Title Halophytes at potash-mine dumps in Germany and France (Alsace)
Source Tuexenia
Abstract Potash-mine dumps in Central Europe have been colonized by numerous halo-tolerant vascular plant species during the last decades. Current data on the occurrence of 35 selected halophytes at 84 potash-mine dumps in Germany (Lower Saxony, Saxony-Anhalt, Thuringia, Hesse, Baden-Wurtemberg) and 12 in France (Alsace) were collected and evaluated. Among them Spergularia media (68 dumps), Spergularia salina (62 dumps) and Hymenolobus procumbens (58 dumps) occur most frequently on potash-mine dumps. Hymenolobus procumbens is a good example for the recent spectacular expansion of halophytes. Most of them can be found on potash-mine dumps in Lower Saxony. Compared to other regions, Apium graveolens, Atriplex pedunculata and Triglochin maritimum are listed most frequently here. Atriplex tatarica and Scorzonera laciniata were found more frequently on potash-mine dumps in Saxony-Anhalt and Atriplex rosea and Bassia scoparia in Thuringia. Furthermore there is a strikingly late colonization of potash-mine dumps by remarkable halophytes in Hesse and a high constancy of Hordeum jubatum. Salicornia europaea ssp. brachystachya and Suaeda maritima could be found in Baden-Wurtemberg for the first time. Only a few halophytes colonize the potash-mine dumps in the Alsace north of Mulhouse, among them Chenopodium botryodes and Dittrichia graveolens. These two species cannot be found on potash-mine dumps in Germany. Atriplex longipes was identified at the bottom of a potash-mine dump near Wittelsheim and is quite new in France. The occurence of endangered halophytes on 90 % of the German potash-mine dumps shows their immense importance for the species protection of vascular plants. 18 potash-mine dumps have been colonized by more than 4 species listed in the German Red Data Book, among them such highly endangered species as Bupleurum tenuissimum and Plantago maritima.
