3.1  Data description

Indicators obtained by statistical surveys are:

Forest land and timber land (in Ha) - by type of ownership and type of management or by forest category

Afforestation and silviculture (in Ha or thousands of pc.) – increase and decrease of land during the year, afforestation by coniferous and non-coniferous species, other cultivation activities, seed and forest tree nursery

Forests species composition (in thousands of Ha) – total tree species area, coniferous and non-coniferous species

Logging and timber deliveries (in thous. m3) – coniferous and non-coniferous logging, processed salvage felling, deliveries of coniferous and non-coniferous species, deliveries of timber wood and fuelwood

Reprivatisation of forests (in pc., in Ha) – applications for restitution of forests by type of ownership

Costs average of selected performances of the main forest activities (in Euro/Ha, Euro/m3) – forest regeneration, silvicultural activities, harvest activities by state forests, non-state forests and total

The selected financial and economic indicators of forest management in the Slovak Republic (in mill. of Euro) – by state forests, non-state forests and total

Degree of forests damage by tree species (in Ha, in %) – damage to coniferous and non-coniferous forests caused by immissions, degree of damage by tree species

3.2  Classification system

Statistical Classification of Economic Activities (SK NACE Rev. 2)

Nomenclature of Territorial Units for Statistics (NUTS)

3.3  Sector coverage

The forestry sector includes basic data on forest land structure in classification by category of forest and by management type, basic data on work in silviculture activities, on regeneration and protection of forests, basic data on logging and timber deliveries.

3.4  Statistical concepts and definitions

Forest land is the land permanently intended to the fulfillment of forest functions. Forest land comprises: a) land covered with forest trees (forests) and the land on which forests were temporarily removed with a view to restore them or with a view to establish tree nurseries, eventually forest seedy plantations; b) land without forests, which serve forestry and are indispensable for him (forest roads, areas  of the forest storages, etc..); c) land above the upper tree vegetation in the high-elevation areas with the exception of built-up land and their access roads.

Timber land includes all lands covered by forest tree species serving for the fulfilment of forest functions and the lands on which the forest stands were temporarily removed with aim of their regeneration or impacting of injurious agent.

Commercial forests are forests, whose main purpose is a production of quality timber while ensuring other roles of the forest.

Protective forests include forest stands with prevailing protective functions. The aim of managing these forest is to guard permanent filling of relevant ecological functions.

Forests for special purposes are forests with specific purpose, which resulting from important specific social demands, that affected way of managing forests.

Land designed for reforestration/afforestation comprises the whole area designed for re-forestation including land taken over to be afforested (former non-forest – mainly agricultural – land). Unsuccessful reforestation increment comprises areas of unsuccessful reforestration in actual years and previous years as well.

Reforestation means really reforestred areas by natural regenerations or by artificial regenerations (seeding or planting). Belong here the areas from first reforestration as well as improvement of existing young plantation which need it.

Logging includes logged mass of wood and mass of wood leave into forest stand in thou-sand cubic metres without bark. We count with all wood mass regardless of type of silviculture or logging interventions it was received, included incidental felling.

Timber deliveries comprise mass of wood in thousand cubic metres without bark, delivered on home market and foreign market and for own consumptions, regardless on place of delivery.
