1. Data scope, limitations and quality


The search for websites reporting price information focused on the UNECE region (Europe, North America and CIS) and Asia-Pacific (Australia, Japan and New Zealand). Secondary processed wood products (SPWP) were not considered in this study since these products do not have common international standards regarding specifications and grades. Information sources represent different organization types, ranging from timber merchant to national forest and statistical agencies. Data quality (i.e. correctness, timeliness and usability of data) varies greatly across organization types.

2. Methodology


The metadata schema was an extension of the Dublin Core schema (table 1 below). In addition to the original Dublin Core elements, elements specific to the information needs of forest products price information were added (table 2 below). The extraction of metadata proceeded with an automatic online extraction tool, DC-Dot. Currently, only 12 metadata elements for which complete data is available are shown on each record page.

3. Product and product category

Products and product categories are defined according to the UNECE/FAO/ITTO/EUROSAT JOINT FOREST SECTOR QUESTIONNAIRE (JFSQ). The products of interest included sawlogs, firewood, pulpwood, sawnwood, wood pellets, veneer, plywood, particle board, medium density fiber board, and various grades of pulp and paper. They were grouped under the following headings: industrial roundwood, wood fuel, wood pellets, sawnwood, wood-based panel and pulp and paper. The category wood pellet is an exception to the JFSQ grouping; it is in a category of its own to mark its growing importance in the wood energy sector.
