1. Riskhantering vid naturvårdsbränning : En critical incident studie (CIT)
Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)Sammanfattning : Naturvårdsbränning är en åtgärd som avser att återskapa effekterna avnaturliga skogsbränder genom att påverka det ekologiska systemet. Trotsfördelarna föreligger risker, såsom oönskad eskalering och spridning av eld,rök och glöd, vilket kan negativt påverka mark, människor och samhällen. LÄS MER
2. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

3. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity
Master-uppsats, SLU/Dept. of EcologySammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER
4. Effects of fuel and weather conditions on forest fire behaviour in Southern Sweden in oak dominated forests
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Fire activity is influenced by weather and climate, fuels, ignition agents, and human activities. Fire suppression policy in Sweden resulted in a gradual decrease in the annually burnt areas, changes in fuel loads and a decline in species diversity. LÄS MER
5. Mosippans (Pulsatilla vernalis L.) reaktion på brandstörning : en populationsstudie på en av Sveriges rikaste mosippslokaler
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Spring Pasque Flower, Pulsatilla vernalis (L.) Mill, is a perennial plant which grows in open and sandy pine forests. It is considered sensitive to competition and in need of repeated disturbances. In Sweden P. LÄS MER
