Forest act changed a little in 2014. Forest owners have more opportunities to take care of their own forest. Since 2014 it is possible to manage forest with of different age structure. Different age structure means that the forest includes trees of all stages of development. Reforestation is done naturally. Clearcutting is not needed. Forest area is always covered by all ages of development trees. Different age structure is handled at picking harvesting and small range logging. In picking harvesting you pick trees like trees were individuals. In this way law does not oblige to plant new trees. Small range logging is also used at same age structure forests. Small hole logging open sunlight and space of living and growing for saplings. Switch over to different age structure of grown forests has to plan individually. Different age structure of growing forests sup-ports the diversity of the forest, the potential money savings trees planting and if forest are used for some outdoor interests. Viability of different age structure forest raise if it is possible to sell trees in small amounts. Advocates of same age structure forest are clear precepts how to take care of forest, it is assured trees planning, planted trees grown faster, long term guarantee, easy keeping and viability. There are no big risks to try different age structure of taking care of forest. The reason for minimal risk is easy to return to same age structure by clear cutting the forest. The only thing what may be lost is a couple of growing seasons. Forestry professionals have opinions for and against different age structure. This thesis includes real test pattern where accomplish picking harvesting and small range logging.
