North American fields are a type of grassland habitat. Examples of grasslands include fields, amenity grassland (lawns and recreational fields), agricultural pasture, common land, and waste (grass) lands (Grassland habitats 2023).  Up to 2/3rds of a town or a city may be considered grasslands, and grasslands of all kinds encourage biodiversity along with social and even economic benefits (Grassland habitats 2023). Fields will typically have grass as their dominant vegetation, with the exception of agricultural fields (Grasslands Explained). Fields are often open and very flat and where there isn't enough rainfall to support the growth of an entire forest of a lot of other vegetation (Grasslands Explained). North American fields would be considered a temperate grassland (Grasslands Explained).
