1. Produktivitet vid stubbskörd : inverkan av stubbstorlek och avstånd
Kandidat-uppsats, SLU/Department of Forest Biomaterials and Technology (from 131204)Sammanfattning : Sverige står inför en stor klimatomställning och kraven på allt effektivare och miljövänligare energikällor ökar. Biobränslen anses vara en viktig del i denna omställning och stubbved är ett av de primära biobränslena som har stor potential att öka. LÄS MER
2. Stubbrytningens klimatpåverkan : en studie av stubbrytningens kortsiktiga effekter på koldioxidbalansen i boreal barrskog
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Harvesting stumps for biofuel purposes has the potential to reduce the amount of fossil fuel that we use. The climate gain from exchanging fossil- for biofuel can however be offset if the harvesting technique results in higher decomposition rates. LÄS MER
3. Spatiotemporal variation of carbon stocks and fluxes at a clear-cut area in central Sweden
Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Forests have a large role in the global carbon cycle. Forest management could play a crucial role in mitigating climate change. With a growing demand for renewable energy the forest could contribute. Stumps are one of the potential energy sources from the forest. LÄS MER
4. Epixylic, forest-interior bryophytes in young stands : importance of local environmental variables, propagule sources, and distance to bordering woodland key habitats
Magister-uppsats, SLU/Dept. of EcologySammanfattning : The reduction of coarse, dead wood is considered to be the biggest threat to flora and faunain boreal forests. Extensive harvest of logging residues would increase this reduction evenmore. However, the role of dead wood created at final felling for boreal, epixylic species isstill largely unclear. LÄS MER
5. Stubbskörd : från modell till verklighet
Kandidat-uppsats, SLU/School for Forest ManagementSammanfattning : In the near future we need to reduce the greenhouse gas emissions significantly for the benefit of the environment around us. The European Union has de-manded a variety of climate and energy goals to be achieved by year 2020, the “20-20-20” targets. LÄS MER
