U.S. Agency Proposes Legislation to Help Stem Spread of Chytrid Fungus

Monday, September 27th, 2010

In an effort to stem the spread of the deadly chytrid fungus that is wiping out amphibian populations, the U.S. Fish and Wildlife Service (FWS) is considering banning the importation of amphibians and their eggs without a permit certifying the animals are disease-free. The chytrid fungus has caused the extinction of at least 200 amphibian species and continues to be one of the greatest threats to amphibians.

In a statement, Rowan Gould, Acting Director of the U.S. Fish and Wildlife Service, said,

The worldwide decline of amphibians is of great concern to us. Chytrid is attributed as a major cause of this amphibian mortality. We understand that halting the spread of the fungus or eradicating it will take more than just regulating importation and transportation of infected amphibians, but it is a major step in the right direction.

According the the FWS website, under the Lacey Act, the Department of the Interior is authorized to regulate the importation and interstate transport of wildlife species determined to be injurious to the welfare and survival of native wildlife. Current regulations prohibit the release into the wild of all species of live amphibians or their eggs, except as authorized. But, of course, this law isn’t easily enforced. Many pet frogs are let “free” in local ponds, potentially infecting native species.

A listing under the Lacey Act would not affect a person or institution that currently owns an amphibian and does not transport it to another state or U.S. territory.

At FROGS ARE GREEN, we applaud this proposed legislation and feel it would be a huge step toward controlling the spread of the chytrid fungus that threatens the survival of so many amphibian species, including native species listed under the Endangered Species Act.

The FWS is seeking input from the public. You can leave a comment until December 16, 2010. Please take a few minutes to comment and to show your support for a measure that will genuinely help amphibians.

A Field of Nightmares Updated: Atrazine, Corn, and Frogs

Wednesday, August 11th, 2010

As Susan and I are hosting family and friends, we are reposting a couple of posts this week from the past year. We’ve updated this post with new material below. This post originally ran in January 2010.

I’ve always had a sentimental attachment to cornfields—from the magical cornfield in Field of Dreams to the real cornfield across the road from a house I lived in during college years. My mother was born and raised in Iowa and I’m descended from Iowan farmers.

But chemicals, in particular Atrazine, used as herbicides on cornfields might be poisoning frogs (and people), and turning fields of dreams into fields of nightmares. These herbicides run off cornfields into streams and rivers, and leak through the water-treatment process, contaminating groundwater and drinking-water supplies.

Last summer we blogged about the problems of Atrazine. Research by University of California, Berkeley professor Dr. Tyrone Hayes, for example, has shown the effects this chemical—an endrocrine disruptor—has on frogs. It can cause birth defects and reproductive problems, including such bizarre deformities as male frogs with eggs in their testes. As reported in the Washington Post, new research at the University of Ottawa found that when exposed to Atrazine fewer tadpoles reached froglet stage. Atrazine appears to affect estrogen in humans as well and has been connected with ferility problems, cancer, and birth defects.

Warning in a Cornfield

The EPA, under the Obama administration, has launched a review of the chemical that will continue until fall 2010. It will look closely at Atrazine and other endrocrine disruptors, which might result in tighter restrictions on their use. While this sounds hopeful, Atrazine’s primary manufacturer, Syngenta, has strong ties and influence within the EPA. (Atrazine is banned in Europe, where perhaps industry and government aren’t as closely intertwined as they are in the U.S.).

For more information, please see this PDF, a report by the Land Stewardship Project and the Pesticide Action Network North America titled The Syngenta Corporation: The Cost to the Land, People, and Democracy.

Update 8/10: Save the Frogs is sponsoring the International Day of Pesticide Action, in Washington, DC, on October 24, 2010, a march through the streets of DC from the steps of the Capitol to the Environmental Protection Agency demanding a federal ban on Atrazine, the 21st Century’s DDT. Please visit the Save the Frogs site for more information and to sign a petition to get Atrazine banned. (Note: Susan designed the logo below)
