The productivity of the grasslands is determined by the biodiversity of the plant species present in the vegetation, their quality, but also their exploitation. For their inventory, a series of determination methods are used, methods that are difficult to manage and that require a good knowledge of the plant species. For an agronomic characterization of the plots, it is sufficient to consider only the main species that dominate the plant biomass. A more simplified method is that of botanical surveys which focus only on recognizing the dominant grasses in grasslands. This method allows for an agronomic diagnosis of a grassland without modifying the variables studied, namely, the percentage of biomass participation and the percentage of each functional type of grasses. The method allows the application of a functional typology that can estimate the value of use (forage quality, productivity, precocity or lateness) of a grassland.
The purpose of this work is to classify the species by plant families, establish the pastoral value and inventory the grass species, as well as classify them from a morphofunctional point of view, in order to implement some management strategies aimed at ensuring an optimal exploitation of the grasslands taken into study.
The measurements were made on three grasslands belonging to the town of Sasca Montana, Romania, located in the south of the Western Carpathians (44°53'13"N 21°42'33"E), at an altitude of 237 m. In this area, the average annual temperatures is between 9 - 10°C, and the precipitation level is between 700 and 800 mm. The three studied grasslands have a similar floristic composition, but with a different participation percentage of species. The dominant grass species, from a morpho-functional point of view, are species of type C (Festuca valesiaca being the dominant species), which shows that these grasslands are weak and do not adapt to mowing practices, although the species included in this morpho-functional type are species with a fairly good fodder value in the vegetative phase.
