Summary

This is riparian woodland occurring on periodically-inundated river terraces of active floodplains with deposition of nutrient-rich alluvium in the boreal, boreo-nemoral, nemoral, submediterranean and steppe zones. Typically, there is a tall canopy dominated by one or a few tree species, commonly Salix alba, sometimes S. fragilis (maybe favouring situations where there is lime-deficiency). Two other trees commonly found here are Populus alba which is really a submediterranean tree but widely planted and naturalised and P. nigra, native in a large part of Europe (from western to central south-eastern part), but also widely planted, though often outnumbered there by hybrids such as P. x euramericana and x canadensis. Typically, alder is absent from the canopy and riparian woodlands where Alnus glutinosa or A. incana form part or all of the tree cover are not included here but with land-upheaval woodlands in G1.2a Alnus woodland on alluvial and mineral soil. There is often a dense understorey of smaller Salix spp., Sambucus nigra and other shrubs beneath the trees, the composition of this layer depending on the local degree of wetness of the ground. Among these, tangles of lianes and sprawlers such as Galium aparine and Solanum dulcamara occur. The field layer is typically dominated by a luxuriant cover of shade-tolerant, nutrient-demanding tall herbs, notably Urtica dioica, in mountain areas also Petastites hybridus, with a carpet of smaller plants beneath. Characteristically, much of the taller herb cover dies back quickly in autumn to leave a patchy carpet of mat-forming bryophytes on exposed mud. After a flood, there can be much woody debris washed in from upstream. This type does not include scrubs dominated by narrow-leaved willows S. eleagnos, S. purpurea and S. viminalis which fall within F9.1 Temperate and boreal riparian scrub.

Indicators of quality:

● Undisturbed hydrology with natural disturbance, at least periodically inundated with flood waters in uncontrolled stretches of mature rivers, though remnant stands can persist for some time around naturally isolated ox-bows.

  • Survival of larger stands of forest continuously developed along the rivers without fragmentation and isolation
  • Few if any signs of exploitation for timber, fallen trees remaining in situ and ample deposition of natural organic debris from flooding.
  • No signs of eutrophication or pollution by anthropogenically enriched flood-waters, for example excessive spread of nutrient-demanding weeds.
  • Absence of non-native tree species (Alien Poplar, Robinia pseudoacacia, Acer negundo...) and absence of invasive aliens such as Reynoutria japonica or Impatiens glandulifera.
  • High diversity of epiphytic bryophytes (eg. Orthotrichum spp.)

Threat status

Synthesis of Red List assessment

Even if the decline in quantity has been slight (-13.4 to -13.8%) for the last 50 years (the current trend is still a decline in most countries), the Near threatened category is reached because of a more than moderate decline in quality (54 to 55 %) on 34 to 35 % of the surface (between 30% and the 50% level that qualifies the Vulnerable category). The situation is very different between countries, and a VU, EN and even CR category would have been reached in some countries (especially in central Europe). In North-western Europe the situation seems to be better. The current trend is still a decline in quality in many countries, except in north-western countries (British Isles, Benelux, Germany).

Conservation and management needs

The keys to the conservation of temperate and boreal softwood riparian woodland are a strict protection of remaining sites, especially from expansion of land uses for urbanisation and agriculture, but also from Populus plantation, from damming and river regulation, and conservation or improvement of water quality. A free flowing river should experience floods allowing aggradation and nutrient- deposition, soil and vegetation rejenuvation (erosion and destruction of trees).

Distribution

For each habitat a distribution map was produced from a wide variety of sources indicating known and potential occurrences of the habitat in 10x10 km grids within Europe. Occurrences in grid cells were given in two classes: actual distribution from relatively reliable sources (surveys, expert knowledge), and potential distribution based on models or less reliable indicators. Please download the fact sheet to see the map.
