The Czech Society for Ornithology started buying up land in an area next to the river Metuje and restoring and imitating its original appearance and function of a floodplain.

[2] Thanks to public donations and sponsors, the Society has bought and repaired a hundred-year-old irrigation system that maintains a higher level of groundwater and is used twice-yearly to imitate natural spring and autumn flooding of the meadows.

In 2016 there have been observed for example short-eared owl, common crane, northern shoveler[5] or garganey, attempting to nest thanks to the appearance of Eurasian beaver.

The 25 species of the odonata genus illustrates the improving quality of the protected ecosystem, with southern emerald damselfly and yellow-winged darter dependent on the wet meadow environment, rare in the Czech Republic.

[7] Since the wild horses are not being chemically dewormed, their manure is attractive to many insect species, providing additional source of food to local birds.
