KENTUCKY BIODIVERSITY


Kentucky is home to 2,000-3,000 species of plants, more than 200 species of freshwater fish, 105 species of amphibians and reptiles, 340 species of birds, 75 species of mammals, and an unknown number of insects. It also contains a wide variety of ecosystems that support plant and animal life from hardwood forests and grasslands to caves and wetlands.

Kentucky's rich biodiversity contributes greatly to the Commonwealth's cultural and natural heritage and to its economy and quality of life. However, these native species, natural communities and entire ecosystems are not well known and are constantly threatened by a wide range of human activities.

In March, Gov. Brereton C. Jones appointed 32 Kentuckians to the Biodiversity Task Force whose mission is to submit to the governor a written report on the status of biodiversity in Kentucky with recommendations for its maintenance and conservation by October 1995.

In preparing this document, the group will look for factors affecting Kentucky's biodiversity; species, natural areas and parts of the state that need special attention; how government agencies, universities and private organizations can improve coordination of their biodiversity programs; and how to better educate the public on biodiversity issues. The group will recommend a comprehensive detailed strategy for sustaining and protecting local, regional and statewide biodiversity.


PUERTO RICO CONSERVATION FOUNDATION


Since its discovery by Europeans 500 years ago, Puerto Rico has experienced a phenomenal population growth; current population density being 1,000 inhabitants per square mile. Puerto Rico is rich biologically. Of the 3,100 native plant species, 10% are endemic (only found in Puerto Rico) while 5% of the island's 233 species of birds are endemic. Fifty species of reptiles and 23 species of amphibians exhibit 78% endemism. During this century development has been detrimental to the country's natural resources. Much of the island's wildlife is threatend or endangered. Over 90% of the primary forest cover has been lost. A large number of exotic species have been introduced. Less than 5% of the island's wildlands are under legal protection. Although there is an adequate legal framework for protecting the environment, responsible agencies are understaffed, overworked, and interagency coordination is lacking.

The Puerto Rico Conservation Foundation, a non-profit citizen's organization, organized in 1987, is dedicated to the conservation of the island's biodiversity. The Foundation conducts a diverse array of activities, including: public education programs and publication of a newsletter; research programs; land acquisition; synthesis of information; protection of critical habitats; testimony at public hearings; sponsorship of special conservation projects; and fundraising among all sectors of the Puerto Rican Society. Most of the projects are executed jointly with other conservation groups and government agencies. Examples are its efforts to save El Yunque Rain Forest, the only virgin forest left in Puerto Rico and host of the largest segment of biodiversity on the island, and the purchase of Bahia Ballena which was annexed to the Guanica State Forest.

GREAT LAKES PROTECTION FUND


The governors of the Great Lakes states created the Great Lakes Protection Fund in 1989. The Fund is the nation's first multi-state environmental endowment. It seeks to become a global model of political and economic cooperation in the management of a shared natural resource. The Fund was developed after two decades of increasingly cooperative efforts to identify, demonstrate, and promote regional action to enhance the health of the Great Lakes ecosystem. It continues to seek relationships with the Canadian provinces of Ontario and Quebec which also border the Great Lakes.

The Fund has four primary goals: 1) prevent toxic pollution; 2) support effective cleanup approaches in Areas of Concern designated by the International Joint Commission; 3) support natural resource stewardship; and 4) clarify effects of toxic pollution on humans and wildlife. The Fund encourages a range of strategies to meet these goals, including regional coordination, roundtable discussions, policy analysis and evaluation, education for action, promotion of public dialogue through the media, conflict resolution, progam planning and development.

WILDLIFE TRADE AND CITES ISSUES


The World Conservation Monitoring Centre, Cambridge, England, announces "CITES-L", a list for discussion and postings of issues relating to the trade in wildlife and the Convention on International Trade in Endangered Species (CITES). The World Conservation Monitoring Centre (WCMC), where the list will be maintained, has had over 12 years of experience in dealing with wildlife trade issues and maintains a database of all reported trade in CITES-listed species on behalf of the CITES Secretariat. WCMC has regular contact with the CITES Secretariat in Geneva, which will also be a source of up-to-date information. The 9th Conference of the Parties of CITES will be held in November of this year in Fort Lauderdale, Florida, USA and WCMC hopes to post decisions and results of discussions as they take place.

