WASHINGTON — A coalition of environmental and food-safety groups is asking the Fish and Wildlife Service to grant endangered species protection to the monarch butterfly, whose U.S. population, the groups say, last year fell to 90 percent below its 20-year average.

In a petition asking for the designation, which would allow the federal government to more aggressively protect the butterfly and its habitat, the petitioners blamed Monsanto Co.’s Roundup herbicide and Roundup Ready crops for much of the decline.

“The vast majority of genetically engineered crops are made to be resistant to Monsanto’s Roundup herbicide, a uniquely potent killer of milkweed, the monarch caterpillar’s only food,” the Center for Biological Diversity, the Center for Food Safety and the Xerces Society said in a joint statement, also signed by monarch scientist Lincoln Brower of Virginia’s Sweet Briar College.

The statement said that the “butterfly’s dramatic decline is being driven by the widespread planting of genetically engineered crops in the Midwest where most monarchs are born.

Butterfly migration

“The dramatic surge in Roundup use with Roundup Ready crops has virtually wiped out milkweed plants in Midwestern corn and soybean fields,” the statement said.

In an emailed response, Monsanto spokeswoman Charla Lord said:

“Scientists think a number of inter-related factors are contributing to the decline and year-to-year variation of monarch butterfly populations. While weather events (snow fall and frost) at mountaintop overwintering sites and logging in Mexico continue to be factors, experts are also focusing on agricultural practices and land use changes that have reduced milkweeds along the migration path in central regions of North America.”

She said Monsanto would help “restore habitat that supports the monarch migration.”

The environmental and food-safety groups say the butterfly’s population has fallen from a high of 1 billion in the mid-1990s to about 35 million last year, and that that number is only about a tenth of the 20-year average. The monarch is also threatened by climate change, drought and heat waves, urban sprawl and logging on their wintering grounds in Mexico, the petitioners said.

Tierra Curry, a senior scientist at the Center for Biological Diversity, said good weather this year may boost numbers when the group Monarch Watch does its winter survey, but “we’re at risk of losing a symbolic backyard beauty that has been part of the childhood of every generation.”

Gavin Shire, a spokesman for the Fish and Wildlife Service, said his agency was required by federal regulations to respond to the petition “to the extent practicable” within 90 days. The agency could decide to extend the review up by nine months more before deciding on the request. The butterfly currently has no special protection designation from the FWS.

The Missouri Department of Conservation has been monitoring the monarch’s decline. The organization’s Tim Smith predicted on the agency’s website in April that “the sight of the beautiful orange and black monarch butterfly in Missouri is likely to be less common this year.”

Smith cited a report that monarchs occupied only 1.65 acres of Mexican forest last winter, the third straight year of steep declines in its over-wintering areas. The largest area recorded was 45 acres in 1996, Smith wrote.

“A number of factors have contributed to the decline of the monarch population in recent years,” Smith wrote on the MDC website. “Unusually hot weather in the spring of 2012, unusually cold weather last spring, and the loss of habitat throughout the Great Plains have combined to create hardships for the insects.” He also cited “weed-free farming techniques” as a contributing cause for the decline.

The Center for Biological Security is a nonprofit conservation organization focused on endangered species and wild-place protection. The Center for Food Safety, also a nonprofit, advocates sustainable alternatives to food production. The nonprofit Xerces Society advocates for the conservation of invertebrates and their habitat.
