The Kattbek Dunes

Evers ReForest and the Eversfrank Group actively support the Naturschutzverein Altenkattbek e.V. conservation efforts. Efforts include the systematic removal of purple moor grass. Under the direction of biological experts, various manual and technical methods are tested to create the necessary basis for the rapid spread of the original heath vegetation.

Around eight hectares of the 152 ha flora-fauna habitat area (FFH-area) “the Kattbek Dunes” have been made available to the conservation group “Naturschutzverein Altenkattbek e.V.” for active preservation. The soil composition of the FFH-area is distinguished by large sandar areas of Weichselian glaciation. In the post-Ice Age, a dune moorland landscape with forests on acidic soils and smaller bogs developed in flat depressions.

The aim is first to preserve the various habitats in this area also in order to be able to support a rich animal and plant life (biodiversity). The heath and moor matgrass are being crowded out by the predominant purple moor grass. This grass develops hummocks and thereby raises the nutrient content with large amounts of decaying plant material. At the same time, the entire area is threatened by invasive shrubs encroaching on the habitat. Due to shrubs and trees in the dunes, the low-growing plants receive too much shade, and this is responsible for introducing even higher plants. In order to be able to preserve the heath and moor matgrass, purple moor grass and young trees must be actively cleared.

Another threat to the natural vegetation is the North American black cherry (Prunus serotina). It was introduced to Europe in the 1950's, is fast-growing and spreads rapidly. In order to control this species effectively, young growth must regulary be cleared over a period of several years and all potential mother trees removed.
