“…Norway spruce is a species becoming less frequent in the tree layer of many forest wetland associations. It has been thanks to such an opening up of the first stand layer (through the appearance of gaps or even whole more extensive open areas) as has been noticeable in several relevés obtained from boreal spruce forest, that light conditions in the forest floor underwent modification leading to an increase in cover in the lower forest layers (Sokołowski, 1999;Grandin, 2004). A source of disquiet from the point of view of the persistence of communities in marshy habitats is the decline in the cover and number of mosslayer species, most especially in communities present on raised bog.…”

“…The falls in light intensity beneath the stand canopy due to increased cover of lower stand layers results from ongoing natural ageing and self-renewal processes (Brewer, 1980;Faliński, 1986;Brunet et al, 1996;Nygard and Odegard, 1999;Grandin, 2004;Økland et al, 2003). Total disintegration of the stand has taken place in many patches of the boreal spruce forest phytocoenosis, in which mass natural renewal of spruce trees has taken place.…”

“…In contrast, since the west coast of Sweden has experienced significant decreases in deposition (Grandin 2011), it has been hypothesized that shifts in ground vegetation species composition there would be related to changes in N and S deposition. In an earlier study of the changes in the understorey vegetation carried out at the Swedish IM catchments, Grandin (2004) found temporal changes in the understorey vegetation, even though understorey vegetation has been shown to respond only slowly to changes in deposition (Strengbom et al 2001;Zechmeister et al 2007).…”

The aims of this study were to investigate spatial patterns and temporal changes in understorey vegetation at four forest catchments forming a depositional gradient. Inventories of the bottom and field layers were carried out in the 1990s and repeated after 5-14 years, depending on catchment. It was hypothesized that changes and patterns in ground vegetation would be related to changes and patterns in N and S deposition. The data were analyzed using Ellenberg indices and multivariate methods. All catchments showed temporal changes in species composition. Analyses of the bottom layer were confounded by a change of field staff, but after accounting for this observer effect, differences in species composition between the catchments remained. Within catchments, the changes in species composition were unrelated to N or S deposition. Relationships between environmental factors, expressed as Ellenberg indices, and compositional patterns differed between catchments although Ellenberg indices showed small temporal changes.

The indicator values are very useful for the description of ecological changes in monitoring studies (Grandin 2004;Samonil and Vrska 2008), for ecological comparison of floristically different areas (Roo-Zielinska 2003) or different management regimes (Dzwonko 2001;Decocq et al 2004).…”

The effect of light conditions on herbs, bryophytes and seedlings of temperate mixed forests in Őrség, Western Hungary

et al. 2009

The effect of light on different understory plant groups (herbs, ground floor bryophytes, trunkdwelling bryophytes and seedlings) was studied in a deciduous-coniferous mixed woodland in Western Hungary. The correlation of cover and species richness in each group and the cover of individual species to relative diffuse light were analyzed at different spatial scales. The study was carried out in 34 forest stands with different tree species composition. The importance of light in determining species composition was investigated by redundancy analysis. Species within each plant group were classified based on their light response. Light was positively correlated with species richness of herbs, cover of ground floor and trunkdwelling bryophytes, and species richness and cover of seedlings. In redundancy analysis, the variance explained by light was 13.0% for herbs, 15.0% for bryophytes and 8.6% for seedlings. Within the group of herbs, species preferring open conditions and light-flexible (gap) species were separated on the basis of the spatial scale of the analysis, while shade-tolerant species were not correlated positively with light. Among bryophytes mainly terricolous, opportunistic and mineral soil-inhabiting species showed significant positive correlations with light, while epiphytic and epixylic species did not respond to light. Seedlings of Quercus petraea and Pinus sylvestris were positively related to light, while most other seedling species were shade-tolerant. In case of vascular plants, the species' correlations with light were in agreement with their light indicator values; however, they were independent in the case of bryophytes. This study proved that the extent and spatial pattern of light influenced strongly the understory plant groups. Species within each group respond to light conditions differently, concerning the strength, direction and spatial scale of the relationships.
