Temperate broadleaved forests are one of the most anthropogenically disturbed biomes and especially old natural forests have become rare. It is widely acknowledged that in addition to global and landscape scale factors, disturbance history, forest management and ecological continuity affect structural diversity in a forest and hence, species richness. Many species groups are however, poorly studied and it is not completely understood which are the main factors affecting species richness in a forest stand and what finally causes the extinction of a population. I studied temperate broadleaved forests in Denmark and aim of my study was to investigate what are the different elements in forest stand structure affecting the species richness of wood-inhabiting fungi, epiphytic lichens and bryophytes. I also tested whether ancient forest plant species or local indicator species could be used as an indicator group for estimating the species richness of these three species groups. Or whether some of the elements in a forest stand structure could be used as a structural indicator for species richness in the area. The data was collected from a nature reserve called Lille Vildmose, in North Jutland, Denmark, during 2013-2014. I used Analysis of Covariance to analyse which of the factors in stand structure correlated with the species richness of epiphytic lichens, epiphytic bryophytes and wood-inhabiting fungi and Pearson correlation to test the correlation between the occurrence of my study species and potential indicators. Stand age, average water level and basal area of broadleaved trees were the most significant factors correlating with the species richness of epiphytic lichens. Species richness of living trees, basal area of broadleaved trees and stand age correlated significantly with the species richness of epiphytic bryophytes. And dead wood volume, number of dead wood tree species, stand age and average dead wood diameter correlated significantly with the species richness of wood-inhabiting fungi. The results were consistent with several previous studies and showed that old forest stands and high volume of dead wood are essential factors in maintaining species richness in temperate broadleaved forests. The correlations between the occurrence of ancient forest plant species and my study species were not significant enough that ancient forest plant species could be used as indicator group for the study species. Also the correlations between the occurrence of local indicator species and my study species were too weak that local indicator species could be used as indicator group for the study species either.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Meeri V\u00e4\u00e4t\u00e4inen (mesisava) on 2015-06-09 09:52:29.224130.
