The output of the “Forestry and Logging” sector represents the total value of output produced by all enterprises classified under NACE 02 operating within the territory of the Republic of Bulgaria. A distinction is made between silvicultural output and logging output, as both are separate activities classified under NACE 02 and each has a different principal product. In silvicultural activity, output is recorded progressively as timber stocks increase and is measured by the net annual increment of forests. The value of the net annual increment relates only to forest areas available for wood supply. Output from logging activity is equal the total removals plus the change in inventories of wood in the rough. Output from gathering of wild growing non-wood products includes the gathering of mushrooms, truffles, berries, and etc., but excludes the growing of the same products, which instead are recorded as products of agriculture Services characteristic of the forestry and logging activity services related to planting and thinning, forest inventories, fire protection and etc. The output of the "Forestry and logging" industry also includes the value of goods and services produced from inseparable secondary forestry activities. The "Intermediate consumption“ indicator in „Forestry and logging" sector includes the value of all goods and services used as inputs in the production process, excluding fixed assets whose use is recorded as consumption of fixed capital. These goods and services are processed, or entirely consumed during the manufacturing process. The main components of intermediate consumption are: · Trees, seeds and planting stocks; · Energy, Fuels; · Fertilizers and soil improvements; · Plant protection products; · Maintenance of equipment and facilities; . Maintenance of buildings · Support services to forestry; . Financial services indirectly measured (FISIM) · Other goods and services. Goods and services - intermediate goods are valued at purchase price, operating at the time of their inclusion in the process. The "Value added“ indicator in “ Forestry and logging” sector is the balancing item in the "Production Account" . It measures the value created by еnterprises engaged in forestry and logging activities within the calendar year and is a key element in measuring the productivity of the sector "Forestry and logging". Depending on whether it includes or not includes the value of consumption of fixed capital, it is defined as gross or net value added. The "Consumption of Fixed Capital in Agriculture" measures the wear and tear of aging fixed capital goods. The Consumption of Fixed Capital is calculated for all tangible and intangible fixed assets, improvements to non-produced assets and costs associated with the transfer of ownership. Consumption of fixed capital is not calculated for stocks, work in progress and for non-produced assets such as land, underground deposits and patented assets. The "Income at factor cost“ in forestry and logging sector or "Net value added at Factor Cost" is the value (calculated at basic prices) generated within the calendar year of enterprises engaged in forestry and logging activity, less other taxes on production plus other subsidies on production. Thus, the index measures the remuneration of all factors of production. The "Net Operating Surplus/Net Mixed Income“ indicator measures the yield from land, capital and non-salaried labor in forestry and logging industry. The indicator is calculated by excluding from the net value added the compensation of employees and other taxes on production and adding other subsidies on production. |
