Overview
Lizards may not be the first creatures that come to mind when you think of Canada, but this vast country is actually home to several lizard species.
In this article, we will explore the different lizard species found in Canada, their distribution and habitat, behavior and characteristics, as well as the misconceptions and sightings associated with them.
Native Lizard Species
Northern Alligator Lizard
One of the native lizard species found in Canada is the Northern Alligator Lizard (Elgaria coerulea).
These lizards are primarily found in British Columbia and are known for their distinctive blue coloration. They inhabit a variety of habitats, including forests, woodlands, and even suburban areas.
Northern Alligator Lizards are often seen basking in the sun or hunting for insects and other small prey.
Eastern Fence Lizard
Another native lizard species in Canada is the Eastern Fence Lizard (Sceloporus undulatus). These lizards are primarily found in southern Ontario, especially in areas with rocky outcrops and open woodlands.
Eastern Fence Lizards have a unique fence-climbing behavior and are often seen perching on fences, walls, or tree trunks.
They feed on a variety of insects and play an essential role in controlling pest populations.
Five-lined Skink
The Five-lined Skink (Plestiodon fasciatus) is a small, colorful lizard species found in various parts of Canada, including Ontario, Quebec, Nova Scotia, and New Brunswick.
As the name suggests, these skinks have five distinct lines running along their bodies. They are usually found in moist habitats, such as forests, meadows, and near rivers or streams.
Five-lined Skinks are excellent climbers and feed on insects, spiders, and small invertebrates.
Prairie Skink
The Prairie Skink (Plestiodon septentrionalis) is primarily found in the prairies of southern Alberta, Saskatchewan, and Manitoba.
These lizards are well-adapted to the open grasslands and can often be spotted basking on rocks or logs.
Prairie Skinks are insectivorous and play an important role in maintaining ecological balance by controlling pest populations.
Introduced Lizard Species
Green Anole
While most lizard species in Canada are native, there are a few introduced species that have established populations in specific regions.
One such species is the Green Anole (Anolis carolinensis), native to the southeastern United States. Green Anoles were introduced to Vancouver Island in British Columbia through the pet trade but have since become established in some urban areas.
They are commonly found in gardens and parks, where they feed on small insects.
European Wall Lizard
The European Wall Lizard (Podarcis muralis) is another introduced species in Canada. These lizards are native to Europe and were accidentally introduced to the Greater Vancouver area in British Columbia.
They are known for their ability to climb walls and are often seen basking on rocks or buildings. European Wall Lizards are omnivorous, feeding on insects, spiders, and plant matter.
Misconceptions and Sightings
Misidentification of Other Species
There have been numerous reports of lizards sightings in Canada that turned out to be misidentifications of other animals.
Many snake species, such as the Northern Watersnake, Garter Snake, or even young Bull Snakes, have been mistaken for lizards due to their elongated bodies and scaly appearance.
It is important to consider other factors, such as habitat, behavior, and physical characteristics, when identifying lizards in the Canadian wilderness.
Rare Sightings and Escaped Pets
Although native and introduced lizard species have established populations in certain regions of Canada, sightings outside of these areas are relatively rare.
However, there have been occasional reports of escaped pet lizards, such as Green Iguanas or Bearded Dragons, being found in unanticipated locations.
These sightings serve as a reminder of the popularity of keeping lizards as pets and the risks associated with their release into the wild.
Conservation Status
Threats and Conservation Efforts
Lizards in Canada face various threats that impact their populations and habitats. Factors such as habitat loss, fragmentation, and degradation due to urbanization, agriculture, and deforestation pose significant challenges for their survival.
Climate change is also a growing concern, affecting lizard populations by altering their habitats and disrupting their reproductive cycles.
Efforts are being made to conserve and protect lizard species in Canada. Conservation organizations work towards raising awareness about the importance of lizard conservation and implementing measures to preserve their habitats.
These efforts involve promoting habitat restoration, establishing protected areas, and conducting research on lizard populations to better understand their needs and conservation requirements.
Research and Monitoring
Research and monitoring play a crucial role in understanding lizard populations in Canada. Scientists study various aspects of lizard biology, including their behavior, diet, reproductive patterns, and response to environmental changes.
Monitoring programs help track population trends, detect early signs of decline, and provide valuable data for conservation planning and management strategies.
Protecting Lizard Habitats
Protecting and preserving lizard habitats is vital for their survival. This includes conserving intact natural areas, creating wildlife corridors to connect fragmented habitats, and implementing sustainable land-use practices that minimize habitat destruction.
Additionally, public education and awareness initiatives are essential in fostering a sense of stewardship and encouraging individuals to protect and appreciate lizard habitats.
Lizards in Canadian Provinces and Territories
Lizard species in Canada are distributed across several provinces and territories. Let’s take a closer look at where these reptiles can be found:
