While most people throughout the Brazos Valley were busy in early December making preparations for the rapidly-approaching holiday season, Texas A&M Center for Mathematics and Science Education (CSME) researcher Dr. Craig Wilson was having visions of greater numbers of Monarch butterflies in his head, thanks to timely assists across Aggieland, from mayors to general citizenry.

“I pledge. …” I most often hear these words when I am standing inside a classroom in a school somewhere and The Pledge of Allegiance of the United States of America is being recited first thing in the morning by a teacher and students, each facing a flag in their classroom, a hand over the heart. This is an expression of allegiance to a flag (Colonel George Balch, 1887).
But now, I am hoping to hear an additional pledge (National Wildlife Federation, 2015) spoken. It is a pledge that requires action on the part of mayors and citizens throughout these United States, united in an effort to save the annual migration of the Monarch butterfly (Danaus Plexippus) from the state of Michoacán in Mexico to the Midwest states, northernmost states and on to Canada. This is achieved in three-to-four generations as the migrating Monarchs arrive in the spring from Mexico, funneling through the critical milkweed habitat that is Texas, lay their eggs on milkweed plants and die. The offspring mature and fly north to Oklahoma and Kansas, lay eggs and die. The next generation will repeat this effort, reproduce and die.
It is the fourth generation on which the species pins its hopes, for they must multiply magnificently. The adults must feed voraciously on nectar to build up fat reserves. The adults must enter sexual diapause before a mass migration is triggered in late fall, at which point they head south to Mexico. Each butterfly has the ability to fly the 2,000 miles to reach the state of Michoacán, an area they have never been. It is an area that their great grandparents left in the spring as part of the largest insect migration in the world — a migration that is under threat. It is a miracle of a migration.
It will take a miracle to sustain it. The Monarch population used to number 1 billion in the early 1990s. There has been a precipitous decline to 33 million in 2013, recovering slightly to 57 million in 2014 and, optimistically, to 100 million in 2015. The main cause is lack of milkweed, which is the only food source for the nascent Monarch caterpillars. It is critical that habitat is restored or created where milkweeds and other wildflowers that serve as nectar sources for all butterfly species, bees and other pollinators will thrive. That is where the Mayors’ Monarch Pledge comes into play. The mayors who sign do so, agreeing to take specific actions. Actions speak louder than words. You can learn more about those here.
It was to that end that I led a group of delegates to bring the Monarch Pledge to the attention of Mayor Nancy Berry of College Station, Texas. Mayor Berry and David Schmitz, director of the Parks and Recreation Department, made a receptive audience. They were willing to be educated in the biology of both the Monarch butterfly and of native Texas milkweed species of which there are about 30, the more common in the wild being Antelope Horn (Asclepias asperula) and Green Milkweed (Asclepias viridis). The two species most often found in private gardens are Butterfly Weed (Asclepias tuberosa) and Tropical Milkweed (Asclepias Curassavica), the latter needing to be cut back in the fall before the Monarchs migrate through the Brazos Valley.
Mayor Berry listened, then questioned both the delegation and Mr. Schmitz to decide upon the feasibility of acting on the actions recommended. Then she took action. She will sign the Mayors’ Monarch Pledge. She will issue “a proclamation to raise awareness about the decline of the Monarch butterfly and the species’ need for habitat” on January 28, 2016, at the scheduled City Council meeting. Because of Mayor Berry’s enthusiastic support, College Station will be joining 48 other mayors to date nationwide who have stepped up and said, “I pledge. …”
