About the Chapters

Members of the Native Plant Society of Texas are encouraged to join and participate in our local chapters. 

Local chapters across the state help promote the Native Plant Society of Texas mission while providing a social context which many members enjoy. Each chapter chooses projects according to the interests of their members, and organizes local field trips, meetings, plant sales and other events.

Chapters enjoy the strengths and legal benefits of being one incorporated non-profit organization. Our state office handles common administrative work and is the center point for statewide programs.

If there is not a chapter in your area, please consider starting one. The state office will provide support.

Chapter Map

We have chapters in many areas of the state.

  • Use the map below to get a general idea of where chapters are located.

  • Use the checkboxes in the upper right corner of the map to view the cities (Chapter pins), counties (counties served by a particular Chapter), or Ecoregions (Level 3 Ecoregions) where the Society has active chapters.

Chapters do not limit their membership to any particular city or county. Many members live outside the city or county that their chapter serves. Some members actually choose to join chapters not based on geography but because the meeting time is convenient to them or because it’s easier to get to. Members may join and participate in any chapters of their choice.

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.
