Why Hawaii Has No Native Snakes: Protecting a Fragile Ecosystem

Hawaii has zero native snake species. The islands’ extreme isolation prevented natural colonization by snakes.

Furthermore, the introduction of snakes is strictly prohibited by state law because they would pose an existential threat to Hawaii’s unique, fragile ecosystems—especially ground-nesting birds, many of which are already endangered.

Occasional stowaways (e.g., in cargo) are aggressively intercepted. The only snakes legally present are in permitted research or zoo facilities.
