Latumer Bruch Nature Reserve and Protected Wetland Landscapes in Nordrhein-Westfalen Germany

The Latumer Bruch takes its name from Haus Latum, a historic manor farm on the edge of Lank-Latum, whose lands historically encompassed the wetland. For centuries the area was part of the agricultural and estate landscape of the Lower Rhine, shaped by the meander channels and seasonal flooding of the Rhine.

Its formal conservation history began in 1982, when the site was designated as a nature reserve (Naturschutzgebiet) under the designation KR-001. This step recognised both its ecological value as a floodplain forest and its role as a natural floodwater retention area. Over time, the reserve became embedded in larger conservation frameworks. It is now part of the EU Natura 2000 / FFH site DE-4605-301, which links it to the adjacent Buersbach reserve, Linn Castle's moat and city ditch system, the Greiffenhorstpark and the Elt waterworks area. It is also incorporated in the Biotopverbund Krefelder Süden, a regional programme connecting protected habitats across southern Krefeld. Today the area is managed by Krefeld's lower landscape authority together with NABU and a volunteer landscape warden.

Ecologically, Latumer Bruch is defined by the contrast between its swamp-and-floodplain forest core and its surrounding dry grassland ridges. In the wettest areas, alder, willow and poplar form classic Bruchwald and Auwald communities, their roots anchored in waterlogged, peaty soils. Beneath and beside them grow a layered understorey of reeds, sedges and bur-reed, along with characteristic wetland flowers such as marsh iris (Sumpf-Schwertlilie) and marsh marigold (Sumpfdotterblume).

On the dry Donke ridges, conditions shift dramatically. Here, low-intensity grazing and nutrient-poor sandy soils have allowed a semi-natural dry grassland (Magerrasen) to persist. Autumn crocus (Herbstzeitlose) and cuckoo flower (Wiesenschaumkraut) are among the indicator species of these open meadows, which contrast sharply with the dense wetland forest only a short distance away.

This juxtaposition of habitats within a single small area supports a particularly wide range of invertebrates and plants for a protected site in such an urbanised setting. The mosaic also provides year-round feeding, breeding and shelter conditions for birds, amphibians and insects that depend on transitions between open water, wet woodland and open grassland.

Latumer Bruch is recognised above all for its birdlife. The wet meadows, ditches and ponds provide rich feeding for waterbirds and meadow birds, and the reserve is known as a breeding area for species such as the white storch and the black kite. Many migratory birds also use the area as a resting and refuelling station on their seasonal journeys, drawn by its reliable supply of water and food.

The amphibian fauna benefits from the network of pools and wet ditches. The great crested newt (Kammmolch) is among the notable species recorded here, alongside other amphibians that use the still water as breeding habitat. The mix of dry grassland, wetland edge and open water also supports diverse insects, including specialised butterflies such as the Schwarzblauer Bläuling and the Großer Moorbläuling, as well as the Veränderlicher Edelscharrkäfer, a rare beetle.

The reserve's larger mammals include roe deer and European hare, both of which are reported in the low-intensity meadows and woodland edges. The overall wildlife value of Latumer Bruch comes less from individual rare sightings than from the persistence of a diverse, functionally connected community of wetland, meadow and woodland species within a single small landscape.

The primary conservation significance of Latumer Bruch is its role in preserving an intact functional example of Lower Rhine floodplain ecology. Swamp forest, floodplain woodland, wet ditches, ponds and semi-natural grassland coexist here at a scale large enough to sustain breeding populations of wetland birds, amphibians and specialist invertebrates within an otherwise heavily urbanised region.

The reserve is a recognised component of the European Natura 2000 network, integrated into the FFH site DE-4605-301 'Latumer Bruch mit Buersbach, Stadtgräben und Wasserwerk'. This larger designation links Latumer Bruch to the Buersbach reserve, the Linn Castle moat system, the Greiffenhorstpark and the Elt waterworks area, creating a continuous conservation corridor of nearly 300 hectares. Locally, the site is also part of the Biotopverbund Krefelder Süden programme, which connects protected habitats across southern Krefeld.

In addition to its biodiversity value, the reserve contributes to flood management. The old Kendel channels act as natural retention basins when the Rhine is in flood, absorbing pressurised groundwater that would otherwise accelerate downstream flooding. Long-term, low-intensity grazing and active management by the city's lower landscape authority, NABU and a volunteer warden help maintain the open grassland mosaic that supports meadow birds and butterflies.

The cultural context of Latumer Bruch is closely tied to the historic manor landscape of the Lower Rhine. The reserve is named after Haus Latum, a traditional estate farm on the edge of Lank-Latum, and the wetland was once part of that estate's land. The name 'Lohbruch' preserves an older local term for the area.

The reserve also sits within a broader heritage landscape south of Krefeld: it neighbours Linn, the city's oldest quarter with Linn Castle and its historic moat system, and lies within the corridor between Lank-Latum, Ossum-Bösinghoven, Oppum and Gellep-Stratum. These communities retain traces of the agricultural and water-management traditions that shaped the use of the Rhine floodplain for centuries.

Latumer Bruch combines several standout qualities in a small area: intact Bruchwald and Auwald swamp forest, a network of ponds and wet ditches, species-rich dry grassland ridges, and old Rhine meander channels that still function as floodwater retention basins. It is well known for breeding waterbirds and meadow birds, for hosting migratory species, and for amphibians such as the great crested newt.

Its role as the core of a larger Natura 2000 site linked to Linn, the Buersbach and the Elt waterworks gives the reserve an importance well beyond its 185 hectares. Together with surrounding nature reserves and parks, it forms a continuous green corridor along the southern edge of Krefeld.

As a lowland wetland on the Lower Rhine, Latumer Bruch has the most atmospheric character in spring and early summer, when water levels in the old channels are naturally high, vegetation in the swamp forest is at its lushest, and marsh flowers such as marsh iris are in bloom. This is also when breeding waterbirds and meadow birds are most active and amphibians are most visible around the pools and ditches. Late summer and early autumn bring the distinctive flowering of the autumn crocus on the dry Donke grassland ridges, while late autumn and winter can deliver the highest water levels, when groundwater pushed up by Rhine floods fills the channels and turns the area into a broad shallow wetland.
