Das Monitoring der Pflanzenarten der Anhänge II und IV der FFH-Richtlinie in Sachsen-Anhalt

KRUMBIEGEL, A.; FRANK, D.; ECKSTEIN, J.; HEIN, C.; KOMMRAUS, F. & MEYSEL, F. (2012): The monitoring of the plant species listed in Appendix II and IV of the Habitats Directive in Saxony-Anhalt. – Mitt. florist. Kart. Sachsen-Anhalt (Halle) 17: 3 – 24. A monitoring system for the plant species listed in Appendix II and IV of the Habitats Directive was installed due to the reporting obligation of Germany to the EU commission. In Germany the federal states are responsible for this monitoring. Actually there exist three localities of Angelica palustris, one of Apium repens, 107 of Cypripedium calceolus, 20 of Jurinea cyanoides, five of Liparis loeselii and five of Orthotrichum rogeri in Saxony-Anhalt. Monitoring sites have been installed at all these localities in 2011/2012 (for Cypripedium calceolus only 10, for Jurinea cyanoides 18). These plant populations were recorded and evaluated. Some species found in the last decade could not be found in 2011–2012: Coleanthus subtilis, Lindernia procumbens and Luronium natans. However, due to the naturally unstable presence of these species monitoring sites are installed at these localities as well. The three main criteria of the monitoring (situation of the population, habitat structure and impairments) as well as specific subcriteria and the monitoring frequency of these parameters are prescribed at the federal level. The specific monitoring of Saxony-Anhalt provides a partly more detailed programme, both concerning investigation criteria and frequency.
