An artificial intelligence approach to remotely assess pale lichen biomass
(Peer reviewed; Journal article, 2022)Although generally given little attention in vegetation studies, ground-dwelling (terricolous) lichens are major contributors to overall carbon and nitrogen cycling, albedo, biodiversity and biomass in many high-latitude ... -
Estimating lichen volume and reindeer winter pasture quality from Landsat imagery
(Peer reviewed; Journal article, 2014)Reindeer and caribou are keystone species in the circumpolar region, and rely on lichens as their main winter forage to survive in some of the most extreme environments on Earth. Lichen mats, however, can be heavily ... -
Feasibility of active handheld NDVI sensors for monitoring of lichen ground cover
(Peer reviewed; Journal article, 2023)Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- ... -
High-resolution modeling of uplift landscapes can inform micrositing of wind turbines for soaring raptors
(Journal article, 2020)Collision risk of soaring birds is partly associated with updrafts to which they are attracted. To ident ify the risk-enhancinglandscape features, a micrositing tool was developed to model orographic and thermal updraft ... -
Linking green infrastructure to urban heat and human health risk mitigation in Oslo, Norway
(Peer reviewed; Journal article, 2019)The predicted extreme temperatures of globalwarming aremagnified in cities due to the urban heat island effect. Even if the target for average temperature increase in the Paris Climate Agreement is met, temperatures during ... -
Literature review of wetland remote sensing and mapping
(NINA Rapport;2014, Report, 2021)Venter, Z.S., Nowell, M.S., Bakkestuen, V., Ruud, A., Kruse, M., Skrindo, A.B., Kyrkjeeide, M.O. & Singsaas, F.T. 2021. Literature review of wetland remote sensing and mapping. NINA Rapport 2014. Norsk institutt for ... -
Local land use associated with socio-economic development in six arctic regions
(Journal article; Peer reviewed, 2018)The socioeconomic causes of land use change are complex. They are highly context dependent, but most often studied through case studies. Here, we use a quasi-experimental paired block design to investigate whether better ... -
Mapping soil organic carbon stocks and trends with satellite-driven high resolution maps over South Africa
(Peer reviewed; Journal article, 2021)Estimation and monitoring of soil organic carbon (SOC) stocks is important for maintaining soil productivity and meeting climate change mitigation targets. Current global SOC maps do not provide enough detail for landscape- ... -
Spatiotemporal variation in the relationship between boreal forest productivity proxies and climate data
(Peer reviewed; Journal article, 2019)The impacts of climate change on high-latitude forest ecosystems are still uncertain. Divergent forest productivity trends have recently been reported both at the local and regional level challenging the projections of ... -
Utvikling av standardiserte bakkesannheter for økosystemer på land
(NINA Rapport;1922, Research report, 2021)Bakkestuen, V. & Venter, Z. 2021. Utvikling av standardiserte bakkesannheter for økosystemer på land. NINA Rapport 1922. Norsk institutt for naturforskning. Miljøforvaltningen har betydelige kartleggings- og overvåkingsbehov. ...
