… area is covered with shallow or thick peat. There is a potential to increase forest production in Sweden with almost 2 million m3/year in selected peatlands with low conservation values. This increase can be accomplished by drainage, complementary drainage, ditch maintenance …
I Sverige bedrivs skogsbruk på en stor del av skogsmarken vilket riskerar att påverka miljön i vattendragen negativt. Lokala utströmningsområden i anslutning till vattendrag har extra stor betydelse för ytvattnets kemi. Störningar i utströmningsområden, såsom körskador och …
Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are …
Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry …
