1. Degradation and restoration method interact to affect the performance of planted seedlings in tropical rainforest restoration : evidence from plant functional traits
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Ecology and ManagementSammanfattning : A common action to improve or save biodiversity in the tropics is restoration of degraded rainforest. To understand the complex ecological structures of the forest and adapt the restoration actions after them, studies have focused on characterizing species with functional traits. LÄS MER
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 ManagementSammanfattning : 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.

3. Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Tropical rain forests only cover around six percent of the world’s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity. LÄS MER
4. 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 ManagementSammanfattning : 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
5. Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet
L3-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned.
