Thinning turned an upland forest into a temporary carbon source and made a peatland forest an even stronger carbon source | University of Helsinki
A recent study highlights how forest thinning significantly influences the ability of forests to store or release carbon.

Oivallinen ja perusteellinen vastine Juha Mikolalta ja Paavo Ojaselta @luke.fi kasvihuonekaasuinventaarin hiilitaselaskelmiin kohdistuneeseen kritiikkiin. www.metsalehti.fi/artikkelit/k...
Kannanotto: Luonnonvarakeskus vastaa kritiikkiin hiilitaselaskelmista - Metsälehti
"Asian käsittely oli yksipuolista ja kritiikki perustui merkittävältä osin tietämättömyyteen ja väärinymmärryksiin."

Orpon hallitus piti kiinni kiistellyistä kriteereistä vanhoille metsille – järjestöt: ”Farssi” ja ”totaalinen rimanalitus”
Hallitus päätti lahopuun määrää ja puuston ikää koskevista kriteereistä, joiden perusteella se suojelee vanhat metsät. Suojelua edellyttää EU.
