Dekay's Brown Snake is one of the most abundant and widespread snake species in eastern and central North America, and it is not listed as threatened or endangered at the federal level in either the United States or Canada. However, state and provincial protections may still apply depending on the jurisdiction. Some states include brown snakes in their general protections for native wildlife, which may restrict collection, possession, or killing of the species even though it is not formally endangered.
In certain states, all native reptile species — regardless of abundance — receive blanket legal protection that prohibits collection without a permit. In these jurisdictions, picking up a brown snake from your garden and placing it in a terrarium without a wildlife possession permit could technically constitute a violation. The intent behind these broad protections is to prevent habitat degradation and overcollection across all native species, not just those at immediate risk of decline.
At the northern edge of its range, particularly in parts of Canada, the brown snake may receive additional conservation attention. Some Canadian provinces have included Storeria dekayi in their lists of species of conservation concern, which can trigger habitat protection measures and monitoring requirements. These designations reflect the species' relative scarcity and vulnerability at the periphery of its range, even as core populations remain robust.
Prospective keepers and anyone encountering brown snakes in the wild should consult their local wildlife agency for the most current regulations. Wildlife law is dynamic, and protections can be added or modified as new population data becomes available. The fact that a species is common does not necessarily mean it is unregulated, and assuming otherwise can lead to unintentional legal violations.
