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

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
