Life Trockenrasen: Suppression of Neophytes

Introduced plant species have spread across many dry grassland areas.

Neophytes such as black cherry (Prunus serotina), black locust (Robinia pseudoacacia), ash-leaf maple (Acer negundo), American red oak (Quercus rubra), meadow goldenrod (Solidago canadensis) and common lilac (Syringa vulgaris) can develop well on dry, sandy sites. Due to their rapid growth, smaller plants often no longer have a chance of getting enough light and space. In addition to the loss of dry open habitats, neophytes sometimes also change the site properties, for example by accumulating nitrogen in the soil.

Effective removal of woody neophytes is often difficult. Species such as the black cherry or the black locust sprout again after being cut down and form dense bushes. Experience has shown that removal is only possible through a combination of several measures over a period of two to five years. Methods such as girdling and felling again after two to three years have proved successful. In addition, it is usually necessary to clear the stumps and basal roots.
