‘Forestry land’ is a land use concept referring to lands with no other priority assigned except forestry. ‘Forest land’ is a land cover concept referring to lands, which are estimated to produce at least 1 m3 of wood per hectare and year as a long-term average. Data are from [12] and from METLA (A. Ihalainen, pers. comm.). While the location of the study area is the same as in [8] the geographical borders of regions slightly differ and, in particular, region 15 in the very north was not reported in [8].
