Monitoring of Vascular Plant Species from the Southeastern Part of Strandzha Nature Park, Bulgaria.

The study presents data on some invasive and conservation-significant species in two protected areas of the Strandzha Nature Park - Protected Area "Marina Reka" and Protected Area "Silistar". There were monitored the protected species Pancratium maritimum, Calluna vulgaris, Daphne pontica, Ilex colchica, Rhododendron ponticum, Mespilus germanica, and Taxus baccata, as well as an invasive species - Amorpha fruticosa, whose population borders that of Pancratium maritimum. The projective coverage of species in the sample areas and the total projective coverage of the vegetation have been studied also measures for their protection have been indicated.
