The Mile High Back-Country Horsemen recently developed a checklist specifically for horseback riders who enjoy using public trails. "Some studies suggest that equine use on trails does little to spread noxious weeds, but let’s not become complacent in our efforts to insure that we are not part of the problem," said Charlie O’Leary, chairman of the Butte/Silverbow County Commission and a MHBCH member. Montana’s Statewide Noxious Weed Awareness and Education Campaign’s slogan is "Zero Spread," achieved through integrated weed management including cutting and mowing, hand pulling, herbicides, biological control, reseeding, grazing, cultivation and burning in some instances. Here are some of the steps O’Leary recommends that Montana horseback trail riders take to help Montana meet its goal of zero spread of noxious weeds.
