The U.S. Fish and Wildlife Service has issued a notice of review for plant and animal species that are candidates for listing as endangered or threatened under the Endangered Species Act. The revised list of "candidate species" - part of the Administration's commitment to improve implementation of the Endangered Species Act - is the result of a thorough review of the scientific information available on the species. In its notice of review, published in the February 28 Federal Register, the Service asks for any new information on the status of the candidate species.

The new candidate species list clearly identifies those species with strong scientific evidence indicating they are likely to be in need of listing as endangered or threatened. This will enable the Service, other agencies, and private partners to focus attention and resources on the species that most need help and will, therefore, ultimately reduce the costs and increase the effectiveness of species conservation.

The notice identifies 182 species as "candidates" for listing. "Candidate species" are species for which the Fish and Wildlife Service has enough scientific information to warrant proposing them for listing as endangered or threatened under the Endangered Species Act. Identification of candidate species helps resource managers alleviate threats and thereby possibly remove the need to list species as endangered or threatened. Conservation actions for candidate species are often the most effective and least expensive means for restoring species.

The revised candidate list replaces an old system that listed nearly 4,000 "candidate" species under three separate categories. The old system led many people to the mistaken conclusion that the addition of thousands of species to the endangered list was imminent. Under the revised list, only those species for which there is enough information to support a listing proposal will be called "candidates." These were formerly known as "Category 1 Candidate Species."

With this new announcement, the Service will no longer maintain a list of species formerly known as "Category 2 Candidates". These are species for which the Service does not have enough scientific information to support a listing proposal. The Fish and Wildlife Service is working with federal and state agencies, private conservation groups, and the scientific community to develop data sharing arrangements and continues to assess the status of these species.

In the 22-year history of the Endangered Species Act, the Fish and Wildlife Service has listed 960 U.S. species as endangered or threatened but has determined that 2,400 others do not warrant protection at this time. Over 70% of all species reviewed were found not to warrant listing.

Also in the February 28 Federal Register is a notice explaining the changes in the status of 96 candidate species under the terms of a settlement agreement in a lawsuit filed by the Fund for Animals. This notice explains that scientific review has indicated these 88 plants and 8 animals do not warrant proposal for listing as endangered or threatened. Most of the species were removed for taxonomic reasons, because of a lack of scientific information to support a proposal, or because they are more abundant or less threatened than previously believed. Several of the species were removed from "candidate" status as a result of successful conservation actions that have reduced threats and stabilized their populations. Two species, both Hawaiian plants, were removed because they are believed to be extinct.

The editors of the GreenDisk Paperless Environmental Journal have released the most comprehensive guide to the use of computers for environmental research and activism ever compiled. The guide contains over 1,000 listings of world wide web sites, listservs, online databases, bulletin board services, software, educational programs, CD-roms and datasets. Also included are articles on green computing, listings of service providers, books, conferences, workshops and much more.

Those working in academia, journalism or industry, as well as activists and environmental educators, will find a wealth of information in the guide. The subject criteria are broad - from a listing of congressional e-mail addresses to descriptions of ACCESS EPA, the NASA Space Images CD-Rom and new web sites on the regulation of transgenic arthropods and the oil spill off the Rhode Island coast. The guide is international in scope and ranges from highly technical and specialized listings to more general sources for environmental learning and research.

The guide is available on disk only in IBM or Macintosh formats and includes a user interface for reading and full Boolean (and/or) keyword searching. This allows the user to quickly find the resources related to the topic being researched and saves more than 900 pages of paper that would be required to print the guide. Included with the guide is a full review issue of the GreenDisk focusing on the depletion of the ozone layer.

The cost of the guide is $25. To order, request an order form from: The GreenDisk, P.O. Box 32224, Washington, DC 20007; E- mail:


This summer the Atlantic Center for the Environment will conduct a five-week fellowship program from July 8 - August 11 on land conservation and stewardship for conservation professionals from countries in the Caribbean and Latin America. Six positions will be available. This intensive program will be practical and problem-solving in its approach, introducing participants to conservation issues in the northeastern United States and eastern Canada, and enabling them to begin a dialogue with their North American counterparts. Its broad goals are to provide training and professional development for conservation leaders from the Caribbean and Latin America, promote an exchange of ideas and innovations in the area of landscape conservation and stewardship, and strengthen the capacity of NGOs in both regions to conserve natural areas through stewardship. Through roundtable discussions, site visits and internships, participants will have the opportunity to share ideas with their counterparts, acquire new information and develop their practical skills.

The fellowship program will begin at the Atlantic Center's headquarters in Ipswich, Massachusetts and will involve travel in the northeastern United States. The fellowship program is open to individuals working as leaders, staff or volunteers with a Latin American or Caribbean NGO active in the areas of biodiversity conservation, landscape conservation, sustainable agriculture, sustainable forestry or rural community development.

Interested applicants should request a complete description of program details and application procedure from: Brent Mitchell, Director of Stewardship, QLF/Atlantic Center for the Environment, 55 South Main St., Ipswich, MA 01938; E-mail:; Tel.: (508) 356-0038; Fax: (508) 356-7322. Application deadline: 15 April 1996.

The second volume of Centres of Plant Diversity: A Guide and Strategy for Their Conservation is now available. It covers Central and Northern Asia, the Indian Subcontinent, China and East Asia (Malesia), Australasia and New Zealand, and the Pacific Ocean Islands. Volume 2 contains five regional overviews and 102 data sheets on areas of high floristic diversity in need of conservation. Of all three volumes in the set, these regions contain the highest number of endemic plants with approximately 93,352 species. The sites have been selected partly on the basis of floristic statistics, but especially with reference to the detailed knowledge of numerous botanists familiar with this part of the world. The data sheet for each of the 102 sites is set within a regional context, outlining wider patterns of plant distributions, threats and conservation efforts; additional sites are mentioned in the overviews.

This volume can be purchased for US $67.50 (plus shipping and handling) by writing: IUCN Publications Services Unit, 219c Huntington Road, Cambridge CB3 0DL, England; Tel.: (44) 1223 277894; Fax: (44) 1223 277175 or Island Press, Box 7, Covelo, CA U.S.A.; Tel.: (800) 828-1302 (inside continetal U.S.) or (707) 983- 6432 (outside U.S.); Fax: (707) 983-6414.
