Grassland in English include all types of land covered with grass. There are several words for this in French (pelouse, prairie, pré, herbage, gazon), but those terms are usually related with the land USE. I would like a single term that includes all the different land uses (natural grassland, pasture, garden...). Does such single word exist or should I use "formation herbeuse" or something similar.
Note : I am looking for this word in order to label a land cover on a map with herbaceous vegetation.