Messages sent to CITES-L are distributed automatically and authors are solely responsible for the content of their posts. WCMC and CITES does not verify the accuracy of submitted messages nor endorse whatsoever is expressed.

If anyone is interested in joining the list, send a one line message to LISTPROC@WCMC.ORG.UK with the command line (in message body): SUBSCRIBE CITES-L , e.g. SUBSCRIBE CITES-L Ronald MacDonald. To sign-off, send a one line message to LISTPROC@WCMC.ORG.UK with the command line (in message body): SIGNOFF CITES-L or UNSUBSCRIBE CITES-L. It should be noted that replying to a message from the list will reply to EVERYONE on the list unless precautions are taken to ensure otherwise.

EARTHWATCH FIELD GRANTS


The Center for Field Research invites field biologists to apply for an Earthwatch field grant. The Center for Field Research encourages and evaluates proposals for support by its international affiliate Earthwatch. Earthwatch is a private, nonprofit organization established in 1971 to fund field research, promote communication between scholars and the public, improve science education, and enhance public understanding of pressing evironmental and social problems.

Through its system of participant funding, Earthwatch supports both basic and applied research. Proposals are welcome for field studies on almost any life science topic, in any country, by advanced scholars of any nationality. The research must have scientific merit and feasibly and constructively involve non-specialist Earthwatch volunteers in the research tasks.

Earthwatch field grants average $20,000. These funds are derived from the contributions of Earthwatch members who enlist for the opportunity to join scientists in the field and assist with data collection and other tasks. On average, each volunteer contributes $600-900 towards the field grant and spends 12-16 days in the field. A typical Earthwatch project employs 4-8 volunteers each on 3-5 sequential teams. To be economically feasible for Earthwatch, the total number of Earthwatch volunteers participating on a project in one year is usually at least 20.

Earthwatch field grants cover the costs of maintaining volunteers and principal researchers in the field. They also help with other project expenses, except principal investigator salaries, capital equipment, overhead, and preparation of results for publications. Applying for grants is a two-stage process. Preliminary proposals are submitted to The Center for Field Research at least 13 months in advance of anticipated field dates. Full proposals are invited upon review of preliminary materials. Proposals are accepted and reviewed year round. For more information, please contact, Dee Robbins, Life Sciences Program Director, The Center for Field Research, 680 Mt. Auburn Street, Watertown, MA 02172; Tel: (617) 926-8200; Fax: (617) 926- 8532; e-mail: drobbins@earthwatch.org.


VIDEO ON WETLANDS


National Wildlife Federation has released a new video entitled "Saving Our Wetlands - Facts and Fictions" which will be a great tool for educating groups on the importance of preserving wetlands for people and wildlife. The video shows the value of wetlands for controlling floods, purifying water and providing wildlife habitat, while cutting through the thicket of half- truths and propaganda spread by anti-environmentalists. The video costs $9.95 plus $3.50 for shipping and handling. To order, send a check or money order to National Wildlife Federation, 1400 16th Street, NW, Washington, DC 20036-9919.


NEW PUBLICATIONS


African Biodiversity: Foundation for the Future, A Frame. work for Integrating Biodiversity, Conservation and Sustainable Development, is the principal product of the first phase of the Biodiversity Analysis for Africa (BAA) Project, implemented by the Biodiversity Support Program and funded by the Africa Bureau of the United States Agency for International Development. The goal of the BAA Project is to help improve efforts in Africa to conserve biological diversity while promoting human prosperity through an analysis of biodiversity conservation approaches currently being used or tested in Africa.

The report identifies numerous recommendations for action to slow the loss of biodiversity in Africa and to make development more sustainable. In the past, conservation strategies for Africa have tended to emphasize the international, scientific values of biological diversity and focus on areas of high species richness and endemism. However, this report proposes new, aggressive strategies that incorporate local and national values.
