T1. Extent of Forests and Other Wooded Lands

The information on “extent of forests” is necessary for assessment of state and change in forest resources (including goods and services provided by forests) on a global basis. It helps to develop trends of expansion or deforestation of forests and review the sustainability of forests. It facilitates establishing links between national and global classification of extent of forests.

A. Global Classification and Definitions

Forest	Land under forestry or no land use, spanning more than 0.5 hectares; with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ.
Other Wooded Land	Land under forestry or no land use, spanning more than 0.5 hectares; with trees higher than 5 meters and a canopy cover of 5-10 percent, or trees able to reach these thresholds in situ; or with a combined cover of shrubs, bushes and trees above 10 percent.
Other Land with Tree Cover	The lands primarily not under forests having more than 0.5 hectares with a canopy cover of more than 10 percent of trees able to reach a height of 5 m at maturity. It includes trees outside forests.
Other Land	Land not classified as “forest”, “other wooded land” or “other land with tree cover”.
Inland Water bodies	Inland water bodies generally include major rivers and lakes.

2. 2000: According NFI-data for the estimations of Forest and Other Wooded Land.

Other Land with Trees "new introduced" land use class FRA 2005

3. Forest: The Global Classification and definition is “Land under forestry or no land use, spanning more than 0.5 hectares; with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ.” Sweden has instead used... “...all land with a tree crown cover of more than 20 per cent plus half of the land with a tree crown cover ranging from 1 per cent to 20 percent, and area more than 0.25 ha...”. This is due to the fact that the Swedish field inventories have conducted their measurements according to these definitions during the period 1983-1987 and from this period quotients between the different crown cover classes can be used for the present reference period.

4. Other wooded land: The FRA 2005 definition is “Land under forestry or no land use, spanning more than 0.5 hectares; with trees higher than 5 meters and a canopy cover of 5-10 percent, or trees able to reach these thresholds in situ; or with a combined cover of shrubs, bushes and trees above 10 percent”. Sweden will instead use “… a quarter of the land with a tree crown cover ranging from 1-20 % …”, and we will also use areas larger than 0.25 ha and we do not consider the width of the area.

5. Other Land with tree cover: Land with occurrence of trees and not classified as “forest and other wooded land”. The lands primarily not under forestry, spanning more than 0.25 ha* with a canopy cover of more than 10 percent of trees able to reach a height of 5 m at maturity. It includes trees outside forests. *Swedish definition.

6. Following table provides terms and definitions relating to the national presented data sets derived from the Statistical Yearbook of Forestry, for the purpose of illustrating the difference between national statistics and FRA 2005 extracted data.

National land use class	Definition
Forest Land	Land suitable for wood production and not primarily used for other purposes. Potential yield under ideal management conditions at least 1 m3sk (cubic metre standing volume) per hectare and year.
Mire	Peat land without trees or with scattered trees.
Rock Surface	Land without a soil layer or the soil layer too shallow to allow a potential yield of at least 1 m3sk per ha and year. Scattered trees may occur.
Sub Alpine Woodland	Transitional belt between forest land and high mountains with climatic conditions adverse to wood production. Spare occurrence of coniferous trees.
High Mountains	Land at high altitude above the climatic limit for conifer trees. Stunted conifer trees and an abundance of birches of a sub alpine type may occur.
Pasture Land	Agricultural land, not tilled, used for grazing.
Arable land	Agricultural land regularly tilled, used for growing crops or grazing.
Nature Reserves. & Military Wasteland	National parks, other protected areas and certain military areas, not inventoried because of security reasons.
Urban Land	Towns and villages, parks, gardens, nurseries and athletic grounds.
Other Land	Land used for particular purposes and not specified above such as gravel pits, mines, etc.

Comments

In the National Statistical Yearbook of Forestry, area of land-use is described using 10 categories of land use, presented for different regions and the whole country. The sum of all categories of land-use equals the total land area, which is expressed in 1000 ha. The national classes presented are at variance with the FRA 2005 classes. For example, in the national forest statistics of Sweden, forestland is defined according to productivity (vol/ha/yr) and/or designation. According to the FRA 2005 the definition of forest is based on area and canopy cover. In the case of Sweden’s statistics, land with low productivity (less than 1m³/ha/yr) is not classified as forest land regardless whether the canopy cover according to FAO definition would classify the area as forest land.

7. Following table presents national data for national classes defined above. The figures presented are averages of a five year period. E.g., 1990, average (1988-1992).

F. Estimation and Forecasting

Estimation is the process of recalculating national information to the specified reference years 1990 and 2000. Forecasting refers to forecasting the global data for the last reference period 2005. The process of estimation is not needed since data is available for current years. The forecasting for 2005 was made taking into account trends and rounding off figures.

G. Reclassification into FRA 2005 Classes

Reclassification is the process of aggregation or dis-aggregation of original (national) classes into one or many global FRA 2005 variables/classes/categories based on respective definitions and specifications. Sweden does not reclassify data for FRA 2005 reporting tables. The relevant information needed for Global Tables is generated from a direct query to the detailed NFI database.

