Species at Risk This 1997 book from the NRC (National Research Council), addresses current preservation challenges posed by the Aga, or Mariana crow (corvus kubaryi) and also reflects the larger issues and challenges of biodiversity conservation in oceanic island ecosystems. The Mariana Crow provides a valuable case study into the nature of "island" ecosystems (which incidentally, are not necessarily surrounded by water) and the special issues their species face.
Here is another study by the NAS on the endangered status of a Pacific Island bird. The Hawaiian Crow, or 'Alala (corvus hawaiiensis), once inhabited nearly all large forested areas of Hawaii. Today it is found in the wild only in a relatively small area of the central Kona coast. The decline of the 'Alala is part of a larger phenomenon of reduction and extinction of forest birds throughout Polynesia that is the direct result of human colonization, and as such, it is a symptom of many underlying ecological problems.
This book explores the threats to the world's sea turtle population and provides sound, scientific conclusions on which dangers are greatest and how they can be addressed most effectively. Five sea turtle species are examined in detail and their feeding habits, preferred nesting areas, and migration routes are discussed. The book examines their status in U.S. waters; and cites examples of conservation measures under way and under consideration.
Endangered Species & Policy Lynx, Lies, and Media Hype - Ted Williams on the Lynxgate Controversy An article by conservation writer Ted Williams on the Lynxgate incident from the May 2002 edition of Audubon magazine. Reprinted here with the author's kind permission. For more of Ted's outstanding, no-nonsense environmental reporting, see the Ted Williams Archive.
A letter by me written in response to a speech given by Jim Buchal to the Kitsap Alliance of Property Owners in Washington state that was published in a Washington-based online sportsmen’s’ forum. Buchal, is a Portland, OR based lawyer for industry and property rights special interests who is known for his confrontational manner and vociferous opposition to science-based salmon recovery efforts. In the referenced speech he claims that genetic diversity and riparian spawning habitat have nothing to do with the health of salmon populations, and viciously attacks the science and scientists behind the research on salmon ecology. In my response I address the pseudoscience and poor reasoning with which he defends his claims and his generally abusive and unprofessional tone.
This article from Ted Williams discusses how wild trout are disappearing from streams and rivers all over the West, and why. In particular, he discusses the case of the West Slope Cutthroat () and the challenges it faces in what little remains of its native habitat in Western states. Despite their interests in preserving trout for future generations, many "sportsmen" have been vehemently, and at times even viciously opposed conservation measures for protecting them. The reasons for such irrational views range from opposition to catch-and-release by fishermen who care only about filling their freezers, to knee-jerk reactions to conservation as "enviro extremism". Needless to say, science has little to do with these views. For more of Ted's outstanding, no-nonsense environmental reporting, see the Ted Williams Archive.
Biodiversity This book from the National Academy of Sciences Press discusses the limitations of the Earth's carrying capacity, the importance of managing natural resources within reasonable limits, and the impacts human activity has had on the biosphere because of our failure to do this. It also addresses the many economic, cultural, and political reasons why modern societies have largely ignored these concerns, particularly in wealthier nations like the United States.
This book from the National Research Council arm of the National Academy of Sciences discusses how measures of economic value frequently exclude the value of the services offered by nature, thereby causing business leaders, economists and policy makers to conclude that environmental measures are too "costly". A proper consideration of nature's impact on human society would lead to very different valuations of environmental policy.
