    • Stand-level growth models for long-term projections of the main species groups in Norway 

      Maleki, Kobra; Astrup, Rasmus Andreas; Kuehne, Christian; McLean, Paul; Antón-Fernández, Clara (Peer reviewed; Journal article, 2022-04-07)
      Stand-level growth and yield models are important tools that support forest managers and policymakers. We used recent data from the Norwegian National Forest Inventory to develop stand-level models, with components for ...

    • Statistikk over skogforhold og skogressurser i Nordland. Landsskogtakseringen 2005-2009 

      Andreassen, Kjell; Eriksen, Rune; Granhus, Aksel; Tomter, Stein Michael; Viken, Knut Ole; Astrup, Rasmus Andreas (Ressursoversikt fra Skog og landskap;01/2011, Research report, 2011)
      Skogarealet i Nordland er dekket av 62 % lauvtredominert skog, hvorav 46 prosentpoeng er bjørkeskog med mer enn 70 % bjørk. Grandominert skog utgjør 29 %, mens 8 % er furudominert skog og 2 % er hogstklasse 1 med uspesifisert ...

    • Tilgang på hogstmoden skog fram mot 2045 

      Granhus, Aksel; Von Lüpke, Nikolas; Eriksen, Rune; Søgaard, Gunnhild; Tomter, Stein Michael; Antón-Fernández, Clara; Astrup, Rasmus Andreas (Ressursoversikt fra Skog og landskap;, Research report, 2014)
      Formålet med denne rapporten er å gi en oversikt over skogressursene som grunnlag for vurdering av avvirkningsmulighetene, med hensyntaken til miljø og driftskostnader, i de neste 30 år. I rapporten gis en oversikt over ...

    • Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data 

      Rahlf, Johannes; Hauglin, Marius; Astrup, Rasmus Andreas; Breidenbach, Johannes (Peer reviewed; Journal article, 2021-05-17)
      Key message Large-scale forest resource maps based on national forest inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs and forest management inventories (FMIs). A comparison of models ...

      Hoffmann, Stephan; Schönauer, Marian; Heppelmann, Joachim; Asikainen, Antti; Cacot, Emmanuel; Eberhard, Benno; Hasenauer, Hubert; Ivanovs, Janis; Jaeger, Dirk; Lazdins, Andis; Mohtashami, Sima; Moskalik, Tadeusz; Nordfjell, Tomas; Stereńczak, Krzysztof; Talbot, Bruce; Uusitalo, Jori; Vuillermoz, Morgan; Astrup, Rasmus Andreas (Peer reviewed; Journal article, 2022-01-08)
      Purpose of Review Mechanized logging operations with ground-based equipment commonly represent European production forestry but are well-known to potentially cause soil impacts through various forms of soil disturbances, ...

    • Tree-Stump Detection, Segmentation, Classification, and Measurement Using Unmanned Aerial Vehicle (UAV) Imagery 

      Puliti, Stefano; Talbot, Bruce; Astrup, Rasmus Andreas (Journal article; Peer reviewed, 2018-02-27)
      Unmanned aerial vehicles (UAVs) are increasingly used as tools to perform a detailed assessment of post-harvest sites. One of the potential use of UAV photogrammetric data is to obtain tree-stump information that can then ...

    • UAV-Based Hyperspectral Imagery for Detection of Root, Butt, and Stem Rot in Norway Spruce 

      Allen, Benjamin James; Dalponte, Michele; Ørka, Hans Ole; Næsset, Erik; Puliti, Stefano; Astrup, Rasmus Andreas; Gobakken, Terje (Peer reviewed; Journal article, 2022-08-08)
      Numerous species of pathogenic wood decay fungi, including members of the genera Heterobasidion and Armillaria, exist in forests in the northern hemisphere. Detection of these fungi through field surveys is often difficult ...

    • Unit-level and area-level small area estimation under heteroscedasticity using digital aerial photogrammetry data 

      Breidenbach, Johannes; Magnussen, Steen; Rahlf, Johannes; Astrup, Rasmus Andreas (Journal article; Peer reviewed, 2018)
      In many applications, estimates are required for small sub-populations with so few (or no) sample plots that direct estimators that do not utilize auxiliary variables (e.g. remotely sensed data) are not applicable or result ...

    • Utviklingsscenarioer for karbonbinding i Norges skoger 

      Astrup, Rasmus Andreas; Dalsgaard, Lise; Eriksen, Rune; Hylen, Gro (Oppdragsrapport fra Skog og landskap;16/2010, Research report, 2010)
      I juni 2009 ble Norsk Institutt for Skog og Landskap bedt om å bistå Landbruks- og Matdepartementet samt Statens Forurensningstilsyn med en analyse av endringene i skogens fremtidige karbonlager under alternative ...
