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.

We need to get creative to protect wildlife in the face of climate risk

The Swainson's hawk will need to be protected from the effects of climate change

A pilot project for Swainson’s hawk is creating high-quality nesting habitat on a 4,000-acre farm in San Joaquin County.

Landowners and environmentalists both grapple with the same question: In the midst of uncertainty, what is the most effective way to reconcile short-term and long-term needs for wildlife habitat?

For example, it can be risky to invest in permanent conservation on a property vulnerable to climate change, but failing to protect existing habitat in the face of uncertainty is an existential threat to species like the Swainson’s hawk.

Fortunately, new habitat accounting tools are emerging that bring more certainty to conservation planning, which helps landowners make effective management decisions for their property, helps biologists design effective restoration plans and ultimately helps wildlife thrive. Read More »

How healthy riparian forests benefit California ranchers

John Anderson overlooking his riparian forest and restoration area on Yanci Ranch.

California landowners have a number of important reasons to value riparian forests. They offer shade to cattle, provide critical erosion and flood control, sequester carbon and support abundant wildlife.

Yet many landowners, especially those already stretched to manage their farms and ranches, often overlook these benefits in their day-to-day work.

Unfortunately, California’s riparian forests are dwindling, covering only 5 percent of their historic range.  That’s why Environmental Defense Fund (EDF) is working with leading researchers in the state to measure the wildlife and carbon benefits of riparian restoration, with the objective of bringing new funding sources to stewards of private lands.

Meet John Anderson

One landowner who is working actively to create riparian forests on his ranch is John Anderson, owner of Yanci Ranch in Yolo County. An experienced steward of his land, John has gone the extra mile restore the remnant riparian forest on his property. Read More »

The year the private sector stepped up for land, water and wildlife

The private sector stepped up for land, water and wildlifeBy this time next year, I believe we’ll reflect back on 2017 as the year that the private sector stepped up to protect our land, water and wildlife for future generations.

I believe this because major retailers, food companies, agricultural businesses and farmers laid the groundwork in 2016, making sizeable commitments to reduce greenhouse gas emissions (GHGs), improve water quality and conserve habitat for imperiled wildlife.

President-elect Trump has made political theater by threatening to kill the regulations that protect our nation’s air and water. But in the real world, the private sector is going the other direction.

Forward-thinking businesses are rolling up their sleeves and finding ways to make those regulations work better by accelerating the uptake of practices that are good for the planet and the bottom line.

These are three areas to watch in 2017.

As monarch butterflies have returned to Texas on their fall migration south, so have my colleagues and I to Shield Ranch for another round of field testing for the Monarch Butterfly Habitat Exchange, a new conservation program we expect to launch in key states in 2017.

Texas offers a lot of potential habitat for monarchs, being a critical layover on the species’ annual migrations north and south, and having a number of landowners willing and eager to find a solution for the iconic butterfly’s decline.

During our visit to Shield Ranch, we saw dozens of monarchs and other butterflies, as an unusually high amount of rain in August sparked a profusion of fall wildflowers in central Texas. With targeted conservation funding through the Monarch Butterfly Habitat Exchange, we can make rapid progress on the ground. Read More »

California’s new law means more bang for every buck invested in wildlife

The Swainson's hawk was listed as a threatened species in California in 1983 due to loss of habitat and decreased numbers across the state.

The Swainson’s hawk is one of the at-risk species that AB 2087 benefits.

Prudent investors know to keep a few key things in mind. They anticipate the timing of spending priorities, like retirement, and evaluate investment risk accordingly. They might spread resources across funds to meet different objectives. And of course, they look to maximize their return on investment.

Why shouldn’t these same principles apply to investments in our natural resources?

Thanks to a new bill signed into law by Governor Jerry Brown, these principles will now apply to regional conservation investment strategies for wildlife and other resource management activities in California.

AB 2087: A new approach to conservation planning and mitigation

Assembly Bill (AB) 2087 (Levine), will establish voluntary, non-regulatory strategies to help conservationists, local agencies and the state apply core investment principles when planning conservation or mitigation projects.

This legislation comes at a critical time. Expanding development in California has supported a growth in food production, flood protection, transportation and housing, but it has also resulted in various impacts on the environment. The loss and fragmentation of wildlife habitat, in particular, has created a need for the state to restore and maintain at least 600,000 acres for multiple at-risk species in the coming decades.

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

Kristin Duncanson shows me monarch caterpillar we found on her farm. “Everyone has a monarch story," she said.

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 »

How can we better target public funds for wildlife conservation? Look to Elliott Ranch

The Swainson's hawk was listed as a threatened species in California in 1983 due to loss of habitat and decreased numbers across the state.

The Swainson’s hawk was listed as a threatened species in California in 1983 due to loss of habitat and decreased numbers across the state.

This week, the Delta Conservancy, a California state agency, awarded Environmental Defense Fund (EDF) a grant of $380,000 to implement a habitat enhancement project for the state-listed Swainson’s hawk on Elliott Ranch in West Sacramento, near the Sacramento-San Joaquin Delta. The grant is part of California’s public water bond funding being managed by the Delta Conservancy to restore wildlife habitat in the Central Valley.

The Elliott Ranch project will enhance Swainson’s hawk habitat on 300 acres. Specifically, the project will expand the hawks’ hunting grounds by restoring habitat for their prey and converting existing crops to bird-friendly pasture.

Central to the project will be the use of a habitat quantification tool (HQT) designed by EDF and local stakeholders to evaluate the current quality of habitat for Swainson’s hawk and compare restoration alternatives to optimize habitat outcomes. This will be the first time the HQT will be used as a mechanism to help allocate public funding to the most high value habitat improvements in California.
