SUMMARY Summary 1 The production of forestry statistics Jan-Olof Loman The Statistical Yearbook of Forestry outlines a comprehensive, clear and accessible account of important forestry statistics in Sweden. Each chapter in this English summary includes results and a description of the sources. The Yearbook consists of 16 chapters Chapter 1 Description of forest statistics Chapter 2 Estate and ownership structures Chapters 3–5 Description of forest resources, environment and damage Chapters 6–7 Forestry activities Chapters 8–9 Transportation and stocks Chapters 10–11 Use of roundwood Chapters 12–14 Labour force and economic data Chapters 15–16 Foreign trade and international data The Swedish publication also includes: • List of contents in Swedish and English. • Figures and tables in Swedish and English. Most data are from 2004 and sources are presented under the heading “Källhänvisningar” in each chapter. Figures and tables are also referenced. Appendix 5 (bilaga 5) includes addresses for referenced organisations. Editors can be contacted at: firstname.familyname@skogsstyrelsen.se (å, Å=a; ä, Ä=a; ö, Ö=o) The information in tables and figures is available in Excel documents and an English language version is presented on the website. The icon identifies certified official statistics. These statistics are produced and published in accordance with Swedish legislation. The Official Statistics Act ensures public access to statistical information. Public authorities are responsible for making readily available, objective information that can be accessed free of charge. Planning and research requirements are also to be met. Furthermore, statistics are to be produced and published in a manner that protects the privacy of individuals. The three most important producers of official forestry statistics are the Swedish Forest Agency, the National Forest Inventory (at the Swedish University of Agricultural Sciences) and Statistics Sweden. The Swedish Forest Agency is since 1 January 2006 the name of the former National Board of Forestry and the ten Regional Forestry Boards. It is a united governmental agency, consisting of a main office, five regions and some 45 districts covering the entire country. The Swedish Forest Agency is, among other tasks, responsible for producing official statistics on employment and production in the forestry sector. 305
SUMMARY Employment research illustrates a diversity of scales in the forestry sector, including: large-scale producers, forestry contractors and private forest owners. Production research is a multi-level task. The Swedish Forest Agency is responsible for compiling silviculture statistics and forestry production costs, including prices for roundwood as well as prices for stocks of logs and chips. The Swedish Forest Agency also calculates gross felling and removal on an annual basis. The National Forest Inventory (NFI) is an all-encompassing annual inventory of Swedish forests. The objective is to provide basic data for research, planning and control of forest resources at a national and regional level. The NFI reports on forestry resource change and land use change. The Department of Forest Resource Management and Geomatics at the Swedish University of Agricultural Sciences (SLU) is responsible for the NFI. Beginning in 1923 the inventory gradually progressed to cover the entire country by 1953. The annual sample cover some 12,000 circular plots, of which 6,000 plots are on forested land. The inventory is based on permanent and temporary plots with a radius of 10 and 7 meters respectively. Permanent plots are revisited by 5 to10 year intervals, allowing for an effective estimation of change. The following research observation categories are used for the entire inventory: land use, ownership, growing stock, growth, tree distribution and recent felling. Observations on forested land also include: terrain conditions, vegetation cover, maturity class, age, site quality, recent and suggested silvicultural measures, the degree of stocking damage and regeneration status in young stands. NFI results are in most cases unbiased, but may have significant sample errors. To secure a good precision for the estimates usually mean values from several years is used, generally a 5 year period. Here follows a list of commonly used variables in the NFI and their definitions: Forest land – Land suitable for wood production and not primarily used for other purposes. Potential yield under ideal management conditions at least 1 m 3 sk (cubic metre stem volume over bark from stump to tip) 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 m 3 sk per hectare and year. May contain scattered trees. Sub alpine woodland – Transitional belt between forest land and high mountainous terrain 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 sub-alpine birches common. Pasture land – Agricultural land, not tilled, used for grazing. Arable land – Agricultural land regularly tilled, used for growing crops or grazing. Nature reserves and 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 areas – Land used for particular purposes and not specified above, such as gravel pits, mines, etc. The State – State owned forests. Other public owners – Forests owned by the church, municipalities, public foundations or other public institutions. Companies – Forests owned by limited companies whether private or public, like SCA, Stora Enso etc. Private citizens – Forests owned by private owners other than limited companies such as farmers, private mansion estates etc. Statistics Sweden bears the overall responsibility for co-ordinating and supervising official statistics in Sweden. They are responsible for statistics in social fields such as the labour market, economy, trade and industry, population and welfare or housing and construction. This information is highly valuable to the forestry sector. Statistics relating to industrial production; raw material consumption; international forestry trade; transportation logistics; and stocks of timber, chips and sawn wood are particularly interesting to the forestry sector. The data is generally presented by county or 306
