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 Bluethroat, Savi's Warbler and Western Marsh Harrier. Great Reed Warbler has become more regular. Bearded Tit appears on passage and in some years has stayed to breed. Penduline Tit has bred but nowadays is generally a scarce migrant. There is a Grey Heron colony and scarcer relatives such as Black-crowned Night Heron, Little Egret, Little Bittern, Purple Heron and Great Bittern 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 Green Sandpiper, Wood Sandpiper, Common Sandpiper and Common Greenshank. Common Redshank, Dunlin, Little Ringed Plover, Common Ringed Plover, Ruff and Spotted Redshank are no longer regular but also possible. Local scarcities such as Black-tailed Godwit, Avocet, Whimbrel, Curlew Sandpiper, Temminck's Stint and even Red Phalarope have all been recorded here and along the river. European Golden Plover and Dotterel have been recorded migrating overhead on occasion.
Common Crane, Black Stork and White Stork are regular visitors, and the latter has started to breed. The woodlands hold good numbers of Common Nightingale and Golden Oriole. Middle Spotted Woodpecker has recently colonised the area. In adjacent meadows and scrub Red-backed Shrike, European Stonechat, Western Yellow Wagtail and Corn Bunting can be found on passage and breeding. Little Owl and Long-eared Owl breed, as does Eurasian Hobby, Red Kite and Black Kite.
Wildfowl numbers, mostly dabbing ducks, build up modestly in Spring and Autumn with Common Teal, Mallard, and Gadwall 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 Greylag Goose, the most regular being Greater White-fronted Goose, followed by Tundra Bean Goose. A Whooper Swan was a recent and unusual overwinterer. Water Pipit 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.
