  Vanishing Species Management  

What is being done to manage these species?

The ways plants and animals are managed by land owners and biologists differ with each species. The number of individuals present is an important factor in developing a management plan. Managers may also consider the economic importance of the plant or animal to people. This factor includes the value of the species as a food resource, such as fish, wild turkey and white-tailed deer, that many people harvest and eat. Wood products that we use in our home and school are also economically important.

In some instances resource managers may reintroduce a species. Prairie chickens, white-tailed deer, wild turkeys and river otters have been captured in areas where their populations are healthy and released into suitable Illinois habitats.

Management of the habitat may make the area more suitable for a plant or animal. To improve a habitat, biologists may recommend prescribed fires, timber cutting, removal of exotic species, reflooding a historic wetland or restricting human use of an area. In many cases, the best action is no action. By having the area develop naturally, many plants and animals will return.

Biologists conduct research on endangered and threatened species to learn more about the food, water, cover and space they require to survive. From this information, plans can be made to improve habitats for these rare species.
