2.3.1. Analysis of Vegetation Data

We used the nomenclature for plant species according to [40]. Vegetation units (VUs) were formed by sorting the relevés in each growth by similar composition. The species in these VUs were sorted to form species groups. These groups show dominant species within the VUs. Four VUs were formed in the first growth, and three in the second. The plant species of a VU were listed in terms of their frequency to validate the separation into plant communities with the help of Ellenberg indicator values (EIV): soil moisture number (M, 1 = strong soil dryness, 5 = moist, 9 = wet, 12 = underwater), soil reaction number (R, 1 = extremely acidic, 5 = mildly acidic, 9 = alkaline) and nutrient number (N, 1 = least, 5 = average, 9 = excessive supply) [41]. The weighted means were calculated using the indicator values presented. The forage value, considering for example the protein and mineral content of the VUs, was determined using the values of [42].
