assure you that it is also suitable for sawing goods.

– Particularly well-suited to panels and joinery industry. Building stuff be it is not as good, because it will break more easily than ordinary pine.

Problems in the upbringing of

Kontortan education has also been a problem in Sweden. In the initial stage the seedlings were planted in the wrong kind of planting pots, which are not decomposed well enough. Tree roots are not developed well enough and the trees became sensitive to crash.

kontorta pine rear wheelie bar, easy sensitivity add, that it is an ordinary pine thicker neulasto you. SCA kontorta woods crash did a lot of wood in the fierce storms of ten years ago.

after the company changed kontortan reared by earlier thinning. The tree remains, therefore, more time to develop a root system and wind endurance.

Saami and environmentalists criticized

in Sweden, environmental organizations have criticized the foreign species of large-scale plantings.

the Criticism is mitigated it, that kontorta pine does little to prevent the recurrence of naturally in Sweden. This is due to the fact that kontorta pine cones open normally only on forest fires, which in Sweden is just not there. Kontorta pine is therefore the power of the Swedish forests naturally without planting.

kontorta forests are in Sweden, sustainable forest management, FSC-certification in the district.

the Most kontorta forests are in Sweden criticized by the sami, with reindeer hide in the dense kontorta forests.

in Finland, the forest industry is not enthusiastic about the

Finland kontorta pine cultivation not been since the 1970s. The background may have been in the forest industry reluctance to change established practices.

Industry does not have a great desire to use a foreign species of wood, because the new raw material may require a different processing technologies, natural resources center special researcher Seppo Ruotsalainen estimates.

a Foreign tree species for large-scale farming starting a also includes demand risks.

There is a certain kind of vicious circle. Forest owners should not start to cultivate before the new wood sales is a certainty. On the other hand, the industry does not change refining processes before the new wood as a raw material has a lot to offer, Seppo Ruotsalainen point out.

Kontortaa is processed further

in Sweden kontorta pine research and breeding has continued since the 1970s. Western neighbor is developed for Nordic conditions even more suitable varieties.

– Forestry has been particularly interested in using these third processing round applicant, Sweden Skogforsk-forest research institute senior researcher Ulfstand Wennström tell.

He will see that also in Finland now would be a good opportunity to use Sweden processed kontorta positions.

the Natural resources agency and Skogforsk between now research collaboration. Finland has been established, for example, the swedes in cooperation with two kontorta pine research.

a Special interest in finland, the issue is not the case.

– it’s Not so far not achieved a breakthrough, special researcher Seppo Ruotsalainen said.
