Summary

The tall forb communities of Habitat type E5.5 are found at relatively cool and humid places in low and high mountain ranges throughout Europe, with their optimum in the subalpine zone; moreover, they can be found in the arctic regions of Scandinavia. They can be seen as a vicariant of the communities of habitat type E5.4, occurring at lower altitudes. In the mountains of Central Europe, the communities usually occur above 1,000 m altitude, but in Southern Europe they often don’t grow below 1,600 m. The stands occur along streams, between large rocks, under scrub (mainly of Sorbus aucuparia), in mosaic with Alnus and Salix scrub, and on the edge of forests. In spite of the high atmospheric humidity, bryophytes do not play an important role in the vegetation. At all these places, snow may accumulate during winter and the vegetation is unmistakeably chionophilous. Along streams, the communities may form long strips of hundreds of meters, mostly just a few meters wide, at other places they occur in the form of patches. The height of the – generally one-layered – stand reaches up to 1.5-2 m, with tall herbs and grasses as dominants, sometimes with a high cover of ferns. The cover of the vegetation is almost always 100%. The species composition of the plant communities is very diverse, with a high number of endemic species, reflecting the isolated position of these ecosystems, similar to other high-mountain vegetation types. The endemic species belong to genera like Aconitum, Alchemilla, Angelica, Cirsium, Geum and Ranunculus. From a historic-geographic point of view, the occurrence of a number of species that nowadays dominate lowland meadows is interesting, like Arrhenatherum elatius. Widespread species in these conspicuous mountain communities are Adenostyles alliariae, Veratrum album, Lilium martagon and Cicerbita alpina, among others. The plant diversity is reflected in the distinction of various alliances, but they all belong to the class Mulgedio-Aconitetea. Most of the communities are natural, but also the semi-ruderal and eutrophic tall-forb communities near resting places of cattle (assigned to the alliance Rumicion alpini) belong to this habitat type.

Indicators of good quality:

High species richness
Richness of regional endemics and rare species
Lacking of invasive and/or ruderal species
Dominance of tall-herbs, tall grasses or ferns

Human intrusions and disturbances

Mountaineering & rock climbing

Habitat restoration potential

These natural communities are well protected. Only at a local level and at low scale, direct destrucion of the habitat by the construction of tourist facilities may take place, whereas - more generally - overgrazing may lead to some losses in quality. In that case, lowering the intensity of grazing may lead the habitat restoration within a reasonable time-span.

Conservation and management needs

The natural conditions under which these eye-catching and species-rich communities occur are hardly effected by human interaction. Locally, the effects of mountaineering and construction of buildings and ski pistes for tourism may rise some concern, but overall the habitat type is well-preserved.

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.
