HARTFORD, Conn. — Wildlife experts say the "king" of butterflies could go the way of the passenger pigeon unless people step in to plant more of the insect's only food source, milkweed.

The monarch butterfly population has crashed, according to Naomi Edelson, senior director of wildlife partnerships with the National Wildlife Federation. She said it can only be revived with a conservation strategy that improves its habitat by increasing its food supply.

The eastern monarch population has declined 90 percent in recent decades. And Edelson said she believes we'll miss them when they're gone.

"They're at such a low level that if there are some very big, severe storms during the winter, in their wintering grounds in Mexico, we could lose them completely,” Edelson said.

During the caterpillar stage, monarchs live exclusively on milkweed plants. The National Wildlife Federation encourages planting milkweed in natural areas, agricultural lands and backyards to improve habitats.

Edelson pointed to the Mid-America Monarch Conservation Strategy, covering 16 states from Texas to Ohio, as a blueprint for reversing the decline in monarch habit. It includes planting at least 1.3 billion stems of milkweed.

"We have lost all the little strands of milkweed, which usually grow up in the ditches and in between the different crops, because we're so good now at producing food,” she said. “And so there's no more room for the milkweed."

She noted that pollinators like monarch butterflies are responsible for one out of every three bites of food we eat.

Edelson said she worries the decline in monarch butterflies is reminiscent of the fate of the passenger pigeon.

"We had millions of passenger pigeons all across the country, and we lost it completely; there's no more passenger pigeons,” she said. “And the monarch's a similar species that you could never expect we would not have it."

In 2014, a petition was filed to protect the monarch butterfly under the federal Endangered Species Act. A decision on that request is expected in 2019.

The state Department of Natural Resources and Iowa State University are looking for volunteers to help create a new Bumble Bee Atlas.

Bees are an important part of the ecosystem, and scientists are figuring out their habitats to help them thrive.

Iowa is home to at least 14 species of bumble bees that help pollinate native wildflowers and flowering crops in farm fields and backyard gardens.

Iowa State University University Professor of Sustainable Agriculture and plant pathologist Matt O'Neal said the U.S. Fish and Wildlife Service recently listed several bee species as endangered.

"And that includes the Rusty Patch bumble bee," said O'Neal, "20% of what it used to be, and that includes parts of Iowa. There is also evidence that other bumble species are in decline and so, this survey will give us a chance to see where those bees are and how abundant they are."

With that information, O'Neal said scientists can work to protect the bees' habitats and create Iowa's Bumble Bee Atlas.

It's part of a larger project to map the bees and foster bee development nationwide. Sign up online to volunteer.

The national project is part of a collaboration with the Xerces Society for Invertebrate Conservation.

Some 900 people have volunteered for the national atlas project, and counted more than 20,000 bumble bees - which O'Neal said face several major threats.

"Pesticide exposure, parasite and pathogens," said O'Neal, "and then the last 'P,' and probably the most important, is poor forage."

The researchers will work to alleviate those threats by knowing where the bees are.

Volunteers have discovered species thought to be gone from their states, contributed to new field guides, and improved scientists' understanding of bumble bee populations across the country.

A coalition of conservation groups has sued the U.S. Fish and Wildlife Service for refusing to relist wolves under the Endangered Species Act.

Helena-based Alliance for the Wild Rockies is part of the suit. The Alliance sued to successfully overturn the wolf's delisting in 2012 but the move fell victim to congressional funding bill negotiations.

Mike Garrity, executive director of the alliance, said the wolves clearly qualify to be protected under the Act and hunting is driving down their numbers, which could cause problems for the animals.

"As their numbers decline, they are at greater risk for inbreeding," Garrity pointed out. "Once inbreeding sets in, the population is sunk."

Livestock and cattle owners argued wolves are a threat to their flocks and herds and want their numbers reduced. The suit was filed in federal District Court in Missoula.

Beyond keeping a robust population of wolves on Montana's lands and helping their species thrive, Garrity noted wolves can also help reduce the population of diseased animals.

"We're starting to have disease in deer, such as Chronic Wasting Disease," Garrity explained. "Predators like wolves are really good at focusing on the sick animals, so that's an excellent way to control Chronic Wasting Disease."

Garrity added wolf management policies in Montana, Idaho and Wyoming, all of which allow aggressive hunting of the animals, fail to protect wolves and all native species for future generations, the primary mandate of the Endangered Species Act.

A lawsuit over a federal agency's decision not to boost wolf protections in New Mexico and other western states has been filed, days after video surfaced showing the torture of a captured wolf.

According to accounts, a Wyoming man ran the wolf down with a snowmobile in late February, disabling it. He then took it to a local bar and posed for photos before shooting it.

Erik Molvar, executive director of the Western Watersheds Project, said federal protections under the Endangered Species Act are essential because there are still those who don't respect wildlife.

"That's why wolves were driven extinct in the first place, is because these types of people were the ones who controlled the public policy discussion throughout much of the 20th century when wolves were driven extinct," he said.

In early February, the U.S. Fish and Wildlife Service declined to restore protections for gray wolves in western states. The agency said it concluded the animals weren't in danger of extinction under the Endangered Species Act.

The lawsuit was filed by the Western Environmental Law Center on behalf of Western Watersheds and a coalition of nine other conservation groups.

Molvar believes the federal agency's decision not to re-designate western wolves as "endangered" was profoundly misguided. He said some states such as New Mexico and Colorado have adopted extra penalties for killing wolves, but the Endangered Species Act lets hunters in other states off the hook if they claim it was a case of mistaken identity.

"There were special loopholes for Wyoming, Idaho and Montana - and also parts of Oregon, Washington and Utah - so it does beg the question of how often this is happening quietly and under the radar," he explained.

In Wyoming, wolves and coyotes, which are considered predators, aren't eligible for protections under the state's animal cruelty statute. To date, the only penalty inflicted on the person shown on social media tormenting the wolf was a $250 fine by the Wyoming Game and Fish Department.
