Thank you so much for links to article Frank; it was a surprise to me that so many species in the USA still need protection

. Think amphibians need special help in the face of human encroachment and climate changes affecting the whole planet.
After reading your article, followed some of the available links and came to the
NatureServe website. In there found a nice comprehensive article in PDF discussing the present status of new world amphibians:
Disappearing Jewels by Young Et Al, 2004. It's a bit dated; but provides a complete background of frog conservation status. Also at NaturServe website, are links to other documents, including Global Amphibian Assessment Fact Sheets for USA and other locations. Thanks again and good luck
