Wälder im Süderhackstedtfeld Nature Reserve: Mapped Geographic Boundaries and Forest Landscapes

The reserve is especially known for its atlantic, acid beech forest with holly and occasional yew, a priority habitat type under the EU Habitats Directive that here has been assessed as in excellent overall condition, a relatively rare result in the Schleswig part of Schleswig-Holstein. Equally important is the continuity of woodland cover documented continuously at least since 1852, the mix of additional forest habitat types such as stellaria oak-hornbeam forest and old acid pedunculate oak forest, and the ongoing, long-term process of converting remnant spruce stands into native broadleaf forest over a 50 to 100-year horizon.

The current protection regime began in the early 2000s as part of the EU Natura 2000 network. The standard Natura 2000 data form for Wälder im Süderhackstedtfeld was prepared by the forestry department of the Landwirtschaftskammer Schleswig-Holstein in May 2004. The site was proposed as a Site of Community Importance in September 2004, confirmed at EU level in November 2007, and nationally designated as a special area of conservation in January 2010 under Section 32 (2 to 4) of the Federal Nature Conservation Act together with Section 23 of the Schleswig-Holstein State Nature Conservation Act.

The accompanying management plan was published in October 2006 by the forestry department of the Landwirtschaftskammer Schleswig-Holstein. Schleswig-Holstein's general six-year monitoring cycle would have called for the next formal conservation status review in 2012, but as of late 2020 no follow-up monitoring results had been published.

Ecologically, however, the story is much older. On the Danish General Staff map of 1852, both of today's forest patches are already mapped as woodland, confirming long continuity of forest cover. A significant ownership shift occurred in 2006 when the larger eastern parcel, the Süderhackstedter Holt, came under the Stiftung Naturschutz Schleswig-Holstein, and some private owners expressed willingness to sell additional plots to the foundation, increasing the prospects for cohesive long-term habitat management.

The reserve sits in the Bredstedt-Husummer Geest, a gently undulating geest landscape shaped by glacial and periglacial processes. Its topographic backbone is a low, elongated geest ridge that runs east-west between Sollerup and Sollwitt, flanked to the south by the forest area and rising locally to about 34 to 36 m above sea level.

Within the protected boundary, elevation ranges from about 13 m at the southern edge of the western parcel to about 34 m at the northern forest edge, giving a relief of roughly 20 m. This modest elevation range is enough to produce noticeable slope effects, with the southern exposures of the ridge shaping local humidity and soil conditions.

The overall horizontal extent of the site is about 2.45 km in its longest east-west dimension. Surrounding land use is largely agricultural, with meadows, fields, and small roads framing the forest, including the regional L90 road along the ridge. The forest does not form a visually dramatic landscape in the Alpine sense, but it represents a characteristic, gently rolling Schleswig-Holstein geest scenery, where low ridges, open farmland, and relict woodlands alternate.

The site's ecological character is that of a mosaic of lowland, mostly broadleaf forest habitats on geest soils. The defining feature is the priority habitat of atlantic, acid beech forest with holly understory and occasional yew, an Atlantic-influenced forest type that here is in unusually good condition for the Schleswig region, where such habitats are generally scarce in excellent state.

Alongside this, the reserve contains Hainsimsen beech forest, Waldmeister beech forest, stellaria-type oak-hornbeam forest, and old, acid pedunculate oak forest on sandy ground, producing a layered mosaic of canopy types and understory structures. Smaller patches of alder-ash and softwood floodplain forest indicate water-influenced soils at the margins of the site.

Forest structure is shaped by limited but specific disturbances. Some small conifer stands, mainly Norway spruce and Sitka spruce, persist as patches within the broader deciduous matrix and represent a long-term restoration target. Deadwood and age-class diversity are identified as areas where the forest is still developing toward more natural structural patterns. A small central clearing with extensive grassland adds an open element within the otherwise continuous forest, increasing habitat heterogeneity locally.

The reserve's wildlife profile is shaped less by conspicuous large mammals than by the ecological conditions of its forest habitats: deadwood, mast years, and understory structure for invertebrates, fungi, and cavity-using species are central to its ecological value.

Grazing pressure from roe deer (Rehwild) and especially fallow deer (Damwild) is locally high enough to suppress natural tree regeneration outside fenced areas, which has motivated enclosure as a management tool. This indicates that the site supports populations of both species at densities that meaningfully interact with forest regeneration dynamics.

More broadly, the atlantic beech and oak-hornbeam forests of this kind typically support diverse communities of woodland birds, saproxylic insects, and forest-floor flora. However, the source material does not list specific fauna species in detail, and any further species commentary would go beyond what is supported.

Wälder im Süderhackstedtfeld is protected primarily as a Natura 2000 site under the EU Habitats Directive, with about 76 hectares designated to conserve specific Annex I forest habitat types. Its conservation importance is disproportionate to its size because of the unusually high assessment of its atlantic, acid beech forest habitat and its potential contribution to a coherent network of lowland woodland sites in Schleswig-Holstein.

Approximately one-third of the area is additionally protected as legally designated biotopes under German nature conservation law, providing a second, domestic layer of protection on top of the EU designation. The site also benefits from being embedded in a landscape of otherwise long-established forest cover, a factor that strengthens habitat connectivity at the landscape scale.

Long-term conservation strategy focuses on gradual forest restoration rather than dramatic intervention. A planned 50 to 100-year conversion aims to replace non-typical conifer stands with native broadleaf woodland. Recommended hydrological measures include rewetting drained forest areas at the southern edge of the Süderhackstedter Holt and ceasing maintenance of drainage infrastructure, indicating recognition that restoring natural water regimes is part of the site's long-term ecological future.

Culturally, the reserve is tied to a long history of low-intensity rural land use in the geest region of northern Schleswig-Holstein. Small-scale use of the forests for firewood continues within the site, and a traditionally managed, extensively used grassland clearing sits in the middle of the larger eastern parcel, demonstrating the coexistence of woodland and open-ground uses within a single property.

The Süderhackstedter Holt, the eastern main forest, has been under continuous woodland use and ownership shifts that include its current stewardship by the Stiftung Naturschutz Schleswig-Holstein, reflecting a broader regional pattern of conservation foundations taking on the long-term care of ecologically valuable forest estates. The site's appearance on the 1852 Danish General Staff map as already-formed woodland gives it a tangible historical depth that links today's EU-level nature protection with older patterns of forest continuity in this corner of Schleswig-Holstein.

A standout feature is the priority atlantic, acid beech forest habitat with holly understory, assessed as in excellent condition (Gesamtbeurteilung A) and considered rare in such high quality within the Schleswig portion of the state.

Additional highlights include the documented continuity of woodland cover since at least 1852, the compact mosaic of multiple Annex I forest habitat types within a single 76-hectare site, and the active long-term forest conversion program that aims to replace non-native conifers with ecologically appropriate native broadleaf woodland over the coming decades.

The site is not a developed visitor destination; access is generally limited, paths are few, and summer vegetation (Verkrautung) can make movement through the forest more difficult. As such, it functions mainly as a quiet, low-traffic woodland for walkers who prefer uncrowded, naturally managed forests.

For those who do visit, late spring to early autumn is the typical window when understory plants and broadleaf canopies are most expressive, but heavy summer growth reduces accessibility and the absence of formal visitor infrastructure means visitors should expect minimal signage and orientation. Cooler months bring quieter forest atmospheres and easier walking conditions, though the muted vegetation display. Source material does not support more specific seasonal or accessibility claims.
