Buffelgrass (Cenchrus ciliaris: Poaceae)
Meet Buffelgrass, one of the most aggressive invasive species currently taking over Central, South, and West Texas. While it originally hails from Africa and serves as a decent forage grass for livestock, it’s a disaster for our native ecosystems.
In this video, we take a closer look at the difference between a young plant and a mature one in anthesis. Notice those distinct purple, basket-shaped spikelets covered in soft, bristly awns. While it's recently been moved into the Cenchrus genus (the same genus as those dreaded stickerburrs), these spikelets are actually soft and won't hitch a painful ride in your socks.
To really identify this in the field, look for the internodes (the stem segments), which are almost entirely hidden by overlapping leaf sheaths. If you try to pull it up, you'll feel just how tough it is; the plant grows from a knotty, rhizomatous base that allows it to anchor deeply and survive extreme drought.
Buffelgrass completely alters the hydrologic cycle and crowds out the native forbs and grasses that our wildlife depends on. Whether you're in downtown San Antonio or out on the open range, it's important to identify this invader and manage it before it takes over your land completely.
