“…Some investigations have been carried out both on the succession from open water to alderwoods of Alnion glutinosae, which is generally considered as a final successional stage, and also on the further succession towards more drier Alno-Ulmion communities (Fremstad, 1983;Fukarek, 1961;Kollar, 2001;Marek, 1965;McVean, 1956;Neuha¨usl, 1992;Prieditis, 1997a;Szczepanski, 1990). Both routes are initiated by decline in substrate wetness.…”

“…In Lady Park Wood, Gloucestershire, Peterken and Mountford () found the highest density of U. glabra on alluvial soils, a colluvial fan, the rendzinas of upper slopes and on the moist plateau. Although U. glabra is frequent alongside streams, and prefers moist soils across Europe (Brunet, ; Fremstad, ; Hill et al., ; Oberdorfer, ; Tcherepanov, ), it is rarely found in waterlogged areas (Caudullo & de Rigo, ) although it will cope with periodic inundation or variably moist soils (Diekmann, ). In the wettest elm‐ash forests on Öland, Sweden, U. glabra is partly replaced by U. minor (Diekmann, ).…”

Biological Flora of the British Isles: Ulmus glabra

This account presents information on all aspects of the biology of Ulmus glabraHudson (wych elm) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation.2. Ulmus glabra is a large forest tree, and often an important canopy tree in ancient and semi-natural woodlands. It is primarily native to the north and west of Britain and much of mainland Europe. It is the only elm native to Ireland. It is the most distinct of the British elms in that it rarely suckers and sets abundant viable seed.Although found on limestone screes and cliffs, and hedgerows, it is primarily a woodland tree, especially on moist, basic soils. In many secondary woodlands, it often co-occurs with Acer pseudoplatanus and has ecological needs that are similar to Fraxinus excelsior. 3.Ulmus glabra has clusters of c. 25 hermaphrodite flowers appearing before the leaves on previous year's growth. Seeds are wind-dispersed, falling in April to July, but remain viable for only a few days. Nevertheless, seedling establishment can be abundant. Hybridisation with other northern European elms is common but hybrids are notoriously difficult to identify and therefore probably under-recorded.4. The health and survival of wych elm in Europe has been seriously compromised since the 1970s due to Dutch elm disease caused by the fungus Ophiostoma novoulmi, transmitted by elm bark beetles (Scolytus spp.). To the south of its Scottish stronghold, many elms are reduced to small trees regrowing from basal sprouts or seeds. These trees tend to be reinfected once trunk diameter exceeds 10 cm.Fortunately for its long-term survival, seed production usually begins a number of years before they are reinfected.

“…A discussion of population dynamics on the basis of age structure diagrams must necessarily be built on assumptions about the recruitment and mortality of the population studied (Harper 1977). In the case of Alnus glutinosa, the general knowledge about these variables is excellent (McVean 1953, 1955a, b, 1956a, b, c, d, 1959, Trappe et al 1968, Fremstad 1983).…”

The age structure of Alnus glutinosa (L.) Gaertn. populations was studied in two areas on the coast of the Baltic Sea. One area, situated in Upplatid, eastern central Sweden, at 60°07′N, has a relative land uplift of 5.3 mm yr−1; the other area, situated in Blekinge, southeastern Sweden, at 56°10′N, is nearly stable. The spatial distribution of 200 Alnus individuals of various age classes at nine sites was analyzed in order to reconstruct establishment history. In the land uplift area, the youngest individuals were found in the lowest parts of the sites, and age and elevation were significantly correlated. In the area without land uplift, no such pattern was found. Regression analysis of the time/space pattern of establishment in the land uplift area showed that the zone where individuals establish follows the moving shore line with roughly constant speed. Alnus glutinosa uses two different regenerative strategies: (1) continuous colonization of emerging land from seeds (with subsequent mortality of the older trees) in the land uplift area, and (2) regeneration from old stem bases, forming multistemmed trees, in the area without land uplift.
