This Grazing Season, Remember the Four Principles of Pasture Management

Pasture is a key component of beef cattle operations and one definitely worth managing. At first glance, grazing a pasture may appear as simple as placing cattle in a fenced area with a water source. However, practising effective grazing management is an art and a science.

Pasture conditions and types vary widely from native grassland to tame forage, with stands comprised of many diverse plants or perhaps just a simple mixture of a few grass or legume species. Regardless of the pasture type, focusing on a few key principles can help maintain forage productivity, ensure stand longevity, sustain a healthy plant community, conserve water, and protect soils. Here are four main factors to remember:

  • Balance forage supply and livestock demand. Avoid overstocking a pasture by ensuring there is adequate forage available for the number of cattle, and the length of time, the cattle will be grazing. BCRC’s Carrying Capacity Calculator can help producers determine a starting point for their stocking rates. In addition to grazing, remember to factor in a utilization rate to account for trampling, wildlife, or insects. General guidelines for native pasture suggest a utilization rate of 25-50%, and for tame pasture a utilization rate of 50-75% is a built-in buffer that allows the pasture to sustain itself.
  • Distribute grazing pressure across the pasture. When left on their own, cattle will prefer to graze moist, productive areas of a pasture and avoid dry hilltops where the forage quality may be lower. Cattle can be managed to graze a pasture in a relatively uniform manner using different methods depending on forage type, topography, and goals. Temporary or permanent fencing, placement of salt and mineral, and stock water locations can all be strategically maneuvered to effectively move cattle. Working with available resources is important, as outlined in this recent blog and webinar about adaptive grazing management.
  • Provide rest for pasture plants during the growing season to help plants recover. Forage plants need time to rest to allow them to replenish their energy reserves and prepare for the next grazing event. If plants don’t have adequate time to recover, pasture productivity can dwindle, and pastures can become susceptible to weed infestations, soil erosion and winterkill.
  • Avoid grazing during sensitive times. Grazing too early can set a pasture back for the whole season. A general rule of thumb is for every day grazing is deferred in the spring, you gain two days of grazing in the fall. Other situations such as grazing wetlands or species at risk habitat, may benefit from deferring grazing until nesting season is over or flood potential has subsided.


Litter is often called a “rancher’s insurance policy” because it helps pasture systems retain moisture in dry years and can help maintain forage yields.

Manage pastures to retain adequate “litter” cover. Litter is the dead or decaying plant residue left from previous growing seasons and it is a valuable resource in both tame and native pasture stands. Litter insulates the soil, keeping it warm in the winter, and cool in the summer. As it breaks down, litter provides nutrients to the surrounding plants, and it is a wonderful safeguard for reducing soil erosion and water loss due to evaporation.



There are many different types of grazing systems promoted by groups and individual producers, including, but not limited to, rest-rotation, AMP (adaptive multi-paddock), intensive, or strip grazing.  While each system has its own benefits and drawbacks, almost all systems factor in the four key principles of grazing management. By carefully managing pasture as the valuable resource that it is, forage production and range health can be sustained for this season, and for many years to come.
