Abstract

Regeneration with scarification and planting is a well known method, but the plants have a tuff period in the beginning. Decease of plants comes from pine weevils, dry weather, browsers, wrong method of scarification and wrong time for the planting. These are some courses why not every planting gets successful. The purpose with this study is to investigate witch time of planting gives the best result, spring or autumn planting and to give a answer of witch factors are the main course of deceases. The goal is to have the study to decide witch time to plant after final felling. The choices of plantings were maid from a period of three years. Spring plantings were from year 2005, 2006 and 2007 and autumn plantings were from 2004, 2005, and 2006.The purpose was to compare differences in deceases at the same spring weather. Autumn plantings 2004 were compared with spring plantings 2005 and so on. An equal distribution aimed at clear cut areas witch have been scarification with harrow and excavator. The clear cut areas should also have low site index. The planting areas were objective surveyed in grids. On every sample plot assessed the number of living, dead and injured plants. In this study the result shows that both autumn and spring plantings have an acceptable regeneration result. Nothing interprets that time of planting have a significant sense for the regeneration result. Conclusions of this study are that both spring planting and at autumn planting give an acceptable regeneration result. A way to reduce deceases and damages from pine beetle can be to let the clear cut areas rest for three years before planting. To reduce damages made from wild can plants be treated by some of the preparations blood flour, PV-wild protection, Cervacol Extra or Cervaroll. In this study shows that scarification with excavator give a stable result compared with scarification with harrow as gave some inferior regeneration results. Ones and again maybe the harrow scarification clear cut areas can rest for three years before planting. That can reduce attacks from pine beetle.
