The Wildlife Society believes that increased awareness and appreciation of wildlife values is an important objective. Society publications are one means of doing this.
Wildlife Monographs was begun in 1957 to provide for longer papers than those normally accepted for The Journal of Wildlife Management. There is no set schedule for publication. Individual issues of Wildlife Monographs will be published as suitable manuscripts are accepted and processed and when financing has been arranged.
Each Monograph is sponsored financially by organizations or institutions interested in publication of the information contained therein. Usually, the sponsor is the organization that conducted the original research, but others interested in disseminating the information may assist in defraying Monograph costs. The sponsors pay for printing and distribution of each Monograph, and The Wildlife Society provides skilled editors to assist Monograph authors and assures wide distribution through its worldwide mailing list to a select group of knowledgeable wildlife scientists, libraries, and others, and to members and subscribers who receive The Journal of Wildlife Management.
There is a perpetual need for additional funds to sponsor publication of worthwhile manuscripts in Wildlife Monographs. Any contribution will be accepted with gratitude by The Wildlife Society. Memorial funds collected to honor and perpetuate the names of deceased members of the profession probably could be put to no better use.
