Once a pesky plant for farmers, this weed presents a new opportunity

A recent article called milkweed a “yield-robbing weed” for farmers.

Milkweed has a reputation for encroaching on cropland where it can compete with crops for soil and light. The plant can also create a nuisance on ranchlands, as cattle can be poisoned when poor foraging conditions lead hungry cows to milkweed-concentrated areas as a last resort.

This is why milkweed is difficult to find on most farms and ranches today. Along with climate change, it’s also a key reason why the beloved monarch butterfly population has declined by more than 90 percent in the last two decades.

The importance of milkweed

Milkweed is essential for monarchs, since butterflies need the plant to lay their eggs, and caterpillars exclusively feed on the milky sap-filled plant. It’s what makes monarchs poisonous to predators.

Increased herbicide application across the agricultural landscape, as well as mowing in roadside ditches and marginal areas, is eradicating milkweed from rural areas in the Corn Belt and other key regions of the monarch’s migration route.

In order to turn things around for the monarch, we need to change the incentive for landowners from spraying and mowing to protecting and restoring this vital habitat. Read More »

How the Midwest can save the monarch

Monarch lands on a milkweed in the Midwest

Monarch populations have declined by 90 percent in the past two decades due, in large part, to the loss of milkweed across the Midwest.

Once again, summer has brought the highly anticipated sightings of monarch butterflies across the country. An online tracker from Journey North shows the beloved orange and black butterflies fanning across the Northeast and Upper Midwest, where the eastern population is completing its northern migration. I spotted a monarch in Missouri just last week.

It’s a wonderful sight and an inspiring reminder of the monarch’s magical migration. But the opportunity to witness this natural miracle is dwindling. Over the last two decades, the monarch population has declined by 90 percent, bringing the butterfly dangerously close to extinction.

There are many factors contributing to this devastating loss, from climate change to deforestation. But a major contributor is the loss of milkweed habitat across the U.S., particularly in the Midwest where native prairies have largely been converted for agricultural use. Monarchs need milkweed to lay their eggs – eggs that turn into caterpillars that feed exclusively on the milky plants. So how do we restore this vital milkweed habitat where monarchs need it the most? Read More »

From testing to launch: A new program for monarchs takes flight

Audrey applies the Habitat Quantification Tool to a potential restoration site, counting the number of milkweed and wildflower stems within a transect.

This spring, my colleagues and I visited three ranches in Texas to begin piloting the Monarch Butterfly Habitat Exchange, an emerging program that will help agricultural landowners contribute to monarch recovery.

Elm Ridge Ranch, Wagley Ranch and Shield Ranch will be among the first restoration projects conducted this year to improve ranchlands and create valuable monarch habitat. We will continue to work closely with these landowners to hone the program and ensure it works for monarchs, pollinators and people alike.

Already, we’ve had the opportunity to gain valuable insights, including how to improve habitat quantification and how to inspire enrollment.

How food companies can turn the pollinator emergency into a big opportunity

Bees, beetles and butterflies are in big trouble.

Pollinators all over the world are experiencing dramatic declines in populations, with about 40 percent of all invertebrate pollinator species facing a very real threat of extinction. Just last October, several species of bees were added to the U.S. Endangered Species List for the first time. Monarch butterfly populations also face the potential threat of a future listing, with populations down by more than 90 percent in recent decades.

These stats are concerning because pollinator health is a strong indicator of an ecosystem’s overall health. Pollinator decline directly correlates with habitat loss, decreased plant diversity, and increased disease in the ecosystem.

This problem cannot be solved by any one sector. Restoration of pollinator habitats will require significant investment and collaboration between both public and private sectors – especially businesses with bottom lines directly tied to pollinator success. Read More »
