1. 1. Hur påverkar tillgången på ljus höjdtillväxten hos planterade regnskogsträd i en sekundär regnskog på Borneo?

   Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Emmy Dieden; [2015]
   Nyckelord :ljus; höjdtillväxt; sekundär regnskog; pionjärarter; klimaxarter; skogsrehabilitering;

   Sammanfattning : Regnskogen på Borneo är en av de artrikaste i världen men till följd av mänsklig aktivitet, såsom avverkning, har dessa ekosystem drabbats hårt. Naturlig återhämtning är svår då dessa störningsdrabbade områden missgynnar arter som tillhör områdets naturliga flora och därför finns det ett behov av aktiv rehabilitering av dessa skogar. LÄS MER

3. 2. Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Sara Waern; [2015]
   Nyckelord :skogsbrand; selektiv avverkning; Dipterocarpaceae; assisterad naturlig föryngring ANR ; forest fire; selective logging; Dipterocarpaceae; assisted natural regeneration ANR ;

   Sammanfattning : Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation.

4. 3. Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Malin Boström; [2015]
   Nyckelord :näringsbegränsning; penetrationsmotstånd; bulkdensitet; jordegenskaper; trädtillväxt; nutrient limitation; penetration resistance; bulk density; soil properties; tree growth;

   Sammanfattning : The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. LÄS MER

5. 4. The effects of mother trees and site conditions on the distribution of natural regeneration establishment in a Bornean rainforest disturbed by logging and fire

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Ecology and Management

   Författare :Sebastian Backlund; [2013]
   Nyckelord :Dipterocarpaceae; Dipterocarps; dispersal; mother trees; natural regeneration; site factors; tropical rainforest; Dipterocarper; moderträd; naturlig föryngring; spridning; ståndortsfaktorer; tropisk regnskog;

   Sammanfattning : In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. LÄS MER

7. 5. Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia

   Magister-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Viveca Luc; [2010]
   Nyckelord :artificial gaps; Borneo; Dipterocarpaceae; forest degradation; forest fire; forest rehabilitation; liberation;

   Sammanfattning : Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. LÄS MER
