Record Rattlesnake Removals in Lethbridge
The City of Lethbridge has experienced a record-breaking year for rattlesnake removals. By October 8, officials had relocated 211 snakes, surpassing typical figures for the municipality’s renowned rattlesnake mitigation program. These removals include not only rattlesnakes but also species such as bullsnakes, which can be confused with rattlers due to their appearance.
Overview of the Rattlesnake Mitigation Program
Lethbridge has operated a rattlesnake mitigation program for about 30 years. The program's aim is to move snakes found on public property to safer, natural habitats such as dens, wintering grounds, or birthing areas. Residents concerned about snake encounters can contact a city-run hotline, and trained professionals respond to these calls throughout the city.
Community Involvement and Snake Awareness
Ryan First Diver, a prominent member of the snake relocation team, handled approximately 70 percent of snake-related calls this year. First Diver said that increased social media posting and public discussion have made residents more aware of snakes and know how to respond appropriately. As snake awareness grows, people are using online platforms to educate each other about safe behavior and where to watch for snakes.
Debunking Myths about Rattlesnake Behavior
Despite common misconceptions, experts emphasize that rattlesnakes are not aggressive toward humans. First Diver points out that rattlesnakes rely on camouflage when people are nearby and are unlikely to approach unless provoked. He reports that he typically wears shorts and sandals during relocation work without incident, keeping a safe distance from the animals. Stefano Liccioli, a senior species-at-risk biologist with Alberta Environment and Protected Areas, adds that rattlesnakes only bite when cornered or stepped on, and there have been no reported fatalities from rattlesnake bites in Alberta. Their defensive strikes are rare, and their primary motivation for biting is to secure food.
Possible Increase in Local Snake Populations
The record number of removals may indicate a growing snake population or heightened awareness and reporting from Lethbridge residents. Calls have come from areas where snakes were not previously observed, which could point to expanding snake activity or the presence of new dens. While more than 100 prairie rattlesnake dens are known in Alberta, the provincial population trends remain unclear.
Ongoing Snake Conservation and Research Efforts
Efforts are underway to better understand snake population dynamics in Alberta. The City of Lethbridge’s program, in collaboration with Alberta Environment and Protected Areas, has begun tagging some rattlesnakes with small transmitters to track movements and identify unknown dens. This research aims to provide comprehensive data about rattlesnake populations over the next five to ten years, helping refine conservation and wildlife protection strategies as needed.
