The impact of uncut strips on the hay meadows to spider communities
Rothová, Helena ; Šípek, Petr (advisor) ; Hula, Vladimír (referee)
Until recently, the importance of grasslands in supporting biodiversity in Central Europe has been overlooked. It is only recently that the view that attention needs to be paid to this topic has become more prevalent. Grassland habitats are the most biodiverse places and many organisms have adapted to their traditional management. The post-war intensification of agriculture, associated with the intensive use of fertilizers, pesticides, large-scale mowing and the general homogenisation of production communities, has had a negative impact on overall biodiversity. The main causes of arthropod mortality include use of chemicals, mechanical destruction, resource and habitat loss. The European Union has therefore introduced a set of so-called agri-environmental-climatic measures (AEKO) to promote biodiversity in agroecosystems. Unfortunately, the partly erroneous and overly technocratic conditions of these measures have often caused them to be ineffective or even counterproductive. There is also a lack of knowledge about the impact of the measures on local communities. At the instigation of the Agency for Nature Conservation of the Czech Republic (AOPK ČR) and the company Envipor s.r.o., we tested the effect of unmown strips on different arthropod groups on 22 production meadows in the vicinity of the...
