you are correct carolyn the ramp has a bulb like a tiny onion. it has always been my understanding that you should cut the ramp leaf and not pull the plant out with the bulb included. if you cut the leaves the bulb remains and regrows otherwise you yanked the plant out and it won't be there next year. ramps grow in patches so when you find them it looks like there are a lot but i'm always careful to insure the plants will be there next year.
all that said, i stopped picking ramps several years ago. ct is infested with ticks so i don't go into the woods and avoid leaf litter. this pretty much precluded picking ramps.
one day in april while driving down a dirt road i spotted ramps close to the road. i was able to stand on the road and not get into the leaf litter so i picked some leaves being extra careful to not get down in the leaf litter. i drove off eating a leaf enjoying the great taste when i felt a tickling on my hand. i took my eyes off the road to look and sure enough there's a dog tick (not the tiny deer tick) walking across the back of my hand. fortunately i was able to pull to the side of the road and stop immediately, jump out of the car and get that ^*#@(*& tick off me. i tossed all the ramp leaves out of the car. this was the last time i ever ate ramps in this life time.
