“…Schnitzler, 1994Schnitzler, , 1995Schnitzler, , 1997Wolf et al, 1997;Decocq, 2002) suggest that the results of the charcoal and seeds identifications results in a fairly complete image of the taxonomic composition of the woody vegetation on the sand ridges. Acer pseudoplatanus, Fagus sylvatica and Carpinus betulus, species that now sometimes occur on the highest elevations within alluvial hardwood forests have not been found.…”

“…The high diversity of light demanding shrubs at the sites of Doel however can most probably be explained by the nature of the natural vegetation itself at these sites, as current alluvial hardwood forests generally do show a larger abundance in both shrubs and lianas. This is explained by the unevenness in the canopy, coupled with the small size of the leaves, favoring light penetration to trunk and ground level (Schnitzler, 1994).…”

“…hardwood alluvial forests (German: HartholzAuenwald), which are phytosociologically assigned to the Alno-Ulmion and more specifically the QuercoUlmetum Issler 1924. These are considered to be one of the most productive and species-rich of temperate forest ecosystems (Carbiener, 1970;Grubb, 1987;Schnitzler, 1994). These forests occur under specific hydrodynamic conditions i.e.…”

“…These forests occur under specific hydrodynamic conditions i.e. on areas within the river floodplain that are only incidentally touched by inundations of short duration (Schnitzler 1994;Wolf et al, 1997). The frequency of these inundations ranges from one time every few years to a few times in one year.…”

“…Based on the ecological characters of the trees and shrubs that have been found, especially their tolerance to high groundwater levels and seasonal flooding (e.g. Ellenberg, 1988;Schnitzler 1994Schnitzler , 1995, the geomorphological position of the sand ridges (e.g. on the valley bottom of the lower Scheldt River), the presence of the clayey deposits surrounding the sand ridges which show a similar age as the occupation period, and the presence of a brunified soil on top of the sand ridges (Louwagie & Langohr, 2005), a more detailed environmental reconstruction can be made however (fig 5).…”

The analysis of a large number of charcoal fragments from fire places from a wetland camp site of the Mesolithic-Neolithic transition period (Swifterbant culture) now permits a detailed reconstruction of a middle Holocene riverine forest along the Lower Scheldt River (northern Belgium) and its exploitation between ca. 4,500 and 4,000 BC. The identified taxa point towards an alluvial hardwood forest (Querco-Ulmetum minoris Issler 1924) on the sand dune on which the camp site was situated, surrounded by alder carr. The results are compared with palynological and macrobotanical analyses from the same site and from contemporary sites within the area; the complementarity of these different types of data is discussed. The combination of all these datasets results in a detailed reconstruction of the environment and of its exploitation by the Swifterbant culture. The results also show that the Swifterbant people not only depended on these sand ridges for dry settlement locations, but also for firewood collection, gathering of edible plants and most probably for the collection of leaf fodder to feed livestock during winter time.

1. Riparian forests, because of their multiple ecological and dynamic functions, have become a subject of particular interest for managers. This is the case in France following the Water Law of 3 January 1992 and the development of the ‘Schéma Directeur d'Aménagement et de Gestion des Eaux (SDAGE)’ (Planning and Management—Master Plan—of Water Resources) in various sub‐catchments of the Rhône. Within this framework, the major themes of ecologically integrated riparian forest management have been developed on a 110 km section of the Drôme river, a piedmont tributary of the middle Rhône river, in south‐eastern France. 2. The geographical expansion, diversity and evolution of riparian forest within this section of the Drôme since 1948 have been studied. The transport of woody debris, which is characteristic of forest hydrosystems, has also been taken into consideration as managers were concerned by its recent increase. 3. The recently developed vegetation corridor, measuring nearly 710 ha, is threatened by reduced bedload availability leading to channel incision and the disconnection of the floodplain from the active band of the channel, as well as reduced vegetation renewal. 4. Several management proposals have been put forward in an effort to maintain riparian ecosystem dynamics without simultaneously increasing flooding and erosion risk: (i) legal measures to conserve the most functional sections, (ii) replanting a vegetation corridor at least 5 m wide in farming areas, (iii) impeding the breaking‐up of the most interesting vegetation corridors into small parcels of land, (iv) urgently encouraging the regeneration of vegetation margins and renewed sediment transport, namely by creating artificial overflow channels in forested areas or by clearing certain sectors of the active channel. 5. It has been proposed that vegetation maintenance and logjam removal, today recognized as detrimental from an ecological standpoint, be conducted selectively on the basis of management appraisals of certain sectors. Certain reaches will no longer be subject to maintenance on the grounds of their great ecological value and because of their low risk of flooding impacts. ©1997 John Wiley & Sons, Ltd.

Insights into the Vitis complex in the Danube floodplain (Austria)

European grapevine populations quickly disappeared from most of their range, massively killed by the spread of North American grapevine pests and diseases. Nowadays taxonomic pollution represents a new threat. A large Vitis complex involves escaped cultivars, rootstocks, and wild grapevines. The study aimed to provide insight into the Vitis complex in the Danube region through field and genetic analyses. Among the five other major rivers in Europe which still host wild grapevine populations, the Danube floodplain is the only one benefiting from an extensive protected forest area (93 km²) and an relatively active dynamic flood pulse. The Donau‐Auen National Park also regroups the largest wild grapevine population in Europe. Ninety‐two percent of the individuals collected in the park were true wild grapevines, and 8% were hybrids and introgressed individuals of rootstocks, wild grapevines, and cultivars. These three groups are interfertile acting either as pollen donor or receiver. Hybrids were established within and outside the dykes, mostly in anthropized forest edges. The best‐developed individuals imply rootstock genes. They establish in the most erosive parts of the floodplain. 42% of the true wild grapevines lived at the edges of forest/meadow, 33.3% at the edges forest/channels, and 23.9% in forest gaps. DBH (Diameter Breast Height) varied significantly with the occurrence of flooding. Clones were found in both true wild and hybrids/introgressed grapevines. The process of cloning seemed to be prevented in places where flooding dynamics is reduced. The current global distribution of true wild grapevines shows a strong tendency toward clustering, in sites where forestry practices were the most extensive. However, the reduced flooding activity is a danger for long‐term sustainability of the natural wild grapevine population.
