Kemera-data includes areas that have been paid Kemera-subsidies. Subsidy can be granted for certain work types in the privately owned forests. Municipalities, state and the majority of companies cannot be granted these subsidies. Subsidy must be applied for before the work has begun. Completion of works must be informed by a separate completion declaration. Applications and completion declarations are processed in the Finnish Forest Centre and saved in the information system according to geographical extents.
