Highland Lakes Chapter

Highland Lakes NPSOT Meeting: Saturday, 15 November “Galls, Leaf Mines, and OtherAnomalies”

Valerie Bugh, a local naturalist specializing in the arthropods of the Austin area and interests in taxonomy and photography, is the speaker for Highland Lakes Native Plant Society of Texas’s Chapter Meeting on Saturday, 15 November, 1:00-3:00 p.m. at the Marble Falls Library, 101 Main Street.

Val runs the Fauna Project at the Lady Bird Johnson Wildflower Center, leads insect/wildflower discovery walks, teaches entomology and plant classes, provides insect/spider identifications, gives talks to local organizations, and is the author of pocket guides to “Butterflies of Central Texas,” “Spiders of Texas,” and “Unusual Insects of Texas.” Her website may be found at  http://www.austinbug.com/index.html

Val’s Presentation, “Galls, Leaf Mines and Other Anomalies” will address:

• The odd “things” on an attentive gardener’s plants that aren’t easily identified and don’t have an obvious explanation.

• Many of these phenomena are the result of organisms from kingdoms other than plants, often animals and fungi.

• The relationships between these disparate groups are frequently complex, sometimes surprising, and always intriguing.

• To better understand the ecology of any thriving habitat, we’ll look at growths, attachments and damage on plants with a focus on what caused them and why.

This meeting will count as one hour of Advanced Training credit for Master Gardeners, and one hour of Advanced Training Credit for Master Naturalists.

The business portion of the meeting is during the first 30 minutes, followed by the presentation.

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.
