Abstract

The interest in dead wood ecology has increased the last years. There have been many studies made on lichens on woody substrates of conifers in boreal forest, but this is the first study on the lichen flora on woody substrate in broad-leaved deciduous forest. In this study the lichen flora was inventoried on 30 decorticated logs of Wych elm, Ulmus glabra in three areas close to Ekoln bay in lake Mälaren South of Uppsala. Totally 36 lichen taxa and one non-lichenised fungus were recorded. According to literature 47 % of these lichen species were earlier not known as lignicolous. The study showed that the number of taxa increased with distance to the log base and decreased with measured log diameter. The highest diversity was found on logs in a stage of intermediate decay. One rare species was present on the logs, Bacidia vermifera.

Under de senaste åren har intresset om ekologin kring död ved ökat. Det har gjorts en hel del studier kring lavar på barrträdsved i boreala skogar, men detta är den första studien av lavfloran på ädellövved. Trettio avbarkade lågor av skogsalm Ulmus glabra inventerades på tre platser vid Mälarviken Ekoln söder om Uppsala. Totalt hittades 36 taxa av lavar och en olicheniserad svamp. Av de funna arterna var enligt litteraturen 47 % inte kända som vedväxande. Antalet taxa ökade med avståndet till lågans bas och minskade med lågans uppmätta diameter. Högst diversitet fanns på lågorna med intermediär nedbrytningsgrad. En ovanlig art hittades på lågorna, nämligen Bacidia vermifera.
