BEVARANDE OCH RESTAURERING AV BIOLOGISK MÅNGFALD
Uthålligt skogsbruk har kommit I fokus efter konferensen "Earth Summit I" om miljö och utveckling i Rio de Janeiro 1992. Ett av flera resultat från Riokonferensen är konventionen om biologisk mångfald. Modernt intensivt skogsbruk leder till likåldriga skogar med liten variation, korta rotationsperioder och låg diversitet samt med en dynamik som inte liknar den i naturliga skogar. Tillsammans med fragmentering av kvarvarande skogshabitat och en förlust av skogens naturliga dynamik, t.ex. brand, har detta en negativ effekt på skogens mångfald. Vi måste därför hitta metoder för att minska den negativa påverkan och återskapa naturvärden i våra skogar. Vi studerar ekologin hos enskilda arter, populationer och artsamhällen och utvärderar hur de påverkas av skogsbruk historiskt, i nutid och i framtiden. Den tillämpade målsättningen med vårt arbete är att utveckla metoder som minimerar negativ påverkan på den biologiska mångfalden samt utveckla metoder för att återställa naturvärden i påverkade skogar.
FOREST BIOCORE
FOREST BIOCORE är en grupp av forskare vid institutionen för vilt, fisk och miljö SLU-Umeå, samt institutionen för ekologi och miljövetenskap, Umeå University. Gruppen arbeter tilsammans med associerade forkare med frågor som rör Biodiversitet, Bevarande och Restaurering (BIOdiversity, COnservation and Restoration) i huvudsakligen boreala skogslandskap.
