摘　　要：Over the past decade,extensive poisoning campaigns have been conducted in southern Saskatchewan to control Richardson’s ground squirrel Spermophilus richardsonii(Sabine,1822)populations.Such campaigns might impact on predator abundance by decreasing prey levels,and also through secondary poisoning.Using spotlighting,we investigated the relative abundance of American badgers Taxidea taxus(Schreber,1777)and red fox Vulpes vulpes(Linnaeus,1758)in 2 study areas with road access and crops,but with different levels of poisoning.In the study area with relatively low poisoning(19.6%of the area traversed by roads),there were 2.2 times more American badgers per km of road and 6.4 times more red foxes per km than in the study area with high poisoning(89.7%of the area).It is recommended that an Integrated Pest Management program be developed to conserve natural predators across landscapes.
