- Figure 7 Known endemic areas for Ixodes scapularis in Canada
Locations of known endemic populations of I scapularis are indicated by arrows. Areas where bird-borne adventitious ticks have been submitted by the public are indicated by the red circles: the larger the circles, the more ticks have been submitted.9 The western black-legged tick, Ixodes pacificus, is established in much of southern British Columbia.1 Small numbers of I pacificus and I scapularis, presumably carried by migratory birds, have been found in Alberta.9
