Judging whether forage is overgrazed or undergrazed can be a tough call. Ideal grass height should not exceed 6 to 8 inches at the start of grazing and should not be grazed down to less than 2 to 3 inches, say some experts.

Undergrazing pitfalls:

  • Shades out low-growing forage species
  • Produces stems of low quality
  • Reduces forage production with soil capping

Overgrazing pitfalls:

  • Lose desirable species
  • Lowers carrying capacity
  • Slows root growth
  • Reduces drought tolerance
