Comparison of estimators of variance for forest inventories with systematic sampling - results from artificial populations
Magnussen, Steen; McRoberts, Ronald E.; Breidenbach, Johannes; Nord-Larsen, Thomas; Ståhl, Göran; Fehrmann, Lutz; Schnell, Sebastian (Peer reviewed; Journal article, 2020-03-23)Background: Large area forest inventories often use regular grids (with a single random start) of sample locations to ensure a uniform sampling intensity across the space of the surveyed populations. A design-unbiased ... -

Also nowadays, the volume of growing stock (GS) is considered one of the most important forest attributes monitored by National Forest Inventories ... -
Harmonisation of stem volume estimates in European National Forest Inventories
Gschwantner, Thomas; Alberdi, Iciar; Balázs, András; Bauwens, Sébastien; Bender, Susann; Borota, Dragan; Bosela, Michal; Bouriaud, Olivier; Cañellas, Isabel; Donis, Jānis; Freudenschuß, Alexandra; Hervé, Jean-Christophe; Hladnik, David; Jansons, Jurģis; Kolozs, László; Korhonen, Kari T.; Kucera, Milos; Kulbokas, Gintaras; Kuliešis, Andrius; Lanz, Adrian; Lejeune, Philippe; Lind, Torgny; Marin, Gheorghe; Morneau, François; Nagy, Dóra; Nord-Larsen, Thomas; Nunes, Leónia; Pantić, Damjan; Paulo, Joana A.; Pikula, Tomas; Redmond, John; Rego, Francisco Castro; Riedel, Thomas; Saint-André, Laurent; Šebeň, Vladimír; Sims, Allan; Skudnik, Mitja; Solti, György; Tomter, Stein Michael; Twomey, Mark; Westerlund, Bertil; Zell, Jürgen (Journal article; Peer reviewed, 2019-02-28)Key message Volume predictions of sample trees are basic inputs for essential National Forest Inventory (NFI) estimates. The predicted volumes are rarely comparable among European NFIs because of country-specific dbh-thresholds ... -
How much water can wood cell walls hold? A triangulation approach to determine the maximum cell wall moisture content
Thybring, Emil Engelund; Digaitis, Ramūnas; Nord-Larsen, Thomas; Beck, Greeley; Fredriksson, Maria (Peer reviewed; Journal article, 2020-08-31)Wood is a porous, hygroscopic material with engineering properties that depend significantly on the amount of water (moisture) in the material. Water in wood can be present in both cell walls and the porous void-structure ... -

Water sorption in wood cell walls–data exploration of the infuential physicochemical characteristics
Fredriksson, Maria; Rüggeberg, Markus; Nord-Larsen, Thomas; Beck, Greeley; Thybring, Emil Engelund (Peer reviewed; Journal article, 2022-12-07)The material properties of wood are intimately tied to the amount of moisture contained in the wood cell walls. The moisture content depends on the environmental conditions, i.e. temperature and relative humidity, but also ... -
