An Entomologist Reports Rare Findings in the Maříž Wetland

The wetland near Maříž, one of the sites in Refugium’s portfolio, is teeming with life. The excellent biodiversity of the site is reflected in 2021 by an extensive biological survey, which confirmed the presence of several endangered plant species and 14 species of amphibians and reptiles.

Among these, we can name the northern crested newt (Triturus cristatus), the common spadefoot toad (Pelobates fuscus), the European tree frog (Hyla arborea), a strong population of the agile frog (Rana dalmatina), the viviparous lizard (Zootoca vivipara), or the smooth snake (Coronella austriaca). We are also giving a chance to the moor frog (Rana arvalis) as its presence has been confirmed just outside the perimeter of the property.

Far from resting on our laurels, we’re continuing our research in the wetland park. Currently, we’re monitoring small mammals and carnivores in cooperation with ALKA Wildlife and conducting extensive entomological research focused on water beetles, xylophages (insects that feed exclusively on wood), and dragonflies.

The author of the research on dragonflies, batrachologist, entomologist, and chairman of the Hamerský Potok group Petr Hesoun has already brought us the first batch of good news. He discovered several hairy dragonflies and one male scarce chaser (Libellula fulva).

These species are listed as NT, or near threatened, on the IUCN’s Red List, but in South Bohemia the hairy dragonfly is very rare and the sighting of the scarce chaser is only the second to be recorded. It will be part of a forthcoming book on dragonflies of South Bohemia.

We hope that you share our happiness and may these be far from the last positive results!
