What is the recommended minimum safe buffer zone when observing a rattlesnake?

At least six feet

Safe coexistence with native wildlife like *Crotalus molossus* requires maintaining a respectful distance to prevent inadvertent defensive reactions. For any encountered rattlesnake, including the black-tailed species, a general safety guideline suggests establishing a buffer zone spanning a minimum of six feet between the observer and the animal. This recommendation accounts for the snake's strike range, which, although variable and dependent on factors like body length, allows the observer sufficient distance to withdraw safely if the snake perceives a threat. Attempting to approach closely disregards this necessary safety margin and increases the potential for the snake to strike defensively.
