Backyard Lizards in Southern California: A Comprehensive Guide

Southern California's sunny climate and diverse landscape make it a haven for various lizard species. Spotting these agile reptiles in your backyard is a common occurrence, adding a touch of wildness to your suburban setting. But knowing which lizards you're sharing your space with is key to understanding their behavior and ensuring peaceful coexistence. This guide will explore common backyard lizards in Southern California, offering insights into their identification, habitats, and behaviors.

Identifying Common Backyard Lizards

Several lizard species thrive in Southern California backyards. Correct identification is crucial, as some are more beneficial than others regarding pest control.

1. Western Fence Lizard ( Sceloporus occidentalis):

• Appearance: These lizards are easily recognizable by their characteristic stripes running down their sides. Their color can vary from brown to gray, with males often displaying vibrant blue coloration on their throat and belly during breeding season.
• Habitat: They prefer rocky areas with ample sunlight and vegetation for cover. Fences, rock walls, and woodpiles are common spots to find them.
• Behavior: Primarily insectivores, they are beneficial in controlling insect populations in your garden. They are generally docile and not aggressive towards humans.

2. Southern Alligator Lizard (Elgaria multicarinata):

• Appearance: These lizards are larger than fence lizards, with a robust body and keeled scales. They can range in color from brown to gray, often with dark stripes or markings.
• Habitat: They prefer areas with dense vegetation, often found under rocks, logs, or in brush piles.
• Behavior: Also insectivores, they play a vital role in controlling insect populations. They are less common in purely residential areas than fence lizards but can still be found in gardens bordering wilder areas.

3. Leopard Gecko (Eublepharis macularius):

• Appearance: While not native to California, leopard geckos are frequently kept as pets and sometimes escape or are released. They are easily identified by their spotted pattern and relatively docile nature.
• Habitat: They prefer dry, rocky areas, often seeking shelter under rocks or in crevices. If found in the wild, it's likely an escaped pet.
• Behavior: Primarily nocturnal insectivores.

4. Side-blotched Lizard (Uta stansburiana):

• Appearance: Smaller than fence lizards, side-blotched lizards exhibit distinct blotches along their sides, usually darker than their overall body color which can vary from light brown to greenish.
• Habitat: They prefer open, sunny areas with sparse vegetation. They're often found basking on rocks or in patches of sun.
• Behavior: Primarily insectivores, they're quick and agile hunters.

Creating a Lizard-Friendly (and Human-Friendly) Backyard

While lizards are generally beneficial, understanding their needs can help promote a harmonious coexistence.

• Provide Shelter: Leave some areas of your yard less manicured. Rocks, logs, and brush piles offer excellent shelter and basking sites.
• Maintain Vegetation: Native plants provide food and shelter for insects, the primary food source for many lizards.
• Avoid Pesticides: Pesticides can harm lizards and disrupt the delicate balance of your ecosystem. Opt for natural pest control methods instead.
• Water Source: A shallow dish of water can provide a crucial water source, especially during dry periods.

When to Seek Professional Help

While most lizard encounters are harmless, it's essential to know when to contact wildlife professionals:

• Injured Lizards: If you find an injured lizard, contact a local wildlife rehabilitator.
• Large Numbers: An unusually high concentration of lizards might indicate an underlying issue in your yard.
• Aggressive Behavior (Rare): While unlikely, some lizards might exhibit defensive behavior if threatened. Observe from a distance and avoid direct contact.

Conclusion: Embracing Backyard Biodiversity

Southern California's backyard lizards contribute to the rich biodiversity of the region. By understanding their needs and behaviors, you can create a welcoming environment for these fascinating creatures while maintaining a beautiful and safe backyard for your family. Remember, responsible coexistence is key to appreciating the natural world around us. Learning to identify and appreciate these reptiles adds a unique dimension to the Southern California experience.
