Zástudánčí National Nature Reserve

The NNR represents a preserved alluvial forest along an unregulated Morava river channel under the confluence of the Morava and Bečva rivers, which is also a significant habitat for bird nesting and migrating. The geological basement is composed of the Holocene river sediments of ballast and sand with alluvial sandy loams. The unregulated water course allows the Morava River to overflow into the alluvial softwood forest in the spring. Gravel sand was directly extracted out of the waterway until the end of the first half of the 20th century when it was discontinued as a result of declaring this territory as a protected area. The mining activity is currently done in the close vicinity. There are a few probes located in the nature reserve to draw natural gas which is stored in the gas underground storage in the water-bearing basement. This technical unique feature has an adverse effect on forest stands. Zástudánčí NNR is included among wetlands of supraregional importance and as such it is also a part of the Chropyňský luh (alluvial forest) Supraregional Biocentre. A total of 174 bird species have been observed during the ornithological research, of which 78 nest in the nature reserve regularly and 7 irregularly and rarely. The colony of grey heron (Ardea cinerea) nests in the vicinity, therefore the protected territory is considered to be extended to include this area. The remnant populations of the black poplar (Populus nigra) are located here and the selected trees are used as a source of seed (European white elm (Ulmus laevis), small-leaved elm (Ulmus minor) and narrow-leaved ash (Fraxinus angustifolia).
