In Lethbridge, the local rattlesnake handler, Ryan First Diver, has had a bustling year. He attends to 70% of the calls received through a hotline managed by the City of Lethbridge for residents who spot snakes on public grounds. These snakes are relocated from public areas to their natural habitats, including den sites, wintering spots, or birthing grounds.
This year, a total of 211 snakes have been relocated, encompassing various species like rattlesnakes and bullsnakes, which are non-venomous constrictors often mistaken for rattlers. Described as an “all-time record” by First Diver, this figure surpasses previous relocation numbers.
City bylaw officer Dave Henley mentioned that Lethbridge typically fields 150-160 snake-related calls annually. First Diver credits increased public awareness about snakes to his social media posts, which initially spiked call volumes but have now stabilized. Residents are now actively sharing snake safety tips online.
Contrary to common beliefs, rattlesnakes are not inherently aggressive, as highlighted by First Diver. He emphasized that maintaining a safe distance from the snakes is key, as they do not typically approach humans unless provoked. Rattlesnakes rely on camouflage and prefer to avoid confrontations, only striking when cornered or threatened.
Stefano Liccioli, a senior biologist, debunked misconceptions about rattlesnakes, emphasizing that no deaths from rattlesnake bites have been recorded in Alberta. He stressed that rattlesnakes bite defensively and mainly to feed, rather than out of aggression.
The increasing number of snake-related calls in Lethbridge suggests a potential rise in the local snake population, prompting ongoing studies by environmental authorities. By tagging snakes with transmitters, researchers aim to track their movements and identify den locations for better conservation strategies.
In the next five to ten years, comprehensive data on Alberta’s rattlesnake population trends is expected to shed light on their responses to environmental pressures and guide future conservation efforts. Understanding these trends will help determine if additional protective measures are needed for these important reptiles.
