When McAllen Mayor Jim Darling heard the monarchs were in trouble, he decided to take action.

Darling signed the National Wildlife Federation’s Mayors’ Monarch Pledge, committing to restore habitat for the iconic butterfly in McAllen, Texas, and encourage its citizens to do the same. He joined other signatories in Mexico, Canada and the United States — nearly 80 in Texas alone.

The pledge outlines actions communities can take that will help, from striking milkweeds (Asclepias spp.) from noxious plant or “weed” lists to planting native nectar plants in medians and public rights-of-way. Mayors must agree to initiate at least three actions within a year from taking the pledge; McAllen and San Antonio both pledged to take all 24 actions suggested by NWF.

Twenty years ago, more than one billion monarch butterflies (Danaus plexippus) migrated south to Mexico for the winter, roughly following Interstate Highway 35 (which reaches as far north as Duluth, Minnesota) through the middle of the U.S., right over Texas. In the winter of 2014, only 60 million made the trip; the North American monarch population has declined by more than 90 percent over the past two decades. Scientists attribute the decline to degradation and loss of habitat in both the U.S. and Mexico. That’s where the pledge comes in.

“We have one of the World Birding Center sites, Quinta Mazatlan, and the manager asked if I was interested in taking the pledge,” Darling says. “I had read about the monarch’s journey and thought, ‘What a journey that is,’ but I wasn’t aware of their habitat needs.” Schools, city parks and other facilities throughout McAllen have installed native plant gardens, and Darling even planted one in his backyard.

Colleen Hook, the Quinta Mazatlan manager who started the ball rolling, stresses the benefits of having the mayor involved. “I can pick up the phone and call city departments or businesses and say I’m calling on behalf of the mayor. It makes it a citywide project.” NWF, she adds, provided tools and a roadmap for increasing habitat in the city.

The Mayors’ Pledge focuses on partnering with other groups and individuals in a community, creating monarch conservation networks for each city that signs. It also complements other NWF programs, says Rebeca Quiñonez-Piñón, outreach coordinator for a Central Texas network that includes Monarch Heroes, a program encouraging children to help create gardens.

“I love our garden,” said Rafael Gillion, a fifth grader at Zilker Elementary in Austin. “It brings back our monarchs, and I get to help them survive while I learn in science class. I am proud of our school for helping.” Likewise, seventh-grader Jane Lange says Houston ISD’s Tanglewood Middle School wants to become “a more eco-friendly place, especially to the monarchs. We added milkweed and designed places for [caterpillars] to hang their cocoons, plus small puddles with rocks and lots of flowers.”

“Anyone can create a small habitat, with food, water, cover and a place for raising young,” says Quiñonez-Piñón. “Lots of small pieces of habitat add up, and it definitely makes a difference.”

Bring Back the Monarchs, a Native Plant Society of Texas program, also encourages collaboration to increase urban monarch habitat, providing public institutions with grants to purchase plants. NPSOT awarded 28 grants totaling almost $9,000 this spring; recipients range from public schools and church pavilions to courthouses and city and state parks.

Master naturalist Carol Clark heads the program, which accepts grant applications from December to February each year. “Gardens need a good ratio of milkweed to nectar, a good seasonal mix and diversity of plants, and a long-term care and maintenance plan,” Clark says. “Since monarchs funnel through Texas twice a year, it is crucial to have milkweed for them to lay eggs and nectar plants for fuel, especially in the fall.”

One grant recipient is the Dona Marie Clubhouse, a nonprofit psychiatric rehabilitation day center near Houston. Dona Marie volunteer Sharon Smith proposed a butterfly garden to the members, collecting seeds and obtaining a grant from NPSOT. After volunteers from several organizations helped plant the garden, Smith says nearly 100 caterpillars made their chrysalises on the home’s sunroom. “That got everyone interested because they could see it happening,” she says.

Through its Project Milkweed, funded by the U.S. Fish and Wildlife Service, the Wildflower Center collects wild seeds and propagates native milkweeds. These species are adapted to the specific weather, pests and other conditions in Central Texas and are known hosts for monarch larvae (or caterpillars). Now in its third year, the project has donated more than 1,800 plants to NWF and other programs and provided more than 100,000 seeds to commercial and noncommercial growers.

While collaborations are crucial, individuals play a key role too. “Each citizen can make a difference,” says Hook. “It’s like pearls on a necklace. Your house is one pearl and your street becomes a string of pearls, a corridor for birds and butterflies. That is pretty powerful for such a simple step.”

Darling finds it symbolic that monarchs freely travel all the way from Mexico to Canada. “There are no borders for the butterflies,” he says. And with enough native plants along the way, no barriers, either.
