"The plight of tiny pupfishes, isolated in scattered springs and streams of the Death Valley System of California and Nevada for thousands of years, is a matter of national and even international concern. For some forms concern comes too late--they have already become extinct. The very existence of others is threatened by activities of man--appropriation of spring and ground waters, destruction of habitats, use of pesticides, and release of exotic species into these restricted aquatic habitats. In a brief span of several months or a few years at most, these species, too, may disappear if protective measures are not implemented immediately"--Foreword.
