publications, and conservation organization 
reports. Unpublished material has generally 
been excluded except for university theses and 
dissertations, and Federal Aid ("Pittman- 
Robertson") reports on file with the Fish and 
Wildlife Reference Service (FWRS), Denver Pub- 
lic Library. 
Book titles were located in the Subject 
Catalog of the Library of Congress Catalog. 
Published journals were searched through Wild- 
life Review, Zoological Record, Applied Ecol- 
ogy Abstracts, and Biological Abstracts (by 
BIOSIS = on- Tine computer search). Manual 
searches were made of the contents of the 
Journal of Wildlife Management, Journal of 
Mammalogy , and the Auk. Relevant bibliogra- 
phies of published material were located in 
the Bibliographies Index and the index to the 
Council of Planning ‘Librarians Exchange Bibli- 
ography ‘Series. Government publications were 
located in the Monthly Catalog of U.S. Govern- 
ment Publications and computer searches of the 
FWRS collections were carried out. Disserta- 
tion Abstracts International was searched for 
Ph.D. Dissertations. Because literature on 
nonconsumptive recreational activities and 
wildlife is often concealed as short sections 
of reports dealing with other topics, we used 
literature cited sections of reports already 
located in addition to the indexes and bibli- 
ographies searched. 
The citations are listed alphabetically by 
author and include annotations and descrip- 
tors. Style of citation follows 3rd CBE Style 
Manual (Council of Biology Editors 1972). Ab- 
breviations follow BioSciences’ Information 
Service (BIOSIS) (1979); abbreviations for 
titles not listed in BIOSIS were constructed 
from National Clearinghouse for Periodical 
Title Word Abbreviations (1971, 1974). The 
annotations are not abstracts of the reports, 
but are intended to summarize information in 
each report relevant to the topic of this bib- 
liography. The descriptors include common 
names of species and keywords. Species names 
refer to those mentioned in the report; common 
names follow Jones et al. (1979) for mammals, 
American Ornithologists! Union (1957) for 
birds, and Collins et al. (1978) for reptiles 
and amphibians. Subspecies are not identified 
except for certain threatened or endangered 
subspecies (for example, the California least 
tern, Sterna albifrons browni). Keywords re- 
fer to specific activities (hiking, climbing, 
etc.), broad habitat types (forests, range- 
land, etc.), agency jurisdiction (e.g., Cana- 
dian National Parks), and selected subjects 
such as recreation management. 
An annotated list of keywords appears in 
Appendix A. In addition to the numbered cita- 
tions, a list of bibliographies on related 
topics is provided in Appendix B. 
Four indexes are provided to assist the 
user in locating specific citations (numbers 







following index entries refer to citation num- 
bers). Keywords are listed in the Keyword In- 
dex. The Author Index lists all senior and 
junior authors. The Species Index lists com- 
mon and scientific names of species, some gen- 
eral terms (e.g., ungulates), and identifies 
species and subspecies considered by the U.S. 
Fish and Wildlife Service (1982) to be threat- 
ened or endangered. The Geographic Index 
lists nations, U.S. and Mexican States, and 
Canadian Provinces and Territories. 
Most of the reports listed can be found in 
any university library. In citing reports 
with more limited distributions, such as con- 
ference proceedings, we attempted to include 
all relevant information to assist the user in 
obtaining the report from the publishing or- 
ganization or through inter-library loan sys- 
tems. Citations of reports from the FWRS 
include the "MIN" number assigned by FWRS; 
copies of these reports can be obtained from 
the Fish and Wildlife Reference Servive, Den- 
ver Public Library Administrative Center, 3840 
York Street, Denver, Colo., 80205. 
As more than 4,000 reports were examined, 
we feel the bibliography represents literature 
published through 1980. We hope the informa- 
tion presented here will improve understanding 
of man's "“nonconsumptive" impact on wildlife 
and that this may lead to some application of 
the reported results.
