Research forests make it possible to perform long-term experiments and apply silvicultural methods that differ from ordinary forest management methods, serving the needs of forest research.

Field trials play an important role in forest research. They make it possible to monitor the effect of different factors over periods that may extend to decades. When unusual silvicultural treatments or exact monitoring are needed, establishing and managing of sample plots and preserving them undisturbed is often possible only in forests that are specifically reserved for research.

The gained research information and data from the forest site being studied can be used as source information for consequent research projects. The sample plots and sites can also be used as reference sites for dissemination of research data.

	Metla is currently conducting roughly 6,000 field experiments in Finland.

Several experiments and trials have been carried out in series of experiments covering different parts of the country. The oldest trials still being monitored were established in the 1800s. Having detailed information about the history and development of the sample plots provide unique and often unexpected possibilities for research.

The research forests can also serve as grounds where universities and other research organizations can establish their experiments. Metla’s field experiments' contact persons at the Research Units and stations will help in the selection of suitable target areas.
