Monitoring of the flower strip program in Saxony-Anhalt

  • Background

    Background

    The petite eyeglass pod (Biscutella laevigata subsp. Gracilis) occurs in Germany only in Saxony-Anhalt in the Saale valley north of Halle / Saale and with a few populations in the Elbe valley near Dessau. In total, only 23 sites are known for the period after 1980, some of which have only small populations. The state of Saxony-Anhalt therefore bears a special responsibility for the preservation of the species and its habitats.

    The perennial species is adapted to xerothermic and nutrient-poor habitats. In the course of land use changes (especially the decline in traditional sheep and goat grazing), the habitats of the petite eyeglass are increasingly endangered by abandonment of use and nutrient inputs. Creeping habitat deterioration and the associated low chances of germination and establishment increase the risk of genetic impoverishment in populations and local extinction. Thus, the maintenance or restoration of a favorable surface condition of the habitats is crucial for the continued existence and the promotion of the individual populations of this species. Biscutella laevigata subsp. gracilis is representative of numerous other plant species endangered by land use changes in xerothermic locations.

    Objectives

    The overarching goal of the project is the sustainable improvement of the existing situation of the type of responsibility and their living space in Saxony-Anhalt. Based on a scientific analysis of the current stock and threat situation, an implementation-oriented and area-specific protection and support concept for Biscutella laevigata subsp. gracilis developed and the first measures implemented. Both species support measures (e.g. population support) and maintenance measures for the preservation and development of the locations are to be carried out.

    Project flow

    The project implementation is divided into the following steps:

    1. Research and consolidation of available data on the populations of B. laevigata subsp. gracilis and the locations. On the basis of the created area backdrop (actual number of existing populations), the supplementary merging of the information available on the use and funding measures previously carried out on the areas follows.
    2. Checking and recording of the current state of the area as well as the stock and threat situation of the individual populations in the area.
    3. Development of a specific protection and support concept based on the results of the research work and the site surveys.
    4. Exemplary implementations of direct species relief measures and indirect support measures for the maintenance or development of the locations of Biscutella laevigata subsp. gracilis.
