Extensive forests of uniform age or vegetative structure have dramatically fewer species than those with openings and aquatic habitats. For example: landscapes of unbroken mature forests have approximately 100 vertebrates; forest and early successional habitats, about 200; and forests with early successional and aquatic habitats, more than 300 vertebrates.
