Cheatgrass: A Threat to Native Vegetation, Livestock, and Land Management
The Back 40 Team
What is Cheatgrass?
Cheatgrass (Bromus tectorum) is an invasive annual grass that has become a significant problem in rangelands, pastures residential areas across the United States. While it might not seem like much more than an unsightly weed, cheatgrass poses serious threats to native ecosystems, livestock health, and wildfire management. In this post, we’ll explore how cheatgrass outcompetes native vegetation, the dangers it creates, and effective methods for controlling it, including how our company can help manage cheatgrass while improving your pasture through our seeding services.
The Problem with Cheatgrass
Cheatgrass is a highly aggressive invasive species that thrives in disturbed soils and quickly establishes itself in areas where native vegetation struggles. Here’s why it’s such a problem:
- Outcompeting Native Vegetation:
Cheatgrass germinates earlier in the season than most native grasses and plants, giving it a head start in monopolizing soil nutrients, water, and sunlight. Its rapid growth and prolific seed production create dense monocultures that crowd out native species, reducing biodiversity and harming ecosystem health.
- Dangers to Livestock:
Cheatgrass can pose a direct hazard to livestock. Its sharp, barbed seeds can embed themselves in the mouths, nostrils, eyes, and skin of grazing animals, causing painful injuries and infection. This makes cheatgrass-infested pastures dangerous and costly for ranchers.
- Fire Hazards:
One of the most concerning characteristics of cheatgrass is its contribution to wildfire risk. By early summer, cheatgrass dies and dries out, leaving behind dense mats of highly flammable material. These dry grasses ignite easily and burn rapidly, increasing the frequency and intensity of wildfires, which can devastate both natural landscapes and human communities.
Strategies for Controlling Cheatgrass
While cheatgrass is a formidable foe, there are effective strategies for managing it. Here are some common techniques:
- Grazing or Mowing:
Heavy grazing or mowing in the early growing season can help reduce cheatgrass seed production. However, these methods provide only temporary relief and must be repeated regularly for continued suppression.
- Herbicide Applications:
The most effective way to achieve long-term control of cheatgrass is through the use of herbicides. Two key options include:
- Glyphosate (Spring Applications):
Glyphosate is a non-selective herbicide that can kill cheatgrass effectively when applied in the spring before the seeds mature. Importantly, glyphosate has no residual activity in the soil, making it an excellent option for use alongside pasture seeding. We can apply glyphosate to eliminate cheatgrass on the same day as we conduct seeding services, ensuring your pasture gets a fresh start without the risk of the herbicide affecting your newly planted seeds.
- Rejuvra (Fall Applications):
Rejuvra is a pre-emergent herbicide that provides long-term control by preventing cheatgrass seeds from germinating. Applied in the fall, this option targets cheatgrass before it can grow and spread, making it a valuable tool for proactive management.
- Glyphosate (Spring Applications):
