Fun Facts
Anolis sagrei is native to Cuba, the Bahamas, and a few other Caribbean islands. It entered the United States through Florida sometime in the early-to-mid 20th century, almost certainly via the plant trade — lizards lay eggs in the soil of nursery containers, containers ship north, eggs hatch at the destination, and nobody at the receiving end thinks to check a four-inch pot of tropical foliage for stowaways. That vector still drives most of the species' spread across the Gulf South. Plant nurseries receive stock from Florida operations where brown anoles are fully established, and…

The Invasive Lizard from Cuba That Already Owns South Louisiana, Is Currently Moving North, and Will Rearrange Your Yard's Reptile Community Without Asking
The brown anole did not ask permission to move into Louisiana. It arrived in Florida from Cuba and the Bahamas, spent a few decades establishing itself as one of the most successful invasive reptiles in North America, then worked its way west through the Gulf Coast states the same way it works its way into any new territory: fast, aggressive, prolific, and without any apparent concern for what was already living there. By 2002 it was common enough at the Audubon Zoo in New Orleans that a herpetologist noted it as unremarkable — something you mention as a footnote, not a finding. By 2010 it was showing up at plant nurseries in Lafayette. Monroe has recent documented records. It's coming, and it's not asking.
A Few More Facts
How they hunt and forage: The mechanism is behavioral competition rather than outright predation, though brown anoles do eat green anole eggs when they find them in soil and mulch. One egg in one pot is enough if conditions suit it, and North Louisiana conditions — warm, humid, insect-rich, full of suitable cover — suit it thoroughly. Reduced insecticide use that keeps the insect base available — losing the food supply hurts the green anole, which is already under competitive pressure, more than the brown anole, which adapts readily to lower prey density.
Live birth or eggs? no
When young are born: A hatchling that arrives in a Monroe nursery container in June can be laying eggs before the season ends.

Accessibility
Brown anoles flush faster and at greater distance than green anoles, making close approach difficult for anyone on foot. In south Louisiana where the species is fully established, slow drives through New Orleans or Baton Rouge neighborhoods on warm mornings give good views from vehicles without approach pressure. The species is dense enough in those areas that scanning low fence lines and sidewalk edges from a car window turns up animals constantly — sometimes before you've moved a hundred yards.
For visitors with limited mobility: the brown anole's preference for ground level, low walls, concrete, and fence bases means observation doesn't require elevated viewing, navigating uneven terrain, or looking into the canopy. Wherever the species is established, it uses paved and accessible surfaces as readily as natural ones. A sidewalk edge next to established landscaping in a south Louisiana neighborhood is as good a viewing location as anything a trail offers, and more reliable.
For visitors who are blind or have low vision: at ground level the brown anole's movement through leaf litter and across hard surfaces produces audible cues. The dewlap display — when a male extends and retracts his throat fan — produces a faint papery sound at close range. The species doesn't vocalize. A fully established population produces constant low-level movement noise across hard surfaces on warm mornings, which gives something to track even without visual confirmation.
Frequently Asked Questions
Does Brown Anoles live in North Louisiana?
Yes. If you're in North Louisiana and you've started seeing a lizard on your fence that looks brownish, stocky, and somehow wrong compared to the green anoles you grew up watching — it might already be here. Learning that distinction is useful now, before the brown anole becomes fully established across North Louisiana and the question stops being hypothetical and starts being just what your yard is. For North Louisiana yards, what this means practically: if brown anoles establish where you live, you'll probably still see green anoles, but you'll see them higher up.

Is Brown Anoles dangerous to people?
No. This species is not dangerous to people when it is observed without handling or disturbance
