Iowa has changed greatly since becoming a state in 1846. The prairies that helped develop the highly productive soils have been reduced by more than 99 percent. About 95 percent of the state's prairie pothole wetlands have been drained. Over half of the original forest has been lost. These changes and other factors such as channelization of streams and rivers, soil erosion, development and urban expansion, and intensive row crop agriculture have contributed to the loss or degradation of suitable habitat for numerous plant and animal species.
Individual species of plants and animals may contribute to the survival of other species within a community. The loss of what appears to be an unimportant species may result in the decline or loss of species that we consider to be very important. If we ignore species that are in danger of being extirpated from Iowa, we may be making decisions that cannot be reversed in the future. Conserving these species for future generations requires the coordinated effort by public agencies, private organizations, and property owners.
Iowa's endangered and threatened species law was enacted in 1975. The current law, entitled Endangered Plants and Wildlife is Chapter 481B of the Code of Iowa. The Natural Resource Commission and the Director of the Department of Natural Resources are responsible for administration of Chapter 481B.
