  1. 1. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER

  3. 2. Strengthening green infrastructure : modelling connectivity between continuity forests with high nature conservation values at the Sveaskog forest holding in northern Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Simon Mattsson; [2022]
    Nyckelord :betweenness centrality; connectivity; forest biodiversity; graphab; graph modelling; high conservation value forest; proxy continuity forest; qgis;

    Sammanfattning : The continuity forests of the Swedish boreal landscape have become very sparse due to intensive rotation forestry and human land-use, and the remaining forests are very fragmented. These forests have a high conservational importance as they hold nature values that relies on a long forest continuity. LÄS MER

  4. 3. Explaining population size of the saproxylic beetle Prionus coriarius as a function of available dead wood resources

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Isak Sarac; [2016]
    Nyckelord :pheromone; coleoptera; cerambycidae; dispersal; threshold; conservation;

    Sammanfattning : Dead wood is an important substrate for many forest bound species including the large group of dead wood associated (saproxylic) beetles. Saproxylic beetles have species specific substrate requirements, that may vary according to factor such as tree species, object type, trunk diameter and decomposition stage. LÄS MER

  5. 4. Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?

    L3-uppsats, SLU/Dept. of Forest Products

    Författare :Emil Andersson; [2006]
    Nyckelord :kontinuitetsskogsbruk; mångbruk; alternativa skogsbruksmetoder; skogsbruk; Norden;

    Sammanfattning : Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. LÄS MER
