Answer:
by collecting and removing the snakes from the Everglades
Step-by-step explanation:
One effective way of controlling population of an invasive specie is by removing the invasive species from the everglades. Since the snakes eat a certain specie of birds, they endanger that specie of birds and their increasing number may make the bird specie to become extinct.
By so doing, scientists will have effectively controlled the invasive specie of snakes in the everglades.
