What is wildlife?
Wildlife is defined many ways. Some think of animals in a zoo. Others think of predators and prey – a hawk catching a mouse. Wildlife managers consider wildlife to be free roaming, naturally occurring species that live within nature’s system without significant influence by people. This section provides a brief introduction to the past, present, and future of Iowa’s wildlife.
Evidence of wildlife from prehistoric times is present in rocks that have been worn and weathered over millions of years.

Iowa’s Cultural History
Early Euro-American Explorers
Early explorers, who originally came from Europe to settle in America, ventured into Iowa for many reasons. Those that had well-documented expeditions sighted more than 450 species of vertebrates including white-tailed deer, beaver, wolves, bison, elk, black bear, passenger pigeons, prairie chickens, cranes, and swans.

Impact of Settlement
Many factors contributed to the destruction of much of Iowa’s native habitat and wildlife, however it began with Iowa’s settlement.

Changes in the Landscape

Introduced vs. Native Species
Iowa’s wildlife includes both native and introduced species. America’s first immigrants introduced many species of wildlife to North America. Non-native species (animals that did not naturally occur in an area) sometimes may compete with native wildlife for food, water, and shelter and can be more aggressive than native wildlife species (animals that naturally occur in an area).

Current Status of Wildlife in Iowa
Iowa’s wildlife has changed tremendously since Euro-American settlement (160 years ago). Many species have been extirpated. Others’ populations have dwindled to the point they now are listed as endangered. Still others have increased in number and range size. Many once extirpated have been reintroduced and now have stable populations. Wide ranging species (e.g., black bear, wolf, and mountain lion) occasionally reappear in Iowa as their populations in nearby states increase.
Iowa Department of Natural Resources: Threatened and Endangered – Current lists of all endangered and threatened species in Iowa can be downloaded. Page also includes definitions of endangered, threatened and species of special concern.
- Iowa’s Nature Series – Vertebrates – From city sewers to pristine prairies, the reptiles, amphibians, birds, mammals, fish, and lamprey found within Iowa’s borders are as diverse and fascinating as the people found there.
Iowa mammals belong to seven orders; carnivores (meat eaters), herbivores (plant eaters), omnivores (eat both plants and animals), marsupials (pouched mammals), insectivores (insect eaters), lagomorphs (rabbits and hares), rodents (gnawing mammals), and ungulates (hoofed mammals).
