Book excerpt: The accelerating encroachment of human activity on the natural landscape has made many citizens appreciate the need to save representative biotic communities before urbanization and technologically induced change eliminate such communities. Active programs in natural-area preservation are now in progress in the four basin states; these programs have strong public support and legislative mandate. Local, state, and federal agencies and private individuals have taken an active interest in protecting select areas as samples of the biotic communities and natural features of the Basin. Most natural areas described in this report have been dedicated or reserved in some fashion. Other areas are being added by the basin states each year. The maintenance of natural communities is closely linked to the preservation of endangered and threatened species of plants and animals which would cease to survive as isolated populations. Under federal regulations, certain plants and animals are listed as endangered or threatened in the Basin. As individual state lists are prepared and investigations proceed, it is probable that many more threatened species will be found.
