Almost a third of all wild plants in Germany is in danger of extinction. The value of 30.8 percent have changed compared to the previous year, informed the Federal office for nature conservation (BfN) in Berlin. In the presented Red list, the stock situation is for 8.650 in Germany, native ferns and flowering plants, mosses and algae are presented.
reason for the poor state of the wild plants, especially the high nutrient, therefore, is a burden in soil, in bogs and heaths. The sun to over-fertilization in agriculture, as well as to pollutants in the air, for example car exhaust gases. So Arnica is love, for example, meadow pasqueflower, wild herbs of Arable fields and the now-endangered flame-Adonis nutrient-poor sites.
BfN President Beate Jessel said: “it is Striking how many endangered species are to be found among the typical species of nutrient-poor waters and other nutrient-poor sites such as bogs or heaths.” Thus, more than half of all zieralgen species is endangered.
are Altogether extinct in the past 150 years, 119 plant species in Germany, or have disappeared, including 76 fern and flowering plant species. No natural Occurrences are known in Germany.
Yet not all the species it is worse: At 18 fern and flowering plant species registered in the BfN growth. For example, the air quality improved for many plants Because power plants emit less sulfur, it is demonstrably mosses better, which grow on trees. Some diatom species do not more it helps that the lakes have acidic water. In the case of ferns and flowering plants in a Shrinkage of the stocks settled in the areas to stop, the Protection of arable land or field margins. This applies, for example, for the corn cockle or the thickness of Brome grass, earlier typical accompanying plants in cereal fields.
Such targeted assistance programs are not sufficient to protect the Species from declining. A nature should be to promote sustainable agriculture and the aquatic environment to be improved, said Jessel.
For the protection of biodiversity in Germany, the Red lists are an essential basis for this. They document the status of species and, indirectly, the impact of human activities on nature. Thus, they are early warning systems for the development of biological diversity and to show where action is needed.
For your new Red list, the researchers risk took account of ratings from six plant groups: ferns and flowering plants (4.305 species), mosses (1.195 species), in fresh water, abundant brown and red algae (34 species), hose algae (45 species), Zieralgen (968) and limnic diatoms (2.103). The list includes algae to the plants.
