Abstract

Bachelor thesis points out the importance of abandoned orchards and tree alleys in the mining landscape of Karvina region, in which daily butterflies were observed. The aim was to determine whether exists a relation between butterflies and abandoned or maintained orchards and tree alleys. The work deals with the study of daily butterflies as a group of animals sensitive to changes of their natural environment and their lives in environment changed by mining activities. This thesis describes the order of daily butterflies (Lepidoptera: Rhopalocera), it concerns the morphology, relation to fruit trees in orchards and tree alleys in mining region in which was carried out the research and evaluation of data including comparison of the numbers in abandoned and maintained orchards and tree alleys. There were selected eight locations in the (post)mining landscape of Karvina region. These were fruit orchards and tree alleys. These locations have nature of extensive and intensive orchards and tree alleys, which are important for the existence of daily butterflies. Within the observations were caught some representatives of daily butterflies for further determination. During the research in concerned areas was recorded number of occurrence of discovered species and also compared diversity of daily butterflies in abandoned or maintained orchards and tree alleys. It was found that in concerned areas which were abandoned was recorded an increased number and greater variety of daily butterflies compared to maintained orchards and tree alleys in concerned (post) mining landscapes of Karvina region.
