Mammals
Mammals have several distinct characteristics that distinguish them from other animals. Like other vertebrates, they have a flex­ible backbone or vertebral column, which supports their body and protects the extensive nerve system of the spinal cord. All mam­mals have hair, which serves as an insulator to retain body heat and ward off cold.

Most Oklahoma mammals are completely fur-covered, though others display only sparse patches of hair. Mammals are warm­blooded (homeothermic - body regulates its internal temperature) and have a four-chambered heart that circulates but completely separates oxygen-rich and oxygen-poor blood.

Since mammals can maintain a constant body temperature inde­pendent of surrounding temperatures, they can endure most envir­onmental conditions and are found in a wide range of habitats.

Another primary characteristic is that mammals bear their young alive and nourish developing offspring with milk produced from mammary glands, from which the class Mammalia receives its name.

In proportion to body size, mammals have large brains sur­rounded by a prominent braincase.

In contrast, mammals differ in many ways, too. They use a vari­ety of forms of locomotion: they can fly, glide, swim, run, leap, climb and burrow. They can either be predator or prey and may feed on meat (carnivores), plants (herbivores), or both (omnivores).

Mammals prefer different habitats, too. Some species are under­ground dwellers, whereas others choose to live on land, in water or trees. Some species are so versatile they can use any habitat from the arid, sparsely vegetated land in western Oklahoma to the more humid, forested regions of the southeast.

Mammals developed from reptilian ancestors 200 million years ago. The adaptations that made these animals successful have been refined by natural selection as vegetation and climate have changed in response to major geologic changes.

Mammals and humans share an important relationship - since we're mammals, too. Man relies on wild and domestic animals for food, fur, leather, bone, oil, perfume, fertilizers, chemicals and medicine. And hunting and trapping game and furbearing mam­mals provide many recreational opportunities and substantial revenue, particularly in rural areas. Watching and photographing mammals provides many hours of enjoyment for other outdoor enthusiasts.

Except for members of the squirrel family, most mammals tend to be nocturnal and secretive. The diversity of mammals, due to Oklahoma's variable climate, vegetation and habitat types, and geography, may surprise you.

Wildlife management
Over six decades ago, wildlife management was borne out of a concern for animals and their habitats, the deple­tion of game spe­cies, and a recognized need for responsible management of human activities. Many current concerns about global wildlife and environmental health were discovered be­cause of efforts to save species from extinction. As our understanding of the relationships between the earth, wildlife, and humans has increased, the management of wildlife and wild lands has im­proved dramatically.

Wyoming has more than 600 spe­cies of birds, mammals, fish, reptiles, amphibians, mollusks, and crusta­ceans. Much of the evolution in management and habitat protection resulted from experiences with rare, threatened, and endangered wildlife.

The Wyoming Game and Fish Department is assisting in the preservation of val­ued wildlife in the state and nation by protecting and managing habitats. When the environment of an animal is healthy, it allows that animal to sur­vive on its own. Maintenance of habi­tats allows each community to exist as a self-sustaining system with little, if any, human intervention.

We should be con­cerned with healthy ecosystem because the decreases in some animal or plant populations indicate harmful elements in our environment, elements which also affect humans. The more stable and diverse an ecosystem is, the more durable its wildlife popu­lations will be.

As an example, there has been a decline of many neotropical migrant birds that rely on nesting habitat across North America. Fifty-four percent or 133 of the 246 avian species that nest in Wyoming migrate south and rely on rain forests and other southern latitude habitats. Declines in some of these species have been caused, in part, by changes along migratory routes and breeding habitat here in Wyoming and elsewhere. Another cause of these de­clines has been the loss of winter habi­tat in the shrinking rain forests of Cen­tral and South America.

Tropical rain forests not only affect Wyoming bird life, but they are important because they provide oxygen, contribute to the water cycle, and maintain the most diverse systems on earth. Rain forests may also influence global temperatures. The loss of neotropical migrants is an indicator of the plight of the rain forest.

Our accumulated knowledge has taught us that all living things on earth are interconnected. Humans need food, shelter, and water as much as any other living thing. Man is the only species which can alter the habitat and ultimately affect the destiny of all life.

We have a great need to maintain a healthy, diverse world, not only for wildlife, but for ourselves. This means maintaining a wild home for all of our existing wildlife and improv­ing or increasing habitat for our rarest wildlife populations. It means solving environmental problems that exist to­day and making responsible decisions for preserving future environmental quality.
