TINKER AIR FORCE BASE, Okla. --
A nefarious enemy has found its way to Tinker Air Force Base, but there is no cause for alarm as this enemy is a weed.
The Musk Thistle, sometimes called the nodding thistle, is an aggressive and invasive noxious weed from the sunflower family that is a prolific seed producer. That may not seem too distressing, but according to Natural Resources technician Donna Nolan, one plant can produce up to 20,000 seeds, and the seeds can stay active in the ground for many years.
This is the first time the thistle has been found on Tinker.
“Many states, to include Oklahoma, have declared the Musk Thistle a noxious weed, and it is mandated that land owners must mitigate the spread of this weed or may face fines or imprisonment, or both,” said John Krupovage, Natural Resources manager. As a Federal Reserve, Tinker must comply with the Federal Noxious Weed Act.
Krupovage added that livestock won’t graze in areas of heavy infestation of the spiny thistle that crowds out the desirable forage plants.
“We want to be responsible land stewards and good neighbors, so at the first discovery of the weed, the Natural Resources team and base haying lessee immediately began to mitigate the spread,” said Krupovage.
Since the weeds are not long-lived perennials, they don’t need to be pulled up by the roots. The team can just use an axe or machete and chop them down by hand as long as they are cut low enough to prohibit regrowth. The cut plants must be removed from the field and properly disposed.
The plant itself has a large rose-purple flower shaped like a ball that droops. After the flower fades, seeds are released and scatter in the wind, invading and contaminating surrounding land.
If anyone comes across this plant, Nolan warns not to touch it. She speaks from experience when she says the spines on the plant cause unpleasant irritation to the skin. The plant has spiny leaves and may have some fine hairs on the underside of the leaves.
Call the Natural Resources office at 739-7074 if you spot this weed on base, so it can be removed safely.
