Fredericksburg Chapter

Get the Dirt on Soil – Learn How Your Soil Can Hold More Water, September 26

Peggy Sechrist, an advisor to the Soil for Water Initiative (a project of the National Center for Appropriate Technology), will share key soil health principles that have been emerging in the field of soil science for the last 10 years. This is a timely topic for a drought stricken region. She will be addressing the monthy Fredericksburg Chapter meeting at 7:00 September 26 at St. Joseph’s Halle (212 W. San Antonio St., Fredericksburg).

“Peggy has 35 years of regenerative agriculture and ranching experience in the Hill Country,” noted Deborah Simmons, President of the NPSOT Fredericksburg Chapter. “Her talk will be beneficial for everyone regardless if you manage a large ranch or have a small city yard.”

Sechrist is a practitioner of holistic management, an approach to land management the helps regenerate degraded landscapes and improve the livelihoods of the people living on them. She and her husband, Richard, have been restoring native species on the ranch they have managed for 30 years. She has been a Professional Certified Educator in Holistic Management since 1992 and is currently an advisor to Elizabeth McGreevy’s “Project Bedrock.”

“Through application of holistic management, we were the first ranchers in Texas to create a certified organic, grass-fed beef operation in 1995,” said Sechrist. “Because of this management we have seen the return of Eastern gamma grass along the riparian areas and Indian grass returning to the uplands along with many other diverse species of native plants. I’m looking forward to sharing this information and answering questions at the upcoming meeting.”

About the Region

New Braunfels, the location of our Fall 2024 Symposium, straddles both the Edwards Plateau Ecoregion and the Blackland Prairie ecoregion. Interstate 35 divides the city of New Braunfels; its path through the city closely parallels the boundary of these two ecoregions, with the Edwards Plateau on the west side and the Blackland Prairies region to the east. 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 four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
