Small interest in agriculture practiced under unfavourable natural conditions is one of the phenomena related to political changes in Central Europe at the end of 20(th) century (in the last decade). As a result, extensive areas of secondary grasslands have been abandoned and are now lying fallow. The existence and quality of secondary grassland depend, however, fully on human management, especially on further low impact agricultural practices.This paper presents some of the problems related to the management and development of secondary mountain grassland situated in a protected area. A reconstruction has been made of the post World War II changes in land cover/land use with respect to the history of its management to understand better its recent state. The evaluation of the last fifty years development is based on a quantification of changes identified by visual interpretation of a time series of aerial photographs, and by field surveys.Special interest is paid to the potential impact on local biotopes and ecosystem of planned resettlement of the territory and to multifunctional land use. Main objections to the lay-out master plan by the administration of nature conservation are discussed here. In this case, no simple solution about the secondary grassland enclaves development exists from an impartial point of view. Site specifics, historical context and societal preferences with a long-term perspective should be taken into consideration in the decision-making process.
