Fine-leaved Vetch / Langklaset Vikke

Fine-leaved Vetch / Langklaset Vikke

Vicia tenuifolia 

In Denmark: 
Fine-leaved Vetch / Langklaset Vikke is native and first of all registered in the Danish Isles  At Funen at Hindsholm, at Zealand along the coast of Storebælt, the inside of Isefjord and Roskildefjord and at the island Møn. (Jessen 1931)

Fine-leaved Vetch has still a main occurrence area in the northeast of Funen, Northwest Zealand, Stevns and East Møn. Also some sporadic discoveries in Jutland and at the island Falster. 
(Christiansen og Prehn 2009, Faurholdt 2006, Næsborg et al. 2001, Tranberg et al. 2002, 2003, 2005, 2007, 2009) and at Bornholm, where it was observed in 1985. (P. Wind pers.obs. 1985).

There are no informations about the population-development  of Fine-leaved Vetch/ Langklaset Vikke. The species is possibly vaguely declining .  It seems that it tolerates mowing in light-open facilities. (Næsborg et al 2001). It is able to spread secondary to culture-affected soil in edge of ditches, at railway slopes, in cultures with greenery and edges of roads. (Faurholdt 2006, Hansen, A. 1977, 1981, 1982, Lyshede 2004):

Fine-leaved Vetch /Langklaset Vikke is native to most of Europe and the northwestern part of Africa. The spread of the species reaches the Caucasus to the east and the central part of Asia. The northern limit of its distribution is the middle part of Sweden  (Hultén og Fries 1986) (.Christiansen og Prehn 2009, Faurholdt 2006, Hansen, A. 1977, 1979, 1981, 1982, Hansen, K. 1981, Hultén og Fries 1986, Jessen 1931, Lyshede 2004, Næsborg et al. 2001, Tranberg et al. 2002, 2003, 2005, 2007, 2009, Tutin et al. 1964-1980).
