SUDIES CONCERNING FLORA FROM DIFFERENT PROTECTED AREAS IN CONSTANTA COUNTY BY APPLYING ECOLOGICAL AND STATISTICAL METHODS

This study presents our results concerning the geographical distribution, ecological and anthropic impact aspects of the wild flora from three protected areas (Fantanița Murfatlar, Gura Dobrogei and Hagieni forest). All three nature reserves studied belong to the Natura 2000 European network protection. From this point of view we watched the current state and future premises on the maintenance of vulnerable species / endangered in the natural habitats. The study is based on monitoring for 3 years (January 2015-December 2017), in which we identified: main plant families, distribution of species in geoelements and analysis of ecological categories (moisture factors, temperature and soil reaction). For a better tracking of the similarities between species in three distinct areas, we used the statistical method of processing data. The results showing important similarities between the three types of protected areas with respect to the balance of positive and negative effects using Pearce coefficient and respectively with respect to structure and function of natural biota.
