As one might suspect, graminoids (grass-like species) are the dominant vegetation type in tall, mixed and short grass prairie habitats. They comprise 25 - 100% of the vegetation cover in dry prairies and 75 - 100% of the cover in medium to moist prairies. Forbs (wildflowers), on the other hand, comprise only 5 - 50% cover of any prairie type. The diversity of grass species, on the other hand, is far lower than forb species. As an example, on the Manitoba Tall Grass Prairie Preserve there are around 27 grasses and well over 300 forbs.
