T
he first way to controlled the motivation of  toad is to build fence and it can somewhat limit the activities of toad.But the professor has sugguested that the fence can easily be took away by water,accompanied with toads' egg,then the hence will not work.
When it comes to gathering the power of volunteers to make some traps of capture toad by hands,is undeniable that this way can catch some of the toad.To the prefessor's worried,those untrained volunteers maybe could not distinguish cane toad from  native toad.As a result,some native toad may be killed by mistake.
