The article claims at least 5.5 degrees Celsius in annual mean temperature for this kind of forest. This is at odds with individual ecoregion/forests listed in the article, such as Magellan subpolar forest (mean annual down to 3 Celsius), and also at odds with some of the ecoregions in Russia included in this kind of forest (lacks articel so far in Wikipedia).

Several of the ecoregions in this section has a mean annual quite low, as the Ussuri mixed forest, Manchurian and West Siberian temperate and mixed forests with annual average almost down to 0 C seen here. I have now changed article to 3 C as lowest threshold. Orcaborealis (talk) 11:47, 4 May 2010 (UTC)
