As winter approaches, monarch caterpillars fuel up on a Minnesota farm

Kristin Duncanson holds a monarch caterpillar we found on her farm. “Everyone has a monarch story,” she said.

Duncanson Growers is a family farm located in the heart of southern Minnesota. Owners Kristin and Pat Duncanson produce pork and grow corn, soybeans and vegetable peas on the farm, with a commitment to sustainable practices that improve the quality of their land. But it’s not just about environmental sustainability.

“We also need to maintain and increase our productivity to be economically sustainable,” Kristin said.

The Duncanson family has been committed to sustainability not only through their own farming operations, but also through outreach and education efforts. I recently paid a visit to the family’s farm, where just the night before they had hosted 30 college students for dinner, recognizing the importance of communicating their sustainability practices to others.

In addition to their current practices, which include improving data collection to increase fertilizer efficiency, reducing tillage where possible and rotating crops, the Duncansons have also maintained some very high quality habitat for monarch caterpillars and butterflies. Read More »

Why two California farms give me hope for the monarch butterfly

By David Wolfe / Bio / Published: July 18, 2016

The western population of monarch butterflies is in steep decline, according to a recent study released by the Xerces Society, having fallen 74 percent in the past two decades, from roughly 1.2 million in 1997 to fewer than 300,000 butterflies in 2015.

Studies have documented the drop in eastern populations over the past several years, but this is the first time we’ve been able to understand the risks to the western population, which resides west of the Rocky Mountains.

The population is struggling because of development around the forested groves where they spend winters along the California coast and in Mexico, and because of pesticide applications that kill vital milkweed habitat. These threats and the population decline are significant, having the potential to influence a U.S. Fish and Wildlife Service decision in coming years if the situation fails to turn around soon.

I’ve feared for many years that the monarch might reach the point that it will require protections under the Endangered Species Act – a last resort that signals a dire state for the iconic and beloved species. But a recent trip to California gave me great hope that it’s not too late to change the monarch’s trajectory. Read More »

Monarchs still need milkweed, and farmers are growing it

I am watching the rain pour down outside my window as I write this blog. El Niño is once again giving central and north Texas a good drenching, which has brought with it some severe and deadly flood conditions. But the rains are a welcome sight to Texas farmers and ranchers who have become all too used to drought and wildfire conditions. And they aren’t the only ones benefitting from the heavy rains.

All this wet weather has resulted in a spectacular display of spring wildflowers, including vast expanses of milkweed and nectar plants that the iconic North American monarch butterflies need to survive and thrive.

Recent headlines suggest that milkweed loss is just one of several threats to monarch populations, with drought, habitat fragmentation and reduced availability of nectar plants also influencing the species’ decline. In reality, all of these threats are interconnected in a recipe that could spell disaster for the monarch. Read More »
