Two plastic visual barriers were ineffective in controlling expansion of 7 active black-tailed prairie dog (Cynomys ludovicianus) colonies and recolonization of 7 toxicant-treated sections of colonies. Barriers constructed with Sno-Strap, a 15.2- cm wide band of high-tensile polyethylene plastic, were destroyed by wind action within 3 weeks. Barriers constructed with Tensar® snowfence cost $2.10/m and retained their structural integrity for 3 years with occasional maintenance. Recommendations are provided to increase effectiveness of visual barriers.
