How much can a jackrabbit eat in a day?

Hares consume 1/2 to 1 pound (1.1 to 2.2 kg) of green vegetation each day. Significant damage occurs when hare concentrations are attracted to orchards, gardens, ornamentals, or other agricultural crops. High jackrabbit populations can also damage rangeland vegetation. Eight jackrabbits are estimated to eat as much as one sheep, and 41 jackrabbits as much as one cow. Resources: (online) Jackrabbits
