i think it wrong to take gravid females from the wild. from us taking them from the wild that would become a decrease of the wild population and a increase of captive population. plus we need wild garter snakes they help reduce the population of mice,frogs,worms,fish and and many others. now if we were to keep taking garters from the wild there would be a major increase in the populations of mice,frogs,worms,and fish. and we couldn't release captive bred into the wild because they wouldn't know how to survive
