Boberger Niederung nature reserve
Boberger Niederung nature reserve
|location||North-west of Lohbrügge|
The approximately 350 hectare area was placed under protection in 1991 and includes the natural monuments Boberger Düne and Achtermoor , which have existed since 1968 . The Boberger Niederung includes geest , moor and marshlands , as well as a quarry pond, the Boberger See with bathing areas. The inland dunes are a popular destination for local recreation. The farms that existed in earlier times, such as the “Uhlenburg”, were given up and resettled in Klein Nordende near Elmshorn .
The Boberger slopes with their orchid meadows have also been added. The Ladenbek stream runs through the area. Nature conservation experts speak of the Boberger Niederung as the botanically most valuable area of the Free Hanseatic City of Hamburg. Many animal species that are already on the red list are still at home here; 110 plant species that are also registered on the red list, such as thistle , centaury and swamp heart leaf , still occur here. Among the five orchid species to be found here , mosquito-handelwort , broad-leaved and swamp-stendel-arum , large two -leaved and broad-leaved orchid is one that is not found anywhere else in Hamburg.
Although some animal species, such as the woodlark , have no longer been found in the Boberg lowlands in recent years , many endangered animal species still have a place of refuge here: the blue moor frog , the blue-winged wasteland shrimp , the green woodpecker and the kingfisher . Endangered butterflies such as green rams and blood droplets and other insect species such as dune tiger beetles , wart- bites and ant lions also find shelter here.
The central part of the protected area area forms the FFH area Boberger Düne and slope terraces .
rivers and lakes
The Ladenbek was once a small spring creek that arose between today's roads Weberade and Grand coupling from a marsh area and from Geesthang by dry areas on Moosberg flowed to ultimately lead to the Bille to. The increasing development made it necessary to artificially guide the course of the Ladenbek.
The hair pond is the only body of water in the Boberger Niederung that lies entirely in fine dune sand and is therefore very poor in nutrients. When the pond was contaminated with nutrients, the habitat of the natterjack toad was initially destroyed. However, following the initiative of nature conservation organizations, the pond was cordoned off with a fence and has increasingly recovered. The natterjack toad was finally successfully reintroduced.
Conservation information house
In the street Boberger Furt there is the dune house (formerly nature conservation information house) of the Loki Schmidt Foundation ( ).
The house offers its visitors an exhibition on the geological and historical development of the Boberg lowlands and the biological characteristics of the nature reserve with its various habitats. In addition, guided tours through the nature reserve are offered and there is cooperation with associations and school classes from the area. There is a participation in the planning and implementation of maintenance measures in the nature reserve. There are also lectures and events on topics related to natural history, nature conservation and environmental protection.
In the nature reserve four nature information trails are signposted, which lead through the various vegetation zones of the Boberger Niederung.
Julia Stoess' insect models were on view in the information house exhibition until January 2010. The foundation offers two places in the Voluntary Ecological Year at this location .
Toxic contaminated sites
At the end of 2018, routine investigations by the Hamburg environmental authority revealed dioxin contamination of the soil. It is believed that toxic industrial waste was dumped from the train here in the 1960s. An embankment of around 1,500 square meters is contaminated as a result.
