“…3). The significant influence of analogous environmental gradients on structure and composition of this vegetation has already been proven [4,43,44]. In addition to the just-discussed effect of distinctive site conditions, existence of alder forests is also a matter of the recent land use, secondary succession, drainage, melioration and afforestation of permanently wet meadows [45,46].…”

“…Nevertheless, these stands differ in the diagnostic species, physiognomy and habitat conditions at the local scale [24]. The Carici elongatae-Alnetum glutinosae has recently been documented in lowlands and submontane areas of various European countries [4,5,14,15,17,44]. In Poland, plant communities formerly classified within this syntaxon [8,48] were revised by Solińska-Górnicka [11].…”

Variability of alder-dominated forest vegetation along a latitudinal gradient in Slovakia

Syntaxonmical revision of azonal forest vegetation with dominance of Alnus glutinosa and A. incana was done along a latitudinal transect of Slovakia. A data matrix consisting of 240 phytosociological relevés was obtained in accordance with the standard Zürich-Montpellier approach. Detrended correspondence analysis was used to clarify the relationships between the vegetation composition and environmental variables, whereas one-way ANOVA was applied to quantify the differences in site requirements of particular vegetation types. The unsupervised numerical classification resulted in identification of five clusters corresponding to the traditionally described and ecologically interpretable associations within the Euro-Siberian alder carr forests of Alnion glutinosae and the European broad-leaved floodplain forests of Alnion incanae: Carici elongatae-Alnetum glutinosae Schwickerath 1933 (alder carr forests on permanently waterlogged soils), Stellario-Alnetum glutinosae Lohmeyer 1957 (riparian alder vegetation on mesic to humid sites along small brooks), Piceo-Alnetum Mráz 1959 (submontane and montane oligotrophic spruce-alder forests on waterlogged habitats), Cardamino amarae-Alnetum incanae Šomšák 1961 (grey alder vegetation in spring fed areas) and Alnetum incanae Lüdi 1921 (submontane and montane streamside grey alder forests on mesic sites). They significantly (P < 0.05) differed in the Ellenberg's indicator values for nutrients, moisture, temperature and altitude. These environmental variables were also established by DCA analysis as underlying sources of variation in alder-dominated forest composition. Special attention was given to discussion of their syntaxonomy, nomenclature, floristic structure, ecological features and distribution

“…As ash-alder forest is the dominant climax forest community in the studied area of the Mrożyca valley (Matuszkiewicz 2008), as well as in many other areas around the Central European Lowlands (Bodeux 1955, Prieditis 1997, Douda 2008, the ecotones developed on the border between the forest and the river channel (EL) can be considered as reference habitats. The two other investigated types of ecotones, EZ and ER, developed as a result of different types of human impact.…”

The presented study describes the plant species diversity within the terrestrial-water ecotone in relation to the land-use form in a river valley. The study was performed in a lowland river valley where the main forms of riparian zones are partially urbanized, forested and agricultural; the latter being most commonly observed in the investigated region. The present study examines the vascular flora of ecotones where more than 100 plant species were identified. Ecological indices were calculated at all sampling sites based on Zarzycki's ecological values and biodiversity indices. In addition, the aim of the study was to identify the relationships between the physico-chemical parameters of the water and the floristic indicators in the neighbouring ecotones.

“…We used a space-for-time substitution approach by selecting forest stands adjacent to clear-cuts of different age to infer the temporal trends of edge persistence [30]. All studied forest stands are dominated by A. glutinosa and, according to Latvian forest typology, they correspond to Dryopterioso-caricosa and Filipendulosa types which are characterized by wetland forest types on soils with peat layer thickness > 30 cm [31] [25]. Studied forest stands represent over-mature A. glutinosa swamp WKHs with ages ranging from 84 to 129 years (average age 97 years).…”

“…In these forests, the tree layer is dominated by Alnus glutinosa, mixed with Betula pubsecens Ehrh. Some persistent conditions, such as stable microclimate, diverse structural features and mosaic structure with raised hummocks, are important characteristics which provide diverse local conditions with various different niches for many organism groups [25]. Hummocks with a plant detritus layer and overflooding depressions create favorable conditions for diverse and mosaic-type vegetation, rich in hydrophyes, and hygrophytes, and, on the tops of hummocks, typical boreal and shade-tolerant species occur [26].…”

To increase set-aside areas and protect biodiversity values in managed hemiboreal forest landscapes, small forest parcels called Woodland Key Habitats have been designated in Baltic and Nordic countries. The aim of this study was to investigate the persisting influence of the edge on vegetation dynamics for young, medium-old and old edges in Alnus glutinosa (L.) Gaertn. Woodland Key Habitats. All of these edges are adjacent to recently disturbed (clear-cut) stands. We surveyed edge influence on vegetation in bryophyte, herbaceous, shrub and tree layers in 90 plots in 30 set-aside forest stands in Southern Latvia. We tested the differences in the number of species and projective coverage in all vegetation layers, but plant functional types were examined—separately in the herbaceous layer. We found that edge influence in protected forest stands of A. glutinosa swamp forests reflects strong changes in vegetation and plant functional types in the herbaceous layer mostly up to 20 years after clear-cut disturbance in adjacent stands. The greatest differences were between young edges (≤20 years) and old edges (≥41 years), but there were very few significant differences between medium-old (21–40 years) and old edges which signifies more rapid changes in the early stages of edge influence and gradual stabilization of vegetation later on. We found that in edges adjacent to recently disturbed stands (up to 20 years), significantly less rare and indicator epiphytic lichen species occur, but this occurrence increases over time and edge influence is no longer present beyond 20 years after disturbance. Changes in vegetation and species occurrence found in our study indicated the need to plan the allocation of set-aside patches in production forest landscapes to ensure connectivity over longer period of time. Careful planning of clear-cuts in neighboring areas over time can significantly reduce the impact of edge effect on these set-asides.
