Image of Inula salicina

Description:

Slo.: vrbovolistni oman - Habitat: roadside, ruderal fill of the dirt road leading to a small bridge, on alluvial, calcareous ground; river bank, full sun, high air humidity; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 590 m (1.950 feet), alpine phytogeographical region. Substratum: soil. Comment: Inula salicina is an Eurasian temperate botanical element, with a continental distribution in West Europe. It is not really a rare plant in Slovenia. But in several other countries it is in decline, which is presumably attributed to increased eutrophication of environment. In UK only a single spot (Lough Derg, Ireland) where one can see it remained. The pictures show a recent find of the species, which is, as far as we know, the first in the in Upper Soa river region and one of the few known in the alpine phytogeographical region of Slovenia. The stands are quite far from all other known occurrences but clearly of secondary (subspontaneous) origin, probably introduced during the construction of the bridge over the river Soa.
