Litteraturstudie av veitrafikkstøy og effekter på dyreliv
(NIBIO Rapport, Research report, 2023)Det er behov for en bedre forståelse av hvordan veitrafikkstøy påvirker dyreliv langs vei til bruk i planlegging av veiprosjekter og vurdering av effekten av ulike tiltak for å redusere støybelastning. Vi gjennomførte en ... -
A guideline for material comparisons using LCA
(NIBIO Rapport, Research report, 2023)The materials used in construction have a significant environmental impact and this is becoming more important as operational energy requirements continue to fall. It is therefore becoming increasingly important to take ... -
Økologiske korridorer i landskapsplanlegging ‒ et godt forvaltningstiltak for biologisk mangfold?
(NIBIO Rapport, Research report, 2023)Fragmentering, kontinuitet, konnektivitet og korridorer er begreper som lenge har vært sentrale innenfor landskapsøkologisk teori. Kritiske røster innen fagmiljøet har imidlertid stilt spørsmål omkring de økologiske effektene ... -
Variasjon skaper variasjon – landskapets betydning for landskapets innhold
(Journal article, 2023)Det er velkjent innen økologi at det er en sammenheng mellom variasjon i landskapet og det biologiske mangfoldet. Det er heller ingen hemmelighet at terreng er avgjørende for den geografiske fordelingen av ulike ... -
Taksering av elgbeite, Meråker – oppfølgingstakst 2023
(NIBIO Rapport, Research report, 2023)NIBIO takserte i 2023 elgbeitene i Meråker (om lag 500 km2), for både beitetilbud og beitepress. Busksjiktet var artsfattig, men overraskende produktivt på elgbeite, til tross for nesten bare myr eller skog på låg bonitet. ... -
Årsaker til tidlig hogst: Undersøkelser rettet mot skogeiere, virkeskjøpere og kommunal skogbruksmyndighet
(NIBIO Rapport, Research report, 2023)Når frisk skog avvirkes før den når hogstklasse 5, mens den løpende tilveksten fremdeles er høy, vil dette medføre redusert produksjon av virke og lavere karbonopptak på arealene. Vi har i dette prosjektet kartlagt motivene ... -
Taksering av elgbeite, Levanger – grunntakst 2023
(NIBIO Rapport, Research report, 2023)NIBIO har taksert elgbeitene på 450 km2 i Levanger kommune i 2023. Vi fant at kommunen har et middels godt naturgrunnlag for elgbeite, med nokså høy andel låg bonitet. Per 2023 gir derimot en gunstig alder på skogen mer ... -
Variabelt dekktrykk for tømmerbiler - Effekt på fremkommelighet, vegslitasje og økonomi
(NIBIO Rapport, Research report, 2023)Gjennom prosjektet «Variabelt dekktrykk for tømmerbiler» er et system som gir tømmerbilføreren anledning til løpende regulering av dekktrykket etter hjulbelastning og kjøreforhold testet ut. Videre er det gjort analyser ... -
Country-wide retrieval of forest structure from optical and SAR satellite imagery with deep ensembles
(Peer reviewed; Journal article, 2023-01)Monitoring and managing Earth’s forests in an informed manner is an important requirement for addressing challenges like biodiversity loss and climate change. While traditional in situ or aerial campaigns for forest ... -
An analysis of stand-level size distributions of decay-affected Norway spruce trees based on harvester data
(Peer reviewed; Journal article, 2023-01-05)We studied size distributions of decay-affected Norway spruce trees using cut-to-length harvester data. The harvester data comprised tree-level decay and decay severity recordings from 101 final felling stands, which enabled ... -
Coprophagy in moose: A first observation
(Peer reviewed; Journal article, 2023-01-06)Coprophagy, the eating of feces, has been documented in a wide range of species but appears to be rare or difficult to detect in deer (Cervidae). Here, we report the first observation of coprophagy in moose Alces alces, ... -
Salmon-lice as a potential threat to anadromous Arctic charr populations
(Peer reviewed; Journal article, 2023-01-25)Salmon-lice have the potential to change the behaviour and growth of their salmonid host species. Here, the baseline infection levels of salmon-lice of post-smolts (n = 815) and veteran migrants (n = 875) of sea-run Arctic ... -
Substrate affinities of wood decay fungi are foremost structured by wood properties not climate
(Peer reviewed; Journal article, 2023-02-17)Wood decomposing fungi differ in their substrate affinities, but to what extent factors like wood properties influence host specialization, compared to climate, is largely unknown. In this study, we analysed British field ... -
Building a high-resolution site index map using boosted regression trees: The Norwegian case
(Peer reviewed; Journal article, 2023-03-15)Accurate estimation of site productivity is essential for forest projections and scenario modelling. We present and evaluate models to predict site index (SI) and whether a site is productive (potential total stem volume ... -
Sectoral policies as drivers of forest management and ecosystems services: A case study in Bavaria, Germany
(Peer reviewed; Journal article, 2023-04-07)European countries have national sectoral polices to regulate and promote the provision of a wide range of forest ecosystems services (FES). However, potential incoherencies among these policies can negatively affect the ... -
Climate targets in European timber-producing countries conflict with goals on forest ecosystem services and biodiversity
(Peer reviewed; Journal article, 2023-04-14)The European Union (EU) set clear climate change mitigation targets to reach climate neutrality, accounting for forests and their woody biomass resources. We investigated the consequences of increased harvest demands ... -
Root frost tolerance, seasonal variation in root growth, and field performance of one-year-old Russian larch seedlings with simulated root freezing damages
(Peer reviewed; Journal article, 2023-05-08)Planting healthy seedlings with optimal growth potential is essential for proper growth and survival in forest regeneration. Assessing the seedling quality prior to planting is therefore important. In this Icelandic study, ... -
