SCREENING ON SOME PERMANENT GRASSLANDS IN TIMIS COUNTY (WESTERN ROMANIA). CASE STUDY

Abstract

The grass of the grasslands is the most accessible source of food for herbivores during a significant period of a year. The knowledge of the floristic composition of grasslands reflects the current state and is an essential element in determining the load of animals. This paper is a case study and aims to inventory the species participating in the grass cover near some localities in Western Romania. Vegetation surveys were made in March, June and the first quarter of October. The study method by which the vegetation was determined is the linear method on the basis of which different indices could be calculated such as: specific frequency, biodiversity index, pastoral value. The obtained results led to the conclusion that the analyzed permanent meadows are classified as mediocre in terms of forage, the pastoral value expressing these aspects. Regarding the biodiversity of the analyzed grasslands, it is classified as medium and high in one of the cases. Based on the analysis of these results, respectively their correlation with the mode of intervention on these permanent grasslands, the possible evolutionary trends of the vegetation and its direction can be outlined in order to improve the economic value and the species richness.
