Coastal heathland vegetation is surprisingly resistant to experimental drought across successional stages and latitude
Haugum, Siri Vatsø; Thorvaldsen, Pål; Vandvik, Vigdis; Velle, Liv Guri (Journal article; Peer reviewed, 2021)In the last decade, several major dwarf-shrub dieback events have occurred in northern European coastal heathlands. These dieback events occur after extended periods with sub-zero temperatures under snow-free conditions ... -
Explaining landscape preference heterogeneity using machine learning-based survey analysis
Liu, Xiaozi; Tvinnereim, Endre; Grimsrud, Kristine; Lindhjem, Henrik; Velle, Liv Guri; Saure, Heidi Iren; Lee, Hanna (Journal article; Peer reviewed, 2021)We conducted a national survey on a high-quality internet panel to study landscape preferences in Norway, using photos as stimuli. We examined preference heterogeneity with respect to socio-demographic characteristics and ... -
Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought
Birkeli, Kristine; Gya, Ragnhild; Haugum, Siri Vatsø; Velle, Liv Guri; Vandvik, Vigdis (Journal article; Peer reviewed, 2023)The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ... -
Introducing the index-based ecological condition assessment framework (IBECA)
Jakobsson, Simon; Evju, Marianne; Framstad, Erik; Imbert, Alexis; Lyngstad, Anders; Sickel, Hanne; Sverdrup-Thygeson, Anne; Töpper, Joachim Paul; Vandvik, Vigdis; Velle, Liv Guri; Aarrestad, Per Arild; Nybø, Signe (Journal article; Peer reviewed, 2021)Sustainable nature management and ecosystem conservation depends critically on scientifically sound and stakeholder-relevant analytical frameworks for monitoring and assessing ecological condition. Several general frameworks ... -
Management-driven evolution in a domesticated ecosystem
Vandvik, Vigdis; Töpper, Joachim Paul; Cook, Zoë; Daws, Matthew I.; Heegaard, Einar; Måren, Inger Elisabeth; Velle, Liv Guri (Peer reviewed; Journal article, 2014-02-12)Millennia of human land-use have resulted in the widespread occurrence of what have been coined ‘domesticated ecosystems’. The anthropogenic imprints on diversity, composition, structure and functioning of such systems are ... -
Prescribed burning can promote recovery of Atlantic coastal heathlands suffering dieback after extreme drought events
Velle, Liv Guri; Haugum, Siri Vatsø; Telford, Richard James; Thorvaldsen, Pål; Vandvik, Vigdis (Journal article; Peer reviewed, 2023)Questions During the winter of 2014, an intense drought combined with sub-zero temperatures resulted in a massive Calluna dieback in Norwegian heathlands. We studied the initial vegetation recovery under two management ... -
Reducing Wooden Structure and Wildland-Urban Interface Fire Disaster Risk through Dynamic Risk Assessment and Management
Log, Torgrim; Vandvik, Vigdis; Velle, Liv Guri; Log, Maria-Monika Metallinou (Journal article; Peer reviewed, 2020-03-18)In recent years, severe and deadly wildland-urban interface (WUI) fires have resulted in an increased focus on this particular risk to humans and property, especially in Canada, USA, Australia, and countries in the ... -
Setting reference levels and limits for good ecological condition in terrestrial ecosystems – Insights from a case study based on the IBECA approach
Jakobsson, Simon; Töpper, Joachim Paul; Evju, Marianne; Framstad, Erik; Lyngstad, Anders; Pedersen, Bård; Sickel, Hanne; Sverdrup-Thygeson, Anne; Vandvik, Vigdis; Velle, Liv Guri; Aarrestad, Per Arild; Nybø, Signe (Journal article; Peer reviewed, 2020-09)Effective evidence-based nature conservation and habitat management relies on developing and refining our methodological toolbox for detecting critical ecological changes at an early stage. This requires not only optimizing ...
