BIRD PROTECTION IN THE CZECH AND SLOVAK REPUBLICS
Despite over forty years of environmental damage due to central planning, the Czech and Slovak Republics host a remarkable variety of birdlife. Several private groups have diligently been working to preserve many bird species and their habitats. While the past three years of democratic governance have seen an increase in bird protection activities, and the passage of a general environmental law and a republic-level Nature Protection Act, environmental agencies in both republics have yet to demonstrate their commitment to enforcing these new acts. Non-governmental organizations therefore will continue to play a critical role in future bird protection efforts.
Following are several of the key organizations and their activities. The Czech Ornithological Society is the oldest and largest NGO for bird research and study in the Czech Republic. The Slovak Ornithological Society is the sister organization in Slovakia. Both organizations are oriented towards research into such issues as population dynamics, migration patterns, and ecology. They also focus on specific taxa or species and efforts to educate the public about birds.
The Moravian Ornithological Association serves both repub. lics and is involved in bird research and preservation. The "Green Hotline," which provides emergency or long-term care for injured animals, and the Aves Foundation, which supports projects to educate the public, conduct research, and protect endangered species and crucial habitat, are both creations of the Moravian Ornithological Association.
Project Falco (initiated by the Club for Protection of Owls and Birds of Prey) guards the nests of the Saker Falcon (Falco cherrug) in Slovakia from bird traders who steal and sell the falcon's eggs and chicks. The project, initiated in 1990 with 100 volunteers, grew to more than 300 volunteers by 1992 and has received support from the World Wildlife Fund International.
The White Stork Specialist Group, established in 1981, is continuing a population study of the White Stork (Ciconia ciconia) that began in 1934. A 50% decrease in the population in Slovakia over the last fifty years is thought to be linked to a decrease in the reproduction rate, and the destruction of the storks and their nests by electrocution or destruction by elec. tric companies when they try to nest on electric utility poles.
The above are only a few examples of the wide range of activities currently carried out within the Czech and Slovak Republics. Other projects include a project to reestablish White-tailed Eagles to southern Bohemia, Black Stork and Red- spotted Bluethroat research, and many other research and protection projects. Despite initial successes, many projects suffer from a lack of adequate financial resources and full-time professional staffs.
SEA TURTLE ON-LINE BIBLIOGRAPHY AND E-MAIL INFORMATION NETWORK
The Archie Carr Center for Sea Turtle Research (ACCSTR) at the University of Florida has developed the "Sea Turtle Bibliographic Database" which can be accessed worldwide free of charge via Internet. This on-line bibliography includes all aspects of sea turtle biology, conservation and management. Citations are from recognized bibliographic sources, as well as the "gray literature." The database is continually being edited and updated. To help maintain a comprehensive library, reprints of any sea turtle publications will be appreciated.
The ACCSTR has also established CTURTLE--an electronic mail conference and bulletin board to improve communication among individuals around the world who are interested in sea turtle biology and conservation. CTURTLE is a LISTSERV managed e-mail list on BITNET. Participation in CTURTLE is free of charge and the possibilities for and benefits of information exchange are enormous. CTURTLE provides the opportuinty to respond to conservation issues when time is a critical factor.
For further information regarding the Sea Turtle Bibliographic Database and CTURTLE write or call: Archie Carr Center for Sea Turtle Research, Bartram Hall, University of Florida, Gainesville, FL 32611. Fax: (904) 392-9166; E-mail (Internet): ACCSTR@zoo.ufl.edu.
AWARD ANNOUNCEMENT

Sperling, Ph.D., of the National Germplasm Resources Laboratory at the U.S. Department of Agriculture was named recipient of the Richard Evans Schultes Award for his outstanding contributions to the field of ethnobotany on June 14, 1993. The award honors Harvard Professor Emeritus Richard Evans Schultes, co-author ofThe Healing Forest: Medicinal and Toxic Plants of the Northwest Amazonia, and widely recognized as the Father of Ethnobotany. "Calvin Sperling," said Schultes, "is one of the foremost ethnobotanists today due to his consistent excellence in field research and to his extensive work to conserve biological diversity and to improve crop plants worldwide." Sperling was recognized for his comprehensive work as a field ethnobotanist in the preservation of genetic resources and the ethnobotany of economic plants.
