There's a closely-guarded secret lurking in the Finnish forests. The growing stock, the net annual increment, and the fellings per ha of these forests give a picture of the average resource base, growth, and harvesting intensity in each country. Net annual increment (NAI) is the gross increment less natural losses over a given period. The average resource base (i.e., growing stock per area) is highest for SwedenCited by: 3.
According to LUKE (Natural Resources Institute Finland), the average total harvest in Finland amounted to only 80% of the maximum sustainable yield in the s - reaching 83% in the last three record-breaking years. All this is based on effective active forestry in Finland, which enables forests to grow more and act as carbon sinks. Forest management methods in Finnish state-owned forests Metsähallitus manages million hectares of commercial multiple-use forests in Finland. Forest management is .
“Finnish forests are an ideal setting to gain healthy exposure to the diverse microbiota because, due to our cold winters, we lack the more dangerous disease-causing pathogens,” Sinkkonen says. And there’s always a forest nearby, usually within walking distance, even in . The growing stock in Finnish and Swedish forests, where Metsä Board procures most of its wood, is currently increasing by 30–40 per cent annually. It is possible to make more packaging from.

Get this from a library. Certain regional features in the growing stock of the Finnish forests. [Matti Häkkilä]. GROWING STOCK HAS STEADILY INCREASED OVER LAST 50 YEARS According to the Finnish National Forest Inventory (NFI) the volume of growing stock has increased by more than 40% sincebeing now 2, million m 3.
In Europe, over the last 25 years, the total growing stock in forests has increased by an average of million m3 each year. The most common tree species in. There are several potential causes for the increased growth of the Finnish forests, including forest management.
In the past, low-volume stands and forest pastures were common (Ilvessalo,Ilvessalo,Kuusela and Salminen, ) and the gradually increasing growing stock has increased the annual growth (Siiskonen, ).Until the s, selective logging removing the largest trees Cited by: The annual growth of the forests of Finland has more than doubled in less than a century.
While the increased growing stock and more efficient silviculture have contributed to the observed growth increase, there are also solid grounds for assuming that environmental changes have played a by: Finland belongs mainly to the boreal (northern) forest region, the taiga.
Finland is a land of forets: We have forests circa 4,5 ha to one inhabitant. The volume of forests in whole Europe - except Russia - is some n. ha to one inhabitant, only. From growing stock of Finnish forests will fell yearly 80 million cubic metre, approximately.
Carbon stocks in forests and the soil are extensive, and are constantly growing due to the increasing volume of growing stock. Carbon balance is currently positive in Finnish forests, with an annual net sequestration of 22 million tonnes of CO 2. The share of wood-based fuels of overall energy consumption in Finland is about.
The state of Finnish forests has improved. Finland’s growing stock volume has increased 40% over the last four decades. At the same time, the aggregate forested area has remained almost unchanged and an amount corresponding with the present volume of growing stock has been harvested and utilised to create prosperity for Finnish society.
The volume of the growing stock in Lapland is less than could be supposed on grounds of the large area of forest land (Table 3). Naturally it is due to the low mean volume of the growing stock in Lapland (Table 4).
The mean annual growth of the growing stock in Lapland is only 30% of that in South Finland (Tomppo et. The majority of forests in Finland are predominantly coniferous, with broadleaves often growing in mixed stands.
Forest area The use of forestry land is subject to a variety of widely different and simultaneous aims, needs and wishes: wood production, recreation, nature protection, tourisms and landscape management. Forest sector in Finland.
/ Forest Facts. One would not exist without the other: forest industry ensures that there is a buyer able to pay for the timber growing in forests, and forestry ensures that there is a steady supply of raw material for the forest industry.
The Finnish Forest Centre is the regional forest authority. publishes articles from Finnish forest and forest sector. In our weekly news we tell you about the sustainable use of forests in Finland.

Ecological characteristics of Finnish forests 10 Development of mass production: competence, technology and markets 11 growing stock and annual increment of growing stock by ownership category 14 Figure 2: Output from forestry, wood and paper is mainly exported, waste is Finnish national and regional forest strategies and File Size: 3MB.
The growing stock given as standing volume per hectare is on the average of l80 m 3 in Lithuania. In nature stands, the average growing stock in all Lithuanian forests is about m 3 per hectare. Total annual growth comes to 11 m 3 and the mean timber.
According to the National Resources Institute of Finland the growing stock of forests has increased by more than 40% over the last 40 years.
2,3 billion m3 of wood have been harvested and used for further production of wood products over the same period (ib.).
With Finnish forests growing nearly twice as fast as they were in the s, the amount of wood that can be sustainably extracted from them has nearly doubled, the report notes. The other half of Finland’s wood production goes mainly to lumber or pulp and paper products, where efficient technologies also help to improve cost-effectiveness and.
Over 60% of forests are privatly owned Forest ownership category Forest land area Growing stock Annual increment Commercial roundwood removals Share (%) Private Companies - - State Other (municipalities, - - parishes, associations) Forests sequestrate nearly 40% of the CO2 emissions of.
Germany also had the largest growing stock in forests available for wood supply insome billion m 3, while Finland, Poland, Sweden and France each reported between and billion m 3. The total volume of stock in Finnish forests amounts to nearly 2 billion cubic metres. This amount of timber would make a metre wide and 5-metre high wall around the globe.
For as long as there has been an independent Finland, the increment of stock has. Finland have more standing timber per hectare that in Finland’s northernmost areas. For example, Etelä-Savo region has around 5% of Finland’s total forests but 8% of the country’s timber.
By contrast, Lapland has around 35% of Finland’s forestry land but only 16% of the total amount of timber. Amid widespread reports of deforestation, some nations have nevertheless experienced transitions from deforestation to reforestation.
In a causal relationship, the Forest Identity relates the carbon sequestered in forests to the changing variables of national or regional forest area, growing stock density per area, biomass per growing stock volume, and carbon concentration in the by:.
The species composition has changedless in terms of growing stock volume than in terms of species predominance. Pure stands 17 account for 55% of all forest land, stands with some mixing 18 account for 31% 19, and actual mixed stands account for 13%.
The 12th Finnish forest inventory () shows that there are more forests than ever growing in Finland. The growing stock is today 2,5 billion The growing stock. The growing stock is young, the forests are growing quickly and need to be thinned,” he said.
“We are just about ready,” he said of the project. “The only things we need now are environmental and building permits, the plant will be built in 30 months,” Nivala explained.
