Stipa curtiseta
Western Porcupinegrass
Western Porcupinegrass is a native perennial bunchgrass that thrives in dry, arid environments, such as deserts and semi-arid grasslands. It is known for its distinctive seed heads with long, sharp awns that resemble porcupine quills. While not a preferred forage species for livestock due to its coarse texture and low palatability, it can provide some grazing value, especially for drought-tolerant animals like sheep and goats. Western Porcupinegrass is highly drought-tolerant and plays a crucial role in stabilizing soils in arid regions, reducing erosion and improving soil health. It also provides valuable cover and food for a range of wildlife species, including birds and small mammals.
