Boerne Chapter Member Spotlight: Wilt Shaw

Wilt Shaw

NPSOT Member since 2002
Boerne Chapter President 2009-2010

Wilt Shaw, a long-standing member of NPSOT Boerne and its tenth past president, is featured in this month’s Spotlight. For several years, he has led the NICE! Plants of the Month selection committee. Through a recent interview, I gained valuable insights into his experiences and learned a great deal about the natural world.

Wilt’s fascination with nature began during his childhood in San Antonio, where he frequently explored San Pedro Park. There were frequent visits to his paternal grandparents’ farm outside Natalia in Medina County, which featured a creek. These experiences sparked his interest in plants, animals, and water, forming the foundation for his lifelong passion. While Wilt possesses a broad knowledge of many topics, this spotlight focuses on his history and volunteer work.

After graduating from Central Catholic High School in San Antonio, Wilt joined the U.S. Army and was stationed in Germany as a paratrooper, where he became somewhat fluent in German. Following his military service, he earned degrees in mathematics and physics from St. Mary’s University. Wilt’s career as an exploration geophysicist led him to Dallas and Indonesia. His family enjoyed living in Indonesia for nine years, which allowed his children to complete high school there.

Upon retiring, Wilt and his family relocated to the Boerne area, where he rekindled his love for nature and exploration. Motivated by his friend Dr. Bill Ward, Wilt became a volunteer at the Cibolo Nature Center shortly after its opening and continues to serve at the Center for Conservation. For years, he participated in the outdoor classroom program, educating local children about nature. Currently, he monitors the nesting patterns of Great Blue Herons at the Cibolo Preserve, a 600-acre area adjacent to the Cibolo Nature Center.

Encouraged by his friend J.W. Pieper, Wilt became a Texas Master Naturalist. Together, he and J.W. formed the Cordillera Nature Club, an organization that has for many years educated their neighborhood on many aspects of the natural world. For over twenty years, he has served as an Interpretive Guide at Honey Creek State Natural Area on Park Road 31 off State Highway 46. Wilt is also a member and former president of Friends of Guadalupe River State Park.

He has contributed to the preservation and maintenance of the Boerne City Campus Natural Area, located behind the Patrick Heath Public Library. As a Texas Parks volunteer, Wilt helps at the AB Kronkosky State Natural Area, seven miles west of Boerne. He also conducts butterfly surveys in Kendall, Comal, and nearby counties for the North America Butterfly Association.

Wilt is an avid birder and photographer, capturing images of plants, trees, birds, reptiles, mammals, insects, and pollinators. Many of his photographs are shared on INaturalist, a global digital platform.

At home he enjoys reading science books and the occasional novel, exploring mathematics articles, solving Sudoku puzzles, and (hopefully) completing New York Times crosswords. He subscribes to Scientific American and Natural History Magazine. In past years he and Sylvia were dedicated runners and walkers but have now changed to walking and going to the gym. His property at Cordillera Ranch is comprised of 95% native plants, demonstrating his dedication to the Texas ecosystem. Wilt and Sylvia enjoy spending time with their three children, eight grandchildren, and one great grandchild.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
