Abstract
Coniferous as spruce (more specifically Norway spruce, Picea abies) and deciduous
species like European beech (Fagus sylvatica) and oak (Quercus spp.) co exist in south
Sweden. In perspective of climate change, species composition of Swedish forests is
assumed to change.
Observed climate on the period 1950-2010 prove that a general warming trend is
occurring in southern Sweden, and that vegetation growth period is getting longer.
From the observed weather data, annual precipitation and minimum temperature in
spring are highlighted in order to analyse the response of the three tree species.
Extreme years are distinguished.
Responses from the trees are studied in terms of onset and end of vegetation period
and length of vegetation... (More)

From the observed weather data, annual precipitation and minimum temperature in
spring are highlighted in order to analyse the response of the three tree species.
Extreme years are distinguished.
Responses from the trees are studied in terms of onset and end of vegetation period
and length of vegetation period, for each species, using observations from satellite data
(MODIS) for the period 2000-2009. Variations observed during extreme years constitute
the basis for an interpretation of the species-specific response to climate events,
qualified as stressful for the vegetation.
Further on, the discussion is relating stressful weather events with tree defence capacity
and biotic stresses (e.g insect outbreaks) and their role in a disturbance system. Links to
forest ecosystem are made through processes like regeneration, competition and
migration. Climate change projections are analysed in order to study the potential
reactions of the three species in South Sweden with climate shifts according the
observations made in the previous parts. (Less)
