Grass recovers quickly after being grazed because it grows from the base rather than from tips.

The longer version

Growth in grass happens low down, at the base of each blade, in a region protected by the surrounding leaf sheaths. Removing the top of a blade therefore takes tissue that has already finished elongating and cannot regrow, while the growing zone below stays intact.

Because that zone sits close to or below the ground, it is also shielded from fire, frost, and trampling. The plant draws on reserves stored in roots and rhizomes to push out new blades quickly. Repeated close cropping does eventually exhaust those reserves, but recovery from a single event is usually fast.
