CONSIDERATIONS ON PLANTS AND ECOSYSTEMS DIVERSITY, AND CONSERVATION WITHIN FOUR LOCATIONS ALONG THE RIVER MUREȘ PUBLISHEDDaciana TURCUŞ, Iulia Natalia DĂRĂBAN
This study was conducted in four sites (each of 3x3 km) along the river Mureș in Arad dept. All plant (cormophytes) species were recorded in search of correlations with the land use categories. We consider 14 categories of land use. The total number of cormophyte species is 369, with vlues per location from 197 (Felnac) to 265 (Vladimirescu). The proportion of (semi-)natural ecosystems is not strongly correlated with a higher plant diversity, as well as the proportion of agricultural fields is not correlated with the number of weed species (variation from 57 to 79). There is no difference in the number of invasive species per location (variation from 12 to 16 species). Amorpha fruticosa is the most important (by occupied area) species. Further studies are needed in order to have a better estimation of agricultural practices influence on natural biodiversity and to increase the tenability of biodiversity management, especially within the Lunca Mureșului National Park.
