Spring Grazing: Timing and strategy for healthy pastures

Is your pasture really ready for cattle? Spring grazing is much more than a simple seasonal shift—it’s a strategic decision that can make or break the health of your pasture, the well-being of your herd, and your bottom line. In Episode 8 of The Bovine, brought to you by Alberta Beef Producers, host Kara Mastel sits down with David MacTaggart, Senior Agriculture Advisor with Strathcona County, to explore the art and science of spring grazing.

As MacTaggart emphasizes early on, producers can’t just rely on green grass as a signal to release the herd. Timing is everything. Spring pastures move through critical growth stages, from dormant winter residue to tender new shoots, and grazing too early can stress plants, deplete root reserves, and compromise pasture productivity for the entire year. He points out that letting grass reach the “three to four leaf stage” is a good rule of thumb to ensure plants have rebounded enough to handle grazing without long-term damage.

Another key takeaway from this episode is the importance of environmental stewardship. Thoughtful spring grazing can aid nutrient cycling, promote wildlife habitat, and preserve sensitive areas like riparian zones. However, without care, spring grazing can just as easily harm wet soils and degrade these vital ecosystems. MacTaggart shares useful strategies like rotational grazing and relocating salt and supplements to draw cattle away from vulnerable spots.

Of course, economic realities are never far from a producer’s mind. Spring grazing offers a welcome opportunity to reduce costly winter feeding expenses. But MacTaggart warns against sacrificing long-term sustainability for short-term savings. Particularly in drought-affected regions, resisting the urge to graze too early—even if forage is scarce—can make a huge difference in the future vitality of the pasture. In fact, giving grass extra rest in spring pays dividends later in the year, often leading to more grazing days in the fall.
