Kristine Bakke Westergaard

About

Curator of vascular plants Herbarium TRH.

I am eager to integrate field and collection based data with genetic approaches to address fundamental and applied questions in biogeography, systematics and evolution of vascular plants. The tool box is further expanded through collaborations to facilitate interdisciplinary analyses of large data sets including vegetation ecology, soils, invertebrates, satellite data, modelling, bio- and ecoinformatics and AI.

My main research interests are species knowledge, biogeography, historical and contemporary species dispersal, and conservation genetics. I am very interested in alien species, their dispersal pathways and establishment in Norway and the Arctic, horizon scanning and risk assessments. I also focus on arctic-alpine and boreal vascular plants, and am particularly fond of the rare, disjunctly distributed and/or threatened species.

Current projects include:

Detecting unintentional introductions of non-native species to Arctic and Sub-Antarctic islands (NERC, 2026-2028; co-lead)
Red list assessment of Svalbard vascular plants
Conservation translocation and genomics of Eurybia sibirica
Unraveling biogeochemical, microbial and vegetation feedbacks driving soil development and Arctic greening under a warming climate (ETH+, 2021-2026; Collaborator)
Conservation of Biodiversity in China in the light of Climate Change.
Outcome 5 Management measures for selected endangered and invasive alien
species in the context of climate change (2024-2026)
Phylogenomics of Carex sect. scirpinae
Assessing and mitigating the effects of climate change and biological invasions on the spatial redistribution of biodiversity in cold environments (Biodiversa, 2021-2025; WP lead) Home | Asics (coldregioninvasives.com)

I have a PhD (2010) from UiT The Arctic University of Norway, and have worked for 11 years as a researcher at the Norwegian institute for nature research (NINA), where I remain a scientific advisor. Since 2002, I've been responsible for planning logistics, safety, and carrying out botanical expeditions and field work in Norway, Svalbard, Iceland, Scotland, East and West Greenland, Arctic Canada, USA (Alaska, Colorado, Minnesota), Chile and China (Inner Mongolia).
