THREATENED WILDLIFE OF THE UNITED STATES
Introduction
General
This publication presents data on the status of species or subspecies of vertebrates whose
existence is threatened in the United States, the District of Columbia, Virgin Islands, and
the Commonwealth of Puerto Rico . Information is not yet available for American Samoa and
Guam. Two previous editions of this publication, entitled Rare and Endangered Fish and
Wildlife of the United States, differ from this third edition by substituting the designation,
"threatened," for the designation, "rare," or "endangered," in the data pages. This change
was made primarily to emphasize that the animals covered by data pages in this publication
do not comprise the official list of "Endangered" species . The latter is found in the U . S .
Department of the Interior's list of endangered native fish and wildlife, published in the
Federal Register. As did previous editions, this edition summarizes our knowledge of the
status of native vertebrates . It is intended to be a reference for compiling the official List
of Endangered Native Fish and Wildlife, as a means to stimulate interest, to impart know-
ledge, and to solicit information about threatened wildlife. It is likely that all pertinent
data are not included, and anyone who has additional information is encouraged to contact
the Office of Endangered Species, Bureau of Sport Fisheries and Wildlife, see Appendix A.
Only those animals determined by the Secretary of the Interior to be threatened with
extinction and named on the list which is published and amended periodically in the
Federal Register, are eligible for the benefits provided by the Endangered Species
Conservation Act of 1969 (16 U . S . C . 668aa) . Appendix C of this publication contains the
list as of the press date of this publication.
Only threatened vertebrates are included in this publication; mollusks and crustaceans
will be included in future editions . Within each of the five major Classes of vertebrates
(fishes, amphibians, reptiles, birds and mammals), families, genera and species are
arranged in phylogenetic order. This means that the most primitive or generalized forms
are considered first, followed by increasingly more advanced or complex types within
each'Class . This type of arrangement is recognized by scientists throughout the world.
In addition to the Federal program for endangered native fish and wildlife, many states
are adopting programs designed to prevent the extirpation of native wildlife found within
their borders . Information on animals considered endangered within the states may be
obtained, where available, by writing the appropriate state conservation agencies. Addresses
of those agencies are listed in Appendix B . A State-by-State listing of species endangered
nationwide is also included.
