| d1.3 -class | | Classification of trees according to the diameter at the breast height cf. Hirvelä et al.(2017).≤ 10 cm: < 10.5 cm11-20 cm: 10.5 ≤ x < 20.5 cm21-30 cm: 20.5 ≤ x < 30.5 cm≥ 31 cm: ≥ 30.5 cm

| Management category | | Classification is based on the NFI data concerning administrative restrictions for wood productionWood production: Land available for wood production without restrictions or with restrictionProtected forests: No wood production allowed
|
| NFI age | | Classification is based on the estimated mean age of a stand of NFI plot. The stand age is increasing along the calculation years and the age resets to zero with final cutting.≤ 20 y: < 20.5 y21-40 y: 20.5 ≤ x < 40.5 y 41-60 y: 40.5 ≤ x < 60.5 y 61-80 y: 60.5 ≤ x < 80.5 y 81-100 y: 80.5 ≤ x < 100.5 y 101-120 y: 100.5 ≤ x < 120.5 y ≥ 121 y: ≥ 120.5 y
