  1. 1. Hänglavsförekomst i olika kantzoner : En studie i skogarna kring Fällfors, Skellefteå kommun

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

    Författare :Sara Persson; [2023]
    Nyckelord :Epiphytic lichen; Edge effects; Forest fragmentation; Alectoria; Bryoria; Usnea; Canopy opening;

    Sammanfattning : Epiphytic lichens require an even climate (no major changes in temperature and humidity) and continuity in the forest to thrive and grow, but forestry and its clear cutting destroys these habitats. The consequences are particularly serious when it occurs in forests with a high degree of management continuity. LÄS MER
