Hillside burrgrass
Cenchrus caliculatus Cav.
Cenchrus australis, commonly known as buffelgrass, is a species of grass native to Africa, Asia, and the Middle East. It has been introduced to various regions worldwide for forage and erosion control purposes. Please note that information provided here might not reflect recent developments or research.

Description: Buffelgrass is a perennial grass that exhibits characteristics adapted to arid and semi-arid environments. The plant typically grows in clumps and can reach heights of 3 to 4 feet (1 to 1.2 meters). The leaves are long, narrow, and rolled, with a distinctive gray-green color. The inflorescence, or flowering part of the plant, forms a cylindrical or spikelike structure with densely packed spikelets.
Habitat: Cenchrus australis is well-suited to a variety of habitats, including grasslands, savannas, and open woodlands. Its adaptability to different soil types and resistance to drought make it particularly well-suited to arid and semi-arid regions. Buffelgrass has been introduced to regions around the world for soil conservation, erosion control, and as forage for livestock.
Ecological Impact: While buffelgrass has been beneficial in some contexts, its introduction to new areas has raised concerns about its ecological impact. In regions where it has become invasive, buffelgrass can outcompete native vegetation, leading to changes in ecosystem dynamics. The grass's ability to form dense stands can alter fire regimes, making fires more frequent and intense, which poses a threat to native plant and animal species not adapted to such conditions.
Uses:
- Forage: Buffelgrass is widely used as forage for livestock, particularly in areas with low rainfall and limited grazing resources.
- Erosion Control: The grass has been introduced to control soil erosion due to its ability to establish quickly and form dense root systems.
- Land Reclamation: Buffelgrass has been used in efforts to reclaim degraded lands and improve soil fertility.
Challenges: The invasive nature of Cenchrus australis in certain regions highlights the importance of carefully assessing and managing the introduction of non-native species. Efforts are underway in some areas to control and manage buffelgrass to mitigate its negative impacts on local ecosystems.
