TEXAS ENDANGERED SPECIES PROGRAM


Recent reorganization within the Texas Parks and Wildlife Department division that focuses on conservation of endangered resources has resulted in a single program. The Endangered Resources Branch (ERB) of the Texas Parks and Wildlife Department has merged the former National Heritage Program with the Endangered Species Program. The Biological Conservation Database (BCD) continues to provide the core source of information used by the ERB. With more than 3,500 annual users, the BCD provides an essential service to Texas landowners, other conservationists, consultants, and government agencies.

Texas is unique among western states in its size and in the high percentage of privately owned land within its borders. Only about three percent of the land area in Texas is publicly owned. These fundamental factors must be considered in the development of natural resource conservation strategies in the state. This also means that a great percentage of Texas's biological diversity occurs on privately owned land. A 1995 law was passed requiring written permission from landowners before agency personnel or others could collect natural resource data on privately owned property. There had been a several-year trend during which it had become increasingly difficult to collect such data on private land. The need for written permission also applies to the Department's ability to store the data in heritage (or other) database and to report and publicize data in a way that would identify property. This law is thought by some to be a positive development in that many landowners who are not well- informed about their choices will actually make the choice to allow data collection on their property.

The Texas Parks and Wildlife Department, including the ERB, does not have funds for land acquisition for the purpose of biodiversity conservation at this time. Instead, a principal goal of the ERB is to supply quality, practical information on the state's resources to as many users as possible. This information will complement the stewardship interest that already exists with most of the landowners, and which, in a real sense, is the reason for the persistence of much of Texas's biological diversity.

The Endangered Resources Branch is working on other strategies to encourage conservation among private landowners. One is the development of a "safe harbor" habitat conservation plan for endangered woodpeckers in East Texas. Branch staff also are working with landowners in South Texas to develop a cooperative agreement to voluntarily conserve an endangered plant. Another is an effort, assisted by state universities, to develop an importance index for the natural communities of Texas (which are tracked in the BCD) based on the occurrence of endangered/threatened species within the communities and the respective rarity of the communities themselves. This, in turn, provides a measure of "conservation value." When communities with high conservation value are identified, the Branch will alert public leaders and landowners, stressing that they have done a good job in conserving local endangered resources and that Texas Parks and Wildlife Department staff are available if assistance is needed. Beginning this year, conservation easements will be formally encouraged and an incentive program may be established.

In all, the future looks bright for endangered resource conservation in Texas. For a state with a long history of ranching and some past land abuses, this is good news. And in the current social climate that emphasizes landowners' rights, it is encouraging to find that landowners are interested in cooperating in the effort to conserve biological diversity.

INFORMATION HIGHWAY HI-LITES


On June 8, 1996, the American Museum of Natural History launched its site on the World Wide Web (found at http://www.amnh.org), as part of its ongoing effort to expand its educational reach and bring its vast resources to the widest public possible. The Museum's Web site contains a wide range of material, from general information on the Museum and its programs to detailed information on exhibits, scientific research, and educational programs. Of special interest to educators, the "Education" section provides an overview of educational offerings at the Museum. This section will soon include a science "I.Q" quiz ("Sci-Q"), a teachers' guide to "Expedition: Treasures", and a range of other resources and activities for teachers, other adults, and children.

The Museum's Web site makes use of "Java", a programming language that enables the site to function in a manner much like a CD-ROM, allowing users to interact with "virtual exhibits" complete with movement, sound, video, images, and text.

The National Biological Service has identified several World Wide Web sites, available through the National Biological Information Infrastructure, that provide data and/or information relating to U.S. national parks. The listing of these sites can be accessed on the World Wide Web at http://www.nbs.gov/pr/newsrelease/nps.html.


NEW PUBLICATIONS


The Sierra Club Green Guide: Everybody's Desk Reference to Environmental Information, by Andrew J. Feldman, is an essential reference and networking tool providing complete access to the vast array of organizations and services that offer information on environmental issues, including toxic substances, solid and hazardous waste, endangered species, environmental justice, sustainable communities, air and water quality, and alternative energy sources. Encyclopedic in its scope, the Green Guide, offers the reader in-depth evaluations of and introductions to the 1,200 most useful informational sources, with 250 online sources, more than 100 on the Internet alone. The Sierra Club Green Guide sets a new standard for environmental reference works by introducing an extensive cross- referencing system which enables readers to find resources quickly and efficiently.

In addition to serving as an essential professional desk reference, the guide is a primer for ecologically friendly living, covering the full range of "green living" issues, including eco- travel, funding resources, employment opportunities, environmental education and socially responsible investing.

It is available at bookstores, or by direct mail ($25.00, plus $6.00 postage and handling) from: Sierra Club Store Orders, 730 Polk St., San Francisco, CA 94109, or call 1-800-935-1056.

Change is one constant and dynamic force that is continuously influencing faunal diversity in forests around the world. The design of strategies to conserve forest species and habitats is needed in many parts of the world today. A new publication, Conservation of Faunal Diversity in Forested Landscapes, edited by R.M DeGraaf and R.I. Miller, serves to coalesce the knowledge of conservation scientists in different parts of the world in regard to the current influence of environmental change on forest fauna.

The book highlights the status of key vertebrates inhabiting the world's forests and the past and current effects that environmental change exerts upon these populations. The evidence of changes in forested ecosystems are proposed. Several chapters concern the current methods used in the verification of the impacts of change and disturbance on forest wildlife. These methods will help to identify priority forested areas for conservation. Finally, the integration of landscape ecology and its application to forest wildlife conservation is demonstrated.

The Smithsonian Institution's Biological Diversity of the Guianas Program (BDG) is looking for an interim manager to run the Centre for the Study of Biological Diversity (CSBD) on the campus of, and in cooperation with, the University of Guyana (UG) in Georgetown. The BDG is a field-oriented endeavor that has been in operation since 1983. Its goal is to study, document, and preserve the biological diversity of the Guianas. Originally confined to botany, it has since expanded to include faunal and general biodiversity studies as well.

The CSBD opened in June 1992 and houses a herbarium, a zoological collection, small library, GIS center, and staff offices. The interim manager is the focal point for all biological diversity activities for the BDG Program. Because of the nature of the program, a biologist with a good knowledge of field research and taxonomy and who would be willing to work under what are, at the present time, less than optimal conditions, is preferred.
