What purpose do garter snakes serve in the ecological system?
Is there an environmentally safe way to prohibit them from "wandering" into yards and gardens?

The ecological "purpose" of any animal is probably best expressed as the question "what does it eat and what eats it?" Since garter snakes eat insects, you might actually welcome them in your garden. As an environmentally friendly form of pest control - they do not compete with us for food and therefore are not a pest in the economic sense. If you just do not like them you might consider erecting some kind of solid barrier to keep them out, or call your local animal control officer for advice.
