felloggning

felloggning is a Swedish term used to describe the systematic recording of felled timber and related data during timber harvesting operations. The word combines fälla (to fell) and loggning (logging) and is employed primarily within Swedish and Nordic forestry discourse to denote the documentation phase of harvest activities.

During felloggning, after felling and extraction, crews measure and record attributes for each tree or log. Measurements typically include species, diameter at breast height (DBH), merchantable length, defects, rough volume, and timber grade. The data is linked to spatial coordinates and stand records, enabling accurate inventory updates, yield estimates, and harvest reporting.

Applications and purposes of felloggning include planning and logistics, inventory control, certification compliance, and ecological monitoring as part of sustainable forest management. Accurate data support decision-making on rotation lengths, silvicultural treatments, and market planning while contributing to accountability and transparency in timber flows.

Technology and methods used in felloggning range from traditional tape measures and calipers to scales and GPS devices, often integrated into mobile forest software. Increasingly, data are collected digitally in centralized databases and linked with geographic information systems (GIS) to improve traceability and reporting at landscape scales.

Relation to broader terms: felloggning is related to avverkning (the act of felling) and skogsinventering (forest inventory) but focuses on the documentation stage within harvest operations. It is commonly incorporated into certification schemes such as FSC or PEFC to demonstrate sustainable management and verifiable timber origins.
