In terms of wood production, the objective of silviculture is to produce high-quality and economically valuable raw materials in a sustainable and profitable manner. At the same time, the aim is to highlight the importance of forests in the mitigation of the effects of climate change, as well as the ability of forests to adapt to climate change. In addition to wood production, another goal of silviculture is to maintain the viability of forests and their ability to sequester and retain carbon from the atmosphere. Silviculture also aims to secure the biodiversity of forests.

The growth and yield research carried out by Luke aims to study in a comprehensive manner what kinds of effects different factors have on forest growth.  This research is based on valuable data obtained from long-term forest stand experiments lasting up to several decades, which help to investigate the effects of, for example, the tending of seedling stands, thinning method and thinning intensity, growth-enhancing fertilisation, or ditch network maintenance on forest growth.

The growth and yield research carried out by Luke generates information about the silvicultural conditions in Finland and the effects of different silvicultural techniques and combined use thereof on forest growth and harvesting volumes. The research also takes account of the economic feasibility of the measures, as well as objectives other than only those related to wood production. It also provides abundant research data and new tools for use by forest owners, businesses and policy-makers.