NEW PUBLICATIONS
The Papua New Guinea Conservation Needs Assessment
Report, examines and explains the Conservation Needs
Assessment (CNA) for Papua New Guinea requested by the government
of Papua New Guinea and funded by the U.S. Agency for
International Development (USAID). The CNA was implemented by the
Biodiversity Support Program, a USAID-funded consortium of the
World Wildlife Fund, World Resources Institute, and The Nature
Conservancy, in collaboration with local and international NGOs,
museums, and academic institutions. The assessment compiled an
extensive body of the available scientific literature on the
biodiversity of Papua New Guinea and assessed the present state
of knowledge, conditions, trends, and environmental threats. A
CNA workshop was then conducted in Papua New Guinea to discuss
the findings, consider a range of recommendations for
conservation initiatives, and develop a process for information
sharing and concensus decision making. Volume 1 contains reports
on conservation issues and opportunities in Papua New Guinea and
includes assessments of information management needs. It also
includes a summary of material presented and discussed at the CNA
workshop and maps of biodiversity in Papua New Guinea, the points
of agreement among participants, issues remaining to be resolved,
and a detailed set of recommendations for action. Volume 2
presents the technical reports of the natural scientists on the
biological diversity of Papua New Guinea, and includes extensive
documentation of the available scientific literature on Papua New
Guinea's biota. To receive more information about the full two
volume report, contact: Janis B. Alcorn, Program Manager,
Biodiversity Support Program, c/o World Wildlife Fund, 1250 24th
Street, NW, Washington D.C. 20037. Tel: (202) 293-4800; Fax:

The Fisheries Conservation Program of the Center for Marine Conservation has just put out a booklet entitled Fish for the Future: A Citizen's Guide to Federal Marine Fisheries Management. The guide is aimed at citizens who are concerned about maintaining the integrity of oceans and coastal communities; it encourages people to take an active role in the fishery management process. The Citizen's Guide provides people with the tools to advocate conservation through fishery management. This document is available through the Center for Marine Conservation for $7.95 per copy. For further information, or to request a copy, contact: David Allison, Director of the Fisheries Conservation Program, Center for Marine Conservation, 1725 DeSales St., NW, Washington, D.C. 20036. Tel: (202) 429- 5609.
CALL FOR PROPOSALS
The Center for Field Research (CFR) invites proposals for conservation biology research to be conducted in 1994. CFR recommends projects to the funding organization Earthwatch. Earthwatch recruits nonspecialist, English-speaking volunteers to assist scientists with data collection. Field grants average $15,000 when 20 Earthwatch volunteers are utilized over the course of a field research session. Proposals should be received one year in advance of anticipated field dates. For more information contact Dee Robbins, Program Director, The Center for Field Research, 680 Mt. Auburn Street, Watertown, MA 02171. Tel: (617) 926-8200; Fax: (617) 926-8532.
EDUCATIONAL MATERIALS
A timely 35-minute video, Promising Approaches to
Tropical Forest Management in Latin America, shows how natural
forest management can provide a viable alternative to
deforestation in the humid tropics. Through interviews with
experts and footage of ongoing natural forest management projects
in Mexico, Costa Rica, and Ecuador, the video describes how
tropical forests can be sustainably managed for timber and other
products. Such use can maintain a high level of biological
diversity while providing a competitive economic return to those
who would otherwise convert the forest to cropland or pasture.
The video is a useful resource for organizations concerned with
promoting forest conservation, and an ideal educational tool that
introduces the many ways in which standing forests are valuable.
The video, available in English and Spanish, is being distributed
by the Tropical Forest Management Trust, at $18 each. Checks
should be made to Tropical Forest Management Trust, Inc., 6124 SW
30th Ave., Gainesville, FL 32608. Tel. (904) 331-2007; Fax (904)
331-3284.
Video tapes on the colony of stumptail macaques (Macaca arctoides) on Tanaxpillo Island in Lake Catemaco, Veracruz State, Mexico are available. The tapes document some of the logistics and methods used in a study on the social ecology of stumptail macaques and aspects of their behavior and ecology. Copies of the tape may be purchased for $18. Contact Larry Guss, Guss Adventure Travel Productions, 5319 Strathmore Avenue, Kensington, MD 20895. Tel: (301) 933-3337.
FUTURE MEETINGS
August 24-26. "Creating A Forestry for the 21 Century: A Landmark Symposium," sponsored by the Olympic Natural Resources Center at the University of Washington, will be held in Portland, Oregon. This landmark forestry symposium will bring together some of the best creative thinkers in the field to explore what kind of forestry we might create for this and the next century, based on what we have learned over the last few decades. The symposium will examine the state of our knowledge with respect to forest systems and explore the implications of that knowledge of forest management, planning, and policy. The event will include plenary sessions, displays, demonstrations, discussion sessions, and field trips and will culminate in the production of a book. Registration: $330.