Comment on the trend

The trend in Sweden over the last 100 years is that the forest area has grown due to the fact of two reasons: 1) large areas of low fertile farm land has either actively or passively been transferred to forest due to better productivity in the agriculture sector; and 2) large areas of other land and other wooded land has been transformed to forest land by draining swamps and low fertile (due to high groundwater levels) land. The exact areas which have been transformed from other land and other wooded land to forest are not possible to give due to lack of records and change in definitions. However, it is probably more than two million ha and less than four million ha. These are rough estimates of gross figures, however if net figures could be presented they would be significantly lower. The reason is of course that forest areas have also been transformed from forest to farmland, both farmland and forest has given their share to public roads and other infrastructure development, etc.

The trends since the 1950s until about 1990 were as for the period above. Since 1990 the active transformation from other wooded land to forest (by draining swamps) has stopped due to nature conservation reasons. Still there is a slow trend in an active transformation of agricultural land to forest.

T2. Ownership of Forests and Other Wooded Land

The information on “ownership” is important for policy, institutional and management purposes. It basically defines the boundaries and location of the authority and control over forest and tree resources.

Global Classification and Definitions

Public Ownership	The ownership of State (national, state and regional governments) or government-owned institutions or corporations or other public bodies including cities, municipalities, villages and communes.
Private Ownership	The right of “ownership” of “Forests” and “Other Wooded Lands” with individuals, families, private co-operatives, corporations, industries, religious and educational institutions, pension or investment funds, and other private institutions.
Other or Unspecified Ownership	The “Other” or “Unspecified ownership” is one that is not classified either as “public ownership” or as “private ownership”.

T3. Designation of Forests and Other Wooded Lands

The information on “designation” or current management objective is essential for development of efficient planning, design and assessment of cross-sectoral impacts, and implementation of forest policy. The “designation” defines boundaries for planned interference in context of the conditions in which “Forests” and “Other Wooded land” reside.

A. Global Classification and Definitions

Production Forest	Forest actually designated for production of forest goods i.e. where the extraction of forest products, usually wood and fibre, are the predominant management objective. It includes both wood and non wood forest products.
Protective Forest	Forests where service of protection to soil and water is the predominant management objective.
Conservation Forest	The “Forests” with predominant management objective of “conservation of biodiversity”.
Social Services Forest	The “forests” where provision of social services (recreation, spiritual, and cultural) is the predominant management objective.
Multiple Objective Forest	The “forests” where a combination of production of goods, protection of soil and water, conservation of biodiversity and provision of social services is the predominant management objective.
Protective “Other Wooded Lands”	The “Other Wooded Land” with predominant management objective of providing service of protection to soil and water.
Conservation “Other Wooded lands	The “Other Wooded Lands” with predominant management objective of “conservation of biodiversity”.
Social Service “Other Wooded lands”	The “Other Wooded Land” with predominant management objective of providing social services (recreation, spiritual, and cultural).
Multiple Objective “Other Wooded lands”	The “Other Wooded Land” where a combination of production of goods, protection of soil and water, conservation of biodiversity and provision of social services is the predominant management objective.

Growing Stock	Volume of all living trees more than X cm in diameter at breast height (or above buttress if these are higher) measured over bark from ground or stump height to a top stem diameter of Y cm, excluding or including branches to a minimum diameter of Z cm. Excludes: smaller branches, twigs, foliage, flowers, seeds, stump and roots.
Commercial Growing Stock	The part of the growing stock of species, considered as actually or potentially commercial under current market conditions, measured above a minimum say “X cm” diameter at breast height. Includes: all potentially commercial (merchantable) species for domestic or international markets.

F. Estimation and Forecasting

Estimation is the process of recalculating national information to the specified reference years 1990 and 2000. Forecasting refers to forecasting the global data for the last reference period 2005. The process of estimation is not needed since data is available for current years. The forecasting for 2005 was made taking into account trends and rounding off figures.

G. Reclassification into FRA 2005 Classes

Reclassification is basically the process of aggregation or dis-aggregation of original (national) classes into one or many global FRA 2005 variables/classes/categories based on respective definitions and specifications. Sweden does not reclassify data for FRA 2005 reporting tables. The relevant information needed for Global Tables is generated from a direct query to the detailed NFI database.

T6. Biomass Stock of Forests

The information on “biomass stocks” is essential to assess the total and the annual capacity of “forests” and Other Wooded Land” to sequester carbon. The annual growth (capacity) defines their sustenance limits of use and management needs and opportunities.

A. Global Classification and Definitions

Above Ground Tree Biomass	The mass, expressed as oven-dry weight (including or excluding bark), of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots.
Below Ground Tree Biomass	The mass, expressed as oven-dry weight of below ground woody parts (includes all roots greater than 2 mm in diameter) of all living trees.
Woody Biomass Stock	The mass expressed as oven-dry weight (including bark) of the woody parts (stem, bark, branches and twigs) of all trees, alive and dead, shrubs and bushes, including stumps, roots, deadwood and litter.

Comments

Volume dead wood -1990 was calculated as volume dead wood -2000 minus difference of volume dry and wind felled trees 2000 and 1990. When calculating dead wood (woody Biomass) for trees > 10 cm d.b.h. the biomass for branches is corrected with -33% for “faster decay”.

Biomass dead wood for trees <10 cm d.b.h. is estimated to app. 20% of biomass dead wood =10 cm; the biomass is corrected with -2.5% for “faster decay” for thin trees.

Biomass in organic debris and branch wood is estimated to app. 1% of “Above Ground Tree Biomass” in “Growing Stock”.
