A common wall lizard hanging out between the rocks of my garden bed. 🦎 These lizards are invasive in BC and unfortunately a common sight in the greater Victoria area. Common wall lizards gather in large densities resulting in intense competition for food and habitat for BC’s native Northern Alligator Lizard and endangered Sharp-tailed Snake.
I do love seeing them run around our garden though. 🥹 Because they are so well-established in Greater Victoria, it’s hard to completely eradicate them from our properties, but we do need to prevent them from spreading into untouched natural areas.
Here’s how you can help protect BC’s ecosystems while still enjoying your garden visitors:
- Check your gear: Always inspect vehicles, campers, and boats for hitchhiking lizards or eggs before leaving the region.
- Check your plants: Look closely through soil, mulch, and potted plants before moving them to a new property.
- Support native species: If you have native alligator lizards around, leave large, heavy logs and deep brush piles where they can find safe shelter from wall lizards.
- Never relocate them to new parks, forests, or neighborhoods.
- Document your sightings on iNaturalist or the BC Invasive Species app. This helps scientists track how quickly the population is moving into new territories.
