Tekst równoległy w języku polskim. Tłumaczenie z jęz. niemieckiego mgr Arkadiusz Niewiadomski ; Na podstawie badań przeprowadzonych w środkowej Hesji Autor dokonał podziału typologicznego linearnych struktur trawiasto-zielnych, przedstawił charakterystykę ekologiczną miedzy typowej i miedzy podlegającej sukcesji oraz wykazał związki między liczebnością gatunków roślin a intensywnością zagospodarowania powierzchni sąsiadujących z różnymi formami miedz. Praktycznym aspektem przeprowadzonych badań jest określenie minimalnej szerokości miedzy, przy której występuje jeszcze znacząca liczba gatunków roślin. ; Grass and herbal dominated small line structures possess high significance for the conservation of species and biotopes in the actual cultural landscape of Germany. This paper categorizes and specifies herbal ridges, central stripes of lanes and pasture fences. These biotope-types are then differentiated to herbaceous seams. The floristic and vegetational composition of herbal line structure elements is analysed at four different levels, which are: species inventory, floristic types, phytocoenoses and nano vegetation complexes. Each level is characterized by its species and biotope conservation value. While floristic types are useful for ecohabitat aspects and species conservation, nano vegetation complexes are advised for work on large areas. The ecological significance of a herb-dominated small line biotope depends decisively on the production intensity of the land use above it (uplier), its cultivation state and its breadth. Line structures serve as refugial habitats. Starting from here the recolonization of adjacent grasslands and arable ground takes place. In order to perform this function in the future, preservation of these line structures is needed. An extensivation in agriculture over large areas will secure these efforts. Biotope-binding measures without large area extensivation of agriculture will only delay the destruction of the line biotopes left. Care should be spent on the methods used to maintain line structures, especially whether they are realistic. The effective shelter of herb-dominated small line structures is difficult because information on their composition lacks. Agriculture plays an important role in the management of these structures. Central demandments to an effective conservation of herb-dominated small line structures are: Reduction of nutrient flow into these structures (reduction of production intensity on 6kologische Bedeutung und Naturschutzpotential . 111 adjacent fields, buffer strips), guarantee of line structure management and keeping a minimum breadth of line structures (depending on the nature area between 2.5 and 3 m). The joining of Poland to the European Union causes several problems to agriculture and biodiversity. There will be exist less linear structures after this change. There are two steps to conserve linear biotopes; fIrst to investigate the status quo of biodiversity and second to initiate conservation of linear structures.

The article looks at the defense and promotion of human rights – and of the osce's broader human dimension of security – in a context of what could be called "multiple crises", i.e., the crisis in and around Ukraine, the refugee crisis in Europe, and the threat of terrorism. While the inclination might be to address these crises with a classical "politico-military" approach, the argument here is that an approach based on ensuring the human dimension of security – human rights, the strengthening of democratic institutions and the rule of law, and promoting tolerance while combating discrimination – is just as vital if real and lasting resolutions to these crises are to be found. The article argues that, while the current crises represent dangers in relation to security in the osce area, they also represent opportunities to reaffirm the importance of the human dimension as part of the osce's comprehensive approach to that very same security.
