“…From this report, it became obvious that national forest inventories had a great po ten tial to be key sources of information. Later this was confirmed by, e.g., Cienciala et al (2008), Dunger et al (2012) and GFOI (2014).…”

• National Forest Inventories supply invaluable long term time series of forest state. Recent developments and international harmonization of modern NFIs widen the scope to even include ecosystem goods, e.g. biodiversity and carbon sequestration. The combination of NFI field data with remote sensing techniques can give good estimates for areas smaller than national and regional level. AbstractNational Forest Inventories (NFIs) are becoming increasingly important worldwide in order to provide information about the multiple functions of forests, e.g. their provision of raw materials to industry, biodiversity and their capacity to store carbon for mitigating climate change. In several countries the history of NFIs is very long. For these countries a specific challenge is to keep the inventories up-to-date without sacrificing the advantages associated with long time series. At the turn of the 20th century European NFIs faced some major challenges. In this article we describe the history and the recent developments of the Swedish NFI as an example from which general observations are made and discussed. The Swedish NFI started in 1923 and has evolved from an inventory with a narrow focus on wood resources to an inventory today which aims to provide information about all major forest ecosystem services. It can be concluded that the traditional approaches of most European NFIs, e.g. to collect data through sample plot field inventories, has proved to be applicable even for a wide range of new information requirements. Specifically, detailed data about land use, trees, vegetation, and soils has found new important uses in connection with biodiversity assessments and the estimation of greenhouse gas emissions. Though time-consuming and difficult, making NFI information comparable across countries through harmonization appears to be a useful approach. The European National Forest Inventory Network (ENFIN) was formed in 2003 and has been successful in pan-European NFI harmonization.

“…However, in reality different methods or emission factors are adopted for different pools (e.g. Dunger et al 2012) and thus differences in definitions are likely to affect the final estimates of total emissions. Furthermore, Herrmann and Bauhus (2013) suggest that it is too simple to model carbon emissions with constant decay rates and instead the decay stage of dead wood should be taken into account.…”

A survey was conducted to assess the impact of the choice of definition on reported quantities of dead wood in Swedish forests, which to more than 90% are located in the boreal zone. The data collection was made on a subsample of the permanent plots of the Swedish national forest inventory. The objects included were standing dead trees and snags down to 5 cm diameter at breast height, dead lying stems and branches down to a threshold diameter of 1 cm, and stumps down to a threshold diameter of 5 cm at normal stump height. Standing trees, snags, and stumps were inventoried on 10 m radius circular plots while the downed objects were inventoried using both circular plots and line intersect sampling; thin objects (diameter 1-5 cm) were assessed only through line intersect sampling. The results showed that the estimated volume of dead wood was as high as 25 m 3 ha -1 when all components were included. With the standard Swedish definition, the corresponding estimate was only 10.9 m 3 ha -1 , or 43 % of the total value. Since definitions of dead wood vary greatly between countries we conclude that great caution must be exercised when figures are compared in connection with international reporting. For example, adding stumps to the Swedish definition would increase the amounts of dead wood from 10.9 m 3 ha -1 to 15.7 m 3 ha -1 , i.e. with 44 %.

“…The study established common definitions for NFIs for the distinction of trees from shrubs, provides a hierarchical partitioning approach by which the whole tree is stepwise divided into disjoint and defined tree parts, and specifies variables like tree height, stem length, dbh, crown and crown projection area, and tree characteristics regarding life status, standing status and tree shape. -Greenhouse Gas Reporting from European Forests (Dunger et al 2012). This study is based on case studies of Finland, Germany, Norway, Portugal, Slovenia, and Sweden.…”
