Webinar February 2021

Title: Variation in albedo and other vegetation traits along gradients of reindeer grazing intensity in Arctic, alpine and boreal regions 

Speaker: Eirik Aasmo Finne, NINA Tromsø and UiO


Reindeers have a great impact on vegetation composition and functioning in large regions of the northern high latitudes. Their effect on ground albedo, i.e. the ratio of reflected to incoming solar radiation, is of particular importance for the surface energy balance and climate. I will present results from the fieldwork last summer to areas in Svalbard and mainland Norway, where we collected ground observations from a range of vegetation types under different reindeer grazing regimes. Emphasis is put on the effect of ground lichen, which contribute to some of the highest albedo values from snow-free ground. Furthermore, the albedo properties will be viewed in light of other relevant vegetation-climate interactions.
