Description
The small river Selz has been renaturalised at this reserve and European Beavers have recolonised as well. Along with an area of flooded marshes, reedbeds, ponds, grassland and scattered riverine woodland, some regionally scarce breeders are present and over the years a wide variety of passage and winter birds have been recorded. Over 200 species are now on the reserve list. A concerted effort in Spring on a good day can produce 70 species at the reserve and along the river.
The main attraction for most will be spring and summer reedbed visitors, such as Modrovoljka, Veliki Cvrčić and Eja Močvarica. Veliki Trstenjak has become more regular. Brkata Sjenica appears on passage and in some years has stayed to breed. Sjenica Mošnjarka has bred but nowadays is generally a scarce migrant. There is a Siva Čaplja colony and scarcer relatives such as Gak, Mala Bijela Čaplja, Čapljica Voljak, Čaplja Danguba and Bukavac have all been recorded in recent years, some regularly.
Passage waders can be found on the pools or flooded grasslands, but this is heavily dependent on weather and water level conditions. More regular are Crnokrila Prutka, Prutka Migavica, Mala Prutka and Krivokljuna Prutka. Crvenonoga Prutka, Žalar Cirikavac, Kulik Sljepčić, Kulik Blatarić, Pršljivac and Crna Prutka are no longer regular but also possible. Local scarcities such as Crnorepa Muljača, Modronoga Sabljarka, Prugasti Pozviždač, Krivokljuni Žalar, Sijedi Žalar and even Riđa liskonoga have all been recorded here and along the river. Troprsti Zlatar and Šareni kulik have been recorded migrating overhead on occasion.
Ždral, Crna Roda and Bijela roda are regular visitors, and the latter has started to breed. The woodlands hold good numbers of Slavuj and Vuga. Crvenoglavi djetlić has recently colonised the area. In adjacent meadows and scrub Rusi Svračak, Crnoglavi Batić, Žuta Pastirica and Velika Strnadica can be found on passage and breeding. Sivi Ćuk and Mala Ušara breed, as does Sokol Lastavičar, Crvena lunja and Crna lunja.
Wildfowl numbers, mostly dabbing ducks, build up modestly in Spring and Autumn with Kržulja, Divlja Patka, and Patka Kreketaljka being the most easily encountered. Visibility can be a challenge with reeds obscuring the pools, so try using a scope from higher ground. In most winters, singles or low numbers of wild geese are recorded among the resident groups of Siva Guska, the most regular being Lisasta Guska, followed by Tundra guska. A Žutokljuni Labud was a recent and unusual overwinterer. Planinska trepteljka is regular on passage and sometimes winter.

Access
Limited free parking is available at a couple of small paved areas next to the L432 between Hahnheim and Sörgenloch. This road is also on a bus-route (652) with the nearest bus-stop at Wahlheimer Hof to the east of the reserve, or alternatively at Sörgenloch to the west. A path, paved only on most of the southern side, circumvents the pools, grassland, and reedbeds. Cycling this part of the southern edge is possible, but other stretches are often high grass (beware of ticks) and can be muddy depending on conditions. An official paved cycling route veers west of the reserve when at the south-western corner but returns to the Selz shortly afterwards. Beaver activity and excessive rain sometimes causes extensive localised flooding.
