For love of monarchs, Oregon couple grows food to sustain them
NEWBERG, Ore. — Oregon is known for its specialized agricultural production, but Jim and Bonnie Kiser may occupy the state’s narrowest market niche.
Their entire crop this year, seeded in February and March, consisted of 990 milkweed plants. By mid-June, about 800 survived to be given away and planted in yards, parks or gardens.
The plants, Asclepias speciosa, or showy milkweed, are intended as forage for a migratory insect: the monarch butterfly.
The brightly colored monarch has become something of a poster-bug in the debate over pesticide and herbicide use, agriculture’s impact on wildlife habitat, and the role of voluntary conservation efforts in staving off potential regulatory or legal action.
The Kisers are among a cadre of people who have taken it upon themselves to aid monarchs. They’ve been at it since 1998, when they dug up and rescued milkweed plants from a Costco store construction site in Eugene, Ore. They’ve also rescued plants from construction at a Tektronix electronics plant in the Portland area, and at a highway interchange near Rickreall. They have a couple dozen milkweed plants growing in their yard, in addition to the hundreds of seedlings growing in plastic tubes. Last year, they planted 300 milkweed plants at Champoeg State Park.
“This is an amateur operation, but it’s effective,” said Jim Kiser, a semi-retired consulting engineer.
The monarch population has steeply declined; one estimate puts the population loss at 90 percent over the past two decades, although they bounced back this year.
Critics say farming practices, especially in the Midwest, have killed off milkweed, the only plant on which butterfly larvae feed. In March 2016, the Center for Biological Diversity and the Center for Food Safety filed suit against the U.S. Fish and Wildlife Service for failing to protect monarchs under the federal Endangered Species Act.
The two groups blamed planting of genetically modified corn and soy for loss of milkweed in the Midwest. They said farmers spraying Roundup, Monsanto’s trademark herbicide, kill milkweed while leaving “Roundup Ready” corn and soy unscathed.
The groups asked USFWS in 2014 to list monarchs as “threatened” under the ESA, but the agency has not taken action. The March 2016 lawsuit asks a court to set a deadline for a decision by Fish and Wildlife. George Kimbrell, senior attorney for the Center for Food Safety, said settlement negotiations are underway.
In the meantime, USFWS encourages voluntary milkweed plantings, saying that every backyard can become an “oasis” for the butterflies and other pollinators. The agency urges schools, community groups, businesses and state and local governments to plant milkweed on public and private land and in rights of way.
“Monarch declines are symptomatic of environmental problems that also pose risks to food production, the spectacular natural places that help define our national identity, and our own health,” USFWS says on its website.
Monarchs are a compelling story. They migrate south from Canada to Mexico in the fall and head the other way in the spring, going through several generations on the way. The monarch’s primary flyway covers the Midwestern U.S., including the corn belt, but a subset migrates each fall from Canada across the Pacific Northwest to Southern California, reversing direction in the spring.
The notion of helping monarchs by planting milkweed resonates with many people. A group called Monarch Watch advocates a “monarch highway” of milkweed plantings along Interstate 35, which runs from Duluth, Minn., south to Laredo, Texas.
But Kimbrell, the Center for Food Safety attorney, said nothing short of mandatory protection under the Endangered Species Act can help monarchs at this point.
The group applauds voluntary planting efforts, “But it’s not nearly sufficient to save them, unfortunately,” he said by email.
Still, the Kisers and others keep on. Jim Kiser traces his fondness for monarchs to his boyhood in Oklahoma and vivid memories of their twice-annual migrations.
“Collectively,” he said, “we can make quite a difference.”
