The article discusses how the carbon stock of Finnish forests could be significantly increased by favoring large-sized deciduous trees, especially elm. The current softwood-focused economic forestry with short rotations leads to a small carbon stock. Longer cycle times and growing larger trees could double the carbon stock. Hardwoods also reflect sunlight more effectively than conifers, which combats global warming.
Elm, a fast-growing domestic tree species, is especially highlighted. Its hard and rot-resistant wood could replace tropical hardwoods in construction and furniture. Author Risto Isomäki suggests expanding elm cultivation due to its climate benefits and valuable wood material.
Jos metsissämme käytettäisiin pidempää kiertoaikaa ja suuri osa puista kasvatettaisiin suuriksi tukkipuiksi ennen kuin ne kaadetaan, metsiemme maanpäällinen hiilivarasto voitaisiin kasvattaa ainakin kaksi kertaa nykyistä suuremmaksi.
Lehtipuuvaltaisen metsän heijastavuus on erityisesti kevättalvella ratkaisevasti suurempi kuin tiheän kuusi- tai mäntymetsän.
Vuorijalavan tumman- tai punaruskea puuaines on kovaa, raskasta, lahonkestävää ja ulkonäöltään jopa lievästi eksoottista. Jalava on kotimainen vastaus trooppisten sademetsien kovapuille.
Tästä syystä metsissämme on hehtaaria kohti keskimäärin vain 150 kuutiota puuta.
Why is it worth growing more hardwood trees in Finland?
In order to combat climate change, it would be worthwhile to grow more hardwood trees in Finland. The reflectivity of a deciduous forest, especially in spring and winter, is significantly higher than that of a coniferous forest, which helps prevent global warming.
How big is the carbon stock in Finland's economic forests on average?
In Finland's commercial forests, there are only 150 cubic meters of wood per hectare on average, which is why the forests' carbon stock remains relatively small.
What are the properties of mountain elm wood?
The dark or red-brown wood of mountain elm is hard, heavy, rot-resistant and somewhat exotic in appearance. It is considered the domestic equivalent of tropical rainforest hardwoods.
How tall can a mountain elm grow?
Mountain elm can grow up to 40 meters tall. The most handsome individuals in Finland have been around two meters in diameter.
