About the statistics
The purpose of the statistics is to provide information about forest planting, tending of young stands and other silviculture works. The statistics only cover activities financed wholly or partly by the Forest Trust Fund and/or by government subsidies.
Forest area planted or seeded
Forest area planted or seeded for forest production. Does not include supplementary planting.
Number of plants planted
Total number of plants planted. Cover both forest regeneration and supplementary planting.
Planting cost, total
Total cost of plants and planting. Covers both forest regeneration and supplementary planting.
Tending of young stands
Tending of young forest stands until first thinning.
Spot removal of vegetation in order to improve the conditions for natural regeneration and the growth of forest plants.
Productive forest area
Forest area that under favourable stand conditions has an annual yield capacity per hectare of at least 1 cubic metre of wood including bark.

County and municipality level
Microdata are stored in Statistics Norway.
The purpose of the statistics is to provide information at county level about silviculture and forest drainage.
The build-up of the forest administration prescribed in the Forestry Act of 1932 provided a platform for collecting statistical data on silviculture work etc. approved by the Forest Service and was thereby entitled to receive subsidies. Silviculture statistics begin with the fiscal year 1935/36. Before that the Ministry of Agriculture compiled statistics on silviculture, ditch cleaning and fertilizing of forests. The completed figures have been published by Statistics Norway. Statistics on new ditches for forest drainage have previously been compiled entirely by Statistics Norway on the basis of data from the Ministry of Agriculture and Food. Statistics Norway has compiled all silviculture statistics since 1997.
The statistics are used by public agencies (Ministries, County Departments), forest owner's organisations and research institutes. Results from the silviculture statistics are included in the National accounts.
No external users have access to the statistics and analyses before they are published and accessible simultaneously for all users on ssb.no at 8 am. Prior to this, a minimum of three months' advance notice is given in the Statistics Release Calendar. This is one of Statistics Norway’s key principles for ensuring that all users are treated equally.
Results from the Silviculture statistics may be compared with some of the results from the Sample survey of Agriculture and Forestry 2008.
The Statistics Act, §§2-1, 3-2
The statistics only cover activities financed wholly or partly by the Forest Trust Fund and/or by goverment subsidies.
The Forest Trust Fund is a legalised fund where the forest owners set apart a certain amount of the gross value of their roundwood sold. Money from the fund can be used by the owner for forest investments, such as planting, clearing, drainage etc.
The silviculture statistics are based on information from the Norwegian Agriculture Agency and their database on the Forest Trust Fund.
The Forest Service in each municipality keeps the Forest Trust Fund Account. The account is reported to the County Department of Agricultural Affairs (FMLA). The Norwegian Agriculture Agency obtains data from the the Forest Trust Fund databases and organizes them on files forwarded to Statistics Norway.
If the data are unclear, the Norwegian Agriculture Agency or County Department of Agricultural Affairs is contacted so that any errors can be corrected.
Figures based on less than three forest owners are not published if this causes risk for identifying any of the units concerned.
During the period 1935/36-1949/50 the statistics apply to the fiscal year. In 1951 the calendar year was adopted, but the data for this year were combined with the data for the second half of 1950. The transition data from fiscal year to calendar year consequently cover 1 1/2 years. The 1998 figures for Finnmark and 1999 figures for Troms are missing.
In some cases the reported area in the Forest account are estimated. Adaptations to the subsidies system can also occor.
