Lennard Nadalo

Lennard A. Nadalo, MD has a long-standing interest in Ecology, as seen in the survival of millions of plants, animals, and insects during the ongoing climate change. He holds a BA in the Natural Sciences, Suma Cum Lada granted to him by North Park University, and an MD degree with Honors from Northwestern University Medical School. In each of his duty assignments in the military, he learned the history and ecology of the area where he served. Lennard was born in Chicago, Illinois, where he helped maintain a family, “Victory Garden.” He created a backyard in a new home in San Antonio, TX, Eastern Maryland, Hawaii, and the Northwest USA. He has developed a Certified Wildlife Habitat in Parker, Texas, and is currently in Dallas, Texas.

Dr. Nadalo is a Certified Dallas County Master Gardener (2020). He is also a current member of the Native Plant Society of Texas, Dallas Chapter. He belongs to the Speaker’s Bureau of the Dallas County Master Gardeners and is a member and lecturer in the Allen Garden Club and a member of the Garden Club of Dallas.

“Wildscape” Gardening: Creating an Urban Wildlife Habitat

As urbanization expands, there is an associated decrease in natural resources available to birds, butterflies, and other native species. The generation of “heat islands” and the lost opportunity for citizens […]

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.
