ABSTRACT
This paper focuses on the restoration of extinct ponds. The number of extinct ponds in the Czech Republic is very high as many ponds ceased to exist since the Golden Age of fish farming which is dated to 15th century. The restoration of such ponds is considered as one of possible ways to increasing landscape retention capacity which is supposed to be a part of measures for mitigation of considered climate change impacts. These are expected to result in more frequent floods having higher magnitudes and on the other hand in longer and more frequent periods of droughts. The restoration of extinct ponds can be advantageous mainly with respect to the possible use of dam residues for building new reservoir which can save a lot of financial resources. Another reason for consideration of extinct pond areas for given purpose is the suitability of their profiles as these were mostly carefully selected in past. However, there are also aspects which make the restoration impossible or inappropriate. These are besides others the urbanization and nature protection or environmental issues. This paper focuses on the assessment of above mentioned aspects which can be a reason for which the restoration is not possible. The results show, that from the point of view of frequency the urbanization is more important aspect than the environmental issues. However, there are still many extinct pond areas which could be restored into water bodies even after exclusion of those which cannot be restored due to urbanization or environmental issues.
