Background

Even-sized (low-thinning) forest management method is

considered to be the most productive and profitable silvicultural practice. However, recent studies have shown that even-sized forests do not always convey the expected productivity and profitability.

Climate change, environmental protection, multiple-use of forests and land-use disputes all affect sustainability of raw wood-material production.

Information on sustainable supply of raw wood materials by assortments (i.e., sawn wood, pulp wood, firewood and energy wood) and by species is essential for traditional and new forest clusters (i.e., pharmaceutical, chemical and biotechnology

industries).

In addition, more information is needed to evaluate the

sustainability of energy production from energy wood and the impact of energy wood utilization on forest ecosystem,

How alternative (different) forest management

systems can be used to cope with the transition of traditional forest clusters and their

socio-economic implementations?

What are the potentials of alternative (different)

forest management systems to meet the needs for sustainable production of raw wood material as well as maintaining forest ecosystem functions?

Maintaining equilibrium of forest population dynamics (i.e. growth, mortality and reproduction) is essential to ensure sustainable forest productivity.

Appropriately introduced competition effects via forest

management can increase resistance to abiotic (i.e., storm and draught) damages to forest growth, structure, and productivity.

Uneven-aged forest management systems are environmentally friendly and they increase sustainability in forest productivity.

The restructuring phase of the forest industry cluster will lead towards uneven-aged forest management systems due to

changing demand conditions and changes in competitiveness.

The socio-economic impacts of the implementation of uneven-aged forest management systems are significant at regional and local scales leading to pressures in spatial and social structures and infrastructure.

We need to develop statistical models and simulation software using high performance computing techniques for testing the these hypotheses.

changing climate conditions, and using the models for spatio-temporal simulations.

dynamics under even- and uneven-aged forest management systems and their significance in sustainable timber supply.

Expected results: Geography

An analysis of forest sector and forest related socio-economics development in Finland.

Case studies of the impact of transition from

domestic production to foreign investments in the forest sector on socio-economics.

Risk/benefit analysis of alternative forest

management systems on sustainable raw wood material supply.

Expected results: IT

HPC software and computer codes to be published

under open source license. While in other areas of natural sciences (physics, chemistry, etc.) software repositories are abundant, these are still lacking in forest ecosystem simulations and hence this project constitutes a significant development towards such open source repositories.

Applications of High Performance Computing (HPC)

techniques in large-scale forest ecosystem

simulations. The SUSWOOD project represents a major step forward in utilizing HPC techniques in forest ecosystem simulations.
