Impact of changes of the environment and climate on wood formation and wood properties, including dendrochronology
All wood properties relevant for its usability are developed under the influence of natural and anthropogenic environmental factors during its formation in the living tree. Hereby, environmental changes are permanently archived in the wood as long as the tree is living or used as building timber or preserved in the ground for centuries. Such an archive in trees can be used to reconstruct past climate conditions and to predict future modifications in wood structure and eventually wood quality.
At sites with extreme climate conditions such as those close to the tree line in northern Scandinavia trees are reacting more sensitive to climate changes. The research project is aiming at the determination of climate-related variations of wood formation dynamics as well as wood quality.
With microscopic techniques we analyse the growth-ring structures of various tree species as well as with high-resolution monitoring techniques especially for pine trees growing close to the boreal tree line in northern Finland intra-annual cambium dynamics. The results are used to reconstruct past climate as well as to predict future wood formation under different climate scenarios.
