NFI11

NFI data

The field measurements of the 11th national forest inventory (NFI11) from the years 2009-2013.

National Forest Inventory (NFI)

MELA data

The calculation data for MELA consists of the NFI sample plots defined either as forest land or as poorly productive forest land (scrub land). Due to the small sizes of relascope plots which do not represent a stand properly, sample plots are linked with other sample plots (4-6) similar in terms of stand characteristics. The grouping is made for each sample plot separately resulting as many management units as there are original sample plots. The management unit characters are formed by summarizing sample plots. Management decisions are based on the characteristics of a management unit but the actions are carried out by sample plots. The sample plots represent the variation within the management unit.

Forest management categories

The management units were classified into three categories according to sample plot restrictions concerning wood production:

1. no restrictions for wood production
2. restrictions for wood production
3. no wood production allowed

Management categories of MELA data formed according to the NFI field measurements (2009-2013)
