The answer is either -unfenced land where grass or grass-like vegetation grows and is the dominant form of plant life, or <span>-an enclosed field covered with grass or similar plant and suitable for grazing by livestock.
I am not sure which though.
I hope this helps you!
Have a nice day! :)</span>
