Have you wondered which native tree will shade your backyard, not drop leaves in the pool, and also doesn’t need a lot of water? Do you have acreage and are trying to restore your landscape after fire or grazing? Are you wondering what to consider when picking trees for color or to create a visual screen between you and the neighbors without irrigation?

Rachel Sarlls, Regional Urban Ecologist with the Texas A&M Forest Service-San Antonio region, addresses these questions and others during this month’s meeting. Her topic: how to select the perfect native tree for your various spaces and how to care for them.

“Our region has suffered greatly from drought for many years, oak wilt, severe freezes and wildfires.” Jonathan Watt, president of the Fredericksburg chapter of NPSOT, commented in introducing this month’ topic. “Her talk will be interesting for new homeowners and long-time landowners alike,” Ms. Sarlls has been with Texas A & M Forest Service since December 2024. She graduated from Sam Houston State University with a bachelor’s degree in plant and soil sciences.

“I’m looking forward to speaking about native trees that do well in the Edwards Plateau and to answer everyone’s tree-related questions,” said Sarlls. “It’s so important to learn about the best trees to plant on your property so that you can take care of them and enjoy them for years to come.”

Sarlls is an International Society of Arboriculture (ISA) Certified arborist with specialized qualifications in tree risk assessment and Oak Wilt management. She has worked as an arborist in the Houston region, managing work from tree removals and pruning to fertilization and planting. Her passion is for empowering communities through education and outreach, to help people understand the vital role trees play in urban environment and how to effectively care for them.

NPSOT Fredericksburg holds its monthly meetings on the 4th Tuesday of the month at St. Joseph’s Halle. A social time with snacks  begins at 6:30 p.m.; the meeting starts at 7 p.m. Meetings are free and open to everyone. The public is invited to attend in person or via online streaming.

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.
