Answer: A predator species
Wildlife is plentiful in the piney woods and there are over 100 species of birds and many small mammals, like cottontails, rabbits and squirrels. All these species are relying for a same resource in order to maintain the population of these species a limiting factor is required which can cause elimination, extinction and migration of these species and limit their surplus population, hence maintain the balance of nature. A predator population can be a potent limiting factor here, as it can feed upon these species. Therefore, a predator species must be included in the piney woods habitat to keep population in balance.
